Register CPT UI to frontend search

Have you made sure the post type is 1) public, 2) publicly queryable, and 3) not excluded from search? Logically there’s no reason you should be having to include it manually.

That said, regarding your code above, I’d recommend checking if is_admin() and return early in those cases. Will prevent affecting your backend searches.

function my_cptui_add_post_type_to_search( $query ) {
	if ( is_admin() ) {
		return;
	}

	if ( $query->is_search() ) {
		// Replace these slugs with the post types you want to include.
		$cptui_post_types = array( 'mitarbeiter', 'referenzen', 'infothekbeitrag', 'partner', 'referenzbericht', 'jobboerse'     );

		$query->set(
			'post_type',
			array_merge(
				array( 'post' ),
				$cptui_post_types
			)
		);
	}
}
add_filter( 'pre_get_posts', 'my_cptui_add_post_type_to_search' );

Dear Michael

checked your remarks:

1. CPTs are public –> active
2. CPTs are publicly queryable –> active
3. CPTs exlude from search –> deactivated

Tried your code –>

Without code nothing works, no search results. With code no search result in ajax search window but results on search page.

Your code workd also without backend problems. Is there a way to include search results to ajax search? Old code code showed results also for ajax but with with the problem of backend search errors….

if ( is_admin() ) {
		return;
	}

this code line prevent the mistakes but in backend but also the showing of search results in the ajax search.

Thanks for your help Marc

Ah, AJAX search would be negated by the is_admin() since WP’s AJAX has to load a certain amount of the WP Admin.

You could use if ( defined( 'DOING_AJAX' ) && DOING_AJAX ) { ... } to amend the conditions or possibly nest some if statements.

Dear Michael

you mean this way:

function my_cptui_add_post_type_to_search( $query ) {
	if ( defined( 'DOING_AJAX' ) && DOING_AJAX ) {
		return;
	}

	if ( $query->is_search() ) {
		// Replace these slugs with the post types you want to include.
		$cptui_post_types = array( 'mitarbeiter', 'referenzen', 'infothekbeitrag', 'partner', 'referenzbericht', 'jobboerse'     );

		$query->set(
			'post_type',
			array_merge(
				array( 'post' ),
				$cptui_post_types
			)
		);
	}
}
add_filter( 'pre_get_posts', 'my_cptui_add_post_type_to_search' );

I can’t say for sure if that’s the correct method to go about it because it’s a bit of a unique case and I am not set up to test for sure.

You’d want to return early, for sure, if doing a search from the admin, and you may want both standard and AJAX search if from the frontend. The version you have above would have it work for only non-ajax cases. Maybe check if not doing ajax, and then a second if statement that check if is_admin. That would make AJAX work fine, and then if not, also checks if frontend or not.

if ( not ajax ) { if ( is_admin() ) { return early } }
