post_row_actions for custom post type

Question

I'm using this code to have a duplicate post function in WordPress Admin. However, when I add the filter for a custom post type, like this:

add_filter( 'directory_row_actions', 'rd_duplicate_post_link', 10, 2 );

(The Custom Post Type has a registered name of directory) - it doesn't add it to the action row underneath the entry title. When I do it for the posts or pages, like this:

add_filter( 'post_row_actions', 'rd_duplicate_post_link', 10, 2 );

it works perfectly. I've been reading that post_row_actions has been deprecated but I can't find anywhere that says it's replacement. Does anyone know how to get this working for my Custom Post Type?

Answer 1

As @bonger commented, there is no custom post type filter despite what you've read.

To use this filter for a specific post type, the best way is to use the post_row_actions filter and then test against the passed in $post->post_type.

I've used the code below to add links to the actions row for a specific post type (in this case, myposttype).

This will need to be edited to work for your own post type, and obviously for the new link to actually do anything more code is needed, but this is the idea:

function my_duplicate_post_link($actions, $post)
{
    if ($post->post_type=='myposttype')
    {
        $actions['duplicate'] = '<a href="#" title="" rel="permalink">Duplicate</a>';
    }
    return $actions;
}
add_filter('post_row_actions', 'my_duplicate_post_link', 10, 2);

//Post, page or all register custom post types

function im_duplicate_post_link($actions, $post)
{
    // get all post type which is register
    $posttypes = get_post_types(array('public' => true), 'names', 'and');
    foreach ($posttypes as $post_type)
    {
        $posttype[] = $post_type;
    }
    //check current post type is in "$posttype"  array, if it's in array then display duplicate link.
    if (in_array($post->post_type, $posttype))
    {
        $actions['duplicate'] = '<a href="admin.php?action=im_duplicate_post_as_draft&amp;post=' . $post->ID . '" title="Duplicate this item" rel="permalink">Duplicate</a>';
    }
    return $actions;
}
// this hook for post and custom post type
add_filter('post_row_actions', 'im_duplicate_post_link', 10, 2);
// this hook for page
add_filter('page_row_actions', 'im_duplicate_post_link', 10, 2);
