can somebody help me ?

Hey @youcandoit95

can you confirm you have the latest version of the code, the validation was added recently?

[cwoodcock]

Doesn't look like this is the issue the OP is facing, but in case somebody searches and lands here it might save them a bit of head scratching. You can get an 'Undefined validation function' panic if there's whitespace in the tag e.g. validate:"required, foo".

@youcandoit95 did updating help?

closing due to no response.

I'm encountering the same problem.

Here is what I guess would be the problem

• I'm updating my gin custom binding validator in init() method
• in the program main function, I've var validator *validate.Validator, and from there I call
  validate.RegisterValidation(tag, customTag).
  However, my custom tag is not being recognized.

And I'm using gin's binding.

[adonese]

I've fixed it.
You have to, which was clearly written in the validator.v8 -> v9 upgrade, to register your custom functions in func (v *defaultValidator) lazyinit() func.
