Why duplicate a WordPress page or duplicate a WordPress post, some may ask.

There are several instances where duplicating a WordPress page or post would be beneficial.

When designing a WordPress website, it is prudent to duplicate the pages of the imported WordPress theme before customizing them.

Or, you have a blog where you want to update old posts by replacing obsolete elements with new content.

Duplicating these old posts before updating them, allows you to keep the post’s featured page image, post metadata, optimized keywords for the post. You will no longer have to manually enter all this information.

It’s also the same for a sales page, or a product page, duplicating them before any addition or update allows you to keep their content and their parameters.

To do this, you have the choice between using an extension or touching the WordPress source code.

This method is the most complex, but it is preferred by some because not installing an additional extension avoids :

  • A potential conflict with other extensions already installed on the site
  • Potential overloading of the site and thus contribute to the fast loading of the site

This method requires you to get your hands dirty.

Indeed, you will have to enter some code in one of the WordPress files to duplicate a page in WordPress or duplicate a post in WordPress.

Enable cloning or duplicating a page and a post within WordPress

Before you can clone or duplicate a WordPress page or post without the use of an extension, you must first enable the cloning feature within WordPress.

To do this, you need a file transfer program like Filezilla to download the WordPress file to be modified, and then once the modification is done, upload the file to the server.

You will also need a code editor to add the activation code to the file.

PS: You should make a backup of your site well before starting this manipulation, just to be safe.

Look for the functions.php file in WordPress and download it.

Using your text editor, add the following code at the end of the file:

/*
 * Function for post duplication. Dups appear as drafts. User is redirected to the edit screen
 */
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!');
  }
  /*
   * Nonce verification
   */
  if ( !isset( $_GET['duplicate_nonce'] ) || !wp_verify_nonce( $_GET['duplicate_nonce'], basename( __FILE__ ) ) )
    return;
  /*
   * get the original post id
   */
  $post_id = (isset($_GET['post']) ? absint( $_GET['post'] ) : absint( $_POST['post'] ) );
  /*
   * and all the original post data then
   */
  $post = get_post( $post_id );
  /*
   * if you don't want current user to be the new post author,
   * then change next couple of lines to this: $new_post_author = $post->post_author;
   */
  $current_user = wp_get_current_user();
  $new_post_author = $current_user->ID;
  /*
   * if post data exists, create the post duplicate
   */
  if (isset( $post ) && $post != null) {
    /*
     * new post data array
     */
    $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
    );
    /*
     * insert the post by wp_insert_post() function
     */
    $new_post_id = wp_insert_post( $args );
    /*
     * get all current post terms ad set them to the new post draft
     */
    $taxonomies = get_object_taxonomies($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);
    }
    /*
     * duplicate all post meta just in two SQL queries
     */
    $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);
    }
    /*
     * finally, redirect to the edit post screen for the new draft
     */
    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' );
/*
 * Add the duplicate link to action list for post_row_actions
 */
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 );

Thanks to this code, you have activated the duplicate of posts, to activate the duplicate of pages, repeat the same code, but replace the last line with :

add_filter('page_row_actions', 'rd_duplicate_post_link', 10, 2);

Save your file with CRTL+S and upload the file to your server.

Now that the cloning feature is enabled, you can duplicate a WordPress page or post.
