PHP联系人表单通过HTML5验证，显示消息

PHP contact form with HTML5 validation, display a message?

本文关键字：验证 显示 消息 HTML5 联系人 表单 PHP | 更新日期: 2023-09-27

我有一个可工作的php联系人表单，对输入进行了HTML5验证（添加了必需的内容，并键入名称/电子邮件），但我遇到了一个问题。

当消息被发送时，它会打开一个新的选项卡，上面写着谢谢你的消息被发送了，这是正常的，因为process.php

<?php
//Retrieve form data. 
//GET - user submitted data using AJAX
//POST - in case user does not support javascript, we'll use POST instead
$name = ($_GET['name']) ? $_GET['name'] : $_POST['name'];
$email = ($_GET['email']) ?$_GET['email'] : $_POST['email'];
$website = ($_GET['website']) ?$_GET['website'] : $_POST['website'];
$comment = ($_GET['comment']) ?$_GET['comment'] : $_POST['comment'];
//flag to indicate which method it uses. If POST set it to 1
if ($_POST) $post=1;
//Simple server side validation for POST data, of course, 
//you should validate the email
if (!$name) $errors[count($errors)] = 'Please enter your name.';
if (!$email) $errors[count($errors)] = 'Please enter your email.'; 
if (!$comment) $errors[count($errors)] = 'Please enter your message.'; 
//if the errors array is empty, send the mail
if (!$errors) {
    //recipient - change this to your name and email
    $to = 'youremail@email.com';    
    //sender
    $from = $email;
    //subject and the html message
    $subject = 'Hello from ' . $name;    
    $message = '
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head></head>
    <body>
    <table>
        <tr><td>Name: </td><td>' . $name . '</td></tr>
        <tr><td>Email: </td><td>' . $email . '</td></tr>
        <tr><td>Message: </td><td>' . nl2br($comment) . '</td></tr>
    </table>
    </body>
    </html>';
    //send the mail
    $result = sendmail($to, $subject, $message, $from);
    //if POST was used, display the message straight away
    if ($_POST) {
        if ($result) echo 'Thank you! We have received your message.';
        else echo 'Sorry, unexpected error. Please try again later';
    //else if GET was used, return the boolean value so that 
    //ajax script can react accordingly
    //1 means success, 0 means failed
    } else {
        echo $result;    
    }
//if the errors array has values
} else {
    //display the errors message
    for ($i=0; $i<count($errors); $i++) echo $errors[$i] . '<br/>';
    echo '<a href="index.html">Back</a>';
    exit;
}
//Simple mail function with HTML header
function sendmail($to, $subject, $message, $from) {
    $headers = "MIME-Version: 1.0" . "'r'n";
    $headers .= "Content-type:text/html;charset=iso-8859-1" . "'r'n";
    $headers .= 'From: ' . $from . "'r'n";
    $result = mail($to,$subject,$message,$headers);
    if ($result) return 1;
    else return 0;
}
?>

但我如何才能让它在提交按钮下显示消息？这是HTML端的

    <form method="post" action="process.php">
<div class="element">
    <label><i class="icon-user"></i></label>
    <input type="name" name="name" placeholder="write your name here" class="text" required/>
</div>
<br>
<div class="element">
    <label><i class="icon-envelope"></i></label>
    <input type="email" name="email" placeholder="write your e-mail here" class="text" required/>
</div>
<br>
<div class="element">
    <label><i class="icon-comment"></i></label>
    <textarea name="comment" placeholder="write your message here" class="text textarea"required></textarea>
</div>
<br>
<div class="element el-submit">
    <input class="submit" type="submit" id="submit"/>
</div>
</form>

我的意思是，当我按下提交按钮时，我想显示一条类似"您的消息已发送"的消息，但我希望它在提交按钮下，而不是在新页面

中

将文件合并为一个文件，以便将D_1数据POST到下面的相同文件中

<?php
if($_POST) //If the form is submitted
{
$notification="";  //Used for catching all your messages
//Retrieve form data. 
//GET - user submitted data using AJAX
//POST - in case user does not support javascript, we'll use POST instead
$name = ($_GET['name']) ? $_GET['name'] : $_POST['name'];
$email = ($_GET['email']) ?$_GET['email'] : $_POST['email'];
$website = ($_GET['website']) ?$_GET['website'] : $_POST['website'];
$comment = ($_GET['comment']) ?$_GET['comment'] : $_POST['comment'];
//flag to indicate which method it uses. If POST set it to 1
if ($_POST) $post=1;
//Simple server side validation for POST data, of course, 
//you should validate the email
if (!$name) $errors[count($errors)] = 'Please enter your name.';
if (!$email) $errors[count($errors)] = 'Please enter your email.'; 
if (!$comment) $errors[count($errors)] = 'Please enter your message.'; 
//if the errors array is empty, send the mail
if (!$errors) {
//recipient - change this to your name and email
$to = 'youremail@email.com';    
//sender
$from = $email;
//subject and the html message
$subject = 'Hello from ' . $name;    
$message = '
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

</html>';
//send the mail
$result = sendmail($to, $subject, $message, $from);
//if POST was used, display the message straight away
if ($_POST) {
    if ($result) echo 'Thank you! We have received your message.';
    else $notification.= 'Sorry, unexpected error. Please try again later';
//else if GET was used, return the boolean value so that 
//ajax script can react accordingly
//1 means success, 0 means failed
} else {
    $notification.= $result;    
}
//if the errors array has values

for ($i=0; $i<count($errors); $i++) echo $errors[$i] . '<br/>';

    $headers .= 'From: ' . $from . "'r'n";
    $result = mail($to,$subject,$message,$headers);
    if ($result) return 1;
    else return 0;
}
} //First If loop
?>
<form method="post" action="process.php">
<div class="element">

<?php
if(!empty($notification)) //This will display notification after submit

echo $notification;

</form>

您还可以使用AJAX来实现所需的功能。以下教程是最好的示例。

如果您不想在下一页上显示这一点，请创建弹出窗口以显示感谢信息，它看起来很棒。以这种方式使用html代码。

<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Untitled Document</title>
<script>
function myFunction()
{
alert("Thanks for  mail!");
}
</script>
</head>
<body>
<form method="post" action="process.php">
<div class="element">
    <label><i class="icon-user"></i></label>
    <input type="name" name="name" placeholder="write your name here" class="text" required/>
</div>
<br>
<div class="element">
    <label><i class="icon-envelope"></i></label>
    <input type="email" name="email" placeholder="write your e-mail here" class="text" required/>
</div>
<br>
<div class="element">
    <label><i class="icon-comment"></i></label>
    <textarea name="comment" placeholder="write your message here" class="text textarea"required></textarea>
</div>
<br>
<div class="element el-submit">
    <input type="button" onclick="myFunction()" value="Submit">
</div>
</form>
</body>
</html>

到目前为止，回复中遗漏的重要一点是，如果删除服务器端PHP，应该将action="some.php"更改为action=""；因此，"post"的操作在联系表单中。我在这里找到了一个关于HTML5CS3和PHP的全面教程。
