If you are programmatically adding posts to WordPress and using FacetWP, when you add a new post you must force FacetWP to re-index.
If a post is added in the admin, FacetWP does this for you. However if you add posts with code, you need to fire a re-index.
You can do this with the code below.
This example, re-indexes a specific post, the new post ID is taken from the post just created.
In this example, my function (hd_reset_job_facets) is hooked into a action that fires after our post is created.
You would need to hook into whatever hook is appropriate that runs once your post is added.
<?php
/**
* Re-indexes FacetWP when a new job arrives.
*
* @param integer $job_post_id The newly created job post id.
* @param array $job_data The array of job data sent from the multi poster.
*/
function hd_reset_job_facets( $job_post_id, $job_data ) {
// if facetwp is active.
if ( function_exists( 'FWP' ) ) {
// run the indexer for the newly created job post.
FWP()->indexer->index( absint( $job_post_id ) );
}
}
add_action( 'jobrelay_wpcon_job_inserted_complete', 'hd_reset_job_facets', 30, 3 );
