Session value access

[mahmudul-elahi7676]

I have set session value like login= true , role = admin
How to access this data in base.html

I already try {{ app.session.get(‘user_id’) }}
But im not getting any value
Can you please help me?

What is in the app variable? This isn't a variable that the framework provides - to access the session you need to pass the session to the template, or use plain PHP inside the template, e.g. $_SESSION

But how to pass session variables in base.html file?

You can set it as a global variable, e.g.

$twig->addGlobal('session', $_SESSION);

@daveh and @mahmudul-elahi7676. I know this is an old post but I came across this a few weeks ago and am struggling with understanding sessions. Added $twig->addGlobal('session', $_SESSION); to View.php. I particularly need to call the id of the blog so I can save it to a database column upon page visit and attempt to create page views from it. If I can just capture the variable (session) so I can use it. I will learn from there.
Still new to php/twig and hope to learn within 12months as much as I can. Any help would be greatly appreciated.

You typically only use the session to save values between pages. If you just want to capture a value when someone visits a page, then you'd usually do this by getting the value from the URL, e.g. example.com/blog/pages/123 - you'd get "123" from the URL and save this to a database table that records number of views for example.
