Load scripts based on post type

Question

Is there a nice way to load a js file based on the post type being viewed?

I have a supplier which has a map on it but I only want the load the js when a single one is being viewed. I load the script in my functions.php file.

Answer 1

If you hook onto a later action such as template_redirect, you should be able to check the query vars to determine if your specific post type is being viewed.

add_action( 'template_redirect', 'example_callback' );

function example_callback() {
    if( is_single() && get_query_var('your-posttype') )
        wp_enqueue_script( .. your args .. );
}

Or alternatively like this...

add_action( 'template_redirect', 'example_callback' );

function example_callback() {
    if( is_single() && get_query_var('post_type') && 'your-type' == get_query_var('post_type') )
        wp_enqueue_script( .. your args .. );
}

Hope that helps.

you can use this code:

add_action('admin_init','load_my_script');
function load_my_script() {
  global $typenow;
  if (empty($typenow) && !empty($_GET['post'])) {
    $post = get_post($_GET['post']);
    $typenow = $post->post_type;
  }
  if (!is_admin() && is_single() && $typenow=='your post type') {
    //load your script here
  }
}
