Read Cookie PHPSESSID in opencart:2.3.0.2

I want to use an opencart database for another website, so users don't need to register their details again.

For example: I sell Clothes (unStitched) on opencart and I also give services for stitching them. Opencart doesn't have a module to do this, so I want to redirect users to another website and there I want to read the user details for further processing.

How can I read PHPSESSID cookie? How does opencart read firstname on edit profile forms?

<?php echo $firstname; ?>

Thanks in advance.

In order to work with the Session data in an Opencart view, you will need to add some code to the controller. First we need to add an item in the $data array that the controller uses to pass variables to the view:

Assuming you want to show this link in a product view, you will need to edit the product controller's index action.

Controller file: public_html\catalog\controller\product\product.php

Find this line:

if ($product_info) {

Add the text inside the brace:

    $data['mysessionvariable'] = $this->session;

You can restrict the available data to the sessionID only using the code below:

    $data['mysessionvariable'] = $this->session->getId();

Now the relevant PHP Session data is available to the view, you can simply reference the session variable in the view wherever your need to. e.g. echo $mysessionvariable['session_id']; or echo $mysessionvariable;

View file: public_html\catalog\view\theme\default\template\product\product.tpl
