Thaya Kareeson has written an excellent article for plugin developers. It goes through how to make plugins work with WP Super Cache by using dynamic AJAX calls.
WP Super Cache can make static html copies of pages served by WordPress which is great for performance. Unfortunately that means some plugins don’t work because they rely on executing PHP on each request. The plugins need to be rewritten to use AJAX calls by the visitor’s browser. There’s a FAQ in the readme.txt all about it!
I previously wrote about adding AJAX to WordPress plugins but Thaya has worked through a simple example that will work perfectly with WP Super Cache. It’s a good foundation for plugin developers start from.
- AJAX in Plugins is a must-read starting point for developers.
The vast majority of plugins work just fine with WP Super Cache, but some of the ones that don’t are quite popular. If your favourite plugin doesn’t work, why don’t you help the author out and fix it? You have all the source code after all and you’ll be helping everyone else who uses the plugin!
