Creating a duplicate post or page allows you to work on it without affecting the existing version.
In this article, we will show you how to quickly duplicate a WordPress page or post with all the settings.
Why Clone or Duplicate a Page or Post in WordPress?
When working on a website redesign, you may want to copy and paste the content of an existing page to make tweaks.
While you can edit a page and copy / paste all its content into a new draft, none of the other elements such as featured images, SEO data, page templates, etc would move over.
That’s when having a duplicate page feature in WordPress is really handy.
Similarly for posts, you may need to work on older drafts and published posts on your WordPress site.
You can just edit a post and start working on it. However, this may not be an ideal situation in some cases. For example, some other author may be working on it, or you may want to keep both drafts.
Let’s see how to easily clone a WordPress post or page with just a click.
Besides using plugins, you can also tweak some codes to duplicate WordPress pages and posts. While this method sounds like a bother, it is actually quite simple.
All you need to do is paste the code to your wp-includes\functions.php file.
The code snippet below will enable post duplication in WordPress:
/*
* 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 );
This snippet only works for duplicating posts. You can duplicate WordPress pages by replacing the last line with this code:add_filter('page_row_actions', 'rd_duplicate_post_link', 10, 2);
I hope this tutorial answers all your questions about how to duplicate a post or page in WordPress.
To refresh our minds, let’s have a quick recap:
- First, you can duplicate a page or post using a WordPress plugin. For this purpose, there are three different plugins you can choose: Duplicate Post, Duplicate Page and Post, and Post Duplicator.
- Second, you can do it without a plugin. All you need to do is access the functions.php file in WordPress, then enter the code that we’ve provided.
