Restoring deleted posts in WordPress using wp_untrash_post

The wp_untrash_post function in WordPress is utilized to restore a post or page from the trash. When a post or page is deleted in WordPress, it is not immediately removed from the database. Instead, it is moved to the trash, where it can be permanently deleted or restored. The wp_untrash_post function enables the process of restoring these trashed items, effectively moving them out of the trash and back into the list of active posts or pages.

This function operates on the principle of post status within the WordPress database. In WordPress, each post or page has a status that determines its current state, such as ‘publish’, ‘draft’, or ‘trash’. When the wp_untrash_post function is called, it changes the status of the specified post from ‘trash’ back to its previous status, thus ‘untrashing’ it.

It is important to note that the wp_untrash_post function only affects the status of a post within the WordPress database. It does not affect the actual content of the post, nor does it affect any metadata associated with the post. It simply changes the status of the post, allowing it to be visible and editable within the WordPress admin interface once again.

Parameters Accepted by the wp_untrash_post Function

The wp_untrash_post function in WordPress accepts a single parameter. This parameter is:

  • $post_id (integer) – This parameter is optional. It represents the ID of the post. If not specified, the function will use the ID of the global $post by default.

Return Value of the wp_untrash_post Function

The wp_untrash_post function returns a value depending on the success or failure of the operation. The possible return values are:

  • WP_Post – This is the post data that is returned upon successful execution of the function.
  • false or null – These values are returned if the function fails to execute successfully.

if ($result) {
 echo "<p>Post restored from the trash successfully.</p>";

if (get_post_status($post_id) == 'trash') {
 $result = wp_untrash_post($post_id);
 if ($result) {
 echo "<p>Post restored from the trash successfully.</p>";
 } else {
 echo "<p>Failed to restore the post from the trash.</p>";

 if ($result) {
 echo "<p>Post with ID $post_id restored from the trash successfully.</p>";
 } else {
 echo "<p>Failed to restore the post with ID $post_id from the trash.</p>";
