Multi-dimensional array prob

[Anon]

Hello,

I'm have a form which includes a dynamic number of items. It has a check box which holds the row ID number, and a hidden field (Type) to specify what type of row it is these are stored as arrays.

The data displayed is from 2 different tables, that's what the Type field is used for.

Because when only some items are checked, the checkbox array has a limited number of values, but the hidden field array always has the maximum number of values.

EXAMPLE:
Let's say there are 4 items, and all 4 are checked. It would return something like this:

ID Type
44 2
98 1
32 1
81 2

If only the first and last items are checked, then it returns this:

ID Type
44 2
81 1

Please help.

use checkboxnames like "name[2]" that is, with a number in the index.
That way, you can sync the hidden data with the checkbox data through the index.
Unchecked fields will just be 'unset' elements in the array, all checked boxes will appear in their proper locations.
