As @Even commented, instead of url_to_postid(), you should be using something like this: if ( ! is_single() ) { return; } $post = get_post(); url_to_postid() is a round-about way of getting the ID of the current post, when WordPress has already determined what the current post is, i.e., it has already parsed the URL to … Read more

Hook wp_get_attachment_link for this purpose. Here is an example of how to do it – function attachment_link_filter( $content, $post_id, $size, $permalink ) { // Only do this if we’re getting the file URL if (! $permalink) { // This returns an array of (url, width, height) $image = wp_get_attachment_image_src( $post_id, ‘large’ ); $new_content = … Read more

You are using add_settings_field wrong: the function sl_wp_create_user is being passed as $args (and you probably don’t need any args), and it should be the sanitize callback for register_settings. Make the input like: function sl_render_users_input() { echo ‘<input id=”num_users[value]” name=”num_users[value]” type=”input” value=”” />’; } And the sanitize function: function sl_wp_create_user( $input ) { if( isset( … Read more
