WordPress Plugin: The Attached Image

December 20, 2008 / WordPress Plugins / by Paul Robinson / 556 Comments

This post was published back on December 20, 2008 and may be outdated. Please use caution when following older tutorials or using older code. After reading be sure to check for newer procedures or updates to code.

Warning

This plugin is here for legacy support only. WordPress now contains a featured image system which does the job of this plugin from within the WordPress core. Please try to avoid using this plugin unless it is unavoidable. I will still provide limited support via comments or email, but it will no longer receive any updates or bug fixes. If your theme needs to be updated to use the new featured image system instead of this plugin, I am available for hire.

What’s This Then?

The Attached Image is a simple plugin that packs quite a punch. It shows the first image attached to the current post. For example. If you have your home page set to 5 posts and you use this plugin it will show the first image attached to each of those posts. For a working example see celeborama.net which uses it to grab the picture you see floated to the left of each post.

It was inspired by a plugin wrote by Kaf Oseo, but when support & updates were no longer available & a recent upgrade of WordPress meant it didn’t work exactly like it used to, I decided to take on the challenge of remaking it using the newest WordPress functions available.

What’s It Do?

It has a lot of features, if you want to see them all then check the options list a litte further down the page. For now though here are some of the major ones that most people look for:

Can show the full, medium or thumbnail sized image attached to the current post. Can now show custom thumbnail sizes added by WP 2.9’s post thumbnail support. Check here for more info.
Can make a hyperlink around the image that points to the post the image is attached to, the full image, the attachment page or a custom URL using custom fields on a post by post basis.
If more than one image is attached to a post then the image to be shown can be changed using the WordPress gallery page. Just pull the image you wish to show right to the top of the list and press save.
Can be returned instead of echoed so the output can be stored in a variable for developers to use as they wish.
Can show a default image if no image is available. Also changeable on a post by post basis via custom fields.
and more…

How Do I Install It?

It’s actually really simple to install. The hard bit is deciding where you want the image to go, but that’s entirely up to you. Here are the instructions you need to get it up and running:

First go and get the plugin. Either from here or using WordPress’ new plugin installer (available since WP 2.7). Just search for the attached image or Paul Robinson.
Unzip & place the folder into the wp-content/plugins folder. (I’m going to assume you’ve done this)
Go to the plugins page of WP & activate the plugin. (Also assumed as done)

Go into the template editor & find where you would like the image to show. It must be within the loop which looks something like this:

    <?php if (have_posts()) : ?>
		<?php while (have_posts()) : the_post(); ?>
        	<!-- Some HTML will be here -->
        <?php endwhile; ?>
    <?php endif; ?>

<?php if (have_posts()) : ?>

<?php while (have_posts()) : the_post(); ?>

<?php endwhile; ?>

<?php endif; ?>

At the point you have found, place <?php the_attached_image(); ?>
Go to the ‘The Attached Image’ options page under the WordPress Appearence menu.

So What About The Options

Functionality Options

This option allows you to switch on and off the perma functionality for in post image. This checks the post content for an image and grabs the image with the number you have asked for. If that number of image is not available it will show your specified default or return with nothing. Just press the checkbox & put in a number. It starts at 1 not 0 like some may think, so if you want to get the first image in the post press the checkbox & type 1 then save. This type of functionality can also be accessed on a post per post basis using the custom fields as explained later in this documentation. This has been extended with a new option to pick a thumbnails size to use. This will only work if the images were uploaded with WP, if they were not or they are linked in from a external source it will default to showing the full sized image.

General Options

Well The Attached Image now comes with a options page so you can alter what it does from the comfort of your WordPress dashboard. The Attached Image is all about adding a feature to your blogs design & because of that I have added it under the Appearance menu. Here is a description of all the options and what they do. First the general options:

