缺少ArticleController :: update（）的参数1

Question

我想编辑并保存网站中的某些字段，但这会将我重定向到错误。您能告诉我我的视图出了什么问题吗？ 这是我的视图，路线和控制器，也许您可​​以看一下。这不是我的代码，但是我试图弄清楚如何使其工作。 Missing argument 1 for App\\Http\\Controllers\\ArticleController::update()

我的观点：

{!! Form::open(['class' => '','url' => 'admin/article/update','id' => 'sky-form3']) !!}

我的路线：

Route::post('admin/article/update/{type?}/{id?}', 'ArticleController@update');

更新功能：

public function update($type, $id)
    {
        if($type == "News")
        {
            $article = \App\News::find($id);
            $article->subject = Request::input('subject');
            $article->public = Request::input('public');
            $article->category_id = Request::input('category_id');
            $article->information = Request::input('information');
            $article->save();
        }

        if($type == "Opinion")
        {
            $article = \App\Opinion::find($id);
            $article->subject = Request::input('subject');
            $article->public = Request::input('public');
            $article->category_id = Request::input('category_id');
            $article->opinion = Request::input('opinion');
            $article->save();
        }

        if($type == "Event")
        {

            $article = \App\Event::find($id);
            $article->subject = Request::input('subject');
            $article->public = Request::input('public');
            $article->category_id = Request::input('category_id');
            $article->event_type_id = Request::input('event_type_id');
            $article->country = Request::input('country');
            $article->save();


        }

        if($type == "CareerSolution")
        {
            $article = \App\CareerSolution::find($id);
            $article->subject = Request::input('subject');
            $article->public = Request::input('public');
            $article->topic_category_id = Request::input('topic_category_id');
            $article->topic_subcategory_id = Request::input('topic_subcategory_id');
            $article->location = Request::input('location');
            $article->on_offer = Request::input('on_offer');
            $article->city = Request::input('city');
            $article->employment_type = Request::input('employment_type');
            $article->estimated_salary = Request::input('estimated_salary');
            $article->quantity = Request::input('quantity');
            $article->expires_at = Request::input('expires_at');
            $article->optional = Request::input('optional');
            $article->save();
        }

        if($article != ""){
            flash(trans($type.' has been Updated'), 'success');
        }else{
            flash(trans($type.' has not been updated'), 'warning');
        }

        return redirect(URL::previous());
    }
}

Answer 1

我认为问题出在您的路线上。 {type?}未定义，请尝试将其从路由中删除，这应该没问题。

Route::post('admin/article/update/{id?}', 'ArticleController@update');

Answer 2

您在路由上定义了两个可选参数，因此需要在update方法中将它们定义为可选参数。

public function update($type = false, $id = false)

另外，您还需要确保以打开的形式传递它们，最好将路由名称与

Form::open(array('route' => array('route.name', ['id' => $id, 'type' => $type])))

---

但是，恕我直言，最好避免在定义路由时使用多个可选参数。

Answer 3

尝试像这样更改路线

Route::post('admin/article/update/{type?}/id/{id?}', 'ArticleController@update')->name('update.article');

您可以简单地将其用作

{{ route('update.article', ['type' => 'some_type', 'id' => 'some_id'] }}

接着

    Form::open(array('route' => array('update.article', ['type' => 'some_type', 'id' => 'some_id']), 'method' => 'POST'))
    @csrf

Answer 4

根据您的路线，函数标头应为：public function update（$ type = null，$ id = null）

一点改进（不会直接解决您的问题，但可能会有所帮助）。 使用模型绑定！ 参见https://laravel.com/docs/5.8/routing#route-model-binding
