Submit checkbox form in WordPress

I have a PHP checkbox form to send to WordPress after a submit button

But I don't know how to go about it, do you have a clue to enlighten me?

Thanks you.

Form

<div class="container mt64">
<?php
    $active_plugins = apply_filters( 'active_plugins', get_option( 'active_plugins' ) );
    if (in_array( 'interparking_marketing_questions/interparking_marketing_questions.php', $active_plugins)) :
        ?>
