用于联系表单的PHP脚本

尝试从
更改代码中的这一行如果(收取($ _POST['提交'])){.....................} 如果(收取($ _POST['提交'])){..............}。
这是因为您在表单submit中使用了name="submit"。并尝试使用$_POST['submitted']检查循环。

所以你的代码现在看起来像…

index . php。

<form id="contact" method="post" action="index.php">
<div class="row half">
<?php  //form validation and email sending will go here
//check to see if the form has been completely filled out or not
$completed = false;
if (isset($_POST['submit'])) {
if (!empty($_POST['name'])) {
     $name = $_POST['name'];
} else {
      $name = NULL;
      echo '<p class="error">You forgot to enter your name!</p>';
}
      if (preg_match ('/^['w.-]+@['w.-]+'.[A-Za-z]{2,6}$/', $_POST['email'])) {
        $email = $_POST['email'];
} else {
      $email = NULL;
      echo '<p class="error">Please enter a valid email address.</p>';
}
     if (!empty($_POST['message'])) {
      $comments = $_POST['message'];
} else {
      $comments = NULL;
      echo '<p class="error">Please include your comments.</p>';
}
 //form has been completed, send email 
 if ($name && $email && $comments) {
 //form has been completed, set to true
 $completed = true;
 $to = "champanion@hotmail.com";
 $subject = "Contact Form Submission";
 $message = "Thank you for visiting The Champanion!";
 "Name: " . $name . "'r'n".
 "Email: " . $email . "'r'n".
 "Comments: " . $comments . "'r'n";
 $headers = "From: champanion@hotmail.com 'r'n";
 $headers .= "Cc: ". $email. "'r'n";
 mail($to,$subject,$message,$headers);
 echo '<p class="confirmation">Thank you for contacting us.</br>
 We received your message and will get back to you shortly.</p>';
 } else {  
      //displays if the user has not completely filled out form
      echo '<p class="error">The form has not been filled out completely, please check and try again.</p>';
 } //end if ($name && $email && $comments)
 }//end (isset($_POST['submit'])
?>
<div class="6u">
<input type="text" name="name" placeholder="Name" value="<?php if(isset($_POST['name'])) echo $_POST['name']; ?>"/></div>
<div class="6u">
<input type="text" name="email" placeholder="Email" value="<?php if(isset($_POST['email'])) echo $_POST['email']; ?>"/></div>
</div>
<div class="row half">
<div class="12u">
    <textarea name="message" placeholder="Message" rows="6"><?php if (isset($_POST['comments'])) echo $_POST['comments']; ?></textarea></div>
</div>
<div class="row">
<div class="12u"><ul class="actions">
<li><input type="submit" name="submit" class="button" value="Send Message" /></li>
</ul>
 </div>
</div>
</form>
<?php
 //end if ($completed == false)
?>

看起来可能在代码中出现了混淆。

所以您想在表单完成后验证?将第一个if语句更改为

if (isset($_POST['completed'])) {

尝试删除这个，因为它总是在脚本运行时设置该值，这将导致它每次都运行。将其设置为空将阻止它运行，直到设置好变量。

$completed = false;

将其添加到表单部分。它将设置一个值，并运行验证脚本。

<input type="hidden" name="completed" value="yes" />

当表单完成时，这些操作将导致验证脚本运行。它可能不会固化您的验证脚本，因为可能还有其他一些东西需要简化，但这应该可以解决您当前遇到的问题。

PHP不能在。html文件上工作。

将action="index.html"更改为action="index.php"将index.html文件名改为"index.php"

工作。

这比你看到的更容易阅读。

        <div class="6u">
        <input type="text" name="name" placeholder="Name" value="'.$name.'/></div>
        <div class="6u">
        <input type="text" name="email" placeholder="Email" value="'.$mail.'"/></div>
        </div>
        <div class="row half">
        <div class="12u">
            <textarea name="message" placeholder="Message" rows="6">'.$comments.'</textarea></div>
        </div>
        <div class="row">
        <div class="12u"><ul class="actions">
        <li><input type="submit" name="submit" class="button" value="Send Message" /></li>
        </ul>
         </div>
        </div>
        </form>';
        } //end if ($completed == false)

如果你在echo中使用单引号，你就不需要做'.escaped from echo.'
