Recently I volunteered to help fix an existing project or develop an OpenID authentication plugin for the vBulletin platform. The group in need was UbuntuForums.org and I would have never known if it hadn’t been for Jorge Castro’s public request for help.
The existing plugin had been developed specifically for vBulletin 3.x, however, they are (as of writing this) in the process of upgrading their forums to vBulletin 4 especially wanted OpenID to be available when they make the upgrade. That’s where I came in.
Canonical, the company behind Ubuntu, provided me with necessary software licenses for vBulletin 4 and from there it was a lot of late nights attempting to simply get a successful OpenID process to occur.
Working a full time job doesn’t make projects like this as easy as I remember them once being… Nonetheless I was able to successful port the plugin to vB4 where there were several significant differences that took me some time to address and to be honest, the previous code was a bit more complicated to follow than it should have been.
One major change from vB3 to vB4 was the way templates work. I’d never worked with vBulletin before, but I’ve had an extensive amount of experience with phpBB and bbPress in the past. After getting over the frustration of how vBulletin prefers to store ALL template information (in the database rather than pull from template files) I was ready to begin the repair process.

This guide walks you through the necessary steps to configure the Eclipse IDE for PHP debugging. This can be very handy, especially when you’re trying to resolve an issue in a complex PHP application or plug-in.
Things you’ll need
- Eclipse PHP Development Tools (PDT)
This article assumes that you are configuring Eclipse and Xdebug for development on a localhost web server. If you are not, be sure to make appropriate adjustments to accommodation your needs. Likely the only changes you will need to make will be differences in connecting to your server verses localhost.
For those that are unaware, Eclipse is a very popular IDE for developing in Java. However, Eclipse is much more powerful than that and can in fact easily be used for developing in many other languages including PHP.
Xdebug is a brilliant debugging extension designed for use with PHP. Once configured, Xdebug will allow you to remotely connect to your web server… or in my case connect to my development localhost web server. Rather than using crude echo and logging techniques to debug your PHP code, Xdebug allows you to literally step through and inspect values and function flows in real-time.

Update: deprecated by phpBB 3.1+
I’ve dealt with spam registrations and spam posts for years now in an online forum that I host. Its a burden on the users and a burden on (especially) the owner. No one wants to use a forum that can’t seem to control spam and no one wants to have a daily routine of manually purging hundreds of posts and users either! That’s where Akismet comes into play. 😉
I’ve used it in combination with WordPress from the beginning and to-date it has blocked nearly 500k spam comments! I enjoy working with web stuff, but I enjoy hacking it together even more.. so I’ve put together a “mod” package that will harness the power of Akismet and its super easy to install! While it won’t take care of spam registrations (you’ll need something else for that), it should be able to dramatically curb spam posts!
What you need
- A web server running at least PHP 5 with phpBB 3 installed (I do not support phpBB2 or lower).
- An Akismet API Key (* Free for personal use, the donation bar DOES drop to $0, though donate if you wish).
- My phpBB + Akismet Installation package
- FTP Access to your phpBB server
- 15-20 minutes for setup time

This is just a little hack I’ve used so I can subscribe to the “Specials” that are periodically released and published on the Steam website.
If you’re interested in letting your Feed client simplify your life by bringing the Steam updates directly to you then I suggest you subscribe to the feed that I’ve setup (via a great free service call Feed For Free).

The Steam News – Announcements feed:
When I searched for a feed for these Specials I came across one forum post after another asking the same thing. We all know how annoying that can be, so to remedy the situation I decided to post a solution myself. 😉
As you can see below, these pages don’t have feeds of their own, but the very awesome Feed For Free site will let you pull the updates straight into your feed reader with ease. See my Google Reader pictured below.
If you’ve for whatever reason noticed that your WordPress website is generating errors similar to the following then I may have a solution for you.
Warning: getimagesize(/home/.some-dir/example.com/folder/httpd.www/wp-content/uploads/some-image.jpg) [function.getimagesize]: failed to open stream: No such file or directory in /home/.some-dir/example.com/folder/httpd.www/wp-content/blah/blah/blah.php on line 123
I noticed that some pages that generated image information were printing errors out on my pages with private server file structures included. Generally you don’t want to see this printed out to the public. 😉
I’m not guaranteeing a fix for you, but rather what worked for me.
