Introduction

Using dynamic population in Gravity Forms allows you to dynamically populate a field with a value (or values ​​depending on the field type). This value can be passed via query strings, shortcode and/or square brackets. This tutorial will give you an example of using each dynamic fill method to dynamically fill a field on your form!

Departure

IMPORTANT : The dynamic fill function uses PHP to retrieve values ​​and fill in form fields. Therefore, it cannot be used on cached pages. This is not a limitation of Gravity Forms, but a consequence of using caching, which prevents PHP code from executing.

Three steps are required to configure the dynamic population:

  1. Specify which field must be completed
  2. Configure how the field should be filled
  3. Determine the value with which the field should be filled

To start, let’s talk about specifying the field to be filled. To specify a field for dynamic filling, simply check the Allow field dynamic filling checkbox in the field’s Advanced tab. This will display a text field titled Parameter Name. The value entered here will serve as a reference for this field so that Gravity Forms knows which field to fill.

Warning : Avoid using a parameter name from this list of WordPress reserved terms.

Una vez que haya ingresado el nom de su parámetro, estará listo para decidir cómo desea completar el campo.

Consultation Padlock

You can complete a campo a través de la cadena de consulta agregando el parámetro de llenado dinámico que especificó para el campo al final de la URL de su formulario junto con su valor personalizado.

1

http: //siteurl.com/form-url/?your_parameter=value

Suponiendo que hay un formulario de gravedad en la página de esta URL, cualquier campo con el nombre de parámetro de población dinámica su_parámetro se completará con el valor valor .

Al elegir el nombre del parámetro para sus campos, asegúrese de evitar el uso de cualquiera de los términos reservados de WordPress . La mejor práctica es usar su propio prefijo para que los nombres de sus parámetros sean únicos. Por ejemplo, use sa_number en lugar de number .

Para preseleccionar campos de casilla de verificación y campos de selección múltiple, proporcione una lista de valores separados por comas. Los valores que se preseleccionarán en los campos basados ​​en opciones distinguen entre mayúsculas y minúsculas.

Se sabe que algunos hosts que utilizan técnicas agresivas de almacenamiento en caché, como WP Engine, almacenan en caché no solo páginas sino también parámetros de cadena de consulta . Por lo tanto, si tiene problemas para que sus campos se llenen dinámicamente, vuelva a verificar que su página y los parámetros de la cadena de consulta no estén almacenados en caché.

¿Cuándo es útil este método?

Supongamos que tiene una lista de agentes inmobiliarios que está mostrando en su sitio web. Cada agente tiene un enlace a un formulario de contacto para que los usuarios puedan contactar a cada agente directamente. En lugar de crear un formulario de contacto separado para cada agente, puede agregar el correo electrónico del agente como parámetro al enlace del formulario de contacto y configurar un campo de correo electrónico para que se complete dinámicamente con ese nombre de parámetro.

¿No desea que el campo rellenado dinámicamente sea visible para el usuario para que no pueda modificar el valor rellenado? Fácil. Simplemente marque Administrativo en la opción Visibilidad en la pestaña avanzada del campo.

Código corto

You can populate a field via the Gravity Forms shortcode by adding the field_values parameter. The field_values parameter accepts multiple dynamic population parameters separated by an ampersand (&).

1

[gravityform id=”1″ field_values=”parameter_name1=value1&parameter_name2=value2″]

In this example, any fields with the dynamic population parameter parameter_name1 would be populated with value1. Fields with the dynamic population parameter parameter2 would be populated by value2.

When is this method useful?

Dynamically populating by shortcode can be useful when you are creating different posts that use the same form but require a custom value depending on which post the form is displayed on.

Imagine you have a few events you’d like to register attendees for. You’ve set up a post for each event and want to use the same registration form for each, changing only the event name in the form based on the event post from which the user is registering.

