Yes. The way I normally do this is to use HTML that looks something
like:
select multiple='multiple' name='test[]'
option value='1'Red/option
option value='2'Green/option
option value='3'Blue/option
/select
Now in your PHP program, you can access them all with something like:
?php
foreach($_POST['test'] as $test) {
echo You selected $testbr /\n;
}
?

Re: [PHP] Drop Down Box Question
Hello,
Is there a way to handle data gathered from a drop down menu that
allows
multiple selections using PHP?
Of course. Name your select box as an array, and include the 'multiple'
keyword.
select name='something[]' multiple
Then you'll have an array on your processing page that holds all of the
values that were selected. $_POST['something'][]. Note that it starts at
zero.
You can use count($_POST['something']) to see how many were selected,
etc...
If you need specific IDs or something from the OPTIONs presented, other than
the text between the tags, you can even use the VALUE= attribute to pass
around data so that $_POST['something'] doesn't just start at 0 and count
up:
?php
while (list($id, $name) = each($ineeddatacaptain)){
echo $id: $nameBR\n;
}
?
SELECT NAME=ineeddatacaptain[] MULTIPLE SIZE=5
OPTION VALUE=1Captain Kirk/OPTION
OPTION VALUE=2Spock/OPTION
OPTION VALUE=3McCoy/OPTION
OPTION VALUE=4Scotty/OPTION
OPTION VALUE=5Sulu/OPTION
OPTION VALUE=6Uhura/OPTION
OPTION VALUE=7Chekov/OPTION
/SELECT
If you click on Spock, instead of just 0, Spock, you'll get 2, Spock -- You
get his ID number as well as his name.
This is extremely convenient. And you sure can't do that in ASP easily :-)

That's confusing. There's no way to get Spock from the code. You only
get the number in the value attribute. If the user were to choose Spock
and McCoy, then you'd have:
$_POST['ineeddatacaptain'][0] -- 2
$_POST['ineeddatacaptain'][1] -- 4
It's up to the programmer to associate 2 with Spock, and 4 with McCoy.
