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 >
    <h1 >Edit Data Bisnis</h1>
</div>

<div >
    <form method="post" action="/dashboard/bisnis/{{ $item->id }}"  enctype="multipart/form-data">
        @method('put')
        @csrf

        <div >
          <label for="deskripsi" >Deskripsi</label>
          <input type="text"  id="deskripsi" name="deskripsi" required autofocus
          value="{{ old('deskripsi', $item->deskripsi) }}">
          @error('deskripsi')
          <div >
            {{ $message }}
          </div>
          @enderror
        </div>

        <div >
          <label for="pemilik" >Pemilik</label>
          <input type="text"  id="pemilik" name="pemilik" required autofocus
          value="{{ old('pemilik', $item->pemilik) }}">
          @error('pemilik')
          <div >
            {{ $message }}
          </div>
          @enderror
        </div>

        <button type="submit" >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

CodePudding user response：

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 !');

CodePudding user response：

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') ?? ''}}

CodePudding user response：

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();
