Save data depending of checkboxes in different databases

Based on Manipulating Form Data Before it is Saved,

Assuming the values submitted in your checkboxes are the form names, I think this would work:

require_once(ABSPATH . 'wp-content/plugins/contact-form-7-to-database-extension/CF7DBPlugin.php');

function save_to_multiple_forms($formData) {
    $formName = 'your-form'; // change this to your form's name
    $fieldName = 'form-names-field'; // change this to your form's name
    if ($formData && $formName == $formData->title) {
        if (isset($formData->posted_data[$fieldName]) && is_array($formData->posted_data[$fieldName])) {
            $plugin = new CF7DBPlugin();
            $num_selections = count($formData->posted_data[$fieldName]);
            for ($idx = 0; $idx < $num_selections; ++$idx) {
                $formData->title = $formData->posted_data[$fieldName];
                if ($idx < ($num_selections - 1)) {
                    $plugin->saveFormData($formData);
                }
            }
        }
    }
    return $formData;
}

add_filter('cfdb_form_data', 'save_to_multiple_forms');

Thank you Michael!

I have tried with this code but I think I made some mistake.

Contactform: Nordcup_2017
[checkbox* checkbox-839 “Verein 1” “Verein 2” “Verein 3” “Verein 4” “Verein 5” “Verein 6” “Verein 7”]

` $formName = ‘Nordcup_2017’; // change this to your form’s name
$fieldName = ‘checkbox-839’; // change this to your form’s name

Now when i trie this it creates always a DB which has no name and is empty.

I think it’s a similar mistake from me.

MANY THANKS!!!!

My code suggestion might not be quite right. You may have to play around with it.