Image Size: This is the size of image you would like to use. As of version 2.2 it supports WordPress’ generated thumbnails, medium size, large size images, and of course the original full size image. You can now specify a size using a function call to override the options page. This is great if you want to call the plugin twice on two template pages & want to use different size image. Use img_size= and then either full, large, medium, thumb or custom, for more about custom check this post. Use ampersands (&) to seperate parameters. Use ampersands (&) to seperate parameters.
CSS Class: This is the class that you would like placed in the image tag. The default is attached-image and can be styled as normal through a CSS stylesheet. This option is so anyone who already has a class can use that if they wish. You can also call a different CSS class using function call parameters again options are seperated by ampersands (&). CSS class’ parameter is css_class Don’t use spaces in CSS class names when using this method. An example of both image size & css class together would be this. the_attached_image('img_size=thumb&css_class=custom-class');
Custom Image Size: Here you can input a custom image size. Beware, this uses the inbuilt width & height attributes of the image tag & as such can degrade picture quality if used too aggressively. Please use with caution.
Default Image Path: A simple one. This is the path to a default image if you wish to use one. Empty or leave the box empty to disable it. Very Important the image path must be from the WordPress root & not your hosts root, it must also start with a forward slash (/). So if your blog is in http://example.com/blog/ and you kept the image default.jpg in the wp-content folder the path would still just be /wp-content/default.jpg and NOT /blog/wp-content/default.jpg. It is also NOT the ID of another image.
Image Link Location: Do you want a link to be placed on the image that is produced & if so where do you want it to point. The possible options are no link, post, image & attachment page. I think it’s pretty self explanitory what they do. You can also provide a custom link on a post by post basis, more on that in the custom fields section further down the page.
Image Alternate Text:: Allows you to choose what the default alternate text for the image should be. You can choose either image filename, image description, post title or post slug. The description is taken from the description field that you can fill in when uploading an image via WordPress’ uploader. If one isn’t provided it falls back to the images filename. A custom value may be input via custom fields, see Custom Field Info below.
Link Title Text:: This is the text placed in the title attribute of the hyperlink placed around the image. This will only have an effect if you do NOT have Image Link Location set to No Link. The options are the same as the alternated text & a custom value can be input via custom fields, see Custom Field Info below.

Advanced Options

Now for the advanced options. Please be careful with these. Selecting the wrong option can result in the plugin not working correctly. I will at some point try to add a reset to default for instances where accidents have occured, until then though please be careful. Thanks.

Generate An Image Tag:: Fairly obvious… Whether to make an image tag or just place the full URL to the selected size image onto the page. If a link location is selected then it will also create the selected hyperlink around the URL. This can be useful to some people so feel free to be inventive.
Echo or Return:: Also fairly obvious, if you are a coder. Tells the plugin whether to echo out the output or return the output ready for processing by PHP. Can also be used to do some inventive stuff with the output.
Hyperlink Rel Attribute:: This should allow the plugin to work with most, if not all lightbox scripts. Refer to the documention of the lightbox script for what to place in the rel attribute.
Image Order:: By default the plugin will use the image in the first position of the WordPress gallery page. The image to show can be changed by reordering the images on the WP gallery screen, however you can use this to change which image it will pick. If you change this to 3 it will always try to pick the 3rd image in the WP gallery order. If there isn’t 3 images it will pick the nearest it can get to the 3rd image.

What About Those Fancy Custom Fields?

Some of the options can be changed on a post by post basis through the use of custom fields. These are the available keys, what they do & the values they expect. All of the keys prepended with att so that they are easily recogniseable as for use with The Attached Image & to stop conflicts with other plugins that may use custom fields.

Key: att_custom_img: This field is used to show any image from the WordPress attachment database, even if it isn’t attached to the current post. It requires the ID of the image you wish to show. It can generally be found out in the media section of WordPress.
Key: att_default_pic: Allows you to override the default picture that is to be shown if no picture is available. Path rules are exactly the same as the previously mentioned option.
Key: att_width & att_height: Pretty obvious, but it allows you to change the width & height of the image. It again uses the in-built browser method of resizing, so again be careful. Also please remember these are two seperate keys, I have listed them together but you must use two custom fields one for width & one for height.
Key: att_custom_link: Allows you to chose a custom URL for the hyperlink to go to. It will override the setting chosen in the options page for that single post. If you have selected no link in the options using this will override it and create a hyperlink for that single post.
Key: att_custom_alt: Allows you to chose a custom alt attibute to be placed in the image tag.
Key: att_custom_link_title: Allows you to chose a custom title attribute to be placed in the hyperlink. Only has an effect if Link Image Location is NOT set to No Link.
Key: att_in_post_image: This feature was requested by Jake Garrison. It allows you to display an image that is inserted into the post & not attached via the WP uploader. It scans for img tags in the post and places it where ever you place the plugin call. Options are a number starting from 1 of the img tag you wish to pic from the post. 1 will pic the first, 2 will pic the second and so on. If there isn’t a img tag matches the number picked it will leave a blank space (return false). Example. If you choose 4 and there are only 3 images in the post in will return blank (return false).
Key: att_in_post_image_size: Allows you to choose the thumbnail size for the in post image function. This only works if the image was uploaded via WP. If it wasn’t or is linked from an external source it will default to the full sized image.

