Dynamically diplaying form fields after selectuing data from drop down

Hi All,

I have a problem and hope I can get the better solution from here.

I have a form written in HTML and I need to write that in perl so the main problem I am facing is that I need to generate some fields according the data I will select from the drop down list so basically I have drop down list which will ask for the number of students information I want to enter and after selecting a value from the number of students drop down it suppose to display that much set of First name, Last name, Phone number etc. So how can I post back the data to the same form in PERL script I can't able to know. I know we can do in Java but for PERL I do not know. So please help me I will be grateful to you all. I will be waiting for the replies.

Thanks,
Chittaranjan :)

Basically you can do something like this:

Expand|Select|Wrap|Line Numbers

 use CGI;

my $cgi = CGI->new;
 
print $cgi->header;

print qq|<form method="post">\n|;
 
if ( $cgi->param('number') ) {
 
    for ( 1 .. $cgi->param('number') ) {

        print <<REC;

<p>First name $_:<br><input name="first_$_">

<p>Last name $_:<br><input name="last_$_">

<p>Phone number $_:<br><input name="phone_$_">

<hr>

REC

    }
 
} else {
 
    print <<NUM;

<p>Select number of records:<br>

<select name="number">

<option selected>1</option>

<option>2</option>

<option>3</option>

<option>4</option>

<option>5</option>

</select>

NUM
 
}
 
print qq|<p><input type="submit">\n</form>\n|;
