Fluent Forms hooks & filters cheatsheet

Fluent Forms has lots and lots of hooks and filters. I have found the most useful and common hooks and filters and put them into a big list with examples and use cases for people to quickly find and reference.

Quick Links

fluentform_insert_response_data

This hook is used to modify the data from your form before it is saved to the database.

Some use cases could be:

• Pulling data dynamically from elsewhere in your website like custom fields
• Adding or subtracting information entered
• Calculating date of birth

Essentially anything that needs to be done server side, and you don’t want to be cached.

        <?php

add_filter('fluentform_insert_response_data', 'tct_my_function', 10, 3);

function tct_my_function($formData, $formId, $inputConfigs)
{
   if($formId != 1) { // Replace with your Form ID
      return $formData;
   }

    $input_email = $formData['email']; // change 'email' with your input field name

    return $formData;
}

fluentform_rendering_field_data_{input_key}

This hook is used to modify the input data. This includes the actual input data and input settings.

Some use cases could be:

• Dynamically populating a select dropdown with external data
• Load ACF field data from the specific post
• Generate a random code with a PHP snippet

You need to replace {input_key} with the field type that you want to use.

Field type examples:

• input_text
• input_number
• select
• email
• address

        <?php 

add_filter('fluentform_rendering_field_data_input_text', 'tct_my_function', 10, 2);

function tct_my_function($data, $form)
{
    if($form->id != 1) {
        return;
    }

    // Check if our field is equal to my_text_field
    if (\FluentForm\Framework\Helpers\ArrayHelper::get($data, 'attributes.name') != 'my_text_field') {
        return $data;
    }



    return $data;
}

Smartcodes

Smartcodes are used for dynamic data in the inputs default value

Smartcodes are made up of 2 hooks.

• fluentform_editor_shortcodes – For form editor list
• fluentform_all_editor_shortcodes – For Email/Confirmation Settings list
• fluentform_shortcode_parser_callback_{smartcode_name} – Transforming your data

Some use cases could be:

• Load ACF field data from the specific post
• Generate a random code with a PHP snippet
• Email confirmation data

You need to replace {smartcode_name} with the name of your smartcode.

        add_filter('fluentform_editor_shortcodes', function ($smartCodes) {
    $smartCodes[0]['shortcodes']['{my_own_smartcode}'] = 'My Own smartcode';
    return $smartCodes;
});

add_filter('fluentform_editor_shortcode_callback_my_own_smartcode', function ($value, $form) {
    $dynamicValue = $form->title; // Returns current form title. You can fetch any data and return it here.
    return $dynamicValue;
}, 10, 2);
