我一直在尝试附加多个页面，eash到其页面模板使用foreach循环。。。手动意味着编写每个页面的代码可以工作，但在foreach循环中它无法工作。

我有几个这样的foreach循环，所以我不想手动执行，也希望了解/理解问题。。。这是我的密码

请注意，只需添加带有值的自定义字段即可。。（奇怪）我做错了什么。

$start_number   = 2;
$iim_pages  = array(\'tools\', \'clients\', \'users\', \'resources\', \'data\', \'data2\', \'settings\');

foreach($iim_pages as $page) {

    $page_title     =   ucwords(str_replace(\'-\', \' \', $page));
    $page_filename      =   \'page-\'.$page.\'.php\';

    //don\'t change the code bellow, unless you know what you\'re doing

    $page_check = get_page_by_title($page_title);
    $new_page = array(
        \'post_type\'     => \'page\',
        \'menu_order\'    => $start_number,       
        \'post_title\'    => $page_title,
        \'post_content\'  => \'\',
        \'post_status\'   => \'publish\',
        \'post_author\'   => 1,
    );
    if(!isset($page_check->ID)){
        $new_page_id = wp_insert_post($new_page);

        // DOESENT WORK WITH ADD_POST_META or UPDATE_POST_META
        add_post_meta($new_page_id, \'_wp_page_template\', $page_filename);  

        // THIS WORKS!
        add_post_meta($new_page_id, \'testmeta\', $page_filename);  
    }

    $start_number++;
}
