#31559 new enhancement

Meta boxes should have before/after hooks

Currently there is no way to hook into an existing metabox. If I wanted to modify the featured image metabox (add a checkbox or something), I'd have to unregister the metabox, and re-register w/ my own callback. This is not good for compatibility w/ other plugins, etc.

I propose before_callback and after_callback hooks for metaboxes.

Basically, we'd replace this:

echo '<div class="inside">' . "\n";
call_user_func($box['callback'], $object, $box);
echo "</div>\n";


echo '<div class="inside">' . "\n";

do_action( 'before_metabox_callback', $object, $box );
do_action( "before_{$box['id']}_metabox_callback", $object, $box );

call_user_func($box['callback'], $object, $box);

do_action( 'after_metabox_callback', $object, $box );
do_action( "after_{$box['id']}_metabox_callback", $object, $box );

echo "</div>\n";

I'd rather see this on a case-by-case basis - maintaining something like this into the future seems painful at best.

I'd like to see more extensibility on these features too. Adding extra meta boxes on the same subject seems unorganized and adds unneeded clutter.

A simple filter or a do_action() would be nice.


// Line 763 meta-boxes.php:
<p><strong><?php _e('Order') ?></strong></p>
<p><label class="screen-reader-text" for="menu_order"><?php _e('Order') ?></label><input name="menu_order" type="text" size="4" id="menu_order" value="<?php echo esc_attr($post->menu_order) ?>" /></p>

<?php do_action( 'after_page_attributes_meta_box' ); ?>

<?php if ( 'page' == $post->post_type && get_current_screen()->get_help_tabs() ) { ?>
<p><?php _e( 'Need help? Use the Help tab in the upper right of your screen.' ); ?></p>

A nice scenario would be to add the wpautop filter option to that section through a plugin.
