package main

import (
	"fmt"

	"github.com/gookit/validate"
)

func main() {
	type user struct {
		Name string `validate:"required"`
		Age  int    `validate:"required_if:Name,lee"`
	}

	u := &user{Name: "lee"}
	v := validate.Struct(u)

	if v.Validate() { // validate ok
		// do something ...
	} else {
		fmt.Println(v.Errors)               // all error messages
		fmt.Println(v.Errors.One())         // returns a random error message text
		fmt.Println(v.Errors.OneError())    // returns a random error
		fmt.Println(v.Errors.Field("Name")) // returns error messages of the field
	}
