How to search strings inside Array of arrays using eloquent - arrays

Question

So I have a databse column where the content is an Array like this:
[{"tag_name":"example1"},{"tag_name":"example2"}, {"tag_name":"example3"}]
What I am trying to do is to retrieve videos with a certain tag. All the videopages have specific tags, and when a user clicks one of those tags, it is redirected to a view where similar videos with the same tag will be displayed.
Right now I have the following controller:
public function search($tag){
$tag = urldecode($tag);
$videos = Video::where('tags', 'LIKE', $tag)->paginate(12);
$settings = Detail::find(1);
$ads = Ad::find(1);
return view('search', ['videos' => $videos, 'settings' => $settings, 'ads' => $ads]);
}
And I have the following view (search.blade.php):
#foreach($videos as $video)
<div class="col-lg-4 col-xs-12">
<div class="row justify-content-center">
<img class="articleImg" src="{{$video->imgurl}}">
</div>
<div>
<p class="float-left">{{$title = substr($video->title, 0, 30) . " ..."}}</p>
<small class="duration float-right">{{$video->duration}}</small>
<div class="progress float-right">
<div class="progress-bar bg-success" role="progressbar" style="width: {{$video->rating}}%" aria-valuenow="{{$video->rating}}" aria-valuemin="0" aria-valuemax="100"></div>
</div>
</div>
</div>
#endforeach
The problem is that right now, no videos are shown in my view, even tough i get no errors at all. Is it because the columns has an array of arrays?

Answer 1

I assume it's because your controller is returning 0 videos because tag never match.
You are using LIKE statement without escaping your tag variables with %, so you are looking to match something that is exactly like tag, and because you have an array of tags as a column that will never happen.
One solution you could implement is changing your tag to something like this:
public function search($tag){
$tag = urldecode($tag);
$videos = Video::where('tags', 'LIKE', '%'.$tag.'%')->paginate(12);
$settings = Detail::find(1);
$ads = Ad::find(1);
return view('search', ['videos' => $videos, 'settings' => $settings, 'ads' => $ads]);
}
