我正在尝试修复其他人创建的网站，并且我试图在表单上显示验证错误。我已经尝试过高低搜索，无法让它发挥作用。例如，如果电话号码少于2个字符，它将在表单上显示错误消息，而不是弹出窗口。如果一切都通过验证，表格将通过电子邮件发送。
目前，问题是如果有人输入的信息未通过验证，则不会显示任何错误，客户认为他们向我们发送了电子邮件。
这是联系表格：
<?php
ini_set('display_errors', 1);
session_start();
include("captcha.php");
$_SESSION['captcha'] = simple_php_captcha();
if($_POST){
include("contact_process.php");
}
?>
