Copy Pages between Sites in Multisite Network

In this tutorial I will show you an easy way to duplicate WordPress pages to any of your sites within a multisite network.

There are different ways to implement that but we going to use WordPress bulk actions.

Copy Pages between Sites within WordPress Multisite network
As an example I decided to use Pages and we do not only copy them, but move between sites. If you need to create duplicates, you will have to change just one line of code.

And of course, if you don’t want to code, I can also recommend an even better solution, it is my plugin developed specifically to copy posts and pages between sites.

The ready code for your theme functions.php:

/**
 * WordPress Multisite: Copy or Move Pages between Sites
 *
 * @author Misha Rudrastyh
 * @link https://rudrastyh.com/wordpress-multisite/move-posts-between-blogs.html
 */
// add bulk actions
add_filter( 'bulk_actions-edit-page', 'rudr_my_bulk_multisite_actions' );
function rudr_my_bulk_multisite_actions( $bulk_array ) {

	$sites = get_sites( array(
		// 'site__in' => array( 1,2,3 )
		'site__not_in' => get_current_blog_id(), // excluding current blog
		'number' => 50,
	) );
	
	if( $sites ) {
		foreach( $sites as $site ) {
			$bulk_array[ 'move_to_' . $site->blog_id ] = 'Move to "' . $site->blogname . '"';
		}
	}

	return $bulk_array;

}

// move or Copy posts 
add_filter( 'handle_bulk_actions-edit-page', 'rudr_bulk_action_multisite_handler', 10, 3 );
function rudr_bulk_action_multisite_handler( $redirect, $doaction, $object_ids ) {

	// we need query args to display correct admin notices
	$redirect = remove_query_arg( array( 'misha_posts_moved', 'misha_blogid' ), $redirect );

 	// our actions begin with "move_to_", so let's check if it is a target action
	if( strpos( $doaction, 'move_to_' ) === 0 ) {
		$blog_id = str_replace( 'move_to_', '', $doaction ); // get blog ID from action name

		foreach ( $object_ids as $post_id ) {

			// get the original post object as an array
			$post = get_post( $post_id, ARRAY_A );
			// if you need to apply terms (more info below the code)
			$post_terms = wp_get_object_terms( $post_id, 'category', array( 'fields' => 'slugs' ) );
			// get all the post meta
			$data = get_post_custom( $post_id );
			// empty ID field, to tell WordPress to create a new post, not update an existing one
			$post[ 'ID' ] = '';

			switch_to_blog( $blog_id );
			
			// insert the post
			$inserted_post_id = wp_insert_post( $post ); // insert the post
			// update post terms
			wp_set_object_terms( $inserted_post_id, $post_terms, 'category', false );
			// add post meta
			foreach ( $data as $key => $values) {
				// if you do not want weird redirects
				if( '_wp_old_slug' === $key ) {
					continue;
				}
				foreach( $values as $value ) {
					add_post_meta( $inserted_post_id, $key, $value );
				}
			}

			restore_current_blog();

			// if you want just to copy pages, comment this line
			wp_delete_post( $post_id );

		}

		$redirect = add_query_arg( array(
			'misha_posts_moved' => count( $object_ids ),
			'misha_blogid' => $blog_id
		), $redirect );

	}

	return $redirect;

}

// show an appropriate notice 
add_action( 'admin_notices', 'rudr_bulk_multisite_notices' );
function rudr_bulk_multisite_notices() {

	if( ! empty( $_REQUEST[ 'misha_posts_moved' ] ) ) {

		// because I want to add blog names to notices
		$blog = get_blog_details( $_REQUEST[ 'misha_blogid' ] );

		// depending on ho much posts were changed, make the message different
		echo '<div class="updated notice is-dismissible"><p>';
		printf(
			_n( 
				'%d post has been moved to "%s".', 
				'%d posts have been moved to "%s".', 
				$_REQUEST[ 'misha_posts_moved' ]
			),
			$_REQUEST[ 'misha_posts_moved' ], 
			$blog->blogname 
		);
		echo '</p></div>';

	}

}

And again, if this code seems difficult, please check my plugin instead.
