I can't understand what you're trying to do in your loop, nor exactly what you're trying to do from your explanation...You're going to have to at least be a bit more clear in what you're trying to do...

 

if you have a url like say

 

http://www.blah.com/index.php?stone=4

 

you can access that stone variable like so:

 

// this will print 4 on the screen
echo $_GET['stone'];

this is what i have in my url

 

http://www.????????.com/order.php?snum=3&stone1=diamond&stone2=ruby&stone3=emerald

 

.....meaning i have a max of 3 stones

stone1 2 3 etc or however many stones they choose from the page before will show up as = snum

i want to have $stone1= GET_['stone1'] within the php so that i can use $stone(watever number it is) later on in my php page. i was just trying to use a loop to get and state the variable within my php code

hmm...okay I'm still not really understanding what exactly your problem is...if you know ahead of time what your $_GET variables are, simply assign them to normal variables:

 

$snum = $_GET['snum'];
$stone1 = $_GET['stone1'];
$stone2 = $_GET['stone2'];
$stone3 = $_GET['stone3'];

 

or you could do a loop like this:

<?php

foreach($_GET as $key => $var) {
   $$key = $var;
}

echo $stone1;
?>

ok thanks that helped. i just used your for each code.

 

i just didn't want to write all that code to get value from the url, cause there might be alot in the future i would not want to update my code all the time. but this way is much faster and writes the code according to what the user input in the previous form.  haha thanks for your help. i know you probably didn't get what i'm saying but your help is much appreciated. everything works thanks again

Wait wait wait.

You're using a form?  Why in the world would you use GET then?  Use POST and make the element an array.

True, but the principle is still the same. just change it from $_GET to $_POST

Not if he makes the elements on the form into an array.  It simplifies things a lot.
