I'm trying to not show certain posts in the admin area based on the page template. Here is what I have so far:

add_filter( 'parse_query', 'hide_some_posts' );

function hide_some_posts( $query ) {
    global $pagenow;
    $myHiddenPosts = array('10667');
    if ( is_admin() && $pagenow=='edit.php') {
       $query->set( 'post__not_in', $myHiddenPosts );
    }
}

This works perfectly based on page ID, but I'm looking to do this based on the page template instead. I came across this:

    $query->set('meta_key','_wp_page_template');
    $query->set('meta_value', 'page-some-template.php'); //Change filename to yours

But how can I make it so that only works for including. I would like to not include pages based on the template.

Any way to do this?

Thanks!

• page-template
• pre-get-posts

• Where are you using pre_get_posts? The title of the question might need adjusting. Are you trying to add a condition to hide_some_posts() that checks the template in use for that page? – jdm2112 Commented Apr 18, 2019 at 17:01

You should use meta_query to pass meta query arguments.

add_action('parse_query', 'se334731_filter_admin_post_list');

function se334731_filter_admin_post_list( $query )
{
    $screen = get_current_screen();
    if ( is_admin()  && $screen->post_type == 'page'  && $screen->base == 'edit' )
    {
        $query->query_vars['meta_query'][] = [
            'relation' => 'OR',
            [
                'key' => '_wp_page_template',
                'value'    => 'page-some-template.php',
                'compare'  => '!=',
                //'value'    => array( 'page-some-template.php' ),
                //'compare'  => 'NOT IN'
            ],
            [
                'key' => '_wp_page_template',
                'compare'  => 'NOT EXISTS'
            ],
        ];
    }
}

These changes will not affect the summary of the number of posts (all, published, trashed) above table. To correct the displayed number of posts, use the wp_count_posts filter.
