Form Variables

[wilzy]

I know this is a simple problem... but can someone help me the trees for the forest.

I have a form and page which processes that form

The form being "login.php"

<form method="post" action="process_login.php">

Username: <input type="text" size="20" name="username"> <p>
Password: <input type="text" size="20" name="password"> <p>

<input type="submit" name="submit">

</form>

And the part in the 'process_login.php'

$local_un = $POST[username];
$local_pw = $POST[password];

print($local_un . " is the username and " . $local_pw . " is the password");

All im trying to do is collect the form variables and put display them in process_login.php

What am i overseeing?

Your help is greatly appreciated!

$POST[username] is not very nice, it's better to put 'username' in quotes. Still it should work, only generating a warning.
The rest seems more or less OK to me. Maybe you're running PHP3, where $POST doesn't exist? 🙂

PS This line looks funny:
$local_un . " is the username and " . $local_pw . " is the password"

Why use double-quotes with concatenation? You'd better make it

"$local_un is the username and $local_pw is the password"
(maybe you'll need {} because of underscores, i'm not sure),

or this way:
$local_un . ' is the username and ' . $local_pw . ' is the password'

There is nothing wrong with your code. Remember that $_POST is only available in php version 4.1.x

Put the following in process_login.php to see what the post is sending you....

print '<pre>';
print_r($_POST);  // php >= 4.1
print '</pre>';

print '<pre>';
print_r($HTTP_POST_VARS); // php < 4.1
print '</pre>';

Two things:
You might want to chage the password field to type="password" and secondly in many versions of PHP (mine anyway) you can directly use the $username and $password. Good Luck.

FYI: that's not about versions, that's about configuration (register_globals on/off)
