restrict_manage_posts

.

Now (there’s always more, isn’t there?) is it possible to add a filter for this custom column, I wonder?

You’ll probably need something like this:

add_filter('manage_posts_columns', 'todd_columns');
add_action('manage_posts_custom_column', 'todd_custom_column', 10, 2);

function todd_columns($defaults) {
    $defaults['custom_field'] = ‘My Custom Field’;
    return $defaults;
}

function todd_custom_column($column_name, $post_id) {
    global $wpdb;
    if( $column_name == ‘custom_field’ ) {
	echo get_post_meta($post_id, ‘Ref’, true);
    }
}

The new column is created, but I can’t for the life of me work out how to add the particular data I’d like to put in the new column. And here’s where my almost total lack of coding knowledge is exposed.

What I’d like to add to the column is the data from each Post’s single Custom Field. What code would I need to use to achieve this? (The Key for the custom field is “Ref”, and the Value is an alphanumeric string.)

Any help with this would be appreciated enormously.

Just added it as a link to this page after the short descriptions on the filter and action listing pages.

Thanks!
