basic question

lobotomized

howdy, i am just learning php, i got a book and have been going through the examples so far everything was going great.
i have come across a problem though.
this is very basic of course. i created a html page with a simple text field and submit button. its supposed to link to a php page that will simply display welcome: (username). thats it. i get an error message saying:
Notice: Undefined variable: user in C:\Xitami\webpages\php\ex9.php on line 10

well, here is the code from the html page:

here is the php:

<body>
<?php
print "<b>welcome $user</b><p>\n\n";
?>
</body>

pretty basic, which is why im so aggravated at not being able to get this to work.

when the php page loads i can see in the url address field that it is receiving the 'user' variable.

http://localhost/php/ex9.php?user=joe

thanks to anybody that can help point me in the right direction.

it has to do with register_globals setting in PHP

try this:

instead of just accessing:
$user

try:

$_GET['user'];

or
$HTTP_GET_VARS['user'];

_SuperString

lobo may be right... you need to edit the file php.ini, thats were the PHP configuration is.
you could try running phpinfo(); in a page to see your current config.

hi-liter

depending on your register_globals setting in php.ini, which on new versions of php is set to OFF, as it should be for security reasons, the issue is probably due to this.

this post here, has full working form with globals = off, though it utilizes one page, vs. two, but that can be changed easily enough, if necessary.

my input:
change this:
<form action="ex9.php" method="POST">

and you may want to change this
it may work better.
print "<b>welcome ".$user."</b><p>\n\n";

How about:

<?
if (!$submit){
echo"
<form action=$PHP_SELF method=POST>
<input type="text" name="user">
<br>
<input type="submit" value="push me">
</form>";
}

else{
if ($submit=""){
echo "Please Go back and fill in ALL information";
}
else{
print "<b>welcome ".$user."</b><p>\n\n";
}
}
?>

hi fellas,

well you guys were right about the register_globals thing, i did alter this in php.ini and the little script works now.

thanks a lot for your help. i know that this is some kind of security hazard to do this, but i dont care as i am just doing this to learn a little php on the side.

i know ill probably be back here a couple hundred times so see you guys in the forums😃
