NAME

AppConfig::CGI - Perl5 module for processing CGI script parameters.

SYNOPSIS

     use AppConfig::CGI;
 
     my $state = AppConfig::State->new(\%cfg);
     my $cgi   = AppConfig::CGI->new($state);
 
     $cgi->parse($cgi_query);
     $cgi->parse();               # looks for CGI query in environment
 
 

OVERVIEW

AppConfig::CGI is a Perl5 module which implements a CGI interface to AppConfig. It examines the QUERY_STRING environment variable, or a string passed explicitly by parameter, which represents the additional parameters passed to a CGI query. This is then used to update variable values in an AppConfig::State object accordingly.

AppConfig::CGI is distributed as part of the AppConfig bundle.

DESCRIPTION

USING THE AppConfig::CGI MODULE

To import and use the AppConfig::CGI module the following line should appear in your Perl script:

     use AppConfig::CGI;
 
 

AppConfig::CGI is used automatically if you use the AppConfig module and create an AppConfig::CGI object through the cgi() method. AppConfig::CGI is implemented using object-oriented methods. A new AppConfig::CGI object is created and initialised using the new() method. This returns a reference to a new AppConfig::CGI object. A reference to an AppConfig::State object should be passed in as the first parameter:

     my $state = AppConfig::State->new(); 
     my $cgi   = AppConfig::CGI->new($state);
 
 

This will create and return a reference to a new AppConfig::CGI object.

PARSING CGI QUERIES

The "parse()" method is used to parse a CGI query which can be specified explicitly, or is automatically extracted from the ``QUERY_STRING'' CGI environment variable. This currently limits the module to only supporting the GET method.

See AppConfig for information about using the AppConfig::CGI module via the cgi() method.
