Re: Config::Tiny Module

Maybe you (=the webserver user who runs the CGI script) don't have permission to write to the file?

$Config->{section}->{ipaddress} = $newvalue;
$Config->write( 'file.conf' );
[download]

works fine for me, as long as the file is writable.

Really!? It writes just not what it should. `$Config->{section}->{ipaddress} = $newvalue; $Config->write( 'file.conf' );` [download] The above just doesn't write. Put the $newvalue is single quotes and it write "$newvalue" !	[reply] [d/l]

Really!? Yes. I tried with `my $newvalue = '127.0.0.1'; ...` [download] and `127.0.0.1` is exactly what ended up in the file. As for single quotes: they don't interpolate, that's why you get `"$newvalue"` literally.	[reply] [d/l] [select]

There are 2 pages involved. The first is a form that passes the value $newvalue to the CGI script. The CGI script receives that value fine and I can dump it to screen fine. If I try and write that value to the config file one of two things happens. Firstly, if I single quote the value '$newvalue' it will write the literal string $newvalue to the config file. So this rules out any permissions issues with writing to the file. Any other format ("$newvalue" or \$newvalue) will not write to the file at all. It simply ignores it. If I set the variable value myself in the CGI script (that is, not pass it from a form) and then try and write that value to the file it works.	[reply]

Sorry - I should have been much clearer. Setting the variable in the same file works fine. Posting it from another form doesn't.	[reply]
