Verify if checkboxes are checked?

[lindm]

I have 6 checkboxes. Is there an easy way to check if any 2 of them or more are checked?

 

if (2 or more checkboxes are checked) return xxx;

 

Thanks

Yes ... but exact details depend on your form code.  If the checkboxes are named as array elements, you can check the size of the array retrieved from the $_POST/$_GET array for the checkbox variable

When checkboxes are checked your browser will include it in the $_POST data (or $_GET date depending on your forms submit method).

 

So just check to make your checkbox field exists eg:

 

if(isset($_POST['chk_box_name']) && !empty($_POST['chk_box_name']))
{
    echo 'chk_box_name was checked!';
}
