hidden field-
Where's this form going and why does it need a multidimensional array to be passed as part of the form?
How you're going to do this depends on whether you control the page receiving the form. If you do, you have a couple options:
1) Serialize the array to a string with PHP's serialize function, then unserialize $_POST['order'] to get the original array back
2) Pass it through an array of form fields you'll have to generate
If you don't control the form then whatever you're submitting to probably expects something specific in hdnOrder... what is it?
