Counting for 1 ++

Iv got a really stupid problem, iv created a dynamic form, where the inputs can be added / removed by the user.
However i need to name each input uniquely, I.E textbox1, textbox2, textbox3 on and on...

The code i have for generating the textbox is this;

Code:

$form = new build_form;
	foreach($_SESSION['form'] as $element){
		if(strlen($element) > 0){
			$form->$element('', 'name');
		}
	}

basicly its getting the elements and functions from my class, it works perfect, i just need a way to name with a number at the end, which will go up 1 for every input added.

How to do this? I managed to get it so it was putting in 2 textboxes ( when it should only be doing 1 ) and was naming them name1, name2 but then the next two that came in where also name1 and name2

Can't you just give them a name of name1[] and name2[], then they'll simply get passed through as an array instead. Makes it much easier on both the Javascript and PHP side that way.

PHP Code:


			
foreach($_SESSION['form'] as $i=>$element){
    $id = 'name_'.$i;
}
