我正在用Laravel8和Bootstrap5制作一个博客应用程序。
我在验证我的Add article表单时遇到问题。它无法验证，这意味着即使所需的表单数据未填写，也不会出现错误消息。
在ArticleController控制器中，我有：
namespace AppHttpControllersDashboard;
use IlluminateSupportStr;
use IlluminateSupportFacadesValidator;
use IlluminateSupportFacadesAuth;
use AppHttpControllersController;
use AppModelsArticleCategory;
use AppModelsArticle;
use IlluminateHttpRequest;
class ArticleController extends Controller
{
private $rules = [
'category_id' => 'required|exists:categories,id',
'title' => 'required|string',
'short_description' => 'required|string',
'content' => 'required|longText'
];
private $messages = [
'category_id.required' => 'Please pick a category for the article',
'title.required' => 'Please provide a title for the article',
'short_description.required' => 'The article needs a short description',
'content.required' => 'Please add content'
];
public function categories() {
return ArticleCategory::all();
}
public function add(Request $request) {
// Pass the categories to the articles form
return view('dashboard/add-article',
['categories' => $this->categories()]
);
// Validate form (with custom messages)
$validator = Validator::make($request->all(), $this->rules, $this->messages);
if ($validator->fails()) {
return redirect()->back()->withErrors($validator->errors());
}
$fields = $validator->validated();
// Data to be added
$form_data = [
'user_id' => Auth::user()->id,
'category_id' => $fields['category_id'],
'title' => $fields['title'],
'slug' => Str::slug($fields['title'], '-'),
'short_description' => $fields['short_description'],
'content' => $fields['content'],
'image' => $fields['image'],
'featured' => $fields['featured']
];
// Insert data in the 'articles' table
$query = Article::create($form_data);
if ($query) {
return redirect()->route('dashboard.articles')->with('success', 'Article added');
} else {
return redirect()->route('dashboard.articles')->with('error', 'Adding article failed');
}
}
}
形式：
<form method="POST" action="{{ route('dashboard.articles.add') }}">

路线：
// Article routes
Route::group(['prefix' => 'articles'], function() {
Route::get('/', [ArticleController::class, 'index'])->name('dashboard.articles');
Route::match(['get', 'post'],'/add', [ArticleController::class, 'add'])->name('dashboard.articles.add');
Route::get('/delete/{id}', [ArticleController::class, 'delete'])->name('dashboard.articles.delete');
});
为什么我的表单无法验证
您的public function add()以一个return语句开始。
代码的其余部分是无关的，因为此时您从函数返回。
