Updated Answer — @Quasimodo confirmed that they’re only interested in posts of the page type and that the numeric slugs are four-digit years, e.g. 2019. What can I do to allow numeric slugs for child pages? I would use the pre_wp_unique_post_slug hook that runs prior to wp_unique_post_slug, which means we’ll be filtering the slug before … Read more
I imagine you’re also adding a filter mce_buttons to add in the button to, something like.. add_filter( ‘mce_buttons’, ‘add_my_tinymce_buttons’ ); function add_my_tinymce_buttons( $items ) { $items[] = ‘your-button’; return $items; } Just change the filter to hook onto mce_buttons_2 instead, and the button will appear on the second row , eg.. add_filter( ‘mce_buttons_2’, ‘add_my_tinymce_buttons’ ); … Read more
By default add_filter() instructs WP to only pass first parameter to your hooked function. If you want more you need to specify that (and priority which comes earlier and defaults to 10): add_filter( ‘get_bookmarks’, ‘samiconductor_sort_links_by_order’, 10, 2 );
You can always use GitHub. WordPress has an official (view-only) GitHub repository, and GitHub has an excellent comparison feature. Here’s the GitHub comparison of WordPress 3.4.2 vs 3.5.

I do not know if this is intentional behavior so caveat emptor, but it is very useful behavior. Simply send your … Read more
There are no specific searches for WooCommerce. It utilizes WordPress default search system. By default WordPress does not search within tags ( not sure if that has changed for WP 3.6 ). It searches only in titles and description. This is the same if it is for a product.
After some Googling, I found a solution that was originally done for a Twitter embed, but I modified it to work with all oEmbed contents. Keep in mind that for this to work on existing posts, you’ll need to do an “update” for the oEmbed content to refresh from the cache. add_filter(‘oembed_result’,’center_oembed’,10,3); function center_oembed($html, $url, … Read more
Make sure you remove the action after the theme has added it. And use the same priority. A rather safe way is using the same action you want to clean up: add_action( ‘admin_notices’, ‘remove_woothemes_updater_notice’, 0 ); function remove_woothemes_updater_notice() { remove_action( ‘admin_notices’, ‘woothemes_updater_notice’ ); }
For every filter or action hook that you use with the add_filter or add_action functions, there is a corresponding apply_filters or do_action function called somewhere in the WordPress core.
