JacoboPolaviejaHello all,
I'm trying to develop my first plugin, which is just a custom post type with some additional fields and custom taxonomies.
Following codex sample code of 'register_post_type' (http://codex.wordpress.org/Function_Reference/register_post_type) in the "Example" section's code, after registering the post type it puts an "add_filter" function like:
add_filter('post_updated_messages', 'book_updated_messages');
Looking at 'add_filter' function reference, it seems like the first parameter stands for "The name of the filter to hook the $function_to_add to". If don't understand bad, it's a WP hook that when it's called, it will trigger my own function passed as the second parameter.
The problem is I can't find the 'post_updated_messages' hook anywhere in Filter Reference, nor Action Reference.
Even more, when looking at another plugin, I see it calls the 'manage_edit-new_columns' hook through add_filter after registering the new post type. And I can't find that hook neither.
So I assume I may be missing something... and any guidance in this would be great.
Thanks for helping!
