PHP Help Needed!!!
 

I am just playing with PHP with different webservers (IIS and Apache)
Running into one interesting probelm, I can't get html forms to pass variables into php script. Can anyone tell me if I did something wrong with the conf or ini files?

HTML:
<form method="POST" action="example18.php3">
<div align="left">

<font face="BankGothic Md BT">Admin password?</font>
<input type="password" name="pw" size="14"><input type="submit" value="Submit"></p>
</div></form>

PHP:
<?
$adminpass = "test123";
if ($pw == $adminpass)
{
print("Welcome to the administration area!");
}
else
{
print("Wrong password");
}
?>

When I run the html and submit it tells me undefined variable pw.

Anyone know why?

Really?? No one?

just a random guess, try:
if($_POST['pw'] == $adminpass)

if it works I can explain what is it you're doing wrong ...

GREAT!!!!!! IT WORKS!!!!!!!! Thanx for the big help Overmind.

What did I do wrong exactly??..I was just copying and pasting the example on the webpage. :?:

well you had nothing declaring where $pw was coming from in what you posted first of all ;)

ahhhhhh.................stupid website.....stupid me........
thx guys, always get what I needed to know here.

well, that is the way PHP used to work by default settings... you could access http request parameters this way... very dangerous & stupid. Caused lots of tears and confusion to some "l33t hax0r PHP coders" :lol: either when their sites were being hacked or when this "feature" got disabled by default.

5vz-fe: it looks like you've been very unluky picking up the web site to learn from :|. Anyways for what you've been doing wrong read this: http://www.php.net/register_globals. Also reading through their PHP Manual is highly recommended (I know it's huge and long :shock:, but I'm unaware of any better source :().

hahha well maybe, but damned if you'll see one of my servers ever running with register globals = On , even if it does mean that many of the pre coded things like commerce stores etc wont work.. just have to search harder for well coded scripts :)

Overmind, you are totally right, you cannot believe how much trobule that stupid webpage brought me. I keep changing the php.ini script thinking that I have set the variables wrong or something. I even wipe the Apache server clean and try the IIS server instead...and still the same results...that's y I turn to u guys. <sigh>
