Hi there,

I have two websites: lien caché and lien caché. I added a Toolset custom field on two.test, a checkbox associated with Posts.

On the homepage of one.test, I want to use the REST API to display all posts on two.test that have the checkbox ticked. I have written nearly all of the code to retrieve posts from two.test and display them on one.test. The only challenging part is retrieving only posts which have their checkbox ticked (the value of the checkbox custom field is "1" when ticked, "" when not ticked).

Can you assist me with this? Here's some of my code to give you a clearer picture:

		$rest_fields = [
			'title',
			'id',
			'link',
			'featured_media', // featured image ID only, not the image path
                       'toolset-meta.post-group.checkbox-custom-field.raw',
		] ;
		$rest_arguments = [
			'_fields'=> implode(',',$rest_fields),
			'per_page' => 20, // maximum number to retrieve
			'orderby' => 'modified', // date modified
			'order'=> 'desc',
		] ;
               $rest_url = add_query_arg ( $rest_arguments, '<em><u>lien caché</u></em>' ) );
		$curl_args = [
			'timeout' => 10,
			'headers' => [ 'Accept' => 'application/json', ]
		] ;
		$response = wp_remote_get ( $rest_url, $curl_args );
		if ( is_wp_error ( $response ) || 200 !== wp_remote_retrieve_response_code( $response ) ) {
			return false ; 
		}
		$response = json_decode(wp_remote_retrieve_body( $response ), true);

Thank you.

Hello. Thank you for contacting the Toolset support.

Have you checked that Toolset offers REST API integration:
- https://toolset.com/documentation/programmer-reference/toolset-integration-with-the-rest-api/

Please check the following related tickets that might help you:
- https://toolset.com/forums/topic/custom-search-and-filter-with-rest-api/
- https://toolset.com/forums/topic/show-and-update-types-checkboxes-in-rest-api/

Maybe you will have to write the rest API endpoint to get the checkboxes values for the checkboxes options.

Checkboxes are stored as serialize array so you will have to manipulate the serialize array for all checkboxes options.
