Hi @hoaanhtuc. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- You can achieve this by using conditional validation with Yup, a JavaScript schema builder for value parsing and validation. In the validation schema, you can use the when method to add a condition to a field. The when method allows you to change the validation schema of a field based on the value of another field. Here's an example:

const schema = Yup.object().shape({
  time: Yup.string()
    .required('This field is required'),
  timeUnit: Yup.string().when(
    "time",
    (time: string, schema: Yup.StringSchema) => {
      return time ? schema.required('This field is required') : schema
    }
  ),
});

const schema = Yup.object().shape({
  time: Yup.string()
    .required('This field is required'),
  timeUnit: Yup.string().when(
    "time",
    (time: string, schema: Yup.StringSchema) => {
      return time ? schema.required('This field is required') : schema
    }
  ),
});

In this example, timeUnit is required only if time is filled. If time is not filled, timeUnit is not required. You can find more information about this in the extracted source (https://discord.com/channels/837692625737613362/1158246064630009947). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

Hello @hoaanhtuc
https://ant.design/components/input you can check ant design documentation

<Form {...formProps}> <Row gutter={24}> <Col span={24}> <InputForm label="time" name="time" /> </Col> <Col span={24}> <SelectTimeUnit required={formProps?.form?.getFieldValue("time") ? true : false} /> </Col> </Row> </Form> This is the form and log value I receive.

absent-sapphire•15mo ago

what is <SelectTimeUnit /> implementation ?

dependent-tanOP•15mo ago

I want when entering a value into time, timeUnit will be required, and vice versa

dependent-tanOP•15mo ago

formProps?.form?.getFieldValue("time") is not working

absent-sapphire•15mo ago

yes. form?.getFieldValue("time") comes from Antd design and does not sync with UI. you can use https://ant.design/components/form#formusewatch or you can use react state to conditionaly render

dependent-tanOP•15mo ago

const timeValues = Form.useWatch("time", formProps); great, it worked without state
