Laravel 5.6中的验证

Question

这个问题已经问过了，但这并不能解决我的问题。

我已经尝试在我的laravel project中使用验证。但它不工作这是我的代码

$rules = array(
'coupon_title'          => 'max:10',
'coupon_type_id'        => 'numaric',
'expiry_start_date'     => 'required|before_or_equal:expiry_end_date',
'expiry_end_date'       => 'required',
);
$messages = [
'before_or_equal'    => 'The :attribute must be smaller than the End Date',
'before'    => 'The :attribute must be Greater than the Interview Start Date',
'after'    => 'The :attribute must be Greater than the Interview End Date',
'after_or_equal'    => 'The :attribute must be Greater than the Start Time',
//'max' => 'asdasd'
];
$validator = Validator::make($request->all(), $rules, $messages);
if ($validator->fails()) 
{
$messages = $validator->messages();
return response()->json(['message'=>$messages],401);
}

在我的代码中，只有expiry_start_date字段经过验证。但CCD_ 3和CCD_。

您需要将numaric拼写为numeric，并在验证规则中添加nullable关键字

'coupon_title'          => 'string|max:10|nullable',
'coupon_type_id'        => 'numeric',

还可以为numeric和max添加自定义消息

$messages = [
'before_or_equal'    => 'The :attribute must be smaller than the End Date',
'before'    => 'The :attribute must be Greater than the Interview Start Date',
'after'    => 'The :attribute must be Greater than the Interview End Date',
'after_or_equal'    => 'The :attribute must be Greater than the Start Time',
'max' => 'The :attribute has crossed the limit',
'numeric' => 'The :attribute must have numeric value'
];
