Is there a way to update controller variable value from view

MainController.php

$pageData['count'] = 0;
$data = array('data' => $pageData);
return view('home', $data);

In my home view i included another view

<!-- Block 1-->
@include('home.prodbox', $prodData = $data['data'])

<!-- Block 2-->
@include('home.prodbox', $prodData = $data['data'])

In the first block foreach loop count starts with 0. Depends of data, loop runs multiple times and count will increase. So i want to pass the count of first block to second block Like if first block loop count is 4 then i want second block count to start from 5. So in prodbox i did it like this:

prodbox.blade.php

$tabcount = $data['count'];

And at the end of prodbox.blade.php file, I did this

$data['count'] = $tabcount;

But when second block runs it starts with 0 again. I set the data variable to latest count but why it always zero. Is there a way i update data from view to controller.

May be because you/your code initialize variable again. You should try reference &$data['count'] – daremachine Dec 05 '18 at 06:47
Like this ? &$data['count'] = $tabcount; – DIGITAL JEDI Dec 05 '18 at 06:56
yes and in second block get data again from reference. http://php.net/manual/en/language.references.pass.php – daremachine Dec 05 '18 at 07:23

&$data gives syntax error in laravel view – DIGITAL JEDI Dec 05 '18 at 07:31
and @include('home.prodbox', $prodData = &$data['data']) – daremachine Dec 05 '18 at 07:32
So i have to pass throw include statement. Currently its in file – DIGITAL JEDI Dec 05 '18 at 07:34
