The difficulty together with your code is that the get_metadata() operate returns an array of values, not a single worth. So if you concatenate $first and $final variables on this line $title = $first . ‘ ‘ . $final;, you’re really concatenating two arrays, which leads to the “Array Array” title.
To repair this, you should use the get_post_meta() operate as a substitute of get_metadata() to retrieve the primary and final identify values as follows:
$first = get_post_meta( $post_id, 'first_name', true ); //meta for first identify
$final = get_post_meta( $post_id, 'last_name', true ); //meta for final identify
The third parameter true within the get_post_meta() operate specifies that you just need to retrieve a single worth as a substitute of an array of values.
Here is the up to date code:
add_filter( 'save_post_practitioners', 'hexagon_practitioner_set_title',
10, 3 );
operate hexagon_practitioner_set_title ( $post_id, $put up, $replace ){
//This quickly removes filter to stop infinite loops
remove_filter( 'save_post_practitioners', __FUNCTION__ );
//get first and final identify meta
$first = get_post_meta( $post_id, 'first_name', true ); //meta for first
identify
$final = get_post_meta( $post_id, 'last_name', true ); //meta for final
identify
$title = $first . ' ' . $final;
//replace title
wp_update_post( array( 'ID'=>$post_id, 'post_title'=>$title ) );
//redo filter
add_filter( 'save_post_practitioners', __FUNCTION__, 10, 3 );
}
This could set the put up title to “First Identify Final Identify” as you supposed.
