WooCommerce-like featured gallery

This is the code i used to achieve my desired result: add_filter( ‘rwmb_meta_boxes’, ‘prefix_register_meta_boxes’ ); function prefix_register_meta_boxes( $meta_boxes ) { $prefix = ‘rw_’; $meta_boxes[] = array( ‘title’ => ‘Media’, ‘pages’ => array( ‘bestilling’), ‘fields’ => … Read more

How to display / include a specific jpg on a page
To load images from the location you currently have them stored use get_site_url() to generate a path: $a = date(‘md’).”.jpg”; $a = get_site_url(null,’images/’.$a); // var_dump($a); Then use that information to create an img tag. I would recommend loading the images from a theme folder, if this is part of a particular theme. If that is … Read more

Example #1 But you can try something like this: /** * Random image size * @return String Image size */ function wpse_random_image_size() { $sizes = (array) get_intermediate_image_sizes(); return $sizes[array_rand( $sizes )]; } to display a random image size. Usage: if ( function_exists( ‘wpse_random_image_size’ ) … Read more
