我在下面拼凑了一些 PHP 代码，这些代码通过 Ajax 表单提交创建了一个漂亮的 HTML 电子邮件，并带有一个表格。但是，我想让它在输入的时间范围小于 48 小时时弹出错误消息。我想知道改变 html 和 php 以使其工作的最简单方法是什么，或者是否有可能。

HTML 代码

<input name="Event Date" type="text" required id="Event Date" style="border-radius:5px; height:25px; font-family:'Quicksand', sans-serif; color:#666" title="Event Date" value="MM/DD/YYYY">

PHP 代码

    <?php

 require_once('recaptchalib.php');
 $privatekey = "###########################";
 $resp = recaptcha_check_answer ($privatekey,
                                 $_SERVER["REMOTE_ADDR"],
                                 $_POST["recaptcha_challenge_field"],
                                 $_POST["recaptcha_response_field"]);
unset($_POST["recaptcha_challenge_field"]);
unset($_POST["recaptcha_response_field"]);
 if (!$resp->is_valid) {
   // What happens when the CAPTCHA was entered incorrectly
   die ("The human verification code above WAS NOT entered correctly, please reset the human verification code and try again :-) " .
        "(Error: " . $resp->error . ")");
 } else {
     // Code Below For Handling Form (Send Email)
   function validEmail($email)
{
   $isValid = true;
   $atIndex = strrpos($email, "@");
   if (is_bool($atIndex) && !$atIndex)
   {
      $isValid = false;
   }
   else
   {
      $domain = substr($email, $atIndex+1);
      $local = substr($email, 0, $atIndex);
      $localLen = strlen($local);
      $domainLen = strlen($domain);
      if ($localLen < 1 || $localLen > 64)
      {
         // local part length exceeded
         $isValid = false;
      }
      else if ($domainLen < 1 || $domainLen > 255)
      {
         // domain part length exceeded
         $isValid = false;
      }
      else if ($local[0] == '.' || $local[$localLen-1] == '.')

         $isValid = false;
      }

尝试这样的事情，看看 Event Time 和 Time 实际被评估为什么。

//48 Hour Time Limit
if ((strptime($_POST['Event Date'], "%m/%d/%Y") - time()) < (48 * 60 * 60)) {
    echo "Event Time: " . strptime($_POST['Event Date']) . "\n";
    echo "Time: " . time() . "\n";
    echo "Date is under 48 hours notice. Please call for service."; 
    exit();
}
