I've got a plugin that attaches itself to both the post and page editors to read and write to the post_content object. I'd like to also attach my plugin to the category manager edit screen.

In the code below, lines 1 and 2 attach it to the post and page editor, but line 3, a shot in the dark, is not yet doing the trick. Any ideas on the proper way to do it?

if ( function_exists('add_meta_box') ) { 
    add_meta_box('My-plugin', __('My plugin'), 'My_plugin_callback', 'post', 'side', 'high');
    add_meta_box('My-plugin', __('My plugin'), 'My_plugin_callback', 'page', 'side', 'high'); 
//???   add_meta_box('My-plugin', __('My plugin'), 'My_plugin_callback', 'category', 'side', 'high');
}

I'm pretty sure that even if you add that meta box at the bottom of the category edit you will still have the problem of meta table for categories, and i bet that your meta_box 'save' function saves as postmeta data table.

However this can be done using the options table here is an how to add extra fields to categories

Hope this helps

@בניית אתרים: Thanks. I've already got a few extra fields on my category edit screen using the "edit_category_form" add_filter. I'm just trying to see if there's an add_meta_box hook on that screen to make this as simple as it was to add the interface to the post and page editors. –  Scott B Feb 15 '11 at 17:06

@Scott B: I'm afraid it's not that simple but its not that hard either, if you already have a extra fields then create a new function based on your meta-box display function, and change it a bit to display on the category edit form using 'edit_category_form' filter and create another function based on your meta-box save function and change it a bit to save on the category extra fields instead of postmeta and hook that to 'edited_category' filter –  Bainternet Feb 15 '11 at 17:31
    
That sounds like a plan. Let me work on it and see what I can come up with. Thanks for taking time to explain that. –  Scott B Feb 15 '11 at 21:27
    
+1 for best answer considering there the answer to the original question appears to be "No" :-) –  Scott B Feb 19 '11 at 15:37
