Assigning a variable in PHP by address bar

ChrisCh

Hey there. I'm trying to assign a variable to something from an address bar. What I was thinking was something like this:

hexkid

kawkazEE

you can use $_GET...

example:

filename.php?id=1234

in my example the value(1234) will be stored in $_GET["id"], you can directly retrieve it or passed its value to a variable and call the value of the variable..

$pass_it_to_me = $_GET["id"]

this sure works... now to display the value be sure to check that the variable actually has been passed a value..

if (isset($pass_it_to_me)) {
echo $pass_it_to_me;
} else {
echo "No value passed.";
}

hope this helps...

Wow thanks hexkid Smile

I'll try it as soon as the server works again...

Thanks also for your help kawkazEE, but hexkid's code already used $_GET - just less complex Smile

Alias

you could use the $_GET method just like this,

Heya. Thanks for helping manum, but as I mentioned above, I've already got it all setup and working to my satisfaction Smile

Thanks for your input though Smile

If register_globals is on, you can just use $id for something like index.php?id=245, $id will be 245. However, I'm not sure if register_globals is on or off here.