Custom Queries

The ability to easily use custom queries was added as of version 2.5. There is now a second parameter for the query object. All you need to do is hand the query object over to the plugin. Here is an example:

//Custom Query Example
$my_query = new WP_Query('showposts=2&cat=3');
while($my_query->have_posts()) : $my_query->the_post();
  //Other Post Details
  the_attached_image('img_size=thumb&css_class=image', $my_query);
endwhile;

//Custom Query Example

$my_query = new WP_Query('showposts=2&cat=3');

while($my_query->have_posts()) : $my_query->the_post();

//Other Post Details

the_attached_image('img_size=thumb&css_class=image', $my_query);

endwhile;

It should be fairly easy to follow. All you need to do is look for the variable that WP_Query() is assigned to & hand it to the attached image.

Wait Up… I Have More Questions!

Really? You do! Well then your already in the right place. You can either leave a comment on this post, or if you prefer, you can send me an email using the contact page.

What If I Find Something I Want Added Or I Find A Bug?

Well you wouldn’t be the first. Most of the features now included with The Attached Image are there through requests made in the comments section, just scroll down & have a read. If you have found a bug or you want to request a feature then the process is the same as the last question. Leave a comment on this post or drop me an email via the contact page.

Alright… Say I’m Feeling Kind…

Ahhh. Say no more. If you are feeling generous then you can buy me a cup of coffee or two using the Paypal donate button just below.

If that’s not your sort of thing then you can always donate some money straight towards my hosting bill with Dreamhost using the button below. Dreamhost take payment via Paypal so you know it is safe & secure.

That It?

Yep. I’d just like to say a thank you to everyone who has downloaded, used, supported, commented on or even just looked at my plugin. It might be me who writes it, but without you guys out there to use and appreciate it there wouldn’t be a point. Thank you so much.

Also a little extra thank you to Alisher, Brian Wood, Steve, Jasper Visser, Jennifer the scriptygoddess, and RougeDeals. All these lovely people suggested a feature that got added to The Attached Image or have identified & helped fix a bug. Also a final thank you to everyone who has linked back to me and helped popularise The Attached Image.

Ya, Finished Now

Actually no, not quite.

Legacy Overrides

These are a list of legacy parameters that allow you to override the values set in the options page. This is useful if you want to have more than one call the the_attached_image() on different pages in your template, but you want them to show different size images, or remove the link and other things. Basically it allows you to call the plugin twice, but have it do two different things. The parameters are entered in Query String format an example is the_attached_image('img_size=medium&link=image&css_class=featured-image');.

img_size: Changes image size to be pulled back by WordPress. Options are thumb, medium, large & full, or custom. Default is thumb.
css_class: The CSS class to place inside the image tag.
img_tag: Whether or not to echo the URL in an image tag. Options are true or false. Default is true.
echo: whether to echo or return the output. True will echo, false will return. Default is true.
link: Where you want the link to go. Will only work if href is set to true. Options are none, post, image and attachment. It is also possible to use a custom URL via the custom fields, please refer to the custom fields section above for more. Default is post.
default: The path to a default image if one is wanted. The path must start with a forward slash and be based from the wordpress directory, not your hosts directory. Options are false & a path to the image. Default is false. Can also be adjusted via custom fields, again check above for more.
width & height: Two seperate parameters that do the obvious thing. The set a custom width & height for all images. This only resizes using the image tag width & height attribute, as such quality will suffer greatly when resizing too much either way. Also adjustable using custom fields, check above for more.
image_order: Allows you to change which image the plugin uses from the WP gallery page. Normally, if there is more than one image, the plugin will pick the image marked in 1st. This allows you to change that. If there isn’t a picture at the position then it will take the pictures as near to that number as possible. Default is 1
rel: The rel attribute is generally used to add lightbox scripts. Just put the word shown by your lightbox instructions here and all should work as long as href is set to true & link is set to image, since there has to be a link and the URL to the full image for the lightbox script to work.
alt: Allows you to choose what the default alternate text for the image should be. You can choose either image filename, image description, post title or post slug. The description is taken from the description field that you can fill in when uploading an image via WordPress’ uploader. If one isn’t provided it falls back to the images filename. A custom value may be input via custom fields, see Custom Field Info above.
title_link: This is the text placed in the title attribute of the hyperlink placed around the image. This will only have an effect if you do NOT have Image Link Location set to No Link. The options are the same as the alternated text & a custom value can be input via custom fields, see Custom Field Info above.

