如何使用 Laravel 5.2 以相同的方法添加和更新表行

Question

我需要使用 Laravel 5.2 在我的控制器中以一種方法插入數據並更新表行。 我的表名是“權限”。 這是我的方法：

public function addPermission(Request $request, $id,  Permission $permission)
{
    if ($permission = Permission::findOrFail($id));{
     $this->validate($request, [
        'status'   => 'required'


    ]);

    $permission = new Permission;

    $permission->status = $request->input('status');
    $permission->project_id       = $id;

    $permission->collaborator_id =  $request->input('cid');

    $values = $request->all();
    $permission->fill($values)->save();

    return redirect()->back()->with('info','Permission has been updated to your Collaborator successfully');
    }
    else  {

     $this->validate($request, [
        'status'   => 'required'


    ]);

    $permission = new Permission;

    $permission->status = $request->input('status');
    $permission->project_id       = $id;

    $permission->collaborator_id =  $request->input('cid');
    $permission->save();
    return redirect()->back()->with('info','Permission has been added to your Collaborator successfully');

   }  
}

我收到以下錯誤

語法錯誤，意外的“else”（T_ELSE）

我究竟做錯了什么？

Answer 1

對於語法錯誤

if ($permission = Permission::findOrFail($id)); { ......

只需刪除“;”

if ($permission = Permission::findOrFail($id)) { .....
