I think you would just change this:
if (is_already_submitted($formName, $fieldName, $_POST[$name])) {
to this:
if (! is_already_submitted($formName, $fieldName, $_POST[$name])) {

[cfdb-table] gives a plain, unstyled HTML table. You can add your own CSS to set the style of your table. Some styles you are seeing (like the font size) are probably inherited from your theme.

I’m having difficulty understanding the English here. I will answer to the best of my understanding.

1. No, the plugin will not update an existing entry. It will always create a new entry.

2. There is a way to make a shortcode filter on the user. See http://cfdbplugin.com/?page_id=116

3. There is an editing capability that you can purchase https://cfdbplugin.com/?page_id=459

4. I don’t know about the mobile phone issue. Is this output form [cfdb-table] or [cfdb-datatable]?

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');

I would need a complete example including form definition and hook code to reproduce the problem.

This appears to be a system configuration issue, not a plugin issue.

Your PHP process cannot write to the Windows temporary directory. That where uploaded files go while PHP is processing them (and not just by this plugin). So there is something wrong in your configuration on Windows that doesn’t allow the process (or logged in user) to write there. Or the PHP configuration on that computer that tells PHP which is the temporary directory is wrong. It seems very strange that there are spaces in the file file in your error message. Maybe that is the issue.

Evidently WPFORMS would need custom code to process its form submissions.
