Why the html part does not print in this perl script?

**tony007** · Jul 19th, 2005, 05:50 PM

Hi guys i try to run this script but i get this error :

Code:

CGI Error
The specified CGI application misbehaved by not returning a complete set of HTTP headers. The headers it did return are:


Undefined subroutine &main::HTMLGetRequest called at c:\inetpub\wwwroot\cgi-bin\jukebox2006\textchat\pop.pl line 22.

This is the way i call it:
http://localhost/cgi-bin/jukebox2006...p.pl?name=ID11

Could any one help me fix this error. I am run perl locally and using iis5 .Thanks

Code:

#!/usr/bin/perl

&HTMLGetRequest;
#these are the variable  recived from the edit box.We declare them here
$fname=$rqpairs{"name"}; 


# Set Your Options:
$redirection = 0;       # 1 = Yes; 0 = No

#Note: 
# SONG LOCATIONS


#Defult Subroutines

&HTMLContentType; 


print <<method;

<html>

<head>

<title> Music</title>
</head>

<frameset framespacing="0" border="0" rows="85,70,*" frameborder="0">

I don't think a Perl interpreter parses the raw HTML within it. I think you'd have to use Print to print all the HTML you need. Unlike PHP, I'm not sure if Perl does have a special Perl and HTML formatting tag (IE: <?php ?>).

Perl isn't my thing :|

cN is right... and in addition, I don't believe there are any perl tags. Just complete perl files, so the entire html would need to be in print statements.

No, both the previous posters are wrong. The HEREDOC syntax of your print is fine.

The problem is that you don't import whatever module contains HTMLGetRequest. As a result, Perl emits an error. The web server thus receives no well-formed HTTP headers (these would be written by HTMLContentType) and complains about the violation of the CGI protocol.
The solution is to import whatever module you need.

Code:

use CGI;

Thank u CornedBee for your nice reply. do u mean i need to insall any software to handel the html? could u tell me what module? furthermore do u mean i just put this line in my code : use CGI;

I have no idea what module. Undoubtedly this code comes from some tutorial, right? So there must be the mention of a module somewhere in this tutorial.

Ah... So you learn something new every day. I had assumed Perl would be very similar to PHP.
