Add a react-bootstrap alert to handleSubmit in Formik
Use state and conditional rendering. Instead of returning a component set state to a variable, in your render use conditional rendering to check if the value is true.
handleSubmit = (formState, { resetForm }) => {
// Now, you're getting form state here!
const payload = {
...formState,
role: formState.role.value,
createdAt: firebase.firestore.FieldValue.serverTimestamp()
};
console.log('formvalues', payload);
fsDB
.collection('register')
.add(payload)
.then(docRef => {
resetForm(initialValues);
})
.then(e => this.setState({ alert: true }))
.catch(error => {
console.error('Error adding document: ', error);
});
};
In your render
render() {
...
return(
....
{this.state.alert && <AlertDismissible />}
...
)
}
