How about
if (($add + $remove + $view) > 1)
{
//error
}

Subject: [PHP] group comparision
i have a php script that has three variables that could be set to "1"
depending on the values of a form being sent to the .php file.
$add
$remove
$view
i need to do some error control in my script to make certain that one and
only one of these is set to "1". i am coming up with a very long
control structure:
if (($add="1") && ($remove="1") || ($add="1") && ($view="1") || etc...))
is there a shorter method to do this? and can i break this up onto
multiple lines to make my code a bit cleaner? can i do something like:
if (
($add="1") && ($remove="1") ||
($add="1") && ($view="1") ||
($remove="1") && ($view="1")
) {
Thanks! -Charles
