Don’t put your variables in single quotes. This: if(isset($submit)){ $args = array( ‘numberposts’ => 10, ‘meta_key’ => ‘$filter’, ‘orderby’ => ‘meta_value’, ‘order’ => ‘DESC’, ‘post_type’ => ‘things’, ‘post_status’ => ‘publish’ ); $mystuff = get_posts( $args ); $name = $filter ; } Should be this: if(isset($submit)){ $args = array( ‘numberposts’ => 10, ‘meta_key’ => $filter, ‘orderby’ … Read more

The documentation is well explicable of the topic, let’s have a look here https://developer.wordpress.org/reference/functions/apply_filters/. In your specific case my_filter is applied no matter what, even if there is no value it.

Creating variables on the fly like that is not needed. Just use an array instead. $myvars = []; inside your foreach loop you can: $myvars[] = array(‘title’=>$t,’image’=>$v); After your loop you can: //First title, First image echo $myvars[0][‘title’]; echo $myvars[0][‘image’]; //Second title, Second image echo $myvars[1][‘title’]; echo $myvars[1][‘image’]; This way you can always print_r($myvars) and … Read more
