React-hook-form doesn’t recognize input value

If you are using React-hook-form and facing an issue where it doesn’t recognize the input value, don’t worry, you are not alone. This problem can occur due to a few different reasons, but fortunately, there are multiple solutions available.

Solution 1: Registering the input

One possible reason for React-hook-form not recognizing the input value is that you might have forgotten to register the input with the form. To fix this, make sure to use the register method provided by React-hook-form.

import React from 'react';
import { useForm } from 'react-hook-form';

function MyForm() {
  const { register, handleSubmit } = useForm();

  const onSubmit = (data) => {
    console.log(data);
  };

  return (
    

      
      Submit
    
  );
}

In the above code snippet, we are using the register method to register the input field with the form. This allows React-hook-form to recognize the input value and include it in the form data when submitted.

Solution 2: Providing a default value

Another reason for React-hook-form not recognizing the input value is that you might not have provided a default value for the input. In such cases, React-hook-form assumes the initial value of the input to be undefined. To fix this, you can provide a default value using the defaultValue prop.

import React from 'react';
import { useForm } from 'react-hook-form';

function MyForm() {
  const { register, handleSubmit } = useForm();

  const onSubmit = (data) => {
    console.log(data);
  };

  return (
    

      
      Submit
    
  );
}

In the above code snippet, we have provided a default value of “Default Value” for the input using the defaultValue prop. This ensures that React-hook-form recognizes the input value even if the user doesn’t explicitly change it.

Solution 3: Using the watch method

If you are still facing issues with React-hook-form not recognizing the input value, you can use the watch method provided by React-hook-form to manually watch for changes in the input value.

import React from 'react';
import { useForm, watch } from 'react-hook-form';

function MyForm() {
  const { register, handleSubmit } = useForm();
  const myInputValue = watch('myInput');

  const onSubmit = (data) => {
    console.log(data);
  };

  return (
    

      
      Submit
      Input Value: {myInputValue}
    
  );
}

In the above code snippet, we are using the watch method to watch for changes in the input value. By passing the name of the input field to the watch method, we can access its current value and include it in the form data when submitted.

With these solutions, you should be able to resolve the issue of React-hook-form not recognizing the input value. Remember to register the input, provide a default value if necessary, and use the watch method to manually watch for changes in the input value.

Happy coding!
