Question

我已经构建了一个php表单已经有一段时间了，并且已经通过了验证的各个阶段。我已经决定用php验证了。然而;如果验证失败，我无法弄清楚如何终止脚本或中止提交。我原以为它会像exit()

一样简单

在这里，我在哪里;

// condition 
  $cont = '';
  $msg = '';

// define variables and set to empty values
$fnameErr = $lnameErr = $titleErr = $emailErr = $dayErr = $monthErr = $timeErr = $chkErr = "";
$fnameField = $lnameField = $titleField = $emailField = $daySelect = $monthSelect = $timeSelect = $chk = "";

if ($_SERVER["REQUEST_METHOD"] == "POST") {
  if (empty($_POST["time"])) {
    $timeErr = "Please select a time from the list";
    exit();
  } else {
    $timeSelect = test_input($_POST["time"]);
  }

}
  function test_input($data) {

  $data = trim($data);
  $data = stripslashes($data);
  $data = htmlspecialchars($data);

  return $data;
}

if (isset($_POST['btn-sub'])) {
  // code executed on submit 
  $headers = "From: $emailField\r\n";
  $headers .= "Content-type: text/html\r\n";
  $success = mail($emailAcc, $emailSub, $body, $headers); 

  if(!$success) {   
    $cont = "<b>Fatal Error:</b> Mail was not sent successfully.";
    exit(); 
  } else {
    $cont = "Success! Thank you! <br/> We'll see you there...";
    $msg = "Someone will be in touch with you shortly to confirm your details. Please check the supplied informaiton is correct below;";
  } 
} else {
   // code executed on first request
}

任何我能朝正确方向前进的推动都会有很大的帮助。

注意： 我只提供了一个验证，以使帖子更紧凑。

**在聊天中回答** 我自己的愚蠢导致了这个问题。（我只是设置变量，如果它们没有被调用，那么脚本永远不会到达exit();，感谢所有的变量。

我已尝试使用exit（）或die（），它们都能正常工作。这是我的代码段：

if ($_SERVER["REQUEST_METHOD"] == "POST") 
{
    //validate post variable != empty
    if (empty($_POST['name'])|| empty($_POST['lastname'])|| empty($_POST['email'])|| empty($_POST['phone']) ||empty($_POST['cellphone']) ||empty($_POST['dir'])) 
    {
    $response = json_encode(array("error" => "true","message" => "Error, please fill all the form data"));
    echo $response;
    exit();
}else{
    .
    .
    .
}

}

如果验证失败，则中止提交php
