Undefined Variables

zbee

I have problems with undefines variables. I have this script that mails some info gotten from an html form. The form has a method that sends the info through the URL, but if I erase those parameters the php page gives an "Undefined Variable" error and shows the file location of the file. This is a major security issue on my server. My question is: how can I configure my server not to show that error or what else could I do? I've seen that kind of configuration in lycos but I don't know what to change in my php.ini file.
Help!

Have you got something like this:
form.html

<html>
<head>
<title>Form</title>
</head>
<body>
<form action="send.php3" method="post">
<input type="text" name="1"><br>
<input type="text" name="2"><br>
<input type="text" name="3"><br>
<input type="submit" value="SEND">
</form>
</body>
</html>

send.php3

<?php
$to = "webmaster@something.com";
$subject = "Form Details";
$message = "Someone used the form. They entered:\n".$_POST['1']."\n".$_POST['2']."\n".$_POST['3'];
$from = "From:www.mysite.com<Mysite>";

echo "Message Sent";

mail ($to,$subject,$message,$from);

?>

Yes, my code is similar to that. But I don't care if the method is Post or Get, my problem is when someone might see the page php page without going to the form first. If that happens, all the variables are undefined and it shows an "Undefined Varible" error and the location of the file. I either want to change my configuration so I don't see the file's location or an if statement so it displays another message in case there are any undefined varibles. I've seen that kind of code in Cold Fusion and I was wondering if there's something similar in PHP.

Try doing a check at the beggining or your page to say "if this doesn't exist, go back to the form.

<?
if(empty($_POST['var'])) {
   header("Location: form.php");
}

Thank you so much, man! You have saved my life (and my job). I will be eternally thankful.

Well, I dunno about eternally.....a few years of thankfulness will suffice 😃
