Hello,
I’ll be happy to help you.
You can implement auto-fill using integration with the Contact Form 7 plugin.
Bellow are steps to set it up:
1. Install and activate the Contact Form 7 plugin.
2. In CF7 create a new form with the following content:
<p><label for="wbk-name">Your First Name (required)</label>[text* wbk-name class:wbk-text id:wbk-name default:user_display_name]</p>
<p><label for="wbk-email">Your Email (required)</label>[text* wbk-email class:wbk-text id:wbk-email default:user_email]</p>
<p><label for="wbk-phone">Your phone (required)</label>[text* wbk-phone class:wbk-text id:wbk-phone]</p>
<p><label for="wbk-comment">Your comment</label>[textarea wbk-comment class:wbk-textarea id:wbk-comment]</p>
3. Set the newly created form in the Form settings of the service.
Unfortunately, this solution will not work for the phone fields, because the phone field is not default WordPress user field.
