I had success putting the code below to include enctype (for images) in custom post type forms, but I’m not able to use it in categories form… is this possible?
Thanks.
add_action( 'post_edit_form_tag' , 'post_edit_form_tag' );
function post_edit_form_tag( ) {
echo ' enctype="multipart/form-data"';
}
You’ll need the $taxonomy_term_edit_form_tag action.
