in reply to string initialization error

the message says the error occured in "line 41". Your code has 8 lines. I assume there are about 37 lines above these 8 lines, and probably some below. The cause of the error lies in the part that you didn't post, or in the way you call your script (e.g. not calling it with the needed parameter(s)) - which you didn't post either.

    Hi guys, First thx for the interest you are been taking, here's a full cgi sample I've rewrite to bbe simple
    #!/usr/bin/perl -w use strict; use warnings; use CGI; my $query = CGI->new ; loadPage (); sub loadPage { my $page = ""; $page = $query->param("page"); if ($page eq 'main') { print "Content-Type: text/html\n\n"; print "main page to load"; }else { print "Content-Type: text/html\n\n"; print "error"; } }
    this code work well now, I'm searching on other modules to see what's wrong thx Alexandre Jaquet
      Almost, you pass arguments to subroutines, not work on globals. see cgi101/Re: Object Identifier? (red flags, more subs)
      #!/usr/bin/perl -- use strict; use warnings; use CGI; Main( @ARGV ); exit( 0 ); sub Main { my $q = CGI->new; my( $headers, $body ) = loadPage( $q ); print $headers, $body; } sub loadPage { my( $query ) = @_; if( authenticate( $q ) ){ my $page = $q->page || 'default'; return ThisPage( $pms, $q ) if $page eq 'thisone'; return ThatPage( $pms, $q ) if $page eq 'thatone'; return DefaultPage( $pms, $q ); } else { return UnauthorizedPage( $pqms, $q ); } }
