ACF creating multi field, custom field type

Question

I have created custom field type following this documentation https://www.advancedcustomfields.com/resources/creating-a-new-field-type/ and I have below fields:

YouTube ID(input type text)
Submit Button(input type submit)
Title(input type text)
Description(input type text)
Thumbnail URL(input type text)
Upload Date(input type text)
Duration minute(input type number)
Duration seconds(input type number)

I have saw this question, Advanced Custom Fields – Custom Field Type with multiple inputs and ACF: Creating Custom Field Type store two values. I am expecting that I could do it this way when setting the fields.

<input type="text"
  name="<?php echo esc_attr($field['name']['youtube-id'])?>"
  value="<?php echo esc_attr($field['value']['youtube-id'])?>"
/>
 <input type="text"
  name="<?php echo esc_attr($field['name']['youtube-title'])?>"
  value="<?php echo esc_attr($field['value']['youtube-title'])?>"
/>
...

But this give me an error:

$field['name'] is a string. Thus, doing $field['name']['foo'] or the equivalent 'string'['foo'] is illegal in PHP and will raise the error. You may want to consider something like this instead:

<input type="text"
  name="<?php echo esc_attr($field['name']); ?>"
  value="<?php echo esc_attr($field['value']); ?>"
/>

Where is your other field? How does it integrate with this field? – Wongjn Apr 29 '23 at 12:56
you can see it, in the render field method, i have multiple fields – luna moonfang Apr 29 '23 at 12:58
You'd want to look at making `$field['value']` an array, and then have the values like `$field['value']['foo']`. – Wongjn Apr 29 '23 at 12:59
how do i do this? – luna moonfang Apr 29 '23 at 13:01
