Move All WordPress Posts To Trash

If you need to move all WordPress posts to trash, you can use a custom function and the wp_trash_post function to do so. In this post, we’ll walk through the steps to create a function that loops through all posts and then trashes all posts. And then hook it to an action so that it executes when needed. This is a quick and easy way to clear out old posts.

1. Create a custom function that retrieves all posts and trashes them using the wp_trash_post function:

function trash_all_posts() {
$posts = get_posts(array(
'numberposts' => -1,
'post_status' => 'any',
'post_type' => 'post'
));
foreach($posts as $post) {
wp_trash_post($post->ID);
}
}


2. Hook the function to an action. For example, you can hook it to the wp_footer action:

add_action('wp_footer', 'trash_all_posts');


This will execute the trash_all_posts function whenever the wp_footer action is triggered.

Keep in mind that trashing a WordPress post moves it to the trash bin, but it doesn’t delete it permanently. To delete the posts permanently, you’ll need to use the wp_delete_post function instead. For more library functions you can refer to wp codex. 

Whether you’re cleaning up your site or preparing for a redesign, this technique can save you time and effort.
