When can this be the case? Well, of course when is_allowed_cookie(‘_ga’) is false. So either wrap the add_action() call inside that if as … Read more
To fetch the order items you can use the method get_items() I am doing something similar to you and i am doing it like this $order = wc_get_order($order_id); $line_items = $order->get_items(); In WooCommerce 3.0, CRUD objects were added so all the data can be accessed using getters and set using setters.

Just hook your callback into admin_print_styles, i.e.: add_action( ‘admin_print_styles’, ‘mytheme_add_init’ ); Alternately, you could add an is_admin() conditional wrapper inside your callback, and hook into wp_enqueue_scripts: function mytheme_add_init() { if ( is_admin() ) { $file_dir=get_bloginfo(‘template_directory’); wp_enqueue_style(“functions”, $file_dir.”/scripts/custom.css”, false, “1.0”, “all”); wp_enqueue_script(“rm_script”, $file_dir.”/scripts/custom.js”, false, “1.0”); } } add_action( ‘wp_enqueue_scripts’, ‘mytheme_add_init’ ); But the absolute best approach … Read more

JQuery is a part of WordPress core, so it is automatically there for you to use (i.e. you do not need to register it). However, you still need to enqueue it. This can be done as follows: function my_script() { wp_enqueue_script(‘jquery’); } add_action(‘wp_enqueue_scripts’, ‘my_script’); This loads jQuery from WordPress core, the jQuery files can be … Read more
Problem lies in this line: remove_action(‘woocommerce_before_my_account’, array( $this, ‘my_packages’)); This won’t remove action registered by parent class, because $this is a different object in this case, so you won’t remove any action at all. So how to remove such action? Since you can’t access the same $this value in your class, you’ll have to iterate … Read more
Well, since I haven’t used a LIKE in a plugin in a while, it seems I missed this one. WP is now adding ‘placeholders’ whenever you prepare or esc a query. The short solution I found was to do this. It may not be the proper one, but it works. $sql = $wpdb->remove_placeholder_escape($wpdb->prepare(“SELECT ID FROM … Read more
