laravel request not redirect right page

Question

I want to make a filter based on request kelas on database table. It gives me no error just when I click one of the filter, it don't show jadwal page with my filter. It show the main page but the url is right like lps.com/?jadwal-2

I have done make a middleware called SanitizeMiddleware from stackoverflow but still not worked.

This is my route web.php

Route::get('/', 'HomepageController@index');

Route::resource('pengumuman', 'PengumumanController');
Route::resource('jadwal', 'JadwalController');
Route::resource('rapot', 'RapotController');

This is my index() from my JadwalController

public function index()
{
    if (request()->has('kelas')) {
        $jadwal = jadwal::where('kelas', request('kelas')); 
    } else {
        $jadwal = jadwal::all();
    }

    return view('jadwal.index')->with('jadwal',$jadwal);

    //$jadwal = jadwal::all();
    //return view('jadwal.index')->with('jadwal',$jadwal);
}

This is my index.blade.php

<div class="container">
    <br>
    <h1>
        <strong>Jadwal Pelajaran</strong>
    </h1>
    <a href="/?kelas=1">jadwwal kelas 1</a>
    <a href="/?kelas-2">jadwal kelas 2</a>
    <a href="/?kelas-3">jadwal kelas 3</a>
    </form>
    <table class="table table-bordered">
        <thead>
            <tr>
                <th scope="col"></th>
                <th scope="col">07.00-08.00</th>
                <th scope="col">08.00-09.00</th>
                <th scope="col">09.00-10.00</th>
                <th scope="col">10.00-11.00</th>
                <th scope="col">10.00-12.00</th>
                <th scope="col">action</th>
            </tr>
        </thead>
        <tbody>
            @if(count($jadwal)>0)
                @foreach($jadwal as $jadwals)
                    <tr>
                        <th scope="row">{{$jadwals->hari}}</th>
                        <td>{{$jadwals->jamke1}}</td>
                        <td>{{$jadwals->jamke2}}</td>
                        <td>{{$jadwals->jamke3}}</td>
                        <td>{{$jadwals->jamke4}}</td>
                        <td>{{$jadwals->jamke4}}</td>
                        <td>
                            <a href="/jadwal/{{$jadwals->id}}/edit" class="btn btn-info">Edit</a>
                        </td>
                    </tr>
                @endforeach
            @else
                <p>tidak ada jadwal</p>
            @endif
        </tbody>
    </table>
</div>

And this is the picture of problem:-

this is my jadwal page before filter

this my page after i click the filter using request()

Answer 1

HTML URL talking, lps.com/?jadwal-2 is just calling the home page with a GET parameter called jadwal-2 with no value at all. lps.com/jadwal is good, lps.com/jadwal?kelas=2 is good. forget the dash

Using / in href attribute tell the system to start from the the top level path. Change to relative like :

<a href="?kelas=1">jadwwal kelas 1</a>
<a href="?kelas-2">jadwal kelas 2</a>
<a href="?kelas-3">jadwal kelas 3</a>

So being on page lps.com/jadwal will result in url lps.com/jadwal?kelas=1 which is the correct syntax and pattern.

Answer 2

its just a simple url issue

as you see the list of jadwal is displayed in the route

lps.com/jadwal

What is the issue as you see

<a href="/?kelas=1">jadwwal kelas 1</a>
<a href="/?kelas=2">jadwal kelas 2</a>
<a href="/?kelas=3">jadwal kelas 3</a>

While Clicking this any of the link its redirecting to

For Example If i Clicked jadwwal kelas 1

lps.com/?kelas=1

So Its not redireting to lps.com/jadwal?kelas=1

So Try to change

<a href="jadwal/?kelas=1">jadwwal kelas 1</a>
<a href="jadwal/?kelas=2">jadwal kelas 2</a>
<a href="jadwal/?kelas=3">jadwal kelas 3</a>

And the final thing if you are using the pagination

{{$jadwal->links()}}

This Will only add the ?page=yourCurrentPageNumber

But in Some situation You need both the filters and pagination

So Try below Method

{{$jadwal->appends(request()->input())->links()}} 

It will appends all the GET Request Parameter

So If You need to vist the nth page of kelas=1 its will work

Hope its helps
