5 Ways to Use React Hook Form Checkbox

Now that we've covered the basics of React Hook Form, let's dive into five ways to use React Hook Form checkbox:

1. Basic Checkbox Example

Here's an example of a basic checkbox using React Hook Form:

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

function MyForm() {
  const { register, handleSubmit } = useForm();
  const onSubmit = async (data) => {
    console.log(data);
  };

  return (
    

      
        
        Check me!
      
      Submit
    
  );
}

In this example, we use the useForm hook to create a form context. We then use the register function to register the checkbox field. Finally, we define an onSubmit function to handle form submission.

2. Multiple Checkboxes

Here's an example of multiple checkboxes using React Hook Form:

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

function MyForm() {
  const { register, handleSubmit } = useForm();
  const onSubmit = async (data) => {
    console.log(data);
  };

  return (
    

      
        
        Option 1
      
      
        
        Option 2
      
      
        
        Option 3
      
      Submit
    
  );
}

In this example, we use the register function to register multiple checkbox fields with the same name (checkboxes). We also define a value prop for each checkbox to specify the value that should be submitted.

3. Disabled Checkboxes

Here's an example of disabled checkboxes using React Hook Form:

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

function MyForm() {
  const { register, handleSubmit } = useForm();
  const onSubmit = async (data) => {
    console.log(data);
  };

  return (
    

      
        
        Check me!
      
      Submit
    
  );
}

In this example, we add a disabled prop to the checkbox field to disable it. This prevents the user from interacting with the checkbox.

4. Checked Checkboxes

Here's an example of checked checkboxes using React Hook Form:

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

function MyForm() {
  const { register, handleSubmit } = useForm();
  const onSubmit = async (data) => {
    console.log(data);
  };

  return (
    

      
        
        Check me!
      
      Submit
    
  );
}

In this example, we add a defaultChecked prop to the checkbox field to check it by default.

5. Validation

Here's an example of validating checkboxes using React Hook Form:

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

function MyForm() {
  const { register, handleSubmit, errors } = useForm();
  const onSubmit = async (data) => {
    console.log(data);
  };

  return (
    

      
        
        Check me!
      
      {errors.checkbox && 
Checkbox is required!
}
      Submit
    
  );
}

In this example, we use the register function to register the checkbox field with a validation rule (required: true). We also define an errors object to display error messages.
