I don’t know any other way There is a much, much better way to do this – custom fields. As per these instructions in the custom fields docs, let’s say you use the field name iframe_url: <iframe src=”https://wordpress.stackexchange.com/questions/230707/<?php echo esc_url( get_post_meta( $post->ID,”iframe_url’, true ) ?>” width=”960″ height=”540″ frameborder=”0″ allowfullscreen=”allowfullscreen”></iframe> <?php the_content() ?> See how much … Read more
You can conditionally check for a page with is_page so that the woo_custom_order_button_text function only returns for whichever page you specify: // When any single Page is being displayed. is_page(); // When Page 42 (ID) is being displayed. is_page( 42 ); // When the Page with a post_title of “Contact” is being displayed. is_page( ‘Contact’ … Read more
The solution I found so far was to add featured image for categories as a custom field using ACF and then using the category ID to find and display each featured image. Hope it helps anyone 🙂

Each revision stays in the database, however, the way you access it is by going into the post itself and then locating the revision section in the … Read more
You need to declare a location for this data in your class, like an array beforehand and then use it like below: class test { private $first_name; private $data = array(); public function __set($name, $value) { $this->data[$name] = $value; } public function __get($name) { if (array_key_exists($name, $this->data)) return $this->data[$name]; else return ‘not found’; } } … Read more
There are a number of issues with the user of update_user_meta() in your function. First, you should never write the value directly from $_POST without sanitizing it first. That’s a good way to open yourself up to exploits. (Note: you didn’t indicate the field types, so I’m going to assume they are text input – … Read more
Filter should modify the given value and return it. It should not print anything. But your foreach loop does exactly opposite – it prints its output and doesn’t append anything to result. So when you use it to append its result to the content, it prints its result and doesn’t return anything – so nothing … Read more
Maybe there is a way of doing this, but briefly scanning through the relevant functions suggests that I basically have no control over the item being removed, or the call to wc_add_notice to mark is as removed. As such I ended up with the following fairly simple, but slightly ugly method: add_action(‘woocommerce_cart_item_removed’, function($key, $cart){ // … Read more
