Set Row Headers & Receive Tabular Data in Gravity Form List


The Challenge

How can we receive complex tabular data in a Gravity Form?

Tabular data via Gravity Form multi-column list field

For example, I recently had need of receiving the above information for a service profile. In this post, we’ll walk through how you can setup the native GF list field to meet this need.

The Tools

Apart from Gravity Forms, there are no other special tools needed to setup this solution.

The Solution

Add List Field & Define Columns

Our first step is to add a list field in our form. Enable multiple columns and add headings for each column. Take note of the heading you give the first column as you will need this to auto-populate the row headings.

Enable Dynamic Population

Under the Advanced tab, you will check to Allow field to be populated dynamically. Be sure to set a parameter name for dynamic population. You’ll need this later, too.

Dynamically Populate Row Headers

This is where the good stuff begins to happen. In order to populate the row headers, we will utilize the gform_field_value_$parameter_name filter. Using code from this gist (shown below), ensure you’ve properly set the filter name according to the dynamic population parameter name you set for the field. Then set the list array according to the column you want to populate.

  • The key in each row’s array element must exactly match the header you set for the column.
  • The value will define the row header you want for each row.

Set Row Headers As readonly & Prevent Row Removal

Finally, we add an HTML field at the beginning of our form which will contain some small javascript to prevent users changing the row headers or removing our rows. This script can also be found in the gist. Be sure to set your specific field ID in the selector. This script also modifies the CSS of these row headers (so that they don’t appear as a fillable field) and the tabindex attribute (so that they are removed from the tab flow of the form).

Wrapping It Up

That should do it. You’re now setup to receive tabular data via your Gravity Form. Questions? Connect with me @uamv or @typewxyz.
