Request contains null although the input has been entered

I'm trying to update my data with Laravel. I'm able to create, read, delete the data but somehow i cannot update my data. I already checked my controller,model,route and view but i don't think there's any typo or anything. It only redirects to it's index page without being updated although i have entered new input. There's no error message at all so i checked where is the problem. So i checked my update function in my controller and tried to show the request by echo "$request->kode_kontak"; and echo $request->kode_kontak; but it shows nothing which i assume that it's null/empty but when i echo "yes" it showed on the screen "yes" i tested this because i want to know if the function itself is working so the problem here is that the request contains null, no wonder i cannot update it. Why is the request isn't passed? why is it like this? and how to fix it?

Route for edit and update

Route::get('contact/{contact}/edit', 'ContactController@edit')->name('contact.edit');
Route::patch('contact/{contact}','ContactController@update')->name('contact.update');

Controller with edit and update function

use Illuminate\Http\Request;
use App\Contact;
use DB;

public function edit($kode_kontak){
        $contact = DB::table('contact')->where('kode_kontak',$kode_kontak)->get();
        return view('contact.edit',['contact' => $contact]);
    }

public function update(Request $request){
        DB::table('contact')->where('kode_kontak',$request->kode_kontak)->update([
            'email' => $request->email,
            'telepon' => $request->telepon,
        ]);
        return redirect('contact');
    }

Model

class Contact extends Model
{
    public $timestamps = false;
    
    protected $table = 'contact';

    protected $fillable = [
        'kode_kontak',
        'kode_pegawai',
        'email',
        'telepon'
        
    ];

    protected $primaryKey = 'kode_kontak';
}

View of edit.blade.php

<div id="contact">
    <h2>Edit Contact</h2>
    @foreach($contact as $p)
        <form action="{{ route('contact.update', ['kode_pegawai' => $p->kode_pegawai]) }}" method="POST">
    @csrf
    @method('patch')
        <div class="form-group">
            <label for="kode_contact" class="control-label">Kode Kontak</label>
            <input type="text" name="kode_kontak" id="kode_kontak" class="form-control" value="{{ $p->kode_kontak}}" disabled>
        </div>
        <div class="form-group">
            <label for="kode_pegawai" class="control-label">Kode Pegawai</label>
            <input type="text" name="kode_pegawai" id="kode_pegawai" class="form-control" value="{{ $p->kode_pegawai}}" disabled>
        </div>
        <div class="form-group">
            <label for="email" class="control-label">Email</label>
            <input type="text" name="email" id="email" class="form-control" value="{{ $p->email}}">
        </div>
        <div class="form-group">
            <label for="telepon" class="control-label">Telepon</label>
            <input type="text" name="telepon" id="telepon" class="form-control" value="{{ $p->telepon}}">
        </div>
        <div class="form-group">
            <input class="btn btn-primary form-control" type="submit" value="Simpan">
        </div>
    </form>
    @endforeach
</div>

$request->kode_kontak is $contact here, $request->kode_kontak is not available in $request, change $contact instead :

public function update(Request $request, $contact){
   DB::table('contact')->where('kode_kontak',$contact)->update([
      'email' => $request->email,
      'telepon' => $request->telepon,
   ]);
  return redirect('contact');
}

Your issue is that you have disabled those inputs. Disabled inputs will not be submitted.

If you want to display the disabled inputs, but still PATCH the values, you will need to add hidden inputs with those values like:

        <div class="form-group">
            <label for="kode_contact" class="control-label">Kode Kontak</label>
            <input type="text" id="kode_kontak" class="form-control" value="{{ $p->kode_kontak}}" disabled>
            <input type="hidden" name="kode_kontak" value="{{ $p->kode_kontak}}">
        </div>
        <div class="form-group">
            <label for="kode_pegawai" class="control-label">Kode Pegawai</label>
            <input type="text" id="kode_pegawai" class="form-control" value="{{ $p->kode_pegawai}}" disabled>
            <input type="hidden" name="kode_pegawai" value="{{ $p->kode_pegawai}}">
        </div>

Hope that helps!
