imarc/craft-dbsessions

A database session handler specifically for Craft CMS

Craft DB Sessions Handler

For Craft 2.x. Sets up a database sesssion handler using Craft's existing DB and Caching libraries to ensure that only a single database connection is ever created., _(*1)

This is not a true Craft plugin, but is best distributed as one., _(*2)

Installation

Install through composer (recommended):, _(*3)

composer require imarc/craft-dbsessions

Alternatively place all files into a craft/plugins/dbsessions directory., _(*4)

Usage

Add the following at the very top of your public/index.php file:, _(*5)

require __DIR__ . '/../craft/plugins/dbsessions/SessionHandler.php';
\Imarc\CraftDatabaseSessions\SessionHandler::register();

Your sessions will now be stored in craft's database instead of on the filesystem., _(*6)

The dbsessions_sessions database table used by this library should be created automatically. If there are restrictive database permissions, you can use the following migration to create the table manually:, _(*7)

(sql) CREATE TABLE dbsessions_sessions ( id char(128) NOT NULL PRIMARY KEY, expire int(11) NULL, value longblob NULL );, _(*8)

Why?

Sometimes, in an high-availability environment with multiple application servers, storing the sessions directly on the filesystem is not ideal as there is no consistency to which application server an end-user is hitting. Redis or Memcached is recommended over using the DB for sessions as Craft can work with those out of the box, but DB is fine if those services aren't available for whatever reason., _(*9)
