Hi @Koli14
Yes, it is the name which is used to post data.
As mentioned above, if you want to send 2 textarea’s in the same name, you will need to use square brackets to tell the browser it is an array of information.
For example, you want the output to be:
<textarea name="fields[field_123][textarea_1]"></textarea>
<textarea name="fields[field_123][textarea_2]"></textarea>
