Reply To: Select Field: Change / Add own data sources

You can do this via hook and erase the already existing contents and prefill it with our own.
Basically you can then prefill everything what you want 🙂

Example:

namespace ct_example;

class WsForm
{
    public static function Prefill($form)
    {
        $fieldId = 123;
        $matchingField = &wsf_form_get_field($form, $fieldId);
        wsf_field_rows_clear($matchingField);

        $prefillData = Helper::GetMyPrefillData(); // returns key/value pairs
        if ($prefillData) {
            foreach ($prefillData as $prefillEntryKey => $prefillEntryValue) {
                $row = (object)[
                    'default' => false, // you can create logic to preselect entries
                    'data' => [$prefillEntryValue, $prefillEntryKey] // you need to add the key/value fields to your dropdown!
                ];
                wsf_field_row_add($matchingField, $row);
            }
        }

        return $form;
    }
}
add_filter('wsf_pre_render', ['\\' . __NAMESPACE__ . '\\WsForm', 'Prefill']);
