if the checkboxes are not checked they wont appear in the $_POST superglobal.
Try to print your post data like print_r($_POST) and you would know the reason.

A suggestion: this does not solve the problem if the client disables javascript. The suggestion of network18 is correct, in your server side you should check if the index key exists. So instead of:

if($_POST['wdays1']=='')
    echo $wdays1v = 0;
else
    echo $wdays1v = 1;

It should be:

# default
$wdays1v = 0;

# if exists
if(array_key_exists('wdays1', $_POST))
{
    # and if it is not empty
    if( ! empty($_POST['wdays1'])
    {
        $wdays1v = 1;
    }
}
