Why isn't the Formik `touched` property being populated?


I'm making a form with React, Formik, react-bootstrap, and yup for validation. I am trying to display validation errors, but the touched property is not being populated with the fields.

const schema = yup.object({
  name: yup.string().required(),
  email: yup
    .string()
    .email()
    .required(),
});

const ChildForm = props => {
  const { child: { name = '', email = '' } = {} } = props;
  const submitHandler = ({name, email}) => console.log(name, email);

  return (
    <Formik
      validationSchema={schema}
      onSubmit={submitHandler}
      initialValues={{ name, email }}
      render={({ handleSubmit, handleChange, values, touched, errors }) => 
      {
        console.log('touched: ', touched);
        return (
          <Form noValidate className="mt-4" onSubmit={handleSubmit}>
            <Form.Row>
              <Form.Group as={Col} controlId="name">
                <Form.Label>Full Name</Form.Label>
                <Form.Control
                  name="name"
                  required
                  value={values.name}
                  onChange={handleChange}
                  isValid={touched.name && !errors.name}
                  isInvalid={touched.name && errors.name}
                  type="text"
                  placeholder="Your child's name"
                />
                <Form.Control.Feedback>Looks good!</Form.Control.Feedback>
                <Form.Control.Feedback type="invalid">
                  {errors.name || 'Please enter your child\'s name'}
                </Form.Control.Feedback>
              </Form.Group>
            </Form.Row>
            <Form.Row>
              <Form.Group as={Col} controlId="email">
                <Form.Label>Email Address</Form.Label>
                <Form.Control
                  name="email"
                  required
                  value={values.email}
                  onChange={handleChange}
                  isValid={touched.email && !errors.email}
                  isInvalid={touched.email && errors.email}
                  type="text"
                  placeholder="Your child's email address"
                />
                <Form.Control.Feedback>
                  No spam, we promise!
                </Form.Control.Feedback>
                <Form.Control.Feedback type="invalid">
                  {errors.email || 'Please enter a valid email address'}
                </Form.Control.Feedback>
              </Form.Group>
            </Form.Row>
            <Form.Row className="float-right">
              <Button variant="success" onClick={handleSubmit}>
                <Icon icon={faSave} />
                &nbsp; Submit
              </Button>
            </Form.Row>
          </Form>
        );
      }}
    />
  );
}

What am I doing wrong here? The console.log(touched) always shows an empty object.


Solution

  • @djheru Your solution is correct because Formik sets touched flags on blur event instead of on change. Here is Formik author comment about this: You have to call Formiks handleBlur to notify Formik that blur event has been triggered - so yes, these handlers are needed.
