Cant show old value and edit value in PHP Laravel - php

Question

How to show an old value / query field from database in mysql, and edit value in Laravel. I'm using Laravel 9x and PHP 8x
Controller.php :
public function edit(Business $business)
{
return view('dashboard.bisnis.edit', [
'item' => $business
]);
}
public function update(Request $request, Business $business)
{
$rules = [
'deskripsi' => 'required|max:255',
'pemilik' => 'required|max:255'
];
$validateData = $request->validate($rules);
Business::where('id', $business->id)->update($validateData);
return redirect('/dashboard/bisnis')->with('success', 'Item has been updated !');
}
Blade.php:
#extends('dashboard.index')
#section('container')
<div class="d-flex justify-content-between flex-wrap flex-md-nowrap align-items-center pt-3 pb-2 mb-3 border-bottom">
<h1 class="h2">Edit Data Bisnis</h1>
</div>
<div class="col-lg-8">
<form method="post" action="/dashboard/bisnis/{{ $item->id }}" class="mb-5" enctype="multipart/form-data">
#method('put')
#csrf
<div class="mb-3">
<label for="deskripsi" class="form-label">Deskripsi</label>
<input type="text" class="form-control #error('deskripsi') is-invalid #enderror" id="deskripsi" name="deskripsi" required autofocus
value="{{ old('deskripsi', $item->deskripsi) }}">
#error('deskripsi')
<div class="invalid-feedback">
{{ $message }}
</div>
#enderror
</div>
<div class="mb-3">
<label for="pemilik" class="form-label">Pemilik</label>
<input type="text" class="form-control #error('pemilik') is-invalid #enderror" id="pemilik" name="pemilik" required autofocus
value="{{ old('pemilik', $item->pemilik) }}">
#error('pemilik')
<div class="invalid-feedback">
{{ $message }}
</div>
#enderror
</div>
<button type="submit" class="btn btn-primary">Simpan Perubahan</button>
</form>
</div>
<script>
const deskripsi = document.querySelector('#deskripsi');
const pemilik = document.querySelector('#pemilik');
</script>
#endsection
Also when navigating through my menu such as Business, the sidebar seems cant to be clicked, nor use. Thank you so much

Answer 1

Please try like this:
{{ old('deskripsi') ? old('deskripsi') :$item->deskripsi }}
Please replace this:
return redirect('/dashboard/bisnis')->with('success', 'Item has been updated !');
to
return redirect()->back()->with('success', 'Item has been updated !');

I assume you use Laravel 9
Referring to Repopulating Forms - Validation
Controller.php:
you should use
$deskripsi = $request->old('deskripsi');
$pemilik = $request->old('pemilik');
before
$validateData = $request->validate($rules);
Blade.php:
you should use this on input
value="{{ old('deskripsi') }}"
value="{{ old('pemilik') }}"
By default old will return null if no input exists so we don't need to use nullcheck like
{{old('deskripsi') ?? ''}}

Answer 3

To repopulate value using old() in Laravel you need to return a response withInput(). Not just response.
The return code should
return redirect('/dashboard/bisnis')->with('success', 'Item has been updated !');
change to this
return redirect('/dashboard/bisnis')->with('success', 'Item has been updated !')->withInput();

The solution is i forgot to pass my $id on my controller and route (web.php). Here's my route
Route::controller(GroupServiceController::class)->middleware('auth')->group(function () {
Route::get('/dashboard/gruplayanan', 'index');
Route::get('/dashboard/gruplayanan/create', 'create')->name('gruplayanan.create');
Route::post('/dashboard/gruplayanan', 'store')->name('gruplayanan.store');
Route::get('/dashboard/gruplayanan/edit/{id}', 'edit')->name('gruplayanan.edit');
Route::post('/dashboard/gruplayanan/update/{id}', 'update')->name('gruplayanan.update');
Route::post('/dashboard/gruplayanan/delete/{id}', 'destroy')->name('gruplayanan.delete');
});
and my controller :
public function edit(GroupService $groupService, $id)
{
$groupService = $groupService->findOrFail($id);
return view('dashboard.gruplayanan.edit', [
'item' => $groupService
]);
}
