通过out.php发送邮件以跟踪按钮的点击次数

Question

I need to track a button every time someone clicks on it. I created a file "out.php" to send me an email and redirect to a link outside my page. This code redirects but the mail doesn't send.

<div class="buyprod">
<a target="_blank" href="http://xxx.com/out.php?url=<?php echo urlencode($this->product['from'])?>">
<img src="http://xxx.com/buybtn.jpg" alt="buy"/>
</a>
</div>  

out.php

<?php
$url = urldecode($_GET['url']);
header("Location: ".$url);
$message = "Someone clicked buy: ";
$link = $this->product['from'];
mail('[e-mail]', '@Buy', $message.$link);
exit;

Anyone knows what's wrong with this code? Thanks in advance!

Answer 1

You are calling a class $this->product['from'] that does not exist in out.php. This will make your file error out. Also, you need to set a 'From:' header when using mail(). see stackoverflow.com/questions/6988051/php-mail-function-headers#6988085

Change out.php to -

<?php
$url = urldecode($_GET['url']);
$message = "Someone clicked buy: ";
$link = $_GET['url'];
mail('[e-mail]', '@Buy', $message.$link, 'From: [e-mail]');
header("Location: ".$url);
exit;
?>
