Question

到目前为止，我有基本的文字输入。

 <form name="contact" method="post" action="contact.php">
<div id="subscribe">
    <input type="text" placeholder="Enter your email address...">
    <input type="submit" value="Submit">
    <div class="clear"></div>
</div>

这是我的“即将推出”登录页面的代码。我想知道的是如何将输入的电子邮件发送到某个地方供我访问。我尝试过添加PHP，但是我失败了（我是网络开发的网络）。

这是我正在尝试使用的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 "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['email']) ||
   died('We are sorry, but there appears to be a problem with the form you submitted.');       
}

$email_from = $_POST['email']; // 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)) {
$error_message .= 'The Email Address you entered does not appear to be valid.<br />';
  }
  if(strlen($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);
}

$email_message .= "Email: ".clean_string($email_from)."\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);  
   ?>
   <?php
    }
     ?>

任何时候我都尝试没有任何反应。如果您知道更短的方式，请告诉我或其他方式。谢谢！

Answer 1

嗯，最明显的问题是你的整个脚本测试不适合你的形式的POST可修改。对你的HTMl做这个改变，我打赌它有效。

<input type="text" name="email" placeholder="Enter your email address...">

EDIT 为了澄清这一点，$_POST是一个填充了您提交的表单字段的数组。因此$_POST['email']要求您提交一个名为email的字段的表单。没有字段名称，没有简单的方法来引用它

人们在说什么：

//<form method="post"> 
// Why do you have two form starts? Get rid.


<form name="contact" method="post" action="contact.php"> 
    <div id="subscribe"> 
        // you have to give the INPUT a name attribute. 
        // If you want to access the data using $_POST['email'], 
        // then you have to name it 'email'
        <input name="email" type="text" placeholder="Enter your email address...">
        <input type="submit" value="Submit"> 
        <div class="clear"></div> 
    </div> 
</form>