To do this you would set the dynamic population parameter of the event field to something like event_name and then pass this parameter with the actual event name in the Gravity Forms shortcode like so:

1

[gravityforms id=”1″ field_values=”event_name=My Awesome Event”]

Block

You can populate a field via the Gravity Forms block by using the Field Values text box available in the Advanced tab of a Gravity Forms block. The field values text box accepts multiple dynamic population parameters separated by an ampersand (&).

1

parameter_name1=value1&parameter_name2=value2

In this example, any fields with the dynamic population parameter parameter_name1 would be populated with value1. Fields with the dynamic population parameter parameter2 would be populated by value2. If the Preview setting is also enabled in the current block’s Advanced tab you will see the block update in real time with the dynamically populated values in the editor.

When is this method useful?

This method provides the same benefits described in the Shortcode method above but in a more modern user friendly manner.

Hooks

If you aren’t familiar with PHP and/or hooks, don’t be intimidated by this method for populating your fields. It’s really quite easy. Let’s start with this super basic sample code.

1

2

3

4

add_filter( ‘gform_field_value_your_parameter’ , ‘my_custom_population_function’ );

function my_custom_population_function( $value ) {

     return ‘boom!’ ;

}

This snippet would populate any field with the parameter your_parameter with the result of the function my_custom_population_function. In this example, that function returns the string boom!.

When is this method useful?

When isn’t this method useful? This method allows for the most flexible dynamic population but also requires a bit more knowledge to use. If you’d like to better understand this method check out the documentation on the gform_field_value_parameter_name filter as well as a more Dynamically Populating The Post Author.

Placement

This code can be placed in the functions.php file of the active theme, a custom functions plugin, or custom add-on. See also: Where Do I Put This Code?

Known Limitations

  • Ampersands cannot be used as a field name/parameter or value.
  • The Dynamic Population feature uses PHP to get the value(s) and populate the form field(s). Therefore it can’t be used in cached pages. This is not a Gravity Forms limitation but a consequence of using caching, which prevents PHP code from running.
  • Avoid using these reserved WordPress terms.

Introduction

Using dynamic population in Gravity Forms allows you to dynamically populate a field with a value (or values depending on the field type). This value can be passed via Query Strings, Shortcode and/or Hooks. This walk-through will give you an example of how to use each method of dynamic population to dynamically populate a field on your form!

Getting Started

IMPORTANT: The Dynamic Population feature uses PHP to get the value(s) and populate the form field(s). Therefore it can’t be used in cached pages. This is not a Gravity Forms limitation but a consequence of using caching, which prevents PHP code from running.

There are three steps to configuring dynamic population:

  1. Specify which field should be populated
  2. Configure how the field should be populated
  3. Determine what value the field should be populated with

To get started, let’s talk about specifying which field should be populated. To specify a field for dynamic population, just click the Allow Field To Be Populated Dynamically checkbox on the field’s advanced tab. Doing so will display a text field labeled Parameter Name. The value entered here will act as a reference to this field so Gravity Forms knows which field to populate.

Please note: Avoid using a parameter name from this list of reserved WordPress terms.

Once you’ve entered your parameter name, you’re ready to decide how you want to populate the field.

Query String

You can populate a field via the query string by appending the dynamic population parameter you specified for the field to the end of your form URL along with your custom value.

1

http: //siteurl.com/form-url/?your_parameter=value

Assuming that a Gravity Form is on the page at this URL, any field with the dynamic population parameter name your_parameter would be populated with the value value.

When choosing the parameter name for your fields, be sure to avoid using any of the WordPress reserved terms. Best practice is to use your own prefix to make your parameter names unique. For example, use sa_number instead of number.

In order to pre-select checkbox fields and multiselect fields, provide a comma-separated list of values. Values to be pre-selected in choice based fields are case sensitive.

Some hosts using aggressive caching techniques, like WP Engine, are known to cache not only pages but also query string parameters. So if you’re having trouble getting your fields dynamically populated, please double check your page and query string parameters are not cached.

