Thank for writing about this topic. That is what is so great about having a WordPress website… the great plugins and people like you who are willing to share there experience with the rest of the community. I have to set aside some time to write a custom Wordpress plugin for my website and give it bask to the community. Thanks again for the great post.

Safia, In the case of extending the data I would recommend adding it to a new table in the same WP database. Assuming its all going to be managed and and displayed within WordPress you’re in good shape to handle it like that. I personally wrote a plugin for my church’s website that uses the WP database, but has several tables to manage recordings and schedules of the series, teachers, files, and lessons. I hope that helps!

What if you need a plugin to access data that is not ordinarily a part of the wordpress database…. should you extend the data base or create a new one? I am creating a webpage for a school and I want a plugin to display the current courses being offered by a specific department.

[...] Randy Peterman – Although a little outdated(it relates to WP1.2), the second part of this plugin tutorial details all the ways of interacting with the database, which is really useful if your plugin allows users to define how your plugin behaves, and you need to call that information in other parts of your plugin.

Wow, PJ. That’s like saying there’s no need for modern translations of Homer because between the ancient greek transcriptions and a English-to-Ancient-Greek dictionary, his epics are fully described.

Randy, as a non-programmer and a new user of WP, this entry (two years old!!) helped me a lot as I wrote a couple important plug-ins for my site. I’m sure glad PJ didn’t act on your clever response. Thanks!

Fair enough. I didn’t add them into the wiki. But since it is a wiki, you can remove them if you’d like.

IMHO, I don’t think these blog post links should be in the codex. There’s no info here that’s not already on the WordPress website.

[...] Hello Dolly is WordPress’ first plugin. The commented source for that plugin might help you understand how plugins work and act as a guideline for the structure and syntax to use in writing your own plugins. There is also an introductory article (http://www.randypeterman.com/wordpress/index.php?p=597) Part II (http://www.randypeterman.com/wordpress/index.php?p=648) that may prove useful. A simple explanation of the database tables can be found on the Database Description page. [...]

Wow…as a noobie to WP and PHP but nonetheless a programmer, I have begun “mucking about” in the code and wondered what all of these calls did (no, I still have not gotten my PHP book yet – darn it). Thanks for the great explanation. I hope to see some more – maybe even a series. ;)

Great going!
Just a note, about the table names. In 1.3 (upcoming) and later, the table names will be of a different form, for example “$wpdb->posts” will replace $tableposts and so on.
I will look forward to III, if there is one :)
