在表单上创建附加验证，注册默认的laravel

Question

This users(mstanggota) table:

 Schema::create('mstanggota', function (Blueprint $table) {
            $table->increments('id');
            $table->string('no_anggota',10);
            $table->string('name');
            $table->string('email')->unique();
            $table->string('password');
            $table->rememberToken();
            $table->timestamps();
        });

Mstbeasiswas table:

Schema::create('mstbeasiswas', function (Blueprint $table) {
            $table->increments('id');
            $table->string('no_anggota',10)->unique();
            $table->string('nm_anak',25);
            $table->string('kt_lahir',25);
            $table->date('ttl');
            $table->String('nm_skl',50);
            $table->String('st_pend',6);
            $table->String('lbg_pend',6);
            $table->String('prov_skl');
            $table->String('jenkel',9);
            $table->integer('k_umum');
            $table->integer('k_khusus');
            $table->integer('score')->nullable();
            $table->boolean('status')->default(0);
            $table->string('ket',250)->nullable();
            $table->string('img1',50)->nullable();
            $table->string('img2',50)->nullable();
            $table->string('img3',50)->nullable();
            $table->timestamps();
        });

I would like to make an additional validation. If no_anggota does not exist on table mstbeasiswas then the user cannot register, what is there that could help me? :(

register form view->

Answer 1

Laravel surely works fine with no matter which way you've chose. Both traditional request and AJAX request are accepted.

You can make your validation in controllers or creating another class. I prefer the second one in this situation to avoid let controller terrible and unclear.

I assume you've read the chapter of Validation.

1. making a class by artisan command

$ php artisan make:request UserRegisterRequest

2. editing validation rules (change with yours)

/**
 * Get the validation rules that apply to the request.
 *
 * @return array
 */
public function rules()
{
    return [
        'name' => 'required|max:10',
        'nickname' => 'required|max:20',
        'email' => 'required|email|max:255|unique:users',
        'password' => 'required|min:6',
        'permission' => 'required|numeric',
    ];
}

3. set names for each field (change with your language)

public function attributes ()
{
    return [
        'name' => '姓名',
        'nickname' => '綽號',
        'email' => 'E-Mail',
        'password' => '密碼',
        'permission' => '權限',
    ];
}

4. response if error

public function response(array $errors) {
    return response()->json([
        'status' => false,
        'errors' => $errors
    ]);
}

5. validate each request before getting in the controller

public function account_add(UserRegisterRequest $request) {

    // pass the validation
}

The difference between traditional request and AJAX is that you can return redirection with errors or JSON. In this case, we've chose JSON instead of redirection. So that you can handle your errors at front-end.
