Question

我有联系表单的HTML和PHP代码。当有人输入如下字符：š，đ，ž，č和ć（UTF-8）字符时，脚本报告的错误很少。

1。如何在$ first_name和$ last_name输入表单中添加UTF-8输入？

接下来的问题是，Java Script弹出错误或成功的消息。如果我输入名称框“šđžčć”并在姓氏框中输入“šđžčć”脚本，则会重新显示三个消息：

错误的名字
错误的姓氏
请再试一次（不完全是这样但有些消息）

这意味着 - 三个弹出窗口！你得到一个 - 你关闭它，然后第二个 - 关闭它，等等，这是令人沮丧的。我的第二个问题：

2。如何重写这个PHP，并将所有消息和错误放在一个函数/值/消息中，只弹出一个说：错误的名字，姓氏，我爱你等。

PHP代码：

<?php
 
if(isset($_POST['email'])) {
 
     
 
    // EDIT THE 2 LINES BELOW AS REQUIRED
 
    $email_to = "you@yourdomain.com";
 
    $email_subject = "Your email subject line";
 
     
 
     
 
    function died($error) {
 
        // your error code can go here
 
        echo "<script type='text/javascript'>alert('error')</script>";
 
        echo "<script type='text/javascript'>alert('these errors apears below')</script>";
 
        echo $error."<br /><br />";
 
        echo "<script type='text/javascript'>alert('please fix errors')</script>";
 
        die();
 
    }
 
     
 
    // validation expected data exists
 
    if(!isset($_POST['first_name']) ||
 
        !isset($_POST['last_name']) ||
 
        !isset($_POST['email']) ||
 
        !isset($_POST['telephone']) ||
 
        !isset($_POST['comments'])) {
 
        died(<script type='text/javascript'>alert('Submitted successfully!')</script>');       
 
    }
 
     
 
    $first_name = $_POST['first_name']; // required
 
    $last_name = $_POST['last_name']; // required
 
    $email_from = $_POST['email']; // required
 
    $telephone = $_POST['telephone']; // not required
 
    $comments = $_POST['comments']; // required
 
     
 
    $error_message = "";
 
    $email_exp = '/^[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/';
 
  if(!preg_match($email_exp,$email_from)) {
 
    $error_message .= '<script type='text/javascript'>alert('wrong email !')</script>';
 
  }
 
    $string_exp = "/^[A-Za-z .'-]+$/";
 
  if(!preg_match($string_exp,$first_name)) {
 
    $error_message .= '<script type='text/javascript'>alert('invalid firs name')</script>';
 
  }
 
  if(!preg_match($string_exp,$last_name)) {
 
    $error_message .= '<script type='text/javascript'>alert('invalid last name')</script>';
 
  }
 
  if(strlen($comments) < 2) {
 
    $error_message .= '<script type='text/javascript'>alert('invalid message')</script>';
 
  }
 
  if(strlen($error_message) > 0) {
 
    died($error_message);
 
  }
 
    $email_message = "Form details below.\n\n";
 
     
 
    function clean_string($string) {
 
      $bad = array("content-type","bcc:","to:","cc:","href");
 
      return str_replace($bad,"",$string);
 
    }
 
     
 
    $email_message .= "First Name: ".clean_string($first_name)."\n";
 
    $email_message .= "Last Name: ".clean_string($last_name)."\n";
 
    $email_message .= "Email: ".clean_string($email_from)."\n";
 
    $email_message .= "Telephone: ".clean_string($telephone)."\n";
 
    $email_message .= "Comments: ".clean_string($comments)."\n";
 
     
 
     
 
// create email headers
 
$headers = 'From: '.$email_from."\r\n".
 
'Reply-To: '.$email_from."\r\n" .
 
'X-Mailer: PHP/' . phpversion();
 
@mail($email_to, $email_subject, $email_message, $headers);  
 
?>
 
 
 
<!-- include your own success html here -->
 
 
 
echo "<script type='text/javascript'>alert('Submitted successfully!')</script>"
 
 
 
<?php
 
}
 
?>
