I am beginning to learn I want to make some queries, I want to create only one input that is editable at the front of the page.
<?php acf_form(
array('html_after_fields' => '<input type="text" id="id_whatsapp"
name="acf[n_whatsapp]" value="acf[n_whatsapp]">',));?>
I have only this small code, if you could help me to leave it functional for, I do not find a practical and functional example
If you are attempting to create your own form field that uses and acf field then you must use the field key instead of the field name.
name="acf['field_XXXXXXX']"