If you are getting an error link the one that I’ve listed above, more specifically the “failed to open stream: No such file or directory,” then you may be about to fix it in only a few minor steps.
Things you will need:
- FTP (I use FileZilla)
- Ability to add a new plugin to your site
Single quotes must be the normal ascii quotes. Chances are, if you copy and paste from my blog, they will be the wrong type so double check that as it could give you problems. 😉
- First and foremost, make sure to backup your entire database to a safe place. I’m not liable in the case that you don’t backup your database and this procedure borks your blog (or any other case for that matter). 😉
- Create a new file named “abstest.php” and upload it to your blog’s root directory after entering the following code into it:
<?php define('ABSPATH', dirname(__FILE__).'/'); echo ABSPATH; ?>
- Open a new browser tab and navigate to “http://www.your-website.com/abstest.php“. You should find a short page with the printout of your servers absolute path.
- Check that the path provided by this test file matches the base path printed out by the getimagesize() error exactly. In my case, my server had changed slightly so the differences were similar to the following:
- If you find a mismatch, then you’ve found your problem and the rest is simple. If not, then my tips will most likely not solve your particular WordPress error(s).
- If you’ve found a mismatch, then continue: Open a new browser tab and navigate to your phpMyAdmin interface. Select your WordPress database, then click Search. I searched all tables for a match of the path that was different, in my case it was “.some-dir/“.
- If there are matches found then you need to click the SQL tab at the top (preferably in a new tab) and paste the following (making sure to edit it to match the table and fields you need) and run it to find and replace that changed part of the path.
update TABLE_NAME set FIELD_NAME = replace(FIELD_NAME, ‘find this string’, ‘replace found string with this string’);
For more information on SQL find and replace, either search Google or read this.
- After replacing all of the affected tables and strings, your images should be properly address. You’re not done yet though.
- Open WordPress Plugins and add/install a plugin named “Regenerate Thumbnails“. After installing it, make sure to activate it. 😉
- In your Admin panel, find the Tools menu and expand it. You should see a menu item labeled “Regen. Thumbnails”…click it. This will open a page with a start button. Clicking this button will begin the process of correcting your thumbnail dimensions as well as other metadata. It will take some time depending on the number of thumbnails you have accumulated.
- After the progress bar reaches 100% it will notify you that it is complete. You’re all done! You may need to clear your cache to refresh any pages that still generate the previous error message.
If you had any problems with the above mentioned procedure, I would suggest restoring your database using your backup copy and either trying again, paying someone to do it for you or just forgetting about it. 😉
If it works then great! If not then sorry you’ve wasted your time. It worked for me, so maybe it will work for you as well. 😀
I’ve just pushed a few updates to my WP-UserAgent and WP-TwitterBadge plugins. If you’re already using them then you should be able to update via your WordPress Admin area shortly.
If you’re not using them yet, feel free to browse around and check into them!
I’ve just released an update for the WordPress plugin WP-UserAgent. The update changelog is as follows:
- Added detection for Venenux GNU Linux and Oracle Linux.
- Added detection for Laconica and MovableType trackbacks.
- Cleaned some of the code for trackback detections.
You can find out more about WP-UserAgent as well as a download from the main page.
After weeks of postponing the phpBB 3.0.5 update, I’ve finally gotten around to installing it on my BimmerMania.com forums.
I’ve not been very impressed with phpBB since I first started using in way back when the 2.x branch was the latest stable.
Now that phpBB3 has been bombarded with spam, I’ve been forced to try new anti-spam measures.
I’m very disappointed in their community support for this issue, but I was able to find a great post that covers several options. It’s entitled Preventing Spam in 3.0 and it’s been the best sort of spam solutions I’ve found for phpBB3.
If you’re having problems with spam bots on your phpBB forums, then I would highly suggest that you look into these solutions and pick one that works for you.
In the meantime, I’ll be waiting for phpBB to release some sort of solution to all of this and become as reliable and stable as WordPress has been.
