Increment name of Variable

[danosmanos]

Dear All,

I have a series of variables being sent from a form. I know that the variable names are going to be "amount1", "amount2" etc but I dont know which ones are set.

I need a way to increment the name of the variable (not the value) so I can do something like;

if(isset(amount1)){then do this....}

but I dont want to have to do this...

if(isset(amount1)){then do this....}
if(isset(amount2)){then do this....}
if(isset(amount3)){then do this....}...............

Please help!

you can drop all those values in an array like such:

$count = 0;

while ($POST["amount$count"]) != "") {
$Array[$count] = $POST["amount$count"];
$count++;
}

then you can just do:

foreach ($Array as $element) {
if (isset($element)) {
// then do this...
}
}

However, this only works well if you want to do the same thing to all the "amount" variables. If you need seperate code for each, you're probably better with the long list.
