FormError

Form

Renders an element that shows an error message. The children will automatically display the error message defined in the store.

Code examples

const form = useFormStore({
  defaultValues: {
    email: "",
  },
});

form.useValidate(() => {
  if (!form.values.email) {
    form.setError(form.names.email, "Email is required!");
  }
});

<Form store={form}>
  <FormLabel name={form.names.email}>Email</FormLabel>
  <FormInput name={form.names.email} />
  <FormError name={form.names.email} />
</Form>
const form = useFormStore({
  defaultValues: {
    email: "",
  },
});

form.useValidate(() => {
  if (!form.values.email) {
    form.setError(form.names.email, "Email is required!");
  }
});

<Form store={form}>
  <FormLabel name={form.names.email}>Email</FormLabel>
  <FormInput name={form.names.email} />
  <FormError name={form.names.email} />
</Form>
