Question

我制作了Post A Ad页面，其中我成功了。但我也希望在另一个视图中看到这些广告ad.blade.php。我愿意在post.blade.php中创建所有帖子，然后在ad.blade.php中访问其数据。

但是当我去ad.blade.php时。它给出了错误的 ErrorException 未定义的变量：帖子（查看：E：\ mobile \ resources \ views \ ad \ ad.blade.php）

您忘了将Posts变量传递到ad视图，在控制器中执行此操作：

    public function StorePost(Request $request)
{  
    $this->validate($request, [
        'title' => 'required',
        'name' => 'required',
        'email' => 'required|email',
        'contact' => 'required',
        'model' => 'required',
        'city' => 'required',
         'description' => 'required',   ]);



     $destinationPath = 'public/dist/pictures';

    if (Input::hasFile('image'))
    {
        $file = Input::file('image');
        $file->move('public/dist/pictures', 
                          $file->getClientOriginalName());
    }


    Post::create($request->all());
    $posts = Post::all();

    return view('ad.ad',compact('name','posts'));


}

使用Laravel中的Form将数据从一个视图传递到另一个视图
