How to Pre-Fill Fields with Joomla User Data in Shack Forms

Documentation for Joomla 3

Shack Forms allows you to automatically pre-fill certain fields with the data of your Joomla users. Such fields are:

Name: Shack Forms fills this name with the name of the logged user.
Email: Shack Forms fills this name with the email address of the logged user.
Username: Shack Forms fills this name with the email address of the logged user.

This is how it works:

Your Joomla user logs into your Joomla site. They then open a Shack Forms module. This module then automatically populates those fields of the form (if they exist) with the user data.

Here is a screenshot with such a form pre-filled with the name, email address, and username of the logged-in Joomla user:

Here is how to set this up.

In your Joomla administrator panel, open up the required Shack Forms module.
Click the "Theme" tab:

click the theme tab

Scroll down to the group of settings "Fields options" as you can see in the next image. Set the "Auto fill in Joomla User" parameter to "Yes":

set autofill in joomla user to yes

Note: If the option is set to "Hide user data if logged in", it acts like "Yes", except it hides the fields with "display:none". This comes from applying the CSS class pweb-hide-user.

Click "Save" or "Save & Close" to save your changes.
Visit your form at the front end of your Joomla site as a logged-in user. You should see the fields automatically populated with the data of the logged-in user, as on the screenshot at the top of this document.
