$post=get_post($post_ID); 
$old_name=$post->post_name; 
$my_post = array(
'ID'   => $post_ID, 
'name' => $old_name."--".rand(1111,9999), 
); 
wp_update_post($my_post); 

return $post_ID; 
} 
add_filter('add_attachment', 'update_attachment', 10, 2); 

Answer 1

請試試這個

function update_attachment($post_ID) { 
    $post=get_post($post_ID); 
    $old_name=$post->post_name; 
    global$wpdb; 
    $wpdb->query("update ".$wpdb->prefix."posts set post_name='".$old_name."-".rand(1111,9999)."' where ID='".$post_ID."'"); 
    //var_dump($post_ID); exit; 
    return $post_ID; 
} 

add_filter('add_attachment', 'update_attachment', 10, 2);
