I have pages and posts on a WordPress site.

The pages have various layouts. Parent pages are following a 2-column (maincontent + right sidebar) layout while child pages have a one-column layout (no sidebar).

I want to display a JavaScript code on one-column layout, and a different JavaScript code on 2-column layout.

Must also add that one-colum has a custom field "one-col" and 2-column is the default layout. Not sure if it's possible to add codes based on custom fields.

Theme: WooThemes, Canvas.

Really appreciate your help.

function add_js_one_col_wpse_107240() {
  if (is_page()) {
    $pobj = get_queried_object();
    if(!empty(get_post_meta($pobj->ID,'one-col',true)) {
      wp_enqueue_script(/* ... */);
    } else {
       wp_enqueue_script(/* ... a different script ... */);
    }
  }
}
add_action('wp_enqueue_scripts','add_js_one_col_wpse_107240');
  1. get_queried_object will get you the page information. It will be a WP_Post object on a "Page". global $post should probably work too, but this is cleaner.
  2. Use the WP_Post object information to check for the custom meta field. enqueue scripts accordingly. You don't say what the value of one-col is so I checked for any value at all.
  3. Hook the whole thing to wp_enqueue_scripts.

  • +1, as usual, but one sidenote: !empty(get_post_meta($pobj->ID,'one-col',true)) requires PHP 5.5+ while WP's current requirement is 5.2.4

  • @JohannesPille : hmmm... why does that require PHP 5.5? What have I missed? Do I need to save the get_post_meta output to a variable first?

  • Yep. Before 5.5 empty() would only accept variables. Since 5.5 it supports any expression. Hence caching the return of get_post_meta() in a variable before checking for emptiness would support PHP versions below 5.5... (That's my understanding anyhow. Not saying I couldn't be wrong.)
