Get values from multiple checkboxes

halex

I have a multiple table rows and in each row is one checkbox. When I click Submit I need to recognize which one are checked.
So I will go through one loop and examine all checkboxes.
The problem is how to get the name of checkbox because name of my checkboxes are check1,check2,check3,....,checkn

So I need something like this in my loop...

for ($i = 1; $i < $tableSize; $i++) {
  if ( isset( $("check".$i) ) ) { // IS THIS GOOD?
     //then it is checked
  }
   else {
     //than it is not checked
   }
}

Question:
How to recognize element with dynamic name?
Is it good $("check".$i) where $i is loop counter and
my valid element names are check1,check2,check3...?

heres a different approach,

did you know that you can use one name and treat it like an array

for example

//when submitting only the ones that are checked will be in the array :)
$input_check_box = '<input type="checkbox" name="checked[]" value="values">';

Hope this helps

Here is the example:

<?php
if ($click) {
	for ($i = 0; $i < count($check); $i++) {
		if (isset($check[$i])) {
			print $check[$i]."<br>";
		}
	}
}
?>
