Credits and thanks to Contact Form 7 author.

The author of Contact Form 7 is Takayuki Miyoshi, a web developer from Tokyo, Japan. Takayuki has been developing contact forms with WordPress since 2006, when he first released contact-form-7, originally a fork of the popular contact form plugin, which WordPress then adopted as its official contact form plugin. Takayuki’s contact forms have been widely used ever since and are now the most popular contact form plugins for WordPress.

Let’s start with the simplest and probably the most common modification, that is:

How to do something additional (save to a file, save in a database, create an entry, etc.) with the submitted form?

Thanks to the plugin author’s provision, adding such integration is relatively easy. Let’s look at the code below, which implements probably the simplest form of such integration, and at the same time, is an excellent start to building your own more complex versions:

function prefiks_process_submitted_form_data( $contact_form ) {
    $submission = WPCF7_Submission::get_instance();
    if ( $submission ) {

        // Get the data submitted in the form
        $submitted_name = $submission->get_posted_data('your-name');
        $submitted_email = $submission->get_posted_data('your-email');
        $submitted_subject = $submission->get_posted_data('your-subject');
        $submitted_message = $submission->get_posted_data('your-message');
        // ...

        // Do something with the data (e.g. save it to a file)
        file_put_contents('cf7-log.txt', 'Data: ' . date('c') . "\n", FILE_APPEND);
        file_put_contents('cf7-log.txt', "Autor: {$submitted_name} <{$submitted_email}>\n", FILE_APPEND);
        file_put_contents('cf7-log.txt', 'Temat: ' . $submitted_subject . "\n", FILE_APPEND);
        file_put_contents('cf7-log.txt', "Wiadomość:\n" . $submitted_message, FILE_APPEND);
        file_put_contents('cf7-log.txt', "\n--------------------\n", FILE_APPEND);
    }
}
add_action( 'wpcf7_before_send_mail', 'prefiks_process_submitted_form_data' );

Additional variants and questions

I have multiple forms. How can I check which one has been sent?

The object of the submitted form is passed as the action parameter. We can check its ID (entry ID with form description), name and title.

$form_id = $contact_form->id();
$form_name = $contact_form->name();
$form_title = $contact_form->title();

My form does not have to send an email after being processed. Can I block it somehow?

Yes. The author of the plugin also foresaw this possibility.in your function attached to the action skip_mail to true as follows:

$ contact_form-> skip_mail = true;

How to get into all the data sent?

Just use $ data = $ submission-> get_posted_data ();. This way, in the $ data we will have an array containing all the data submitted in the form.

How do I process files sent in the form?

For example:

$ uploaded_files = $ submission-> uploaded_files ();
foreach ((array) $ uploaded_files as $ name => $ path ) {
    // do something with the file sent from the field named $ name,
    // it is on the server in the place specified by $ path
