Re: [Nolug] PHP $_POST problem

I don't think my last reply went through, so I'm sending again.

Instead of using $variable as the key into $_POST, you really need to
use name as a string, like so:

$variable = $_POST["variable"];

Otherwise, PHP looks into the value of $variable (which is nothing,
at that moment), and uses that as the key into $_POST, finding
nothing there.

In your source, change line 13 from

$materials["quantity"][1] = $_POST[$materials]["quantity"][1];

to:

$materials["quantity"][1] = $_POST["materials"]["quantity"][1];

Hope this helps,
Kevin
