To remove an action or filter, the function/method name and the priority must match with the previously added action/filter. The action you want to remove is added with a priority of 10 (default value) while you are trying to remove the action with priority of 99. Try this: remove_action( ‘woocommerce_product_options_inventory_product_data’, array( ‘Electro_WC_Helper’, ‘product_options_inventory_product_data’ ) ); … Read more
This is a bug in the theme. The real function does indeed not use the parameter: /** * Display the post excerpt. * * @since 0.71 * @uses apply_filters() Calls ‘the_excerpt’ hook on post excerpt. */ function the_excerpt() { echo apply_filters(‘the_excerpt’, get_the_excerpt()); } PHP will just ignore it, but the unnecessary gettext call should be … Read more
I think the plugin you mention is the one I wrote so if you’re looking for answer on how to do it take a look at the code. http://wordpress.org/extend/plugins/dropdown-menus/ Essentially all I did was create a custom menu walker class so I could output the menus created in the backend as a dropdown. If it … Read more
If the theme is a relatively modern one, find this line of code in the functions.php file and remove it: add_theme_support( ‘automatic-feed-links’ ); If it’s an older theme, then look in the header.php file for the code that adds those.
You can filter the default gallery shortcode. Here is something I’ve used in the past. add_filter( ‘post_gallery’, ‘wpse_gallery’, 10, 2 ); function wpse_gallery() { global $post; /* Orderby */ if ( isset( $attr[‘orderby’] ) ) : $attr[‘orderby’] = sanitize_sql_orderby( $attr[‘orderby’] ); if ( !$attr[‘orderby’] ) unset( $attr[‘orderby’] ); endif; /* * Extract default gallery settings … Read more
You can Detect Server Remote Address and if it matches with your IP then you can use different theme following way. function wp_set_preview_theme( $current_theme ) { if ( ‘YOUR_IP_ADDRESS’ === $_SERVER[‘REMOTE_ADDR’] ){ // Use your preview theme instead return ‘THEME_YOU_WANT_TO_USE’; } else { // Otherwise, keep the current theme return $current_theme; } } add_filter( ‘stylesheet’, … Read more

The GPL merely allows the end user, whether he received the GPL-licensed code for free or for cost, to use the code however he likes, to redistribute the code, to modify the … Read more
If you mean the default WordPress Widgets, you would add this to the functions.php file: <?php // unregister all default WP Widgets function unregister_default_wp_widgets() { unregister_widget(‘WP_Widget_Pages’); unregister_widget(‘WP_Widget_Calendar’); unregister_widget(‘WP_Widget_Archives’); unregister_widget(‘WP_Widget_Links’); unregister_widget(‘WP_Widget_Meta’); unregister_widget(‘WP_Widget_Search’); unregister_widget(‘WP_Widget_Text’); unregister_widget(‘WP_Widget_Categories’); unregister_widget(‘WP_Widget_Recent_Posts’); unregister_widget(‘WP_Widget_Recent_Comments’); unregister_widget(‘WP_Widget_RSS’); unregister_widget(‘WP_Widget_Tag_Cloud’); unregister_widget(‘WP_Nav_Menu_Widget’); } add_action(‘widgets_init’, ‘unregister_default_wp_widgets’, 1); ?> EDIT: register_sidebar(array(‘name’=>’sidebar2’, ‘before_widget’ => ‘<ul><li>’, ‘after_widget’ => “</li></ul>”, ‘before_title’ => ‘<h2 class=”widgettitle”>’, … Read more
If you look at how the code works, you should notice that theme mods are saved in the *_options table under theme_mods_{theme_slug} with the theme slug being, as near as I can tell, the directory name containing the theme stylesheet, so: $ptheme = get_template_directory(); $theme_slug = basename($ptheme); $mods = get_option( “theme_mods_$theme_slug”); As a function: function … Read more
Drop this inside a .php file in in wp-content/mu-plugins: add_filter(‘template’, ‘check_for_theme_preview’); add_filter(‘stylesheet’, ‘check_for_theme_preview’); // if you want to display the theme selector // (this is wrong, you need a custom action in each of your themes, after <body>) add_action(‘wp_head’, ‘display_template_selector’); // checks for the “theme-preview” argument, and changes the template function check_for_theme_preview($template){ session_start(); if(isset($_SESSION[‘template’])) $template … Read more
