我刚刚将我的站点从一台服务器移动到另一台服务器，都在bluehost上

但我得到了这个错误

Parse error: syntax error, unexpected T_FUNCTION in /home2/energzk2/public_html/wp-content/themes/energy/functions/contact.php on line 3

下面是该文件的几行代码

<?php 
/*Add meta boxes to contact page*/
add_action( \'add_meta_boxes_page\', function( \\WP_Post $post ) {

    global $post;

    if(!empty($post)){
        $pageTemplate = get_post_meta($post->ID, \'_wp_page_template\', true);

        if($pageTemplate == \'page-contact.php\' ){
        add_meta_box(\'contact_meta_1\', \'Contact Details\', \'contact_details\', \'page\', \'normal\', \'high\');
        add_meta_box(\'contact_meta_2\', \'Social  Details\', \'social_details\', \'page\', \'normal\', \'high\');
        add_meta_box(\'contact_meta_3\', \'Footer  Details\', \'footer_section\', \'page\', \'normal\', \'high\');
        add_meta_box(\'contact_meta_4\', \'Copyright\', \'copyright\', \'page\', \'normal\', \'high\');

    }
   }
 },1);

我尝试了@Howdy\\u McGee给出的解决方案，它奏效了。但我收到了这个警告
