Relative paths can be confusing in complex applications like WordPress. Plugin files themselves are included by the scripts that call them, and so relative locations within will be interpreted as those of the file that called them. It’s always best practice to provide a full path using a magic constant such as __FILE__ or __DIR__, … Read more
You’ve given wp_enqueue_style a directory, but no file name. Have a look at https://developer.wordpress.org/reference/functions/wp_enqueue_style/: The first parameter of wp_enqueue_style is the name, or handle, of the stylesheet as referred to internally by WordPress (this should be a unique name for each stylesheet you enqueue) The second parameter is the src to the stylesheet – so … Read more
You have to load text domain in your plugin: <?php function my_load_textdomain() { load_plugin_textdomain( ‘add-to-post-footer’, // text domain identifier false, // deprecated parameter plugin_basename(dirname( __FILE__ )) . ‘/languages’ ); // path to the languages directory } add_action(‘plugins_loaded’, ‘my_load_textdomain’);
Yes and no, WP_Query fetches posts, it doesn’t display them. You can query for WooCommerce products as they’re a custom post type. Just create a query object, and specify the post_type parameter to use the post type WooCommerce uses, then loop over them, displaying them and grabbing the post meta such as the SKU as … Read more
Add a post meta field to indicate this post is just a redirect when creating it: $postid = wp_insert_post($newpost); add_post_meta($postid,’redirect’,’1′); Check the post meta value and if it is a “redirect post”, just output the post content (javascript redirect): add_action(‘wp’,’custom_maybe_redirect’); function custom_maybe_redirect(); global $post; if (!is_object($post)) {return;} $redirect = get_post_meta($post->ID,’redirect’,true); if ($redirect == ‘1’) {echo … Read more

In the context of official plugin repository this is very explicitly forbidden by the guidelines (emphasis mine): 7. No “phoning home” without user’s informed consent. This seemingly simple rule actually covers several different aspects: No unauthorized collection of user data. For example, sending the admin’s email address back to your own servers without permission of … Read more
Given that you want to include a picture in the wp_nav_menu output, your best bet is to use the wp_nav_menu_items filter, as suggested in the comments. This will allow you to do a search and replace on the html. add_filter (‘wp_nav_menu_items’,’wpse229358_filter_menu’); function wpse229358_filter_menu ($items,$args) { $search=””; // html string of button $replace=””; // html string … Read more
You can add stylesheet in back-office, but you need for that use the admin_enqueue_scripts action. See Codex reference : https://codex.wordpress.org/Plugin_API/Action_Reference/admin_enqueue_scripts
Sure. In your single.php or where you loop through the posts, start by getting the content: $content = get_the_content(); Then use a regex where you target anything within <h2> tags: $regex = ‘/<h2>(.*?)\<\/h2>/u’; And then use preg_match_all() to find all titles: preg_match_all($regex, $content, $table_of_content); This will create a multidimensional array, see: print_r($table_of_content); So you have … Read more
