It’s been just over a year now since I released my first plugin which you may all know is The Attached Image, so I thought it was time I released another plugin. I hadn’t actually gone out on purpose to make this plugin, but a client’s website needed a simple Twitter feed plugin & while there are already WordPress plugins out there that do the job they insisted a custom one be built. So I set about making it & rather than have it sit in my WordPress functions folder doing nothing (other than working on the client’s site, of course) I thought I should release it as a plugin for anyone to use.
Latest Info – 04/03/2013
If you have updated the plugin to version 2.5 and are having trouble, please make sure to delete the cache. Either manually or using the button on the options page.
What is Twitter Stream?
Twitter Stream is a very simple plugin originally created as a small function for a client’s website. Rather than have it sit doing nothing in my WordPress functions folder I thought I would extend it and make it into a plugin for everyone to use.
It’s functionality is very, very simple. It is designed to simply grab a set amount of status updates from the Twitter user account you request. If there are enough requests I may add some additional features, but for now it is designed to be very simple and run as quickly as possible while using the least amount of resources possible.
What Features Are There?
- Connect to Twitter securely using oAuth. (required)
- Show the twitter timeline for any public username.
- Choose how many tweets to show.
- A Widget or template function is available.
- File caching to stop API overuse.
- Optional date shown in xx ago format, also links to permalink for the tweet. (Requested by Ron)
- Customizeable via CSS. (see the ‘Can I Style It?’ section below)
- Authentication for better API limiting & ability for protected users to show their tweets.
- @replies now link to the user profile of the user you are replying to.
- #tags now link to the Twitter search page for that hash tag.
- Link to user’s profile, customizable via CSS & via function parameter.
- Follower count can now be shown.
- Retweets can now be shown with normal tweets.
How Do I Install It?
You can download it from the WordPress repository here, and then install it as you would any old style WordPress plugin, which is as follows:
- Download the zip file and unzip it to somewhere, say your desktop.
- With any good SFTP client upload the extracted folder to your
- Enable the plugin in the WordPress plugin page.
Of course you can also install it by using the WordPress auto installer.
How Do I Use It?
Due to Twitter not having a solution for open source applications using oAuth yet, you must follow some slightly more complicated instructions to sign in via oAuth. Comprehensive instructions are provided in the plugin but here is a rough overview.
First you need to register a Twitter App, save the consumer keys you are provided with, then sign in with Twitter. As I said more detailed instructions are provided as you set up the plugin, including tips for what to enter when registering you app.
Finally you can show your tweets using a widget. The widget is a WP 2.8 & up compatible widget. If you are using a WP version lower than 2.8 you should really upgrade for security reasons if nothing else.
If you are a good ‘ol fashioned function user then you can call Twitter stream using:
Providing either a keyed array or an argument list. All the parameters available are listed here.
How Do You Get Round The API Limit?
Now that oAuth has been implemented API requests will be counted against your personal account rather than your servers IP address meaning that shared servers should no longer cause a problem. However to reduce the possibility of overusing the API even further caching is still in use.
Sometimes I Get An Error Message!
There is a built in error message that is shown if Twitter fails to provide a vaild XML file. Reasons for this could be that the Twitter API is down (which Twitter claim is highly unlikely), or the plugin failed to read the cache file. If this happens, and you know Twitter is available, try deleting the cache file which is named
username.cache. You can do that using the brand new ‘delete cache’ button which is shown on the bottom of the authorization page. Just click ‘Twitter Stream’ under the settings menu to find it.
Sometimes The Date Is -xx Seconds Ago?
This is sometimes difficult to get your head around. Simply put it is caused by your servers clock being faster or slower than Twitters clock. To work out the time ago it takes the timestamp (number of seconds since Unix Epoc) and takes it away from the timestamp at which the tweet was posted. If your servers clock is slower than Twitters, for the first few seconds it ends up giving a negative value therfore seeming as if it was posted in the future. It could be something completely different involving Aliens, badgers and evil pidgeons, but that is the most sensible thing I’ve been able to come up with. If you have a better idea what it is let me know.
Sometimes oAuth Misses The Deny/Accept Page When I Press ‘Sign in with Twitter’?
This happens if you have already authorized Twitter Stream to be used with your Twitter account. Until you press the sign in button the plugin can’t tell if you have already given authorization or not. This generally happens if you have more than one blog using Twitter Stream with the same Twitter account. It’s perfectly normal though.
Can I Style It?
You can. I haven’t added any styles so I could keep the plugin on one file & keep it free of clutter. The available CSS classes are:
a.twitter-linkfor autolinked URL’s within the timeline.
a:hover.twitter-linkfor autolinked URL’s within the timeline when they are hovered over.
a.twitter-datefor the date permalink.
a:hover.twitter-datefor the date permalink when it’s hovered over.
.profile-linkfor the newly added link to user profile.
.follower-countfor the newly added follower count.
Can I Have A Options List?
twitter_stream( [query-string/array] $args);
Here is the info for each parameter.
usernameshould be a string and is the username of the Twitter timeline you want to return. No longer required. If omitted will show the user who authorized Twitter Stream’s timeline.
countshould be a string and is how many tweets to return. Default ’10’.
datebool or string. If set to TRUE it will show the time ago with a hyphen as a default separator. If it is a string of anything other than ‘TRUE’, ‘true’ or ‘1’ it will use that as a separator.
profile_linka string. Allows you to customize what the link to your Twitter profile (shown at the bottom of the tweets) says. ‘Visit My Profile’ by default. Use a space, like this ‘ ‘, to show nothing.
retweetsbool, true or false. Shows retweets with normal tweets.
show_followersbool, true or false. Shows the number of followers.
cache_timeSet the length of time tweets are cached for.
echoControls if the tweets should be echoed out to the page or returned as a SimpleXMLObject for manipulation via PHP. Defaults to TRUE, meaning echo tweets to page.
Here is an example using all parameters.
twitter_stream(array( 'username' => 'twitteruser',
'count' => '10',
'date' => FALSE,
'profile_link' => 'Visit My Profile',
'retweets' => FALSE,
'show_followers' => FALSE,
'cache_time' => 30,
'echo' => TRUE
I Need A Translation!
