Hey guys,

From my tests $SESS->cache doesn’t seem to be persistent between the sessions_start hook and when I try and use it in a plugin on the same page load.

Can one of the EE team or one of the independent developers confirm / explain this?

I thought the $SESS was persistent until the page was finished loading

Cheers

I have successfully used $SESS->cache to pass data between an extension and a plugin. In my case, I used the comment_entries_tagdata hook.

Do you have a simplified use case showing the problem?

After taking a look at the hook (which I should have done before posting my first message), I wonder if you’re forgetting to use a reference. Does your function look something like A or B?

Or referencing the global $SESS object and changing that instead of the passed object would likely be sufficient.

Hey guys,

I have attached a simple example that demonstrates the issue.

Use {exp:lg_pi_test:render} to output the PI $SESS data.

From what I can tell it looks like the plugins create a new $SESS variable???? maybe.

It would be great if one of you guys could take a look at this for me

Ah, that hook is inside the Session class constructor so until it finishes running the constructor, PHP will not have assigned anything to the $SESS global variable yet.  So accepting by reference will be needed (at least for PHP 4 compatibility - 5 will pass objects by reference by default if memory serves):

}

Thanks Derek…

much nicer than my

Work around

eek!  Indeed.  ::holds up garlic and a wooden stake to $_SESSION::

A: function my_session_start_function(&$OBJ)
B: function my_session_start_function($OBJ)

I guess you where right as well…

Thanks for bot of your help…

The documentation for the addon can be found here. The addon should be available soon.

Cheers again. If I was at SXSW I would buy you both a beer

Check for last minute cheap flights across the pond, Leevi!  If you make it, I’ll buy you the beer.
