How to Change Checkbox Value from “On” to “Yes” (or Custom Text)

By default, when a user selects a checkbox in a SureForm, the submitted value appears as “on”. If you want to change this value to something more user-friendly like “Yes” or localize it based on the site language, you can easily do this using a filter.

add_filter('srfm_before_prepare_submission_data', function($submission_data) {
    foreach ($submission_data as $key => $value) {
        if (strpos($key, 'srfm-checkbox') !== false || strpos($key, 'srfm-gdpr') !== false) {
            $submission_data[$key] = ($value === "on") ? __( "Yes", "sureforms") : __( "No", "sureforms");
        }
    }
    return $submission_data;
});

How it works:

• This filter runs before form data is saved or sent.
  
• It checks if the submitted field is a checkbox.
  
• If selected, it replaces “on” with “Yes”.
• The __() function ensures it’s translation-ready if you’re building a multilingual site.

Customize for your language or terms:

You can modify the “Yes” to fit your site’s tone or language. For example:

__( "Ja", "sureforms") // German
__( "Oui", "sureforms") // French
__( "Sim", "sureforms") // Portuguese

To ensure the custom text shows correctly in email notifications or webhook data, make sure to place this filter in your theme’s functions.php file or a custom plugin.
