Key name empty in field validation response

Package version v9:

Question

The validation error does not show the key name i.e. myEmail.
How can I populate key name also for field validation?

Code sample, to showcase or reproduce:

func validateVariable() {

	myEmail := "joeybloggs.gmail.com"

	errs := validate.Var(myEmail, "required,email")

	if errs != nil {
		fmt.Println(errs) // output: Key: "" Error:Field validation for "" failed on the "email" tag
		return
	}

	// email ok, move on
}

Same exact problem

@vishal3152 @ianaz Unfortunately is no way in Go using reflection to get the variable name, I looked at everything trying to find a way when I wrote the lib.

this is a very important feature

@1011875777 if you know of a way to dynamically extract a variables name at runtime I’d be happy to add it.

Been struggling with the same problem too.

I planned on working around this and specify the field manually in some custom Validate function; but keep using the tag validation & translation functionality from this lib.

Sadly I got stuck, mainly because most fields are private (e.g. transTagFuncs). Working around all that would require quite a bit of scaffolding.

I'll probably validate these exceptions now manually, given most of the validation rules are struct-based.
(my validation problem involves code-generated golang files which I don't want to change)

could we pass the key when call validate.Var()?

	errs := validate.Var(myEmail, "email", "required,email")

[deankarn]

errs := validate.Var(myEmail, "email", "required,email")

This assumes a single variable and not an array or slice. Will look into the possibility though.