Easy theme and plugin (a.k.a. mod) installs, updates and uninstalls would also be highly appreciated. As well as a one click automatic update system for phpBB itself.
phpBB still has a long way to go before it will be as friendly as the current WordPress admin panel, but all of this manual work isn’t enough to convince me that a better solution is available…so I guess I’ll be sticking with phpBB3 for a while.
After coming across this nifty little Twitter Badge at Techie-Buzz while reading a Google Chrome OS article, I realized how cool their little Twitter link was and I instantly new it was going to be on kyleabaker.com as well. 😀
After a quick look at the source code of the page, I had decided to build a quick plugin for WordPress to insert the same code. So the plugin process began.
I didn’t want to hard code it into the footer of my K2 theme, because I frequently update to the latest K2 theme nightly builds. This way would save me a lot of trouble and even make this neat little Twitter Badge available to thousands. And so…WP-TwitterBadge was born.
I traced the code back to an embeded script from go2web20.net and realized how n00b friendly this script would have been to install anyway even without an easier plugin to install it for you, but the fact that it would save me time in the future was well worth it.
Basically, if you’re not using the WordPress plugin, you just link the script and set a few variables. This made it very easy to make it customizable as well!
Just mimicking their own setup page, I was able to make a quick Options page featuring a live preview (as all of my plugins have so far 😉 ). I even coded the preview with way less script than they used on their own page since extreme error checking is really not needed (everything is live so you can see the problems there).
At a rate of 20-30+ new downloads per hour I would say that this plugin is by far my most favored project…considering that it hasn’t been reviewed yet (no trackbacks thus far) by anyone whereas others already have.
If you’d like to checkout this little Twitter Badge on your own site, just head over to the plugin page or search for “WP-TwitterBadge” from your “Add New Plugins” page in WordPress and install it from there. If you like it, pass it on!
I’ve just updated WP-UserAgent to version 0.8, covering a lot of ground over the past few days. As I’m working to reach a stable and solid 1.0 release, I’m also working towards a feature complete plugin.
Version 0.8 offers support for detecting ~90 different web browsers and ~35 different operating systems (counting each version of windows).
Easy access to WP-UserAgent settings is worked right into the Plugins page. No more need to search for options to edit!
Once you find the options page, you’ll find a cleaned up look and feel, along with a real-time preview of how your changes will appear.
If you’re in need of a cool geeky WordPress plugin, why not give WP-UserAgent a shot? It’s an interesting way to find out a few details about your subscribers and other visitors!
Find out more details, changelogs and downloads on the official WP-UserAgent plugin page.
I just finished (or reached the publishing or pushing live step) the update to the NC State ACM/AITP website.
The improvements over the previous design are pretty drastic when it comes to user interface and ease of use.
I ended up going with a K2 theme for Drupal since I’m such a big fan, but it just didn’t seem right for the site at first. I ended up going through and modifying a great deal of a barely and poorly done version that I came across online so I had to finish up most of it myself, but that just allowed for making it suit my (read ‘our’…for the club) needs.
After working with the html and tweaking it hardcore until I got it clean so it passes HTML Validation inspection it was time to tweak the CSS.
This became a breeze with Opera’s Dragonfly developer tools. I was able to select an element and tweak the style sheet live so I could see real-time results. After making an adjustment it’s as simple as updating the actual stylesheet.
After tweaking the style almost obsessively for hours the first day I decided it was time for a break. It wasn’t long before I got back into the groove the next day and finished it up (for the time being).
I really have to say that I am in love with Dragonfly now. I’ve used Firebug in the past and to be honest I’ve never been a Firefox fanboy…it’s a good browser, but it’s not pushing standards support at the rate that I want and Opera is just better at a lot of the things that I use and need from a browser… anyways, I got used to Firebug a while back and Dragonfly vs. Firebug isn’t a fair competition because the both are still very different, but I find Dragonfly being easier to use ever second compared to Firebug.
After getting the code working it was time to push the update. As a result, the NC State ACM/AITP club now has a much friendlier outlet on the web!
Now I have the pleasure of tackling any smaller issues such as stylesheet problems. 😀 Updating the content will now be much less of a pain now that it can be updated directly from the browser for most everything.