If You Are Still Using An Old Version Without The Options Page

You should really upgrade to the latest version so you can use the new options page, but if you are one of those people who just loves the old school (and why not) then here is a list of parameters. Custom fields are still exactly the same so please use the list above.

img_size: Changes image size to be pulled back by WordPress. Options are thumb, medium, large & full. Default is thumb.
css_class: The CSS class to place inside the image tag.
img_tag: Whether or not to echo the URL in an image tag. Options are true or false. Default is true.
echo: whether to echo or return the output. True will echo, false will return. Default is true.
href: If you plan to use the link feature (which will automatically generate an href around the image) then you must set this to true first. Options are true or false. Default is false.
link: Where you want the link to go. Will only work if href is set to true. Options are none, post, image and attachment. It is also possible to use a custom URL via the custom fields, please refer to the custom fields section above for more. Default is post.
default: The path to a default image if one is wanted. The path must start with a forward slash and be based from the wordpress directory, not your hosts directory. Options are false & a path to the image. Default is false. Can also be adjusted via custom fields, again check above for more.
width & height: Two seperate parameters that do the obvious thing. The set a custom width & height for all images. This only resizes using the image tag width & height attribute, as such quality will suffer greatly when resizing too much either way. Also adjustable using custom fields, check above for more.
image_order: Allows you to change which image the plugin uses from the WP gallery page. Normally, if there is more than one image, the plugin will pick the image marked in 1st. This allows you to change that. If there isn’t a picture at the position then it will take the pictures as near to that number as possible. Default is 1
rel: The rel attribute is generally used to add lightbox scripts. Just put the word shown by your lightbox instructions here and all should work as long as href is set to true & link is set to image, since there has to be a link and the URL to the full image for the lightbox script to work.
alt: Allows you to choose what the default alternate text for the image should be. You can choose either image filename, image description, post title or post slug. The description is taken from the description field that you can fill in when uploading an image via WordPress’ uploader. If one isn’t provided it falls back to the images filename. A custom value may be input via custom fields, see Custom Field Info above.
title_link: This is the text placed in the title attribute of the hyperlink placed around the image. This will only have an effect if you do NOT have Image Link Location set to No Link. The options are the same as the alternated text & a custom value can be input via custom fields, see Custom Field Info above.
in_post_image: This feature was requested by Jake Garrison. It allows you to display an image that is inserted into the post & not attached via the WP uploader. It scans for img tags in the post and places it where ever you place the plugin call. Options are a number starting from 1 of the img tag you wish to pic from the post. 1 will pic the first, 2 will pic the second and so on. If there isn’t a img tag matches the number picked it will leave a blank space (return false). Example. If you choose 4 and there are only 3 images in the post in will return blank (return false). Can also be set via the custom fields, without setting this parameter using the key above. Warning: This will override the normal function of this plugin if set as a parameter. If you use custom fields the plugin will work as normal except for the posts it is used on.
in_post_image_size: Allows you to pick a thumbnails size for the in post function. Will only work if the image was uploaded via WP. If it wasn’t or it is linked from an external source it will default to the full sized image.

That’s all the parameters, but seriously you should upgrade to the latest version. There is tentative support for the parameter based system, but it is only there as a backup until I can safely assume everyone is using the new options system. Please don’t hesitate to leave a comment if you have problems switching over to the new system, it is a lot better.

