【问题标题】：Passing data from one view to another view using Form in Laravel使用 Laravel 中的 Form 将数据从一个视图传递到另一个视图

【问题描述】：

我已经成功发布了一个广告页面。但我也想在另一个视图 ad.blade.php 中看到这些广告。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。

但是当我转到 ad.blade.php 时。它给出了错误 错误异常未定义变量：posts（查看：E:\mobile\resources\views\ad\ad.blade.php）

【解决方案1】：

您忘记将 Posts 变量传递给您的 ad 视图，请在您的控制器中进行：

    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'));


}
