NAME

WWW::Session::Storage::MySQL - MySQL storage for WWW::Session

DESCRIPTION

MySQL backend for WWW:Session

VERSION

Version 0.12

SYNOPSIS

This module is used for storring serialized WWW::Session objects in MySQL

Usage :

use WWW::Session::Storage::MySQL;

my $storage = WWW::Session::Storage::MySQL->new({ 
                            dbh => $dbh,
                            table => 'sessions',
                            fields => {
                                sid => 'session_id',
                                expires => 'expires',
                                data => 'data'
                            }
            });
...

$storage->save($session_id,$expires,$serialized_data);

my $serialized_data = $storage->retrive($session_id);

The "fields" hasref contains the mapping of session internal data to the column names from MySQL. The keys are the session fields ("sid","expires" and "data") and must all be present.

The MySQL types of the columns should be :

  • sid => varchar(32)

  • expires => DATETIME or TIMESTAMP

  • data => text

This method accepts only one argument, a hashref that must contain the fallowing data:

  • table The name of the table where the sessions will be stored

  • fields A hash ref containing the falowing keys

    • sid The same of the database field which will store the session id

    • expires The same of the database field which will store the expiration time

    • data The name of the field where the session data will be stored

save
