Php Can'；t将文件上载到服务器Laravel

我试图添加一些产品到我的数据库，我必须上传这个产品的照片。我已经创建了一个控制器和视图，但当我单击“创建”时，出现了一个错误

Unable to create the "/uploads/products/" directory

这是我的代码：
控制器

public function postAddProduct(){
    $destinationPath = '';
    $filename        = '';
    $newId = Product::max('id')+1;
    $validator = Validator::make(Input::all(), array(
        'name' => 'required',       
        'description' => 'required',            
        'partner_link' => 'required',
        'image'=>'required'
    ));
    if (Input::hasFile('image')) {
        $file            = Input::file('image');
        $destinationPath = public_path().'/uploads/products/';
        $filename        = $newId.'.'.$file->getClientOriginalExtension();
        $uploadSuccess   = $file->move($destinationPath, $filename);
    }

    if($validator->passes()){
        $product = new Product;
        $product->name = Input::get('name');
        $product->description = Input::get('description');
        $product->category_id = Input::get('category');
        $product->partner_link = Input::get('partner_link');
        $product->photo = $filename;
        $product->save();   

        return Redirect::back();
    }else{
        return Redirect::back()->withErrors($validator)->withInput();
    }



}

视图：

---

听起来好像

public/uploads/products

文件夹不存在，Laravel没有创建它的权限

---

尝试手动创建文件夹，通过运行

chmod 775 public/uploads/products

确保Laravel对其具有可写访问权限。然后重试代码。

我将此文件夹设置为公用\u html/因为此应用程序位于服务器上。您的Laravel项目的路径是什么？如何将public_html集成到Laravel中？例如，符号链接公用文件夹？或者整个Laravel结构进入公共html，例如公共html/app、公共html/bootstrap等等？不，这是我的公共html应用程序结构我有所有的js/css/图像文件我的引导程序看起来像这样

return数组（'app'=>\uuuuuuu DIR./../app'，'public'=>\uuuuuu DIR./../public'，'base'=>\uuuu DIR./'/../storage'=>\uuuuu DIR./../app/storage'，）抱歉设置样式。请尝试
chmod 775 public\u html/uploads/products
。或777，如果775不工作。
{{ Form::open(array('url'=>'user/admin/products/addd', 'files' => true, 'class'=>'col-md-4', 'style'=> 'float:none; margin: 0 auto', 'id'=>'register-form')) }}
