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

Shack Forms allows you to automatically pre-fill certain fields with data of your Joomla users. Those 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 and email address 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 frontend 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.
