如何在 Laravel 6 中保存布尔值？

Question

我有

迁移文件：

public function up()
{
    Schema::create('bookings', function (Blueprint $table) {
        $table->bigIncrements('id');
        $table->unsignedBigInteger('user_id');
        $table->string('name');
        $table->string('phone');
        $table->boolean('wifi');
        $table->string('address');
        $table->text('desc');
        $table->timestamps();
    });
}

BookingController.php的store方法：

public function store()
    {
        $booking = new Booking();
        $booking->user_id = 1;
        $booking->name = request('name');
        $booking->phone = request('phone');
        $booking->wifi = request('wifi');
        $booking->address = request('address');
        $booking->desc = request('desc');
        $booking->save();

        return redirect('/bookings');
    }

create.blad.php 是 wifi 复选框的一部分：

<div class="field">
   <label for="wifi" class="label">Wi-Fi</label>
   <div class="control">
      <input type="checkbox" class="form-check" name="wifi" id="address">
   <div>
</div>

当我尝试创建记录时，出现错误：

1) 我正在尝试将值保存为 FALSE:

Illuminate\Database\QueryException SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'wifi' cannot be null (SQL: insert into bookings (user_id, name, phone, wifi, address, desc, updated_at, created_at) values (1, Dragon, 12341234, ?, asdfasdfasdkf hsadfasdf, asdfasdfas, 2020-02-27 07:10:55, 2020-02-27 07:10:55))

2) 当我选中 Wi-Fi 复选框时（真值）

Illuminate\Database\QueryException SQLSTATE[22007]: Invalid datetime format: 1366 Incorrect integer value: 'on' for column kaganat.bookings.wifi at row 1 (SQL: insert into bookings (user_id, name, phone, wifi, address, desc, updated_at, created_at) values (1, Dragon, 12341234, on, asdfasdfasdkf hsadfasdf, asdfasdfasdfsafaa, 2020-02-27 07:17:15, 2020-02-27 07:17:15))

更新：

解决方案：

更新自

$booking->wifi = request('wifi');

到

$booking->wifi = request()->has('wifi');

Answer 1

您可以使用 has 方法检查值是否已提交，因此您可以插入 true 或 false。

您可以在此处阅读文档：https://laravel.com/docs/6.x/requests#retrieving-input

所以它必须类似于 $request->has('wifi')。如果请求中存在该值，则 has 方法将为 return true。如果此值为真，则可以将 true 分配给该字段，否则为 false。这就是我的方法。
