multiple multiple select boxes dynamically created.

[justride]

I have a for which the user can add multiple fields dynamically, which allows them to expand for more entries.

most of the data is singgle values except one field which is a multiple select field.

so if the user wants 5 multiple select fields my html looks like

<select name="requirements[]" multiple size=10>
..
<select name="requirements[]" multiple size=10>
..
<select name="requirements[]" multiple size=10>
..
<select name="requirements[]" multiple size=10>
..
<select name="requirements[]" multiple size=10>

However the problem is then when the form is submitted, all the data is stored into one array instead of a 2 dimesnional array with data from each select in its own array.

	$requirements[] = $_POST['requirements[]'];

It's impossible to keep track of which data comes from which select box.

Any suggestions?

Thanks
Chris

I figured it out the html selects need to be like this..
where $i changes
<select name="requirements[$i]" multiple size=10>

$requirements[][] = $_POST['requirements[][]'];

I have to keep track of $i in a hidden field.

you can also use checkbox if a user is allowed to select more values of the same field
