Duplicate Pages & Posts without WordPress Plugins

Duplicate Pages & Posts without PluginsAn experienced WordPress Developer will tell you that a website today should have a minimal amount of plugins if any at all.

Benefits of using a limited number of plugins include:

  • Improved website security
  • Fewer plugin updates to maintain
  • Less third-party code to rely on
  • Faster loading website content

I recently learned how to duplicate posts without a plugin by accident…

But what about pages?

Obviously, that would be beneficial too, right?

So, I added the last line of code to duplicate pages in addition to posts.

And since I have been using plugins like Duplicate Pages for some time now, I wanted to give this code snippet a test run.

After seeing it work without issue, I had to share it with you.

See below the exact code to add to your functions.php file that will allow you to duplicate pages AND posts without the need of a plugin.

/* BEGIN BY JL: Duplicate Post & Pages */

function rd_duplicate_post_as_draft(){
	global $wpdb;
	if (! ( isset( $_GET['post']) || isset( $_POST['post'])  || ( isset($_REQUEST['action']) && 'rd_duplicate_post_as_draft' == $_REQUEST['action'] ) ) ) {
		wp_die('No post to duplicate has been supplied!');
	}

	if ( !isset( $_GET['duplicate_nonce'] ) || !wp_verify_nonce( $_GET['duplicate_nonce'], basename( __FILE__ ) ) )
		return;

	$post_id = (isset($_GET['post']) ? absint( $_GET['post'] ) : absint( $_POST['post'] ) );

	$post = get_post( $post_id );

	$current_user = wp_get_current_user();
	$new_post_author = $current_user->ID;

	if (isset( $post ) && $post != null) {

		$args = array(
			'comment_status' => $post->comment_status,
			'ping_status'    => $post->ping_status,
			'post_author'    => $new_post_author,
			'post_content'   => $post->post_content,
			'post_excerpt'   => $post->post_excerpt,
			'post_name'      => $post->post_name,
			'post_parent'    => $post->post_parent,
			'post_password'  => $post->post_password,
			'post_status'    => 'draft',
			'post_title'     => $post->post_title,
			'post_type'      => $post->post_type,
			'to_ping'        => $post->to_ping,
			'menu_order'     => $post->menu_order
		);

		$new_post_id = wp_insert_post( $args );

		$taxonomies = get_object_taxonomies($post->post_type); // returns array of taxonomy names for post type, ex array("category", "post_tag");
		foreach ($taxonomies as $taxonomy) {
			$post_terms = wp_get_object_terms($post_id, $taxonomy, array('fields' => 'slugs'));
			wp_set_object_terms($new_post_id, $post_terms, $taxonomy, false);
		}

		$post_meta_infos = $wpdb->get_results("SELECT meta_key, meta_value FROM $wpdb->postmeta WHERE post_id=$post_id");
		if (count($post_meta_infos)!=0) {
			$sql_query = "INSERT INTO $wpdb->postmeta (post_id, meta_key, meta_value) ";
			foreach ($post_meta_infos as $meta_info) {
				$meta_key = $meta_info->meta_key;
				if( $meta_key == '_wp_old_slug' ) continue;
				$meta_value = addslashes($meta_info->meta_value);
				$sql_query_sel[]= "SELECT $new_post_id, '$meta_key', '$meta_value'";
			}
			$sql_query.= implode(" UNION ALL ", $sql_query_sel);
			$wpdb->query($sql_query);
		}

		wp_redirect( admin_url( 'post.php?action=edit&post=' . $new_post_id ) );
		exit;
	} else {
		wp_die('Post creation failed, could not find original post: ' . $post_id);
	}
}
add_action( 'admin_action_rd_duplicate_post_as_draft', 'rd_duplicate_post_as_draft' );

function rd_duplicate_post_link( $actions, $post ) {
	if (current_user_can('edit_posts')) {
		$actions['duplicate'] = '<a href="' . wp_nonce_url('admin.php?action=rd_duplicate_post_as_draft&post=' . $post->ID, basename(__FILE__), 'duplicate_nonce' ) . '" title="Duplicate this item" rel="permalink">Duplicate</a>';
	}
	return $actions;
}
 
add_filter( 'post_row_actions', 'rd_duplicate_post_link', 10, 2 );
add_filter( 'page_row_actions', 'rd_duplicate_post_link', 10, 2 );

/* END BY JL: Duplicate Post & Pages */

Want to hear something ironic?

The same day I created this post, another vulnerability was found in the Duplicate Page plugin as described here.

Be safe out there!
