[PHP] register_globals off issues
I'm very new to PHP/mySQL and am working through the PHP and mySQL for
Dummies examples. Unfortunately, these were all written with
register_globals on and the system I'm using has register_globals off.
I'm having trouble converting the examples to use the $_POST() expression.
Specifically, the examples use a POST with a form variable to run a
query and then unset this variable as such:
if (@$form == yes)
{
unset($form);
}
I'm trying to convert this to use $_POST() as such:
if (@$_POST['form'] == yes)
{
unset($_POST['form']);
}
However, this does not work. It appears that you can't unset the
$_POST['form'] array element.
Does anyone have any suggestions on how to fix this?
I know I'm probably missing a few very obvious things here... but I am a
newbie.

unset() works for any variable - also for the superglobals like $_POST.
Try this:
[cut here]
xmp
?php
print_r($_POST);
echo 'F1 = ', $_POST['f1'], \nF2 = , $_POST['f2'], \n;
unset($_POST['f2']);
print_r($_POST);
?
/xmp
form method=POST
input type=text name=f1 value=?php echo $_POST['f1'];?
br
input type=text name=f2 value=?php echo $_POST['f2'];?
br
input type=submit
/form
[/cut here]
What error do you get? Make sure you're using the correct case - PHP is
case sensitive in variable names and associative index keys...