Now are you finished?

Yes, now I’m done.

Update: 14/12/2009

I’ve just created a PDF file to show everyone some of the advanced uses available when using The Attached Image. Hope it is of use. 🙂 Advanced Uses For The Attached Image PDF

Update: 07/04/2010

After a few questions about how to use The Attached Image, I have decided that a visual approach is the best way to explain, so here is a video on how to add The Attached Image to your theme.

Hi,

This plugin is basically an updated version of an old plugin that grabbed the first image attached to a post. Meaning the image was uploaded via WordPress’ inbuilt image uploader. If your images were not uploaded to each post (or page) then I’m afraid this plugin won’t be any help.

If I understand you correctly the post-thumbs plugin grabbed the first image inserted (rather than uploaded) into the post (or page) and made a thumbnail from it? You can enable a functionallity on the plugin that does something similar (the checkbox on the top of the options page for the plugin) I’m not sure if that is what you are looking for though.

I hope that answers your question, not sure if it helps though, sorry. If it doesn’t just comment again & I’ll see how else I can help. 🙂

Thanks a lot
– the all-time quickest response I’ve got during two years with WP! :o)
All the images are uploaded using WP’s upload function. The problem, it seems, is that the images are already there. So, I need the plugin to display thumbs from images already in the posts, not just in new posts.
If this isn’t possible, I will have to edit each post – delete the top image – re-upload the same image – and click save.
I was hoping to avoid that – but maybe it’s un-avoidable.
Hope I explain myself precisely enough.
🙂

Ahhh I get what you mean, you have inserting the images in <img> tag inside the posts already. Unfortunately you’ll have to go through all the posts & remove the image tags. Sorry. 🙁

Oh and thank you, I aim to please. 🙂

Sorry forgot. 😛

You shouldn’t need to upload all the images again though. The Attached Image just asks WP for any images that have been uploaded to the current post ran through the loop. If it has one it is shown. If you have images inserted in posts via img tags after you’ve uploaded them via the WP uploader then TAI should still pull up the image you will just have a duplicate (because of the image you manually inserted).

I hope I’m understanding you correctly.

It doesn’t matter if you use the flash uploader or not, it still goes through the same process during upload.

“The Loop” is just a developers term for the section of a template which repeats to show each post. it generally looks like:

while(have_posts()) : the_post();
//some stuff here
endwhile;

while(have_posts()) : the_post();

//some stuff here

endwhile;

As long as the template reference to the attached image is between there somewhere it should show the thumbnails fine. If it isn’t you will got odd things happening such as no thumbs showing or even thumbnails from posts you weren’t expecting.

If you have a link to the website your testing on or you could provide some screenshots via email of the problem your having it would help a lot in troubleshooting it.

Hi again
I’m not sure what you mean with “ran through the loop”…?
Almost all images are uploaded and inserted using WP’s built-in uploader (above the text edit field), uploading one image at a time. After clicking Add an image we’ve mainly used the Browser uploader (not the Flash uploader).
Doesn’t fit with your way of doing it/ a mistake we’ve done?
Any way to make the thumbs just appear?
Thanks for having patience with me

Hi there,

I’m using this great plugin in combination with WPTouch so that I can get thumbnails in an iPhone optimized format. They both work great, but my error logs show this:

:PHP Warning: Invalid argument supplied for foreach() . . . /plugins/the-attached-image/the-attached-image.php on line 580″

Which corresponds to this section of the_attached_image.php file:

foreach($attachments as $id => $attachment) :
		$i++;
		if($i == $image_order) :
			$attachment = $attachment;
			break;
		endif;	endforeach;

foreach($attachments as $id => $attachment) :

$i++;

if($i == $image_order) :

$attachment = $attachment;

break;

endif; endforeach;

Any ideas about what would cause this error?

author

Sorry about not replying, just had to format my computer & I’ve been reinstalling everything. 😛

Anyway. I’m not exactly sure what is going on there. Usually that error would mean that $attachments is empty (or isn’t an array), but if that happens it shouldn’t get to that part of the script since $attachments is checked first. You say it is running ok though despite the error? I’ll see what I can find but it’s very strange.

