[Plugin: Posts 2 Posts] Search for Object in Connection Meta box not working

Hi scribu,

I’ve got same problem like this one, I try to connect between 2 post type, “article” and “company”, If I click “View All” link at edit “article” post it will show all “company” post, but if I type something in search box it’ll show all post from another post type except from “company”, this is my register script :

I already try to disable all plugins and ONLY activated the Posts 2 Posts plugins but it still have same issue, I hope you can help me with this issue.

Note : I’m using WordPress v.3.4 with WPMU enabled and p2p v.1.3.1 if that can help you with.

Hi All,

Just wanted to weigh in here because I figured out with the help of the questions here as well as that linked post by rolies106 that you need to be really careful when modifying the main query with WordPress. I needed to make only the blog posts show on a search (instead of all pages) so I put a filter on pre_get_posts like so:

function searchfilter( $query ) {
	if ( $query->is_search ) {
		$query->set( 'post_type','post' );
	}
	return $query;
}
add_filter( 'pre_get_posts', 'searchfilter' );

Then I’m wondering why the Search function on Posts to Posts relations isn’t working and only showing blog posts because I did this way after I set all of that up. Then it hit me: simply add the check on the if conditional !is_admin(). I did this and it’s working great again because it’s not adding this filter to any admin sections. This would also mess up ANY search functionality on the admin without that check.

Fixed code:

function searchfilter( $query ) {
	if ( $query->is_search && ! is_admin() ) {
		$query->set( 'post_type','post' );
	}
	return $query;
}
add_filter( 'pre_get_posts', 'searchfilter' );
