[EDIT - I have posted the answer to my question below]

EE 5.2.4

I'm having issues trying to use $_SESSION in EE.

What I would like to do is save an Amazon cart ID in the $_SESSION. Working in regular PHP I'm familiar with this: $_SESSION['cart_id'] = 1234. However when I try to do this in EE I get errors and/or nothing happens.

I thought that maybe what I'm looking for is the cache-access functionality:

So in my class I have this ee()->session->set_cache('amz_cart', 'id', $value);, and in my view I'm trying to see what returns from this ee()->session->cache('amz_cart', 'id');.

Nothing returns with this. Can anyone point me in the right direction?

Thanks!

  • btw for v 5 you need to use differently - ee()->session->cache['amz_cart']['id'] = $value & ee()->session->cache['amz_cart']['id'] for return data.

  • Can I get more information about this? None of the options I'm seeing are working the same way that $_SESSION does. I would simply use $_SESSION but when I do var_dump($_SESSION) I get Undefined variable: _SESSION. I need this variable to be global. It seems like it should be a simple answer and I'm not sure why $_SESSION isn't permitted.

Well, you can use flashdata to achieve your requirement. For this please follow below syntax.

To set the Flashdata:-

ee()->session->set_flashdata('your_key', 'your_value');

To get the Flashdata:-

echo ee()->session->flashdata('your_key');

  • Thanks for the response Barach! I've been trying to work with this and have run into a few problems. The docs say flashdata only works when followed by a redirect. I'm using $.ajax to run a class method and in that method I have ee()->session->set_flashdata('amz_cart', 'test'); followed by ee()->functions->redirect(ee()->functions->fetch_current_uri());. This does not appear to persist, however, and I need it to be checkable across the site (if this session variable exists, show a cart in the header, for ex).

  • I should add that if I echo the flashdata after running the redirect in the class method echo ee()->session->flashdata('amz_cart'); I get {"amz_cart":"test"}, but if I refresh the page I can't seem to retrieve the flashdata.

  • session->cache it is also "flash" content. It is not like $_SESSION

It appears as though I've answered my own question by trial and error.

In my class method I can set the value like this: 

$_SESSION['amz_cart']['id'] = $value;

and in the template when I want to access that value I have to do this:

<?php
    session_start();
    echo $_SESSION['amz_cart']['id'];
    session_write_close();
?>

I'm not sure why it works this way but it appears to be working for my needs for the time being.

I'm still interested in a more elegant or EE-based solution that will work the same way.

Thanks everybody!

    it works exactly because you need to start sessions first. Two moments - better to use if ( session_id() == "" ) { session_start(); } And be careful if you do code which should work with load balancer and the user could be switch between servers because $_SESSION is not cross servers data
