Needs to be changed to the following if your forms are using the GET
HTTP method:
if(!isset($_GET["var"])){
// do nothing
}else{
// VAR IS SET.. DO SOMETHING
}
If your forms use the POST HTTP method then it needs to be changed to:
if(!isset($_POST["var"])){
// do nothing
}else{
// VAR IS SET.. DO SOMETHING
}

Are you accessing these variables through $var or $_GET["var"]?
I am accessing them as $var.
Example (from memory)
if(!isset($var)){
// do nothing
}else{
// VAR IS SET.. DO SOMETHING
}
Real basic stuff, but if I echo out the value so I see if it matches
what I see in the above URL I get...
(SAMPLE URL) blah/my_url.php?submit=submit
(SAMPLE CODE) <? echo "Submit = ".$submit ?>
(SAMPLE RESULTS) Submit =
Thanks gang!
I have never needed to use $_GET["var"]
What is the main difference?
Would this be a setting difference between a WIN setup of PHP and a
Linux setu of PHP?
