沒有現成的過濾器之類的東西，可以讓你做到這一點，但你可以過濾the_content，把它完成。

function so33675604_add_class_to_checkout($content) { 
    //condition to check for the proper page 
    if (is_checkout()) : 
     //disable error reporting for falsy formatted html code 
     libxml_use_internal_errors(true); 

     //parse the $content html (treat content as UTF-8, don't add any doctype or other html wrappers) 
     $html = new DOMDocument(); 
     $html->loadHTML(mb_convert_encoding($content, 'HTML-ENTITIES', 'UTF-8'), LIBXML_HTML_NOIMPLIED | LIBXML_HTML_NODEFDTD); 

     //search for the very first div 
     $container = $html->getElementsByTagName('div')->item(0); 
     //add classes (remember to put woocommerce, since thats been used by some js functions) 
     $container->setAttribute('class', 'woocommerce oink'); 

     //return the result 
     return $html->saveHTML(); 
    endif; 
    return $content; 
} 
//add the filter (priority must be high, so it runs later, after the shortcodes have been processed) 
add_filter('the_content', 'so33675604_add_class_to_checkout', 100); 

請注意，這個函數使用條件語句和這些可能無法在WP-AJAX調用工作/你會找到另一種方法來檢查，如果檢出（或其它），很可能是通過全球wp_query。
