@if(Session::has('checkout'))

Hello Guys I've been following this Laravel/livewire E-Commerce series and I encountered this frustrating error. Everything seems to be okay with the code. I just want to show the grand total. But I cannot see it on my page. There is no any error showing. Actually I am kind a newbie. Can I get a solution?

And I don't have proper idea what the meaning of @if(Session::has('checkout')) is

@if(Session::has('checkout'))

Grand Total ${{ Session::get('checkout')['total'] }}

@endif

You are checking if a session variable 'checkout' is set. If it isn't, nothing will run within your condition. So it mustn't be set

When working on web sites you have something that is called a session. This is for instance where we store the data about the user being logged in. This is shared between the backend (php) and the browser.

You can add stuff into this session yourself, to store things between page visits (almost like a tiny database).

session(['checkout' => $data]);

So somewhere on a previous page, I assume you have something like the above code (might not be 100% identical, but has the word session in it). And your code simply checks if that session is set, and assumes its an array with a total key

@if(Session::has('checkout'))

Grand Total ${{ Session::get('checkout')['total'] }}

@endif

in above code,

Grand Total ${{ Session::get('checkout')['total'] }}

this line is ok. I noticed that this line did not run because of @if(Session::has('checkout')) this code.

@Salman98 Yeah if there is no checkout session it should not try to show it.. The code is correct.

@Salman98 I don't see your session store in checkout component. Only see session()->get('checkout'). Where did you store session('checkout'). You need to store it somewhere and check with session::has('checkout') your grand total should appear.

Maybe post a link to this "Laravel/livewire E-Commerce series" ?
