How to compare a value from the search bar to the one from the database in laravel - laravel

Question

I am trying to use the search box in my Laravel project but I keep getting the same error since morning
Here is my Search controller
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class SearchController extends Controller
{
public function index()
{
return view('search.index');
}
public function Search(Request $request)
{
$serial_number= $request->input('search');
$results =DB::table('animals')->where(function ($query) use ($serial_number) {
$query->where('serial_number','LIKE',"%$serial_number%");
})->latest()->get();
return view('search',compact('results'));
}
}
My routes
Route::get('/search','SearchController#index')->name('search');
Route::post('/search','SearchController#search')->name('search');
and finally my view
#extends('layouts.app')
#section('content')
<form action="{{ route('search') }}" method="POST">
<div class="p-1 bg-light rounded rounded-pill shadow-sm mb-4">
<div class="input-group">
<input type="search" name="search" placeholder="Here the animal serial number..." aria-describedby="button-addon1" class="form-control border-0 bg-light">
<div class="input-group-append">
<button id="button-addon1" type="submit" class="btn btn-link text-primary"><i class="fa fa-search"></i></button>
</div>
</div>
</div>
</form>
#if($results)
<div class="container">
<div class="row justify-content-center">
<div class="col-md-8">
<div class="card">
<div class="card-header">
<h3>Details for the animal</h3>
</div>
<div class="card-body">
<div class="col-12">
<p><strong>Id: </strong>{{ $results->id }}</p>
<p><strong>Animal: </strong>{{ $results->type->category }}</p>
<p><strong>Gender: </strong>{{ $results->gender }}</p>
<p><strong>Place Of Birth: </strong>{{ $results->user->address->city }}</p>
<p><strong>Farm: </strong>{{ $results->user->name }}</p>
<p><strong>Date: </strong>{{ $results->created_at }}</p>
</div>
</div>
</div>
</div>
</div>
</div>
#endif
#endsection
For me, I think that the problem is in the controller on that line $result which makes the view give the error
419|Page Expired or "Facade\Ignition\Exceptions\ViewException
Undefined variable: results (View:
/Users/macair13/MeatracProject/resources/views/search/index.blade.php)"

Answer 1

You need to include the CSRF token or exclude that URL from the CSRF token check.
<form ...>
#csrf
...
</form>

Also you are not passing a results variable to your 'search' view from the Controller's index method. You will need to check if $results isset in your view or pass it to your view.

Answer 2

public function view (Request $request)
{
$search=$request['search'] ?? "";
if($search !=""){
//where
$data=File::where('id','like','%'.$request->search.'%')
->orwhere('name','like','%'.$request->search.'%')
->orwhere('file','like','%'.$request->search.'%')->get();
}
else{
$data = File::all();
}
$p = compact('data','search');
return view('upload_data')->with($p);
// $data = File::all();
// return view('upload_data',compact('data'));
}
