Multiple Selections in Drop Down List Boxes

[Big_Perm]

From an HTML form where multiple selections are made in a list box, how can the data be processed for each selection?

Hi Big_Perm (I love the username) - welcome to Webmasterworld.

In perl, using the CGI.pm module, you'd use something like

use CGI;
$query=CGI::new();
@values=$query->param("name_of_select");

This would put the multiple values into the array @values, and you can take it from there.

In PHP, I don't know - I'm assuming that the values will automatically be put into an array instead of a string, but I've never tried it. Anyone?

(welcome to the board)

What language is going to receive the form values?

If perl, SugarKanes way will work, or this is an alternative:

read(STDIN, $buffer, $ENV{'CONTENT_LENGTH'});
if (length($buffer) < 3) {
$buffer = $ENV{QUERY_STRING};
}
@pairs = split(/&/, $buffer);

foreach $pair (@pairs) {
($name, $value) = split(/=/, $pair);
$value =~ tr/+/ /;
$name =~ tr/+/ /;
$value =~ s/%([a-fA-F0-9][a-fA-F0-9])/pack("C", hex($1))/eg;
$name =~ s/%([a-fA-F0-9][a-fA-F0-9])/pack("C", hex($1))/eg;
$value =~ s/\r//g;
$FORM{$name} = $value;

$o .="<br> Form name : <b>$name</b> Value : <b> $value </b>\n" if $debug>3;
}

Then all your form values are in %FORM{'name'}

Actually i'm using VBScript. Can it be done in VBScript or possibly JavaScript? Thanks.

A quick example in asp:

Incoming form field name is "test", it's a multi select box. Variable "item" is just a handy descriptive variable to hold the value.

<%
for each item in request.form("test")
response.write("My value is: " & item & "<br />")
next
%>
