This is a bit of a tricky one to explain but I've never come across this before so I've got no idea how to properly approach it. I'm writing a web app that when a form is submitted, it takes two values, the current value and the submitted value.
When the form is submitted, it checks that the new value is not the same as the current value. If that is true, then go through the rest of the process. This is so I'm not updating the database with values that already exist in there.
Problem is I have an assigned to select box. One of the options is unassigned which has a value of 0. But in the following if statement, zero is not treated as a proper value and thus fails the check.
( $newtaskassignee != $taskassignid ) { ... do something ... }
So when $newtaskassignee
is 0, the following if statement should be true and carry on what is inside the immediate curly brackets.
However in this statement, zero is ignored and doesn't pass the check. How can I change this so it accepts numbers from 1 to 9 including 0. This checks user IDs so they could be anything so I can't select a range as it increments by 1 per user obviously.
