I'm trying really hard to figure out how to solve this problem. Please be gentle, i'm still learning!
There are four workplaces named: B.Avf, R.Avf, Office and Production. Products is passing theese workplaces. Now i'm building a script that can alert if the same product is passing the same workplace twice. Now, this is the hard part: If the product has passed "B.Avf" it can't pass "R.Avf" whitout an alert, same if the product has passed "R.Avf" it can't pass "B.Avf" whitout and alert. But if the product has passed for ex. "R.Avf" it´s ok to pass "Office" whitout an alert.
This is what i got so far: (It's like example number 5 =)
Maby should i create nested if
statements instead?
This code will turn true all times!
PHP
if($_SESSION['user']['usr_workplace'] == "R.Avf" ||
$_SESSION['user']['usr_workplace'] == "B.Avf" &&
strpos($history, "R.Avf") !== FALSE ||
strpos($history, "B.Avf") !== FALSE)
