Read POST form data

  • 15 years ago


    How do I read data from POST form fields that have been passed to my web page?

    The easiest way is to use This will parse the POST data and provide a hash containing the data, named by the parameter:


    my $cgiq = new CGI;
    print $cgiq->param('test');

    Would work whether "test" was passed by a POST or a GET. There is another member that you can use to determine whether this is a POST request should you need to differentiate.

    Thanks for the quick reply, but I get an error.

    My code is:

    my $cgiq = new CGI;
    if ($cgiq->param('stnop')==null) {

    And my form is:

    <form action="(the URL that contains above code)" method="POST" enctype="application/x-www-form-urlencoded">
    Please type your Beta Key into the space below:<BR>
    <input type=text name="bkey=" maxlength=29 size=45><BR>
    <font face=arial size=2>
    You can find this key in your beta invitation email. It is in the format xxxxx-xxxxx-xxxxx-xxxxx-xxxxx.
    <input type=hidden name="stnop" value="1"><BR><BR>
    <p align=right>
    <input type=submit value="      < Back      " name="bkbtn" disabled>
    <input type=submit value="      Cancel      " name="canc" disabled>
    <input type=submit value="      Next >      " name="go">

    And I receive this error:

    [ Error: Perl error in :
    syntax error at (eval 1993) line 2, near "use CGI." ]

    I am very new to Perl, can anyone explain this one?
