Old data not displayed in edit.blade.php - php

Question

This is my edit method:
public function edit(User $user)
{
// ...
return view('admin.biodata.edit',
[
'title' => 'Edit Biodata',
'active' => 'biodata',
'majors' => Major::all(),
'biodata' => $user
]
);
}
edit.blade.php
#extends('admin.adminDashboard.layouts.main')
#section('container')
<div class="d-flex justify-content-between flex-wrap flex-md-nowrap align-items-center pt-3 pb-2"></div>
<h1>Edit Student</h1>
<div class="container">
<form action="{{url('admin/biodata')}}" method="POST">
#csrf
<input type="hidden" name="id" value="{{ $biodata->id }}">
<div class="form-group">
<label for="name">Name</label>
<input type="text" class="form-control" id="name" name="name" placeholder="Enter name" value="{{$biodata->name}}">
</div>
<div class="form-group">
<label for="nrp">NRP</label>
<input type="text" class="form-control" id="nrp" name="nrp" placeholder="Enter NRP" value="{{$biodata->nrp}}">
</div>
<div class="form-group">
<label for="email">Email</label>
<input type="email" class="form-control" id="email" name="email" placeholder="Enter email" value="{{$biodata->email}}">
</div>
<div class="form-group">
<label for="address">Address</label>
<input type="text" class="form-control" id="address" name="address" placeholder="Enter address" value="{{$biodata->address}}">
</div>
<div class="form-group">
<label for="generation">Generation</label>
<input type="text" class="form-control" id="generation" name="generation" placeholder="Enter generation" value="{{$biodata->generation}}">
</div>
<div class="form-group">
<label for="major">Major</label>
<select class="form-control" id="major" name="major_id">
#foreach ($majors as $major)
<option value="{{$major->id}}">{{$major->nama_jurusan}}</option>
#endforeach
</select>
</div>
<button type="submit" class="btn btn-primary">Submit</button>
</form>
#endsection
When I press the edit button from the index view, the old data is not displayed in the view admin.biodata.edit. I thought I have already passed the user data through the biodata variable.

Answer 1

Replace the value in the template with
value="{{old('name',$biodata->name)}}"
