Hi Dave,
try this:
input name="Grid1[1]" type"checkbox" file://1st grid, 1st checkbox
input name="Grid1[2]" type"checkbox" file://1st grid, 2nd checkbox...
Pay attention to the indices in Grid1[1], Grid1[2].
After submit you will receive $_POST['Grid1'] as an ARRAY containing all
indices of the checked checkboxes. Then loop through it and do what ever you
want:
foreach ($_POST['Grid1'] as $value) {
echo $value;
}
