内存大小修改Wordpress搜索功能时耗尽

I am trying to modify the search function of wordpress to disable posts that have been set to not show in the sitemap via ACF radio button.

When i navigate to the site I am greeted with this lovely error message:

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 130968 bytes) in /Users/***/***/***/***/wp-includes/class-wp-query.php on line 1621

Code:

function exclude_pages_from_search($query) {
    if ( !is_admin() ) {

        $hidePages = new WP_Query( array (
            'meta_key' => 'edit_screen_sitemap',
            'meta_value' => 'hide',
            'fields' => 'ids'
        )); $hidePageIds = implode( ',', $hidePages->posts );
        //print_r($hidePageIds);

        if ( $query->is_main_query() ) {

            if ($query->is_search) {
                $query->set('post__not_in', array($hidePageIds));
            }
        }
    }
}

add_action('pre_get_posts','exclude_pages_from_search');

You need to remove your action from your own query. Otherwise your function will call itself recursively, and exhaust the memory due to infinite recursion. This should do the trick:

// remove our action temporarily 
remove_action('pre_get_posts','exclude_pages_from_search');

$hidePages = new WP_Query( array ( ... //your query
$hidePageIds = implode( ',', $hidePages->posts );

// add the action again
add_action('pre_get_posts','exclude_pages_from_search'); 

if ... //rest of your function
