I’m trying to add a component I wrote to WordPress as a plugin/widget. I’ve been going through the Codex and so far everything seems pretty straightforward…define the PHP header, define the functions, and then hook them in using add_filter or add_action. I followed the instructions and managed to install and register my basic, functionless widget. At this point, however, the Codex just stops dead.
The actions listed don’t include a awful lot of detail; the parameters are *very* briefly mentioned (what about type? sample data?), return data is often not mentioned at all, and all of the actions/filters link to a blank page (“There is currently no text in this page.”) In some cases, it’s almost impossible to figure out what they’re supposed to do (e.g. function parameter is “array of comment information structures” … what is this? where is it documented?)
Obviously people are writing plugins and widgets, but where are they getting the information to do this? I downloaded a few widgets and tried to look up the actions/filters they hook into and, in about 60% of the cases, the search on WordPress.org returned no results (even a number of the “typical request” actions listed on the Action Reference — http://codex.wordpress.org/Plugin_API/Action_Reference — don’t seem to exist anywhere on WordPress.org).
What am I missing?
Thanks for your help!
