i have a while function that increases $i by one each time ($i++ while this function is still going it populates areas inside of a <input> html tag like so <input type="text" value="" name="try'.$i.'" /> it does this for X amount of times. Now the user press submit after filling in all the information. the page then refreshes on its self and is suppost to input the X amount of items selected. X is determinded by what ever the user puts in to the field before this. What I can'T figure out is how to make it so that the users can have 100's of box yet i dont have to code the php 1 insert at a time

I have been looking for the answer for the last week and this is the best example i have came up with so far but its not quite it.

<?php
$foobar = "blah blah";
$a = "foo";
$b = "bar";
$fooboo = "$a" . "$b";

$fooboo = $$fooboo;

echo $fooboo;

?>

It does partly what i want it to do make 2 vars into one but in stead i need to make it so i can have a set name such as HELLO and have the "$i" be put on the end then the whole word turned into a var......

I=4

Hello=>Hello$i=>$Hello4

The area with the big blanks is the part im stuck on.......

Whilst you could carry on with your current method, i suggest you use arrays. Since your code is long, ill just give a quick example:

<?php
if(isset($_POST['submit'])){
foreach($_POST['qty'] as $k => $v){
 	if(ctype_digit($v) && $v > 0){
		echo 'The customer ordered '.$v.' units of the product with ID: '.$k.'<br />';
	}
}
}
?>
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
<?php
for($i=0;$i<5;$i++){
echo 'Quantity of product '.$i.' <input type="text" name="qty['.$i.']" /><br />';
}
?>
<input type="submit" name="submit" value="Submit" />
</form>

Take a look at how that works. Once you understand that, rewrite your current stuff to make use of arrays - it's much easier.
