Laravel - Selecting data from two different tables to show on blade.html - php

Question

On my index.blade i like to show two different sets of data, one is a list of computers the other one list of categories. two different type of data. in my controller I have
public function index()
{
// Select data from table assets
$assets = DB::table('assets')->where('status', '1')->orderBy('type', 'asc')->paginate(10); //pass all the employees to a Var and send it to our page using "with" also puts page # at the bottom
//select data from table assetrefs
$categories = DB::table('assetrefs')->get();
//bind data and send using 'with'
return view('assets.index')->with('assets', $assets)->with('categories', $categories);
}
on my view side I have these two loops
#if(count($categories) > 1)
#foreach($categories as $row)
{!!Form::open(['action' => ['AssetsController#showType', $row->title], 'method'=> 'POST', 'class'=> 'pull-left'])!!}
{{Form::submit('Show '. $row->title, ['class' => 'btn btn-danger'])}}
{!!Form::close()!!}
#endforeach
#else
<p> no content </p>
#endif
This shows a bunch of button with categories
<div class="well"></div>
<!-- lists all the available assets in a div all types are mixed but sorted -->
#if(count($assets) > 1)
#foreach($assets as $asset)
<div class="well">
<h3>{{$asset->type}}, {{$asset->make}} - {{$asset->model}} </h3>
<small> {{$asset->sn}}</small>
<small> View this account</small>
</div>
#endforeach
{{$assets->links()}}
#else
<p> no content </p>
#endif
this shows a list of all computers
When I load the page I get
2/2 ErrorException
Undefined variable: categories (View: resources\views\assets\index.blade.php)

Answer 1

Can you please pass data to view by making use of array instead of with like below:
public function index()
{
// passing data without with
$data['assets'] = DB::table('assets')->where('status', '1')->orderBy('type', 'asc')->paginate(10);
$data['categories'] = DB::table('assetrefs')->get();
return view('assets.index',$data);
// in case if you want to use with then
// return view('assets.index')->with($data);
}
Or even if you don't want to use $data variable want to keep $asset and $categories variable as it is then
public function index()
{
// passing data without with
$assets = DB::table('assets')->where('status', '1')->orderBy('type', 'asc')->paginate(10);
$categories = DB::table('assetrefs')->get();
return view('assets.index',compact('assets','categories'));
}
You can check how compact function is working in php by url -> http://php.net/manual/en/function.compact.php

Answer 2

Try this in your Controller in place of your view() call:
return view('assets.index', compact('assets', 'categories'));
Have a look at Passing Data To Views and you'll see view()->with() is suited for passing individual pieces of data whereas passing an array as a second argument is required for multiple variables. Here we're passing an array of your already defined assets and categories via PHP's compact function.
