Why does requiredIf need at least 2 values?

[budimanjojo]

I have been scratching my head because requiredIf doesn't work until I looked at the code:

validate/validators.go

Lines 193 to 195 in 9b1446b

	if len(kvs) < 2 {
	return false
	}

What is the reason behind this?

hi @budimanjojo

required_if:anotherfield,value,... The field under validation must be present and not empty if the anotherField field is equal to any value.

anotherField + value,... so, len should >= 2

[budimanjojo]

anotherFieldis type of interface{} isn't it? The function accepts valas the interface which is anotherFieldand 1 or more kvswhich is value which is string. Because I can't get required_if:anotherField,value to work, but it works when I set required_if:anotherField,value,value

Can you provide a code example?

[budimanjojo]

Try this:

package main

import (
	"fmt"

	"github.com/gookit/validate"
)

type Test struct {
	Field1 string 
	Field2 string `validate:"requiredIf:Field1,value,value"`
}

func main() {
	test := &Test{Field1: "value", Field2: ""}
	v := validate.Struct(test)
	if ! v.Validate() {
		fmt.Println(v.Errors)
	}


}

Notice that I use validate:"requiredIf,Field1,value,value" because it doesn't work if I put value once.
