我想从不同页面的一个自定义字段以及页面标题中获取内容，我使用以下代码：

<?php
    $mypages = get_pages( array(
    \'sort_order\' => \'ASC\',
    \'sort_column\' => \'post_title\',
    \'hierarchical\' => 1,
    \'exclude\' => \'\',
    \'include\' => \'\',
    \'meta_key\' => \'\',
    \'meta_value\' => \'\',
    \'authors\' => \'\',
    \'child_of\' => 53,
    \'parent\' => -1,
    \'exclude_tree\' => \'\',
    \'number\' => \'\',
    \'offset\' => 0,
    \'post_type\' => \'page\',
    \'post_status\' => \'publish\'
 ) );

    foreach( $mypages as $page ) {      
        $content = $page->post_content;
                $new = $page->get_post_custom_values(\'new_file\');
        if ( ! $content ) // Check for empty page
            continue;

        $content = apply_filters( \'the_content\', $content );
    ?>
        <h2><a href="<?php echo get_page_link( $page->ID ); ?>"><?php echo $page->post_title; ?></a></h2>

                        <a style="display:block; text-align: center;" title="Download Now" href="<?php $new;  ?>"><img src="<?php bloginfo(\'template_url\'); ?>/images/new-file.png" alt="Download the File" /></a>


    <?php
    }   
?>

我可以获取页面标题，但无法获取自定义字段值。请在这方面指导我。在这方面，我们将非常感谢您的帮助。

$new = $page->get_post_custom_values(\'new_file\');

$new = get_post_custom_values(\'new_file\', $page->ID);

$new = get_post_meta($page->ID, \'new_file\', true);
