Multiple Selects and Technique Questions

[Anon]

I have a couple of questions.

First, how do I get all selections from a multiple select box? When I check the variable after submission, it only contains the last one that was selected in heirarchial order. I also use sizeof() hoping it will be an array. Any ideas?

Second is more of a technique question. I have a table with one of the columns being a bunch of checkboxes and named them using a counter variable such as: delete_0, delete_1, etc... If I did this, how would I accesss the data from these checkboxes (or any form object)? This isn't a problem as long as the list will always be the same length, but it is of arbitrary length by reading the data out of a dynamic file. I thought maybe if I named the checkboxes the same thing, I would be able to get an array back. Any thoughts?

Thanks in advance. :-)

Your second question is very near your first. Here is an example of using an array. Name your checkboxes all the same i.e. name=NUM[]

then on your response page.

$x = count($NUM);
echo $x." Boxes Selected";

while (list($key, $value) = each($NUM)) {
$query = "select * from Table where NUM = '$value'";

Look at your URL when you submit on a select multiple. It will reveal more on how to juggle things.
