Justin Tadlock recently wrote a great post about making a better functions.php file where (if I remember correctly) he deals with this exact issue. Unfortunately his site is down at the moment so I have to rely on my memory for now. You are on the right track with the after_setup_theme hook. As far as … Read more
You can use the following instead, if (is_singular(‘post’)) { //your code here… } Where by is_singular is the WordPress API conditional function for testing for the existence of a post type. You can also pass an array of post types if you wish. http://codex.wordpress.org/Function_Reference/is_singular
There’s actually a filter that you can use, see abstract-wc-email.php, line 214: return apply_filters( ‘woocommerce_email_recipient_’ . $this->id, $this->recipient, $this->object ); you can put the following in your functions.php: add_filter( ‘woocommerce_email_recipient_customer_completed_order’, ‘your_email_recipient_filter_function’, 10, 2); function your_email_recipient_filter_function($recipient, $object) { $recipient = $recipient . ‘, [email protected]’; return $recipient; } the only drawback is that the recipient will see … Read more
The problem is that you can’t distinguish form an anonymous function and another, so yes, it is possible to remove a closure (i.e. anonymous function) but if more than one closure act on same filter at same priority you have to make a choice, remove them all, ore remove only one (without knowing exactly which). … Read more
This is what I have used to create a custom order status called “Invoiced”. Add this to your theme’s functions.php // New order status AFTER woo 2.2 add_action( ‘init’, ‘register_my_new_order_statuses’ ); function register_my_new_order_statuses() { register_post_status( ‘wc-invoiced’, array( ‘label’ => _x( ‘Invoiced’, ‘Order status’, ‘woocommerce’ ), ‘public’ => true, ‘exclude_from_search’ => false, ‘show_in_admin_all_list’ => true, ‘show_in_admin_status_list’ … Read more
This has always been a bugbear for me – the lack of on-demand image sizing, and the subsequent number of files you can end up with if you have lots of sizes! I can see the logic behind your efforts – the trouble is, add_image_size only truly comes into play at point-of-upload. As such, is_page_template(..) … Read more
The hook you’re looking for is specifically wp_head which could look something like this: function theme_xyz_header_metadata() { // Post object if needed // global $post; // Page conditional if needed // if( is_page() ){} ?> <meta name=”abc” content=”xyz” /> <?php } add_action( ‘wp_head’, ‘theme_xyz_header_metadata’ ); I believe in the long run though, since WordPress is … Read more
functions.php is processed way before you can know which page is being loaded. Instead of assigning value to variable put your code into function and use that function in page.php template.
Use this function: function user_id_exists($user){ global $wpdb; $count = $wpdb->get_var($wpdb->prepare(“SELECT COUNT(*) FROM $wpdb->users WHERE ID = %d”, $user)); if($count == 1){ return true; }else{ return false; } } Usage: if(user_id_exists(1)){ //it does exists } else { //it doesn’t }
You can also use $post_id = $_GET[‘post’]; Or you can use a hook (probably better). function id_WPSE_114111() { global $post; $id = $post->ID; // do something } add_action( ‘admin_notices’, ‘id_WPSE_114111’ ); You will need to add a conditional since this will run on all admin pages, I recommend using get_current_screen(); For example to run only … Read more
