Following the example here I have a custom input component:
Input.tsx
import React from "react";
export default function Input({label, name, onChange, onBlur, ref}:any) {
return (
<>
<label htmlFor={name}>{label}</label>
<input
name={name}
placeholder="Jane"
onChange={onChange}
onBlur={onBlur}
ref={ref}
/>
</>
);
}
An example of the usage:
import {useAuth} from '../components/AuthContextProvider'
import { useForm, SubmitHandler } from "react-hook-form";
import Input from '../components/Input'
function Subscriptions({ Component, pageProps }: any) {
const { user } = useAuth()
const { register, handleSubmit, formState: { errors } } = useForm<Inputs>();
const onSubmit: SubmitHandler<Inputs> = async data => {
console.log(data, 'data sdfdsg')
}
return (
<>
<form onSubmit={handleSubmit(onSubmit)}>
<Input label="name" {...register('name')}/>
<button type='submit'>Add kid</button>
</form>
</>
)
}
export default Subscriptions
Here's my package version:
"react-hook-form": "^7.34.2"
Any ideas what I'm doing wrong here?
The custom input receives undefined but it works with normal <input />
tags.
I've used the example in a codesandbox and it threw errors about ref
and it suggested using React.forwardRef
, change your custom Input to this:
function Input({ label, name, onChange, onBlur }, ref) {
return (
<>
<label htmlFor={name}>{label}</label>
<input
name={name}
placeholder="Jane"
onChange={onChange}
onBlur={onBlur}
ref={ref}
/>
</>
);
}
const MyInput = React.forwardRef(Input);
export default MyInput;
and by the way, ref
is not part of props
I don't know why the example has it like that, it's necessary to use forwardRef
so it is passed as second argument.
you can see the full example in this codesandbox
