Laravel 5 search in a JSON file and show data - php

Question

I have a search engine with typeahead. What I want is that after doing a search and giving the submit, show the results. This gives two problems: first it returns an empty array and second, it does not allow me to access the properties telling me it is not an object.
In controller, I used collect() to allow me to access the properties, but it does not work and WHERE either.
public function store(Request $request)
{
$url = 'storage/json/es/noticia.json';
$datos = file_get_contents($url);
$data = json_decode($datos, true);
$data = collect($data)->where("title","LIKE","%{$request->texto}%")->all();
return view('web.buscar.index', compact('data'));
}
If I use $data = collect($data)->all(); I can see the collection:
array:8 [▼
0 => []
1 => array:4 [▼
"id" => 2
"title" => "There is a title"
"lead" => "There is a lead"
"slug" => "there-is-a-title"
]
2 => array:4 [▶]
3 => array:4 [▶]
4 => array:4 [▶]
5 => array:4 [▶]
6 => array:4 [▶]
7 => array:4 [▶]
]
Then If I try: $value->title in the view I have the error: Trying to get property 'title' of non-object. In the view I have:
{!! Form::open([
'route' => 'buscar',
'id' => 'buscar',
'name' => 'buscar',
'class' => 'buscador col-xs-12',
'method' => 'POST',
'accept-charset' => 'utf-8'
]) !!}
<input id="texto" name="texto" class="input_buscador typetitulo" autocomplete="off" type="text"/>
{!! HTML::image('images/web/icons/lupa.svg', '', array('height' => '30', 'class' => 'boton_buscador', 'onclick' => 'document.buscar.submit()') ) !!}
{!! Form::close() !!}
#if(isset($data))
#foreach($data as $value)
<span>{{$value->title}}</span><br>
#endforeach
#endif
If I use $data = collect($data)->pluck('title'); in the controller and in the view I don't call the property 'title', this works, but it's not what I want because I need to access other properties too.
Any idea? Thanks in advance!

This is failing because the first array in your array does not have any values, so you will get undefined index, remove any empty arrays by doing
public function store(Request $request)
{
$url = 'storage/json/es/noticia.json';
$datos = file_get_contents($url);
$data = json_decode($datos, true);
$data = array_filter($data);
$data = collect($data)->where("title","LIKE","%{$request->texto}%")->all();
return view('web.buscar.index', compact('data'));
}
Or you can test to see if it is there in your foreach
#foreach($data as $value)
<span>{{$value->title ?? ''}}</span><br>
#endforeach
You can then search the collection using a filter
collect($data)->filter(function ($item) use ($request) {
return $item->title == $request->texto;
)
You can edit the return to be more granular using stristr etc
