First you will have to post it somewhere so for example purposes we'll say the form/checkboxes is located at http://example.com/admin/form

We will say you are submitting the form to : http://example.com/admin/save
In the admin controllers --> save method you will have to get the data from the $_POST once you have that is when you can check if you have three values of the same like so:

PHP Code:

$i = 0;
$vals =array();
foreach ($data as $key => $value) {

if (!in_array($value, $vals)) {
$vals[] = $value;
}
else {
$i++;
}
}

if ($i >= 3) {
return FALSE;
}
else {
return TRUE;
} 


Or you could use jQuery to not even let it get to that point.

Code:

<script type="text/javascript">
$('#my_form').submit(function(e) {
e.preventDefault();

$('input['type="checkbox"]').each(function() {
// check each input here
});

});

</script>

Thanks "egall8"..

and here is the scenario. take a look an image below as you reference. check-box value is PR No. which is, when i check different PR No. it will come false. else return true. how could i make it in php or in javascript....
