Well, you could use an array for the checkboxes. It works very easy.
So, instead of this: name='formCheck1' and the others, use an array.
Something like this: name='formCheck' This creates an array of checkboxes...
What this does is each checkbox will be added to this array. So, formCheck1 will really be formCheck...
So, to count them you can just check them in a loop like this:
$checkCount = count($_POST['formCheck'];
Remember the formCheck is now an array. All CHECKED boxes are in it. All UNCHECKED boxes are NOT in it.
SO, the count is just however many boxes have been checked.
You can still use them individually if needed with $somevariable = $_POST['formCheck'];
(But, why would you?) Lastly, you can use a FOR or FOREACH loop and parse thru them if needed...
Hope that helps! Good luck..
