passing array from form to form

bmcc has asked for the wisdom of the Perl Monks concerning the following question:

In the following test2.html code user does multiple selection. When Submit is pushed,the selections are passed correctly to an array in test2.pl. (e.g. cis100cis200) However, if I pass this array in test2.pl to test3.pl as a hidden filed as a hidden field, only the first entry out of the selection is received by the array in test3.pl. (e.g. cis100) I wonder why and how to fix this problem ? Thanks.

file name: test2.html
<html>
<body>
<form name="form1" method="post" action="/cgi-bin/test2.pl">
 
          <select name="class" size="4" multiple>
            <option value="cis100">CIS100</option>
            <option value="cis200">CIS200</option>
            <option value="cis300">CIS300</option>
            <option value="cis600">CIS600</option>
            <option value="cis700">CIS700</option>
          </select>
        <input type="submit" name="submit" value="Submit">
</form>
</body>


#file name: test2.pl
use CGI qw(:standard);
print "Content-type:text/html\n\n";
@class= param('class');
print "<html><body>";
foreach $a (@class)
 {
  print "$a<br>";
 };
print <<EndForm;
<form name="test3" method="post" action="/cgi-bin/test3.pl">
<input type="submit" name="submit" value="Submit">
<input type="hidden" name=class value =@class>
</form>
EndForm
print "</body></html>";

#file name: test3.pl
use CGI qw(:standard);
print "Content-type:text/html\n\n";
@class= param('class');
print "<html><body>";
foreach $a (@class)
 {
  print "$a<br>";
 };
print "</body></html>";

`<input type="hidden" name=class value =@class>` [download] That's broken. You want this instead: `print hidden('class', @class);` [download] -- Randal L. Schwartz, Perl hacker	[reply] [d/l] [select]
