You can create a hook by calling do_action, then referring to the hook in your functions.php with add_action. For example, in the theme, where you want the action to occur: do_action(‘woocommerce_before_single_product_intro’); Then in functions.php add_action(‘woocommerce_before_single_product_intro’,’your_function’,[…]); For the sake of maintainability, I’d choose a naming convention that doesn’t confuse your hooks with WooCommerce’s.
That is due to the fact, that your filter woocommerce_breadcrumb doesn’t even exist. This filter here works and pulls out all the elements, that are currently in the breadcrumb (as an array): add_filter( ‘woocommerce_get_breadcrumb’, ‘change_breadcrumb’ ); function change_breadcrumb( $crumbs ) { var_dump( $crumbs ); return $crumbs; } And this filter pulls out the main term … Read more
Currently your code is modifying all term queries, both in the front-end and in the back-end. Each navigational menu is registered as a term in the nav_menu taxonomy, so when you visit the backend to work on the menus, those queries have been modified too by your code snippet. For example, I don’t see any … Read more
I get Undefined variable: for $video, $post_id and $library and the video’s in the page are blank. Replace: add_filter( ‘wp_video_shortcode’, ‘my_video_shortcode’, 10, 2 ); with: add_filter( ‘wp_video_shortcode’, ‘my_video_shortcode’, 10, 5 ); to access all five input arguments in your filter’s callback. ps: my_ is such a common prefix, that I would consider something more unique. … Read more
One way to achieve such effect would be to use wp_nav_menu_objects hook. function modify_home_in_nav_menu_objects( $items, $args ) { foreach ( $items as $k => $object ) { // you can also target given page using this if: // if ( ‘page’ == $object->object && 2 == $object->object_id ) { if ( 30 == $object->ID ) … Read more
There are 3 methods. Somewhat weird but since this text is internationalized you can filter the output. This is just an example to remove the text, the link is still present in the source. add_filter(‘gettext’, ‘remove_powered_by’, 20, 3); function remove_powered_by( $translated_text, $untranslated_text, $domain ) { $custom_field_text=”Proudly powered by %s”; if ( !is_admin() && $untranslated_text === … Read more
Try this: function example_shortcode( $atts ) { $shortcode_output = “<p>Some shortcode content.</p>”; $shortcode_output .= “<p>More shortcode content.</p>”; ob_start(); do_action(‘below_shortcode’); $below_shortcode = ob_get_contents(); ob_end_clean(); $shortcode_output .= $below_shortcode return $shortcode_output; }
The hook is described on this page in Action reference section.
You have the wrong values , you can’t use ← , instead use the right encoding which in that case is ← and also %s for the title. Also you only want this to run on two pages. function back_to_site_text( $translated ) { if ( in_array( $GLOBALS[‘pagenow’], array( ‘wp-login.php’, ‘wp-register.php’ ) ) ) $translated = … Read more
TL;DR: No, you can use save_post. Unless you consider programmatic modification of only metadata “modifying a post”. There (theoretically) is a way of modifying a post without triggering the save_post action hook: Direct modification of the database. But for one no plugin or theme author in his right mind would go that route and for … Read more
