访问域时表单操作更改为 mail.php

Question

我正在使用一个基本的 php 来从一个网站给自己发邮件。
它是一个包含所需 PHP 的单页网站，而不是单独的 mail.php。我使用了内置的验证和必填字段，但是当我访问域而不是 domain/index.php 时，表单代码会更改以执行操作 mail.php，不会进行验证并发送空白电子邮件。

我希望它包含所有必填字段，经过验证，然后显示一条成功的小消息，让用户知道他们的消息已发送。 我在下面附上了我的代码。

<?php            
if($_SERVER["REQUEST_METHOD"] == "POST"){
   $name = test_input($_POST["name"]);
   $email = test_input($_POST["email"]);
   $message = test_input($_POST["message"]);
   $formcontent="From: $name \n Message: $message";
   $recipient = "me@domian";
   $subject = "Contact Form Subbmission";
   $mailheader = "From: $email \r\n";
   mail($recipient, $subject, $formcontent, $mailheader) or die("Error!");
   echo ("Thanks for getting in touch, I'll get back to you as soon as possible.");
}
//clean it
function test_input($data){
   $data = trim($data);
   $data = stripslashes($data);
   $data = htmlspecialchars($data);
   return $data;
}
?>

<form method="post" action="<?php echo htmlspecialchars($_SERVER['REQUEST_URI']);?>#contact">
<div class="row 50%">
<div class="6u"><input type="text" name="name" placeholder="Name" required="required"/></div>
<div class="6u"><input type="email" name="email" placeholder="Email" required="required"/></div>
</div>
<div class="row 50%">
<div class="12u"><textarea name="message" placeholder="Message" rows="6" required="required">    </textarea></div>
</div>
<div class="row">
<div class="12u">
<ul class="actions">
<li><input type="submit" value="Send Message" /></li>
</ul>
</div>
</div>
</form>

提前感谢您提供的任何帮助

试试这个：

<?php
//checks if the post variables are set and also checks that they aren't empty         
if(isset($_POST['name'],$_POST['email'],$_POST['message'])&& $_POST['name'] !="" && $_POST['email'] !="" && $_POST['message'] !=""){
   $name = test_input($_POST["name"]);
   $email = test_input($_POST["email"]);
   $message = test_input($_POST["message"]);
   $formcontent="From: $name \n Message: $message";
   $recipient = "me@domian";
   $subject = "Contact Form Subbmission";
   $mailheader = "From: $email \r\n";
   mail($recipient, $subject, $formcontent, $mailheader);
   echo 'Thanks for getting in touch, I\'ll get back to you as soon as possible.';
   }else{
   echo 'You didn\'t fill out all the fields. Please try again';
 }
//clean it
function test_input($data){
   $data = trim($data);
   $data = stripslashes($data);
   $data = htmlspecialchars($data);
   return $data;
 }
?>

<form action="index.php" method="post">
<div class="row 50%">
<div class="6u"><input type="text" name="name" placeholder="Name" required="required"/></div>
<div class="6u"><input type="email" name="email" placeholder="Email" required="required"/></div>
</div>
<div class="row 50%">
<div class="12u"><textarea name="message" placeholder="Message" rows="6" required="required"></textarea></div>
</div>
<div class="row">
<div class="12u">
<ul class="actions">
<li><input type="submit" value="Send Message" /></li>
</ul>
</div>
</div>
</form>

在任何情况下，都使用更好的错误处理，然后使用邮件功能“或死”。

例如;

<?php
 if(mail($recipient, $subject, $formcontent, $mailheader)){
     echo ("Thanks for getting in touch, I'll get back to you as soon as possible.");
 }
?>

您的表单不需要此操作。如果它发布到域本身，请使用以下内容：

<form method="post" action="#contact">

我刚刚在服务器上单独做了一个mail.php文件，这个项目已经超期了。
