我有一个代码部分，负责从联系人表单中获取变量，并向我和我的同事发送电子邮件。

add_action(\'wp_ajax_nopriv_submit_contact_form\', \'submit_contact_form\'); 
// Send information from the contact form
function submit_contact_form(){

    // If there is a $_POST[\'email\']...
    if( isset($_POST[\'email\']) && ($_POST[\'validation\'] == true ) ) {

        $email = $_POST[\'email\'];       
        $email_to = "aaaa@example.pro";
        $fullname = $_POST[\'fullname\'];
        $headers = \'From: \'. $fullname .\' <\'. $email .\'>\' . "\\r\\n";
        $group_emails = array(
            \'bbb@example.com\', 
            \'ccc@example.com\', 
            \'ddd@example.com\', 
            \'eee@example.pro\', 
            \'fff@example.pro\' 
            );
        $email_subject = "example intro: $email";
        $message = $_POST[\'text\']; 

        if(wp_mail($group_emails,$email_subject,$message,$headers)) {
            echo json_encode(array("result"=>"complete"));
        } else {
            echo json_encode(array("result"=>"mail_error"));
            var_dump($GLOBALS[\'phpmailer\']->ErrorInfo);
    }
        wp_die();
    }
}

我怎样才能做到这一点？我尝试了几种不同的写作方法，但没有成功。
