[Plugin: Dave’s WordPress Live Search] Need to emphasize PHP 5 requirement and be less destructive

  • You should emphasize that the plugin requires PHP 5 in the description or at least the installation area. Even if you keep it in the FAQ, please change your code so that sites do not get completely hosed if they install your plugin on 4.x. Everything installs fine, you go to the settings and save, and suddenly your entire site is reduced to a single line on an otherwise blank page: “Dave’s WordPress Live Search requires PHP 5.” Of course, you can’t even get to your WP control panel to deactivate the plugin, so you have to delete the plugin files manually via FTP. Not friendly.

  • Unfortunately, WordPress doesn’t offer a way for plugins to gracefully refuse to turn on. I’ve made some changes to how the plugin behaves under PHP4, and they can be found in the “trunk” (development) version of the plugin. But, the best I can do is nag every time an admin page is displayed.

    If possible, you should seriously consider upgrading to PHP 5. The 4.x versions aren’t being supported anymore, and 5.x offers a ton of enhancements – not the least of which is better performance.
