我只是在嘗試更新資料時遇到錯誤。我使用的是post方法而不是push。我嘗試添加 @method('PUT') 但這也不起作用。
創建新類別可以正常作業，但是當我嘗試編輯某些內容時，它只會引發錯誤。我也嘗試使用 route::put 但這沒有用。
我的 CategoryController.php
<?php
namespace App\Http\Controllers\Admin;
use App\Http\Controllers\Controller;
use App\Models\Category;
use Illuminate\Http\Request;
class CategoryController extends Controller
{
/**
* Display a listing of the resource.
*
* @return \Illuminate\Http\Response
*/
public function index()
{
//
$data = Category::all();
return view('admin.category.index', [
'data' => $data
]);
}
/**
* Show the form for creating a new resource.
*
* @return \Illuminate\Http\Response
*/
public function create()
{
return view('admin.category.create');
}
/**
* Store a newly created resource in storage.
*
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
*/
public function store(Request $request)
{
$data = new Category;
$data->parent_id = 1;
$data->title = $request->title;
$data->keywords = $request->keywords;
$data->description = $request->description;
$data->status = $request->status;
$data->save();
return redirect('admin/category');
}
/**

public function show(Category $category)
{

/**

public function edit(Category $category, $id)

我的路線
// Admin category routes
Route::get('/admin/category', [AdminCategoryController::class,'index'] )->name('admin_category');
Route::get('/admin/category/create', [AdminCategoryController::class,'create'] )->name('admin_category_create');
Route::post('/admin/category/store', [AdminCategoryController::class,'store'] )->name('admin_category_store');
Route::get('/admin/category/edit/{id}', [AdminCategoryController::class,'edit'] )->name('admin_category_edit');
Route::post('/admin/category/update/{id}', [AdminCategoryController::class,'edit'] )->name('admin_category_update');
uj5u.com熱心網友回復：
我會對您的代碼進行這些修改：edit.blade：
<form action="/admin/category/update/{{$data->id}}" method="POST">
@csrf
@method('PUT')
.........
路線：
Route::put('/admin/category/update/{id}', [AdminCategoryController::class,'update'] )->name('admin_category_update');
檢查它是否有效。
還有一件事：如果您正確創建了模型系結，您的更新函式可能如下所示：
public function update(Request $request, Category $category, $id)
{
//
$category->parent_id = 1;
$category->title = $request->title;
$category->keywords = $request->keywords;
$category->description = $request->description;
$category->status = $request->status;
$category->save();
return redirect('admin/category');
}
那是因為你已經有了模型：public function update(Request $request, **Category $category**, $id)
