Passing multiple variable using compact in Laravel-CodePudding

I have a function which return the view with multiple variable. The code is

HomeController.php

public function profilePage(){
        $data = User::all();
        $book = Library::all();
        return view('page.profile' , compact(array('data', 'book')));
}

profile.blade.php

@include('layouts.sidebar')
.
.
.
 @foreach($book as $Library)
     <tr>
        <td>{{$Library->book}}</td>
        <td>{{$Library->name}}</td>
        <td>{{$Library->author}}</td>
        <td>{{$Library->price}}</td>
    </tr>
 @endforeach

sidebar.blade.php

<div >
  <a href="{{ url ('profile' , $data -> first())}}" >{{Auth::user() -> name }}</a>
</div>

When i try to refresh the browser to see the changes. It'll show error "undefined variable $book"

Illuminate\ Foundation\ Bootstrap \ HandleExceptions: 176 handleError

on line

addLoop($currentLoopData); foreach($currentLoopData as $Library): $env->incrementLoopIndices(); $loop = $env->getLastLoop(); ?>

Before i added the module to retrieve the data from Library, the code just work fine. So is this the correct approach to pass multiple variable into view?

Try to use this instead, and make sure you are loading the correct blade file, in your case, it's profile.blade.php inside the page folder.

public function profilePage(){
    $data = User::all();
    $book = Library::all();

    return view('page.profile', [
        'data' => $data,
        'book' => $book,
    ]);

}

CodePudding user response：

There are 4 ways for passing data to view:

1 -

 return view('page.profile' , ['book' => $book, 'data' => $data]);

2 -

return view('page.profile' , compact('book', 'data'));

3 -

return view('page.profile')
    ->with('data' => $data)
    ->with('book' => $book);

4 - Not recommended

return view('page.profile' , get_defined_vars());
