How to use post_row_actions filter in WordPress

post_row_actions filter

Filters the array of row action links on the Posts list table.

 apply_filters( 'post_row_actions', string[] $actions, WP_Post $post ) 

Description

The filter is evaluated only for non-hierarchical post types.

This hook is used for generating post row action for custom post type. Also, your Custom Post Type must be non-hierarchical. ‘hierarchical’ => false when declaring your CPT with register_post_type(‘MyCustomPostType’…).

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.

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);

Parameters

• $actions: (string[]) An array of row action links. Defaults are ‘Edit’, ‘Quick Edit’, ‘Restore’, ‘Trash’, ‘Delete Permanently’, ‘Preview’, and ‘View’.
• $post : (WP_Post) Post object.

Live Example

To run the hook, copy the example below.

$actions = apply_filters( 'post_row_actions',$actions, $post ); 
                         
if ( !empty( $actions ) ) { 
                         
   // everything has led up to this point... 
                         
} 
  

The following example is for adding a hook callback.

add_filter( 'post_row_actions', 'modify_list_row_actions', 10, 2 );
 function modify_list_row_actions( $actions, $post ) {
    // Check for your post type.
    if ( $post->post_type == "my_custom_post_type" ) {
         // Build your links URL.
        $url = admin_url( 'admin.php?page=mycpt_page&post=' . $post->ID );
         // Maybe put in some extra arguments based on the post status.
    );
  'copy' ), $url ), 'edit_my_cpt_nonce' );

To remove a hook callback, use the example below.
// remove the filter

 remove_filter( 'post_row_actions', 'filter_post_row_actions', 10, 2 );
