php - 在我的控制器中声明更多数据库时，Laravel 表单验证不起作用

问题描述

我声明了一个包含数据库的变量，以便刀片可以选择，但是这样做时，验证不起作用。请帮我。非常感谢。

this is the variable I call in the database to use select in the blade.

public function new_department(){
    //return view('admin.new-department');

    $manage_faculties=DB::table('faculties')->orderBy('id','asc')->get();

    $all_manage_faculties=view('admin.new-department')->with('manage_faculties', $manage_faculties);

    return view('layouts.master')->with('admin.new-department', $all_manage_faculties);
}

Here is the validation I use in the insert information and database.

 public function save_new_department(Request $request){
    $data = [];
    $data['department_name'] = $request->input('department_name');
    $data['description'] = $request->input('description');
    $data['faculty_id'] = $request->input('faculty_name');


    if($request->isMethod('post')){
        $validator = Validator::make($request->all(), [
            'department_name' => 'required|min:3|max:100|unique:departments',
            'description' => 'required|max:500',
        ]);

        if ($validator->fails()) {
            return back()->with('toast_error', $validator->messages()->all()[0])->withInput();
        }

        DB::table('departments')->insert($data);
        return redirect('/admin/departments/new')->withSuccess('Post Created Successfully!');
    }

}

display it in the blade

输入数据后无论真假，都不可能在屏幕上报错。输入数据后无论真假，都不可能在屏幕上报错。
