打印PHP联系表单上方的消息

嘿所有，我有一个基本的HTML联系表单，在单击提交按钮后会转到.php文件。目前，如果用户按下提交时没有错误，则会将它们带到一个单独的页面，上面写着“感谢您与我们联系......”。是否可以在点击提交时在联系表单上方打印该邮件？我真的希望他们留在当前页面而不是被重定向。

这是HTML表单：

<form name="contactform" method="post" action="scripts/contactform.php">
<table width="450px">
</tr>
<tr>
 <td valign="top">
  <label for="first_name"><b>Name *</b></label>
 </td>
 <td valign="top">
  <input  type="text" name="first_name" maxlength="50" size="30">
 </td>
</tr>

<tr>
 <td valign="top">
  <label for="email"><b>Email Address *</b></label>
 </td>
 <td valign="top">
  <input  type="text" name="email" maxlength="80" size="30">
 </td>

</tr>
<tr>
 <td valign="top">
  <label for="telephone"><b>Telephone</b></label>
 </td>
 <td valign="top">
  <input  type="text" name="telephone" maxlength="30" size="30">
 </td>
</tr>
<tr>
 <td valign="top">
  <label for="message">Message: *</label>
 </td>
 <td valign="top">
  <textarea  name="message" maxlength="1000" cols="40" rows="8"></textarea>
 </td>

</tr>
<tr>
 <td colspan="2" style="text-align:center">
  <input type="submit" value="Submit" style="height:35px; width:90px;">
 </td>
</tr>
</table>
</form>

这是contactform.php文件：

<?php
if(isset($_POST['email'])) {

    // EDIT THE 2 LINES BELOW AS REQUIRED
    $email_to = "email@domain.com";
    $email_subject = "Contact Form";


    function died($error) {
        // your error code can go here
        echo "We are very sorry, but there were error(s) found with the form you submitted. ";
        echo "These errors appear below.<br /><br />";
        echo $error."<br /><br />";
        echo "Please go back and fix these errors.<br /><br />";
        die();
    }

    // validation expected data exists
    if(!isset($_POST['first_name']) ||
        !isset($_POST['last_name']) ||
        !isset($_POST['email']) ||
        !isset($_POST['Telephone']) ||
        !isset($_POST['message'])) {
        died('We are sorry, but there appears to be a problem with the form you submitted.');      
    }

    $first_name = $_POST['first_name']; // required
    $last_name = $_POST['last_name']; // required
    $email_from = $_POST['email']; // required
    $telephone = $_POST['telephone']; // not required
    $comments = $_POST['message']; // required

    $error_message = "";
    $email_exp = "^[A-Z0-9._%-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$";
  if(!eregi($email_exp,$email_from)) {
    $error_message .= 'The Email Address you entered does not appear to be valid.<br />';
  }
    $string_exp = "^[a-z .'-]+$";
  if(!eregi($string_exp,$first_name)) {
    $error_message .= 'The First Name you entered does not appear to be valid.<br />';
  }
  if(!eregi($string_exp,$last_name)) {
    $error_message .= 'The Last Name you entered does not appear to be valid.<br />';
  }
  if(strlen($comments) < 2) {
    $error_message .= 'The Comments you entered do not appear to be valid.<br />';
  }
  if(strlen($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);
    }

    $email_message .= "Name: ".clean_string($first_name)."\n";
    $email_message .= "Email: ".clean_string($email_from)."\n";
    $email_message .= "Telephone: ".clean_string($telephone)."\n";
    $email_message .= "Message: ".clean_string($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); 
?>

您需要使用AJAX。以下是您要执行的操作的示例：

答案 2 :(得分：0)

最好的办法是将您的联系表单作为PHP文件，以便它可以有条件地显示错误消息。

您可以通过以下两种方式之一来实现：

  1. 如果发生错误，请将contactform.php文件重定向回HTML表单。在这种情况下，您必须将错误消息保存到会话变量。
  2. 将所有表单处理包含在HTML表单的顶部，并让表单的操作指向自身。

    3. 然后，在表单正上方，只包含类似

    的内容 
    <?php if (!empty($error_message)): ?>
    <p class="error"><?php echo $error_message; ?></p>
<?php endif; ?>
