Call to undefined function : Laravel 5.1
提问by Tim Lewis
I have a private function as written below in the Controller.
我在控制器中有一个私有函数，如下所示。
private function GetProjects($ProjectStatus) {
return \App\Models\Project\Project_Model
::where('ProjectStatusID', $ProjectStatus)
->where('WhoCreatedTheProject', auth()->user()->UserID)->get();
}
Below is the action method that is using this private function.
下面是使用这个私有函数的操作方法。
public function ClientCancelledProjects() {
$ProjectStatus = \App\Enumeration\Project\ProjectStatus::Cancelled;
$MyProjects = GetProjects($ProjectStatus);
return view("Project.Client.MyProject", array("Projects" => $MyProjects));
}
Below is the Error coming when running the controller.
以下是运行控制器时出现的错误。
Call to undefined function App\Http\Controllers\Project\GetProjects()
调用未定义的函数 App\Http\Controllers\Project\GetProjects()
Somebody knows why this is happening ? I am trying to reuse some lines of code as they are written many times in the Controller.
有人知道为什么会这样吗？我试图重用一些代码行，因为它们在控制器中多次编写。

To access functions in a controller from a function in the same controller, use self:::
要从同一控制器中的函数访问控制器中的函数，请使用self::：
public function ClientCancelledProjects() {
$ProjectStatus = \App\Enumeration\Project\ProjectStatus::Cancelled;
$MyProjects = self::GetProjects($ProjectStatus);
return view("Project.Client.MyProject", array("Projects" => $MyProjects));
}
Note: Self::(uppercase) will work depending on the version of phpinstalled, but for older versions, self::is preferred.
注意：（Self::大写）将根据php安装的版本工作，但对于旧版本，self::首选。

Functions inside of a class are not global functions, and cannot be called that way. You need to use $this->GetProjects()instead.
类内的函数不是全局函数，不能那样调用。你需要$this->GetProjects()改用。
