Question

在我的项目中。所有挂载可能是int或float或者甚至是double.in数据库量列类型是varchar并且对于每个用户选择量我有简单的限制，例如，数量必须大于某个值而少于某个值。但是我在laravel中得到了错误验证。

$ps = DB::table('merchant_web_service')->whereCustomerKey($request->input('customer_key'))->first();

/* $ps->minimum_range_buy is 5 and $ps->maximum_range_buy is 10*/

$validate_amount      = Validator::make($request->all(), 
            ['amount' => "required|min:$ps->minimum_range_buy|max:$ps->maximum_range_buy"]);

验证器错误是：

"The amount must be at least 10 characters."

我的测试金额值：1000,100.1

Answer 1

试试这个

$rules = [
'your_field' => 'required|regex:/^\d*(\.\d{2})?$/'
]

Answer 2

由于您没有为输入数据类型指定任何规则，因此将其验证为字符串。请尝试numeric和between规则。

$validate_amount = Validator::make($request->all(), 
     ['amount'=>
      "required|numeric|between:$ps->minimum_range_buy,$ps->maximum_range_buy"
     ]);

Laravel将int或float数字验证为字符串
