Hi,
Below I have listet relevant code of two perl files I'm working on.
The problem is that "sub loadFileText" in files.pl, cannot be seen from the
file menus.pl, but "sub load_file" can.
For some reason, which I can't seem to find, the code generates the error
"Undefined subroutine".
Why?
files.pl:
----------
#!perl.exe
use fcntl; # File Control
sub load_file
{
my ($filename) = @_;
my @lines;
sysopen(FH, $filename, O_RDONLY) # Opens the file
or die "Cannot open $filename";
@lines = <FH>; # Reads the entire filecontent into an array of lines
close(FH); # Close the opened file
return @lines;
}
sub loadFileText
{
my $filename = $_[0];
my $text = "";
my @lines = load_file($filename);
for(my $i=0; $i<scalar(@lines); $i++)
{
$text .= $lines[$i];
}
return $text;
}
1;
menus.pl:
--------------
#!perl.exe
use XML::Parser::Lite; # XML Support
require "../../cgi-bin/soren/files.pl";
sub showMenu
{
# Parameters:
my $sSource = $_[0];
my $sID = $_[1];
$sLanguageID = $_[2];
my $xmlDoc = loadFileText($sSource); # <=== loadFileText is
undefined ??????
my $sMenu .= createMenu($xmlDoc, $sID);
print $sMenu;
}
1;
