The first step is the rewrite rule. I’ve also added a rewrite tag so the custom query var will be parsed. You can also use the query_vars filter for this instead. add_action( ‘init’, ‘tipp_rewrite_rule’ ); function tipp_rewrite_rule() { add_rewrite_tag( ‘%trick_nummer%’, ‘([a-zA-Z0-9]+)’ ); add_rewrite_rule( ‘^tipp([a-zA-Z0-9]+)?’, ‘index.php?trick_nummer=$matches[1]’, ‘top’ ); } The second step is to intercept these … Read more
The problem was a redirect in site-info.php. After that the $_POST variable was empty in the code inserting in the admin_footer. I just need to use a further hook ‘admin_init’ and save the value here. add_action(‘admin_init’, ‘pg_save_custom_site_options’); function pg_save_custom_site_options(){ global $pagenow; if( ‘site-info.php’ == $pagenow && isset($_REQUEST[‘action’]) && ‘update-site’ == $_REQUEST[‘action’] ) { // Use … Read more
I managed to figure it out myself reading around, solved it with this: <div id=”grid”> <?php $args = array( ‘depth’ => 0, ‘child_of’ => 411 ); $pages = get_pages(array(‘child_of’)); $grid_title = $post->post_title; foreach($pages as $post) { setup_postdata($post); $fields = get_fields();?> <?php if($fields->company_name != “”) : ?> <!– Any new tags will need to be added … Read more
in_category relies on a global post – it should only be used within the loop. Instead, use the arguments that are passed to your callback to query the categories assigned to the post being edited and check if one of them is video: $cats = get_the_category( $post[‘ID’] ); if ( in_array( ‘video’, wp_list_pluck( $cats, ‘slug’ … Read more
To see how such a list can be created look at the code in wp-admin/includes/nav-menu.php. Unfortunately, it is hard coded there, so you have to re-create the code. First, let’s create two menus: We can get these menus in PHP with wp_get_nav_menus() (a wrapper for get_terms()): $menus = wp_get_nav_menus(); print ‘<pre>’ . htmlspecialchars( print_r( $menus, … Read more
Try this to loop through up to 4 slides – checking each for a valid slide: <?php $max_slides = 4; // this should be the maximum number of slides there can be for ($i=1; $i<=$max_slides; $i++) { // check for slide $key = ‘slide’ . $i; $slide = get_post_meta($post->ID, $key, $single = true); // check … Read more
You can do this with an action when a new product is inserted (and not when updated). As you did not specify the meta key this field is stored under the user as, OR the meta key of where you want it stored on the product: add_action( ‘wp_insert_post’, ‘smyles_insert_user_product_data’, 10, 3 ); function smyles_insert_user_product_data( $post_ID, … Read more
Prefixing custom fields with an underscore only results in the keys being hidden from the default custom fields UI: There is nothing preventing plugins or theme code from otherwise querying these keys and their values.
get_col() function returns only one column as array. To get two column result we can use get_results(), Which will return an array of objects Which further can be converted into required structure using foreach loop. Example – function get_meta_values( $key = ”, $type=”post”, $status=”publish” ) { global $wpdb; if( empty( $key ) ) return; $r … Read more
