Publish Posts to Multiple Blogs in WordPress Multisite

There are actually two ways of organising shared content between sites in Multisite Network:

  1. Post to multiple sites at once and then synchronising any changes, I will show show in this tutorial how to do it with code or with a plugin.
  2. Indexing content and then having access to it anytime from any site, my another plugin will help you with that.

Using save_post action hook

By the way the code below is similar to the code we used in this tutorial to move network posts from one website to another.

 * Post to Multiple WordPress sites at once
 * @author Misha Rudrastyh
 * @link
add_action( 'save_post', 'misha_post_to_all_sites', 20, 2 );

function misha_post_to_all_sites( $original_post_id, $original_post ){

	// do not publish revisions
	if( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ) {
		return $original_post_id;

	// actually we need only "publish" status
	if( 'publish' !== get_post_status( $original_post ) ) {
		return $original_post_id;

	// prevent "Fatal error: Maximum function nesting level reached"
	remove_action( 'save_post', __FUNCTION__ );

	// here you have to specify blog IDs where you would like to publish the posts
	$blog_ids = array( 2, 3 );

	// let's get this post data as an array
	$post_data = array(
		'post_author' => $original_post->post_author,
		'post_date' => $original_post->post_date,
		'post_modified' => $original_post->post_modified,
		'post_content' => $original_post->post_content,
		'post_title' => $original_post->post_title,
		'post_excerpt' => $original_post->post_excerpt,
		'post_status' => 'publish',
		'post_name' => $original_post->post_name,
		'post_type' => $original_post->post_type,

	// terms and post meta as well
	$post_terms = wp_get_object_terms( $original_post_id, 'category', array( 'fields' => 'slugs' ) );
	$post_meta = get_post_custom( $original_post_id );

	foreach( $blog_ids as $blog_id ) {

		switch_to_blog( $blog_id );

		// if post with the same slug exists, do nothing
		if( get_posts( array( 'name' => $post_data[ 'post_name' ], 'post_type' => $post_data[ 'post_type' ], 'post_status' => 'publish' ) ) ) {

		$inserted_post_id = wp_insert_post( $post_data );

		wp_set_object_terms( $inserted_post_id, $post_terms, 'category', false );
		foreach ( $post_meta as $meta_key => $meta_values) {
			// we do not need these redirects
			if( '_wp_old_slug' === $meta_key ) {
			foreach ( $meta_values as $meta_value ) {
				add_post_meta( $inserted_post_id, $meta_key, $meta_value );


  • Our code shouldn’t duplicate drafts, so I added get_post_status() condition on line 17,
  • Line 22 is critical, otherwise, misha_post_to_all_sites() function will be called inside itself many times as we’re use wp_insert_post() in it. As a result, fatal error: “Maximum function nesting level reached”,
  • You can also see on line 25 that we can post to multiple sites at the same time. You just have to specify blog IDs where you would like to cross-publish posts. If you want to post to all sites, get_sites() function will help you to get all the blog IDs automatically excluding the current one,
  • On lines 42 and 57 you can see that I only use categories here, but you can also add the appropriate code for any terms you’re using within your Multisite Network.

Using my plugin

When I first posted this tutorial I asked in the comment section if any of you guys need a plugin for this. I received a lot of answers “Yes” and the plugin is ready!

It supports custom post types and statuses, custom taxonomies and post thumbnails etc.

Here is how it looks in WordPress editor:
