Show Images Attached To A WordPress Post Without Plugins

I’m not sure what you mean? If you mean how would you get the images to a specific post, you would have to know it’s ID as you can’t get attachments via a post title (name) just in case there are two posts with the title.

For this to work the main image will always have to be the last one.

Add in this on line 8, that’s before the foreach starts:

Then place the next part inbetween line 9 & 10:

I’m unable to test that at the minute, but I think it should work. Let me know if you get any errors & I’ll fix them asap.

Hi Dai,

It is timthumb that is used on the wallpaper site. It should cause an error if it isn’t, but is GD available on your server?

Have you checked to see if timthumb created a folder called ‘cache’. That’s where it places it’s created images. If you don’t have one, try creating the folder (in the same directory as timthumb) and make it writeable.

That’s all I can think of that would stop timthumb from working properly. Hope it helps.

Hi Bueno,

Well it’s pretty easy since you already have all the attachments ordered by menu order (that’s the numbered order you set in the WordPress uploader). All you have to do is only access the first one instead of running the foreach.

So to get the URL to the first image your code might look something like:

As you can see you still need to pass it through the wp_get_attachment_url function. You just don’t need the loop as you only want the first item in the array.

One thing to note. If you are wanting to use custom thumbnails and you want to grab a thumbnail size instead of the full size image you will need to use wp_get_attachment_image_src instead. The first parameter is the ID & the second is the name you gave to the thumbnail size when you set it up in your theme.

That will return an array of which the URL to the image is in [0].

Hope that helps.

Sorry that was my fault. Using [0] won’t work as the key is the ID of the attachment. You’d need to do this instead.

Giving the error you get is always a good idea.

From looking at the code though, you haven’t closed PHP wrote your image element & then reopened it.

It should go like this:

Nope definitely outside. The syntax error is showing because it is finding an open PHP tag inside a PHP tag.

The reason it’s not working is simply because I forgot to add a little bit to line 9 of the code I posted above. It should be:

I’ve just tested it on my local server & it works fine.

Hi Bueno,

No problem.

Thank you for any donation are able to give, don’t forget if you don’t like to donate you can always buy me a present from my Amazon Wishlist instead, just click the wishlist button under any post.

I’m afraid it’s not that simple (and your code got a little mangled by WordPress).

You have to place it in a template file. There is an explanation of how to create them on the Codex as it would take to long to explain here in the comments. Although the easiest way is to copy the page.php or post.php file.

It’s not the easiest thing to explain, sorry. I’m going to try and do some tutorials on how to do some basic things in WP like create new templates, but it’s hard to find time at the minute. 🙁

Hi Greg,

That function get_the_post_thumbnail() is a WP function used to get thumbnails from a list that have been predefined in your theme, generally in functions.php.

If you want to use the size generated by ‘bones-full-662’ all you need to do is do this inside your post loop:

You can of course change the class to whatever you like.

If you want to add another thumbnail size you would need to add it to the list of sizes that WordPress needs to generate. You can do that using:

where ‘unique-key’ is a meaningful key you use when telling WP which thumbnail it should get. The two numbers are width & height respectively & the last bool is whether to hard crop the image or not.

You would place that line next the the other add_image_size() function calls that are somewhere in your theme. Like I said, they are probably in functions.php.

Once you’ve done that you will need to run a thumbnail regenerator plugin like the one by Viper007Bond. You only need to run it once, and then it can be deactivated & removed. This will run through all your previously uploaded images & create the newly created thumbnail size for each one.

Hope that helps answer your question. If you have any problems please let me know. 😉

No problem Martin, hope it works for you. 🙂

Hi Marco,

Everything should be available under the $attachment variable. I can’t remember what the names are, but you can print_r($attachment); to see what the field names are.

Hi,

That would be because it is set to order by ‘menu_order ID’. That means order by the order shown in the gallery or, if one has not been set, order by the ID. The ID is, in most cases, the order which you uploaded them.

The only way I can think to order by the filename is to do it manually. Get WordPress to give you back your attachments, use the code:

Store them in an array then use a PHP array sorting function to sort them by the filename. Unfortunately I don’t have much time to go into much more detail than that, but hopefully it does help.
