[updated 21. dec 2011, see code change]

I had the need to alter the OpenCart ( order confirmation eMail to include some legal text (german Impressum (company contact) and Wiederrufsbelehrung, Stichwort Abmahnung) and to remove the display of the IP.

WordPress Plugin to feed CodeProject Technical Blogs


Update 3. sept. 2011:
Fixed a bug according to WeBiscuit’s post at the CodeProject Technical Blog Article. See download of version 1.11.

In the beginning, everything was done manually.

After the third time I had to edit feed-rss2.php of wordpress to fulfill CodeProjects Technical Blogs requirements I now wrote my first (and last?) wordpress plugin.

As you may know, CodeProject allows you to publish articles through your current blog. See here for the FAQ.

As I am using wordpress, I started some time ago to submit blog entries into CodeProject. I had to find out myself, where to change which file.

Limit published articles

To limit the range of blog entries that are published at CodeProject Technical Blogs I use a ‘hidden’ feature and created a category named ‘CodeProject’ in my WordPress blog. On my Technical Blogs site in CodeProject I then used for the feed input. Now only the articles marked with WordPress category ‘codepoject’ are feed to CodeProject.

Manually changes required in WordPress for CodeProject Technical Blogs

In feed-rss2.php I always had to add a <category>CodeProject</category> line below <channel>. Further I had to change the footer.php of the wordpress theme Win7blog that I use. There I added a rel=”tag” line as recommended by CodeProject.

The pain of doing it again and again

Now, the first manual change has to be done everytime you update your wordpress release. I had to to this at least three times before I start now with a plugin to I avoid changing the file again manually.

The idea of a WordPress plugin

I never wrote a WordPress plugin before, but I did some html, php and mysql coding before (ie the calendar on or the static pages at, which are generated from a db). But the learning curve was hard and it took me several hours to get the plugin working. I started with the plugin described at DevLounge in there “How to write a WordPress plugin” series. The article was the only one I could find that describes wordpress plugin development from scratch with a working example.

As I had problems adopting the code to my needs, especially the AdminPage, I had to rewrite the code a little bit.
