I have managed to create front end post duplication with guidannce from https://toolset.com/forums/topic/front-end-user-duplicate-post-function/. However the values in check boxes and the new relationship linking would not be duplicated, and left blank instead in the duplicated post.

How should I resolve this? Thanks.

Hi there

Checkboxes fields are stored as serialized arrays in wp_postmeta, and I noted an anomaly in how the value is returned by get_post_meta, depending on whether you retrieve the value of the field directly (by specifying the key), where it is returned as an array, or whether you retrieve the value of all fields at once (by not specifying a key), where it is returned as a string.

I updated the code to use the function maybe_unserialize to update the value before saving the post meta on the new, duplicated, post, like so:

function tssupp_duplicate_post( $post_id, $form_data ) {

	if ( $form_data['id'] == 9 ) { // Edit form ID

	    // get data of original post
	    $post = get_post( $form_data['container_id'], ARRAY_A );

	    // update the new post with this data
	    $post['ID'] = $post_id;
	    $post['post_title'] = 'Copy of ' . $post['post_title'];
	    wp_update_post( $post );

	    // get fields of original post
	    $fields = get_post_meta( $form_data['container_id'] );

	    // update the new post with these fields
	    foreach ($fields as $key => $values) {
	        foreach ($values as $value) {   

	        	$value = maybe_unserialize( $value );

	            add_post_meta($post_id, $key, $value, false);
	        }
	    }

	}
}
add_action( 'cred_save_data', 'tssupp_duplicate_post', 10, 2 );

If the posts in question that you are duplicating have related posts created with Types relationships and you want to duplicate the relationships too, then you would need to update the above code to use the relationships API to retrieve the relationship data from the source post and then set up the same on the duplicated post.

You will need to use the functions toolset_get_related_posts to retrieve the relationship data, and toolset_connect_posts to set the same on the duplicate.

These functions are described here: https://toolset.com/documentation/customizing-sites-using-php/post-relationships-api/

The specifics will depend on your relationships, but if you get stuck let me know.
