  Hi,

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

  Thanks,

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

  use CGI.pm
  
  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.

  Hi,

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

  My code is:

  <perl>
  use CGI.pm
  my $cgiq = new CGI;
  if ($cgiq->param('stnop')==null) {
  ...
  }
  </perl>
  
  
  
  
  
  

  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>
  <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">
  </p>
  </form>
  
  
  
  
  
  
  
  
  
  
  
  

  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?
