Do you render these two lines inside a valid html page? – Daxcode Commented Mar 27, 2012 at 12:39

Does the code you posted work? What happens when you run it? (There is a typo in the code, first of all. The string in the
alert()needs to be wrapped in quotes.) – David Commented Mar 27, 2012 at 12:39 - tough typo, haven't even seen it (credits should go to David! :)) – Daxcode Commented Mar 27, 2012 at 12:43

- @Daxcode: Of course, if the OP simply runs the code, an error message would point out the same thing :) – David Commented Mar 27, 2012 at 12:45

Reset to default 5You forgot to wrap string with quotes in alert .
"Your downlaod key is wrong, Please try again!" is a string
if(isset($_POST['downloadkey'])){
$key = $_POST['downloadkey'];
if($key != $data['download_key']){
echo 'Your key is wrong.';
echo '<script type="text/javascript"> alert("Your downlaod key is wrong, Please try again!");</script>';
}
}
You can do this by putting this alert into the onload of the body like so:
<body onload="alert('Your download key is wrong, Please try again!');">
...
</body>
