Basic question. There’s a hook I want to alter and I have no idea where to find it. Here’s the code I’m working with. The hook in specific is ‘bp_before_member_header_meta’
”
/**
* BuddyPress - Users Header
*
* @package BuddyPress
* @subpackage bp-default
*/
?>
<?php do_action( 'bp_before_member_header' ); ?>
<div id="item-header-content">
<div class="auther-part">
<div id="item-header-avatar">
<a href="<?php bp_displayed_user_link(); ?>">
<?php bp_displayed_user_avatar( 'type=full' ); ?>
</a>
</div><!-- #item-header-avatar -->
<div class="auther-sidebar">
<div id="item-meta">
<div id="item-buttons">
</div><!-- #item-buttons -->
<?php do_action( 'bp_before_member_header_meta' ); ?>
<?php do_action( 'bp_member_header_actions' ); ?>
There is a global array called $wp_filter that contains the invocations of actions and filters, so if you look in $wp_filter[‘bp_before_member_header’] you will get the current invocations of that action.
You can also use your IDE or grep to look for occurrences of add_action in code. This doesn’t always find them since the names are sometimes built by code. I spent half an hour today looking for an action in Shopp that was built that way.
Edit:
The other side of the action-filter world is found in plugin.php functions do_action and apply_filters. this is the code that actually runs actions and filters, so you can look for calls to this if you want to know where a filter is run. It takes the filter name as an argument and runs all the matching filters in the order specified. It looks like you already know where these are.
If you just want to modify what that particular hook outputs, you should be able to use
add_filter(), and add a filter directly to that hook.