Yeah, other than this error, the plugin is running beautifully . . . .

One bit of information that I forgot to give in my first comment is that I have placed the code

) twice in the wp touch file — once to display thumbnails on the main page and once to display them on categories.

Not sure if this info changes anything, but I thought I’d include it.

Thanks again for getting back to me. Really appreciate it.

The code in my last message didn’t post . . . let me try it again.

Sorry to be repetitive, but the php line of code won’t display . . . .I tried twice and double-checked that I had done it correctly. Not sure why it won’t show up.

author

Hi again,

I’m not sure why WP truncates the code sometimes. Can you send it to my email addy: pablorobinson[at]gmail[dot]com

I think it’s something to do with the theme I’m using. 😕

Please help!

After activating the plug-in, indeed the first image shows in post but the complete gallery thumbnails also show under main (first image)!

Any advice will be appreciated to make only the first image, thanks!

author

Hi,

That’s really odd. It has never happened during testing so I’m going to assume it is something unique to your blog. The only thing I can think of that would cause that is somewhere on the post/page you have wrote the gallery shortcode [gallery], or your template has it hardcoded into it with do_shortcode('[gallery]'); at some point. Those are the only ways I know to show all of the thumbnails.

Just to be safe though I have just checked through my test blog & there are no problems like that happening.

Sorry if that isn’t much help, but again that’s all the possible problems I can think of. If you still have problems, but can find anything else about the problem it would help alot.

author

Woah! What? lol.

Yeah unfortunately if you re-use an image that is attached to one post in another post it will not count. I haven’t figured out, or rather I don’t think you can, get it to realize that it is actually attached to a post, just not the one you are in. Good idea with switching to nth content image though. 😉

Not sure about the skewing problem though. I’ve had a check through the code & can’t see anything that might be causing it. What exactly do you mean by skewing though?

Edit: I may have just found something, but I can’t test it at the minute. If you want to give it a go here is what I was going to change:

//if image is offsite we try our best to get the image size;
$imagesize = @getimagesize($img_url);
//if not we have to resort to making an empty array to stop PHP taking a fit.
if(!isset($imagesize[0])) {
	$imagesize = array('', '', '', '');	
}

//if image is offsite we try our best to get the image size;

$imagesize = @getimagesize($img_url);

//if not we have to resort to making an empty array to stop PHP taking a fit.

if(!isset($imagesize[0])) {

$imagesize = array('', '', '', '');

}

change it to this:

//if image is offsite we try our best to get the image size;
$imagesize = @getimagesize($img_url);
//if not we have to resort to making an empty array to stop PHP taking a fit.
if(!isset($imagesize[0])) {
	$imagesize = array(FALSE, FLASE, FLASE, FALSE);	
}

//if image is offsite we try our best to get the image size;

$imagesize = @getimagesize($img_url);

//if not we have to resort to making an empty array to stop PHP taking a fit.

if(!isset($imagesize[0])) {

$imagesize = array(FALSE, FLASE, FLASE, FALSE);

}

Basically I think if getting the image size fails it won’t set the width & height to false (so that the width & height won’t be written in the HTML & browser will autodetect width & height). Instead it writes a blank width & height into the source code (which for some reason doesn’t show in FireFox’s source code viewer). Those FALSE should auto set them to false if getting the size fails.

If that doesn’t work I’m up the creek without a paddle since I can’t find anything else that would cause the images to skew. 😕

Oh and welcome back. 😀

I turned on the Pick Functionality and set it to 1, and that corrected my first issue of no new images showing up, which, now, I deduce, was most likely because if I re-used an image it did not count it as an image from the Uploader, hence, the only way for it to recognize the image is to scan the content for the nth image, which is 1.

Secondly, when I turn on the Pick Functionality, it seems like it now skews the image most so than it did when Pick Functionality is turned off.

I have no leads on this issue yet, but hey, I fixed my first problem, so that’s something right?

Thanks for the response. My comment didn’t make any sense because my first comment didn’t actually go through when I hit the submit button. So.. that comment was actually Part 2 of an issue I was having.

The issue was it was using the default image when I re-used an image from the image browser… since the uploader didn’t count it as an attached image, it didn’t see I was using an image at all.

