Calculate sum

[thomo03]

Hi there,

 

I've recently started programming with PHP, read a few tutorials, and manage to send info, like on a shop. A user clicks an item, and they are told they have ordered that item. The one thing I can't do is, say somebody orders an item which take 3 hours to make, yet another person makes an order, but that also takes 3 hours to make. The problem is, for that customer they are 2nd in line, so it will actually take 6 hours to make.

 

Is this simple enough, or does it take a lot to intergrate?! Does anybody have examples?

 

Thanks.

The code logic is actually quite complex, but is basically the logic used by project management software. It isn't quite as simple as 3+3 = 6, because the people who make these items aren't going to be working 24 hrs a day, it may be possible for one person to make two items at the same time, etc