When is this method useful?

Supongamos que tiene una lista de agentes inmobiliarios que está mostrando en su sitio web. Cada agente tiene un enlace a un formulario de contacto para que los usuarios puedan contactar a cada agente directamente. En lugar de crear un formulario de contacto separado para cada agente, puede agregar el correo electrónico del agente como parámetro al enlace del formulario de contacto y configurar un campo de correo electrónico para que se complete dinámicamente con ese nombre de parámetro.

¿No desea que el campo rellenado dinámicamente sea visible para el usuario para que no pueda modificar el valor rellenado? Fácil. Simplemente marque Administrativo en la opción Visibilidad en la pestaña avanzada del campo.

Código corto

Puede completar un campo a través del código abreviado de Gravity Forms agregando el parámetro field_values . El parámetro field_values ​​acepta múltiples parámetros de población dinámicos separados por un ampersand (&).

1

[gravityform id=”1″ field_values=”parameter_name1=value1&parameter_name2=value2″]

En este ejemplo, cualquier campo con el parámetro de llenado dinámico nombre_parámetro1 se completaría con valor1 . Los campos con el parámetro de población dinámica parámetro2 se completarían con valor2 .

¿Cuándo es útil este método?

Le remplissage dynamique par shortcode peut être utile lorsque vous créez différentes publications qui utilisent le même formulaire mais nécessitent une valeur personnalisée en fonction de la publication sur laquelle le formulaire est affiché.

Imaginez que vous avez des événements pour lesquels vous souhaitez inscrire des participants. Vous avez configuré une publication pour chaque événement et souhaitez utiliser le même formulaire d’inscription pour chacun, en modifiant uniquement le nom de l’événement sur le formulaire en fonction de la publication de l’événement à partir de laquelle l’utilisateur s’inscrit.

To do this, I would set the event field’s dynamic population parameter to something like event_name , then pass that parameter with the actual name of the event in the Gravity Forms shortcode like this:

1

[gravityforms id=”1″ field_values=”event_name=My awesome event”]

to block

You can populate a field through the Gravity Forms block using the Field Values ​​text box available in the Advanced tab of a Gravity Forms block. The field values ​​text box accepts multiple dynamic population parameters separated by an ampersand (&).

1

parameter_name1=value1¶meter_name2=value2

In this example, any field with the dynamic fill parameter parameter_name1 would be filled with the value1. Fields with dynamic population parameter parameter2 would be filled with value2. If the Preview setting is also enabled in the Advanced tab of the current block, you will see the block updating in real time with values ​​dynamically populated in the editor.

When is this method useful?

This method offers the same advantages described in the Shortcode method above, but in a more modern and user-friendly way.

Hands

If you’re unfamiliar with PHP and/or square brackets, don’t be intimidated by this method of filling out your fields. It’s quite easy. Let’s start with this super basic code example.

of them

4

add_filter(‘gform_field_value_your_parameter’, ‘my_custom_population_function’);

function my_custom_population_function( $value ) {

     return ‘boom!’ ;

}

This snippet would populate any field with your_parameter parameter with the result of my_custom_population_function . In this example, this function returns the string boom. .

When is this method useful?

When is this method not useful? This method allows for more flexible population dynamics, but also requires a bit more knowledge to use. For a better understanding of this method, see the gform_field_value_parameter_name filter documentation, as well as more Dynamicly Populating The Post Author.

Placement

This code can be placed in the functions.php file of the active theme, a custom functions plugin or a custom plugin. See also: Where to put this code?

Known limitations

  • Union symbols cannot be used as a field/parameter name or value.
  • The dynamic fill feature uses PHP to get the values ​​and fill in the form fields. Therefore, it cannot be used on cached pages. This is not a limitation of Gravity Forms, but a consequence of using caching, which prevents PHP code from executing.
  • Avoid using these WordPress reserved terms.
