Verifying a password in php

cloud_trifle

So here's the setup:

I have 2 scripts, the index and authorise.php

Index:

<html>
<head> <title>Testing</title>
</head>

<body>
<form method=post action=authorise.php>

Password: <input type=text name=authpass size=20>

<input type=submit>

</form>

</body>
</html>

and Authorise:

php
$the_auth_pass = "itsybitsy";

$submitted_pass = $_POST ('authpass');

If ($the_auth_pass == $submitted_pass)
(
echo "Well Done. The password you entered is correct.";
)
else
(
echo "The password you have entered is incorrect.";
)

?>

The problem is, it's returning a blank screen. Im completely new to this, and I do tend to run before I can walk. Any help appreciated.

I know I should probably be using SQL to store passwords and things, but this is my first day of learning, I havent gotten that far yet 😉.

Welcome to the fun world of PHP! 😉

There are a few minor issues with your code, this should work:

index.php:

<html>
<head><title>Testing</title></head>
<body> 

<form method="post" action="authorise.php">
Password: <input type="text" name="authpass" size="20" />
<input type="submit" />
</form>

</body>
</html>

authorise.php:

<?php
$the_auth_pass = "itsybitsy";
$submitted_pass = $_POST['authpass'];

if ($the_auth_pass == $submitted_pass) {
   echo "Well Done. The password you entered is correct.";
} else {
   echo "The password you have entered is incorrect.";
}
?>

Happy learning. 🙂

Thank you very much.

I can't believe I missed somethings that were so simple. Some php grammar is in order!

Sorry for the double post/bump, but I wasn't able to test this when I replied last time...

It still appears to be giving me just a blank page, and no echo 🙁.

:bemused: Well, I ran that code on my machine and it seems to work fine. Did you make any changes to the code, and what server setup are you using?
