How to dynamically populate Gravity Forms

Online forms have made information-sharing and data collection more convenient than ever — but what if you could improve them even more? That’s where “dynamic population” comes in.

Dynamic form population uses predefined rules or external data sources to automatically fill out specific form fields, creating a more streamlined and user-friendly experience. Dynamic population eliminates the need for users to manually input repetitive information, saving time and reducing the potential for human error. It also enables integration with other software for seamless data retrieval and input, increasing the overall efficiency of forms.

One of the most popular online form builders to feature dynamic population capabilities is Gravity Forms. Here’s a comprehensive guide on how to dynamically populate Gravity Forms (as well as an alternative solution that provides similar benefits with a less-complicated setup).

How to dynamically populate Gravity Forms

With the Gravity Forms dynamic population feature, users can automatically populate form fields with specific values using methods like query strings, shortcode, and hooks. But before you can dynamically populate your form, you must first configure it for dynamic population. Here’s how:

  1. Create a new Gravity Form.
  2. Click the field that you want to populate.
  3. Select the Allow Field to be Populated Dynamically checkbox.
  4. In the new Parameter Name text fields, enter the values you would like to use as a reference so the system knows which field to populate.

Read on for next steps on how to dynamically populate Gravity Forms using either query strings, shortcode, or hooks.

1. Query string

The query string method is especially useful for condensing multiple forms into one. For example, if your company has multiple points of contact, you might be tempted to create contact forms for each employee. With dynamic population, though, you can add their individual email addresses as parameters to the URL for a single contact form, then set up an email field in the form that dynamically populates that email address. Here’s how to set it up:

  1. Using this query string template URL:, modify to match your site’s URL.
  2. Modify the form-url text to match your Gravity Form URL.
  3. Modify the ?your_parameter text to match the name of the parameter name you created previously.
  4. Modify the value text to match the text you would like to automatically populate in your form field.

2. Shortcode

Alternatively, using shortcode to dynamically populate Gravity Forms is great when you need to use the same form to collect different values depending on where the form is displayed. For example, if you create an event registration form but have multiple events to collect registrations for, you can use shortcode to change the event name in the form to match the page it’s posted on.

To use the shortcode method, follow these steps:

  1. Add the field_values parameter to your Gravity Form. The code will display like this: 
gravityform id="1" field_values="parameter_name1=value1¶meter_name2=value2"

This code allows your form to accept multiple dynamic population parameters separated by an ampersand. 

  1. From there, modify the parameter_name1 and parameter_name2 text to match the name of the parameters you previously defined.

3. Hooks

Using hooks enables more flexible dynamic population than either the query string or shortcode options. However, it’s also the most complex technique of the three, as it involves some PHP coding. Here’s what to do:

  1. Open the functions.php file of your active theme.
  2. Add this sample code to the file:

add_filter( 'gform_field_value_your_parameter', 'my_custom_population_function' );
function my_custom_population_function( $value ) {
return 'boom!';
  1. Modify the your_parameter text in line 1 to match the parameter name you previously defined.
  2. Modify the boom! text in line 3 to match the name of the value you would like to display that parameter.
