I'm trying to get a session variable value set in JS with PHP in back-end (I'm using Symfony).
I set my variable like so:
sessionStorage.setItem('test-name', file);
This works well because I can see in the browser console my session variable and its value. However, on the back-end, I'm unable to get it. I tried the following:
$this->get('session')->get('test-name');
But it doesn't work. What am I doing wrong?
Your JavaScript program and your PHP program are different programs running on (most of the time) different computers.
JavaScript's sessionStorage accesses a store inside the browser.
PHP's sessions access a store on the server.
They are not the same store.
If you want to store the data in a shared location, use the PHP session store. Allow JavaScript access to it by writing a web service and using Ajax to interact with it.
