in reply to Calling a sub-routine in CGI

Hi Anonymous Monk,

Hmmm... Yes, it easy, depending on what you want to do. Are you

a) Trying to execute what ever is in &toggle_on and put the output of that text in your A HREF command, or are you

b) Trying to get &toggle_on to execute when you click the ON hyperlink? It almost looks like this is what you're trying to do. If so, you're going the wrong way.

Solution A 

print "<a href=" . &toggle_on . ">ON</a>";

Solution B 

  #get the UNWEB procedure in here
  $FORM=&unweb;

if($FORM{action} eq "toggleon")
{
   &toggle_on;
}
else
{
   print "<a href=\"?action=toggleon\">ON</a>\n";
}

This is a very simplified way of going.

      Here's what you need... 
      sub unweb
{

    if($ENV{QUERY_STRING} eq "")
    {
        read(STDIN, $buffer, $ENV{'CONTENT_LENGTH'});
    }
    else
    {
        $buffer = $ENV{QUERY_STRING};
    }
    @pairs = split(/&/,  $buffer);
    foreach $pair (@pairs)
    {
        ($name, $value) = split(/=/, $pair);
        $value =~ tr/+/ /;
        $value =~ s/%([a-fA-F0-9][a-fA-F0-9])/pack("C", hex($1))/eg;
        $value =~ s/~!/ ~!/g;
        $FORM{$name} = $value;
    }

    return %FORM;
}

      Have a look at cgi101. That's where I started with CGIs.