Since you implemented the new feature, I was able to get around this issue by just telling it to use the 1st image in the post… so I am happy it works.

But, yes, when using the 1st image in the post instead of the ‘default’ way to detect images, it is skewing the image, and I think you are right on the money… it is probably not setting the correct demensions. Thanks for looking into this so quickly.

I’ve been neglecting my site for a while, but I am back now! Check it out if you want. I’m glad you still have my link on your site. I was thinking about starting up a wordpress new section on my site where I can suggest my favorite plugins and custom code. So, if I do do that, then I will link back.

Thanks again for the quick reply.

No problems.

I had a feeling some of the comment had gone missing. We’ve been having a few problems with someone abusing the server recently, so you might have pressed submit just as the server had a glitch. 😕 We’ve nearly got that sorted though, I’m going round to whoop the guys ass. 😛

The odd thing about that is, it shouldn’t have a problem grabbing the image size unless you are linking an external image (via URL) & your server doesn’t allow external URL wrappers via getimagesize(). That’s why the empty array was in there, PHP would error if I didn’t provide an array in the pattern it expected, but I should have wrote FALSE instead of the empty strings in the first place. Didn’t have enought coffee that day methinks. 😆

If you do link back it would be awesome. I’ve been neglecting Return True a little too, in regards to new tutorials, I just haven’t had any inspiration recently. I’ve also been really busy building other peoples websites, lol.

Again no problem & thanks. 🙂

I’m hoping you might be able to help me out – I want to insert the PHP code for this plugin manually into a widget in the sidebar.

The reason I want to do it manually, is so that I can use the same argument that refers to the Related post, to retrieve the image from that post, so that I can display the image below the Related Post’s title in the widget ( I am use an plugin called “The Attached Image” to do this).

Is it possible for you to point me towards the code that I can insert into a PHP-enabled text widget please?

The code you would need for that (I’m not sure since I haven’t done it before) would probably be the same as you use for inserting into the template. So something like:
[php light=”true”]

[php]
Should work. I hope that helps. Let me know if that isn’t what you were after & I’ll help as much as possible. 😉

I just updated WordPress and now this plugin shows the same image on all posts on the homepage.

Any advice? It was great before I did the update.

I’m not sure why it has only shown after the update but it is usually caused by the way the query is carried out. If you are using it for the standard WP loop it should be ok, but if it is a custom built loop then it will probably be due to the way that is made. If it is in the default WP loop or the loop is already one of the new WP_Query ones then drop me another line as there must be some sort of bug I haven’t picked up.

Just to let you know though I have tested it in all versions of WP up to 2.8.4 and it seems to be working great.

Hi again – is there a way to feed a specific post ID into this code

I have a separate plugin that generates an array of Post IDs and Titles using this code and since I am an amateur PHP coder, I have no idea how to list each of these posts with the title, followed by the attached image. Any clues would be greatly appreciated!

Well normally you would create a secondary loop to get the extra posts using the parameters provided by WP to limit them to what you want. You can find more about the parameters for custom loops here at WP as their docs are more detailed than I could be in this space. To make a custom loop use this bit of PHP:

$my_query = new WP_Query('parameter=value');
while($my_query->have_posts) : $my_query->the_post();
    the_attached_image('parameters=values', $my_query);
endwhile;

$my_query = new WP_Query('parameter=value');

while($my_query->have_posts) : $my_query->the_post();

the_attached_image('parameters=values', $my_query);

endwhile;

That would allow you to get the array of posts, etc in a way that you could pass to the function. I’m not sure if there is a way to pass the array you have though, since WP requires that the value you give the plugin (due to the functions it uses) is an object set up like WP’s WP_Query object.

Sorry if that isn’t any help. 🙁

I like this plug-in, but I’m running into a problem with multiple invocations of it.

On the index.php and other similar pages (ex: search.php), the medium image size is fine, but I’m trying to use the Full image size for posts.

I’ve tried resetting the query, but it doesn’t seem to work. The medium size still applies to the post.

Any help is appreciated.

Thanks,
SB

I tried re-using some old code for another project which needed multiple invocations. Surprise, surprise, WordPress developers killed the functionality and failed to replace it with an included feature.

This doesn’t work in 2.8, but it did work in 2.3:
