D(ifferent)P(lace) Simple Cache is a WordPress plugin to implement a simple cache of objects at session level.
dpwpsimplecache provides a global variable $dpcache, which is an instantiation of the class DP_Cache already set up to talk to the $_SESSION. Always use the global $dpcache variable (Remember to globalize $dpcache before using it in any custom functions).
If you don’t want to track sessions into db set the $USE_DB_SESSION_MANAGER global variable to 0
<pre><code> global $USE_DB_SESSION_MANAGER;
 $USE_DB_SESSION_MANAGER = 0; // default 1
</code></pre>
Insert object;
<pre><code> $dpcache->set($key,$object);
</code></pre>
Get object:
<pre><code> $object = $dpcache->set($key);
</code></pre>
Count active users:
<pre><code> $count_users = $dpcache->get_sessions_number();
</code></pre>
Count objects in the current user’s $_SESSION:
<pre><code> $dpcache->get_statistics();
</code></pre>
Get all objects in the current user’s $_SESSION:
<pre><code> $dpcache->get_all_values();
</code></pre>
Test if an object exist in the current user’s $_SESSION:
<pre><code> $dpcache->contais($key);
</code></pre>
Delete all objects. If the $all parameter is set to false the method delete only the current user’s $_SESSION, if true truncate the entire table (default false):
<pre><code> $dpcache->flush();
</code></pre>
Prints human-readable information about all objects:
<pre><code> $dpcache->inspect();
</code></pre>
Delete an object in the current user’s $_SESSION:
<pre><code> $dpcache->delete($key);
</code></pre>
Delete single session by ID:
<pre><code> $dpcache->invalidate_single_session($sessid);
</code></pre>
Prints the number of active sessions:
<pre><code> <?php echo dpscache_active_users(); ?>
</code></pre>
At any time, through the administrative page, you can:
<ul>
<li>see all objects in the current user cache</li>
<li>delete all objects in the current user cache</li>
<li>force the deletion of all sessions</li>
<li>force the deletion of a single session</li>
</ul>

User Session Synchronizer

a very clever solution that works flawlessly. great job

perfect work

This plugin works extremely well. 

I am seriously impressed that it does what it says it does. 

The only thing it needs is some better documentation for initial setup. Further, it needs documentation as to what the "User Verify" menu item is for, and the "Email Template".

I thought that was required for users to "verify" themselves to the secondary site.  I think it's just an extra utility to make sure users have valid emails. Seems unnecessary as part of this plugin.

Brilliant! Needs better documetnation
