Problems after PHP update

I've updated my PHP installation on my server, but now most of my PHP scripts don't work anymore. For example, I have a login form like this:

Code:

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

Username: <input type="text" name="username" /><br />

Password: <input type="password" name="password" /><br />

<input type="submit" name="submit" value="Login" />

</form>

Now, if I do a

PHP Code:


		
			
echo $username;

in login.php, it shows nothing... :confused:

It might have done something to your global variables. Try

Code:

echo $_POST[username]

does that work?

I think it's because register_globals went from on to off in your new PHP version. This is explained here: http://de3.php.net/manual/en/languag...predefined.php

So you have to change your scripts (e.g. use $_POST['id'] instead of $id) or change register_globals to on in your php.ini (don't forget to restart Apache then).

Thanks Joe and Falko! That helped a lot! :) :)

I set register_globals to on now in my php.ini, and my scripts are working again.

Glad it's working :)

I would recommend using $_POST and $_GET rather than just plain $username. Keeps things more secure so an incident doesn't happen involving $password from GET instead of POST.

Right, but I'm rather lazy... :D
