Restrict Index Table based Search to search only in PDFs in Working Papers

[Bochumer57Participant]

We have four CPTs: JWE-Issues, JWE-Articles, JWE-Reviews and Working Papers. Some of them with PDFs attached. All 265 Working Papers have one PDF each. I built the Index Table and a search in Working Papers to search ONLY! in the PDF content. It is working but the results are showing PDFs from other CPTs too. I tried a lot of different settings but i am not able to restrict the search to search only in the content of the Working Paper PDFs.

In general: Is that posibble and of so, where do i find the correct setting?

Thanks in advance. I tried a lot of different search plugins. Yours is by far the very best.

Hi,

Thank you very much for your kind words!

Unfortunately this is not possible I’m afraid. I can try suggesting a custom coded solution, but it may not work in all cases, or at all.

add_filter('asp_results', 'asp_remove_attachments_by_cpt', 10, 1);
function asp_remove_attachments_by_cpt($results) {
	foreach ( $results as $k => &$r ) {
		if ( $r->content_type == 'attachment' ) {
			$p = get_post(wp_get_post_parent_id($r->id));
			if ( $p->post_type != 'working_paper' ) {
				unset($results[$k]);
			}
		}
	}
	return results;
}

Try adding this code to the functions.php file in your theme/child theme directory – make sure to have a full server back-up first for safety. For more details you can check the safe coding guidelines.

Hello Ernest

Thank you for your response.
The codeyou provided doesn’t work.
I will try to find other setting.

All right, I am not sure why it does not work though.
