为什么验证消息未显示在required_if中？

Question

如果用户为“ registration_type_price”字段输入的值大于“ 0”，我希望“ paying_mb”，“ payment_c”和“ invoice_issuer”字段为必填项。

但是它不起作用，验证消息未显示为“ required_if：registration_type_price，>，0'”。你知道为什么吗？

$rules =  [
    ...
    'payment_mb' => 'required_without:payment_c|required_if:registration_type_price,>,0',
    'payment_c' => 'required_without:payment_mb|required_if:registration_type_price,>,0',

    'invoice_issuer' => 'required_if:registration_type_price,>,0',
];

$customMessages = [
    ...
    'payment_mb.required_if' => 'The field payment methods is mandatory.',
    'payment_c.required_if' =>  'The field payment methods is mandatory.',

    'invoice_issuer.required_if' => 'The field invoice issuer is mandatory..'

];

$this->validate($request, $rules, $customMessages);

尝试这个

$("#personal_detail_form").validate({
     rules: {
        full_name: {
            lettersonly: true
        },phone_number : {
            number : true,
            minlength:10,
            maxlength:10
        },city : {
            lettersonly : true
        },pin_code : {
            digits : true,
            minlength:6,
            maxlength:6 
        },
