        <div class="form-group">

        </div>

        <button type="submit" name="create_new_event" class="btn btn-block">Create Event</button>
    </form>

This is the header.php

global $wpdb;

if(isset($_REQUEST['create_new_event'])) {
    $data = array(
        "name"    => $_REQUEST['name'],
        "phone"   => $_REQUEST['phone'],
        "address" => $_REQUEST['address'],
        "date"    => $_REQUEST['date_of_event'],
        "type"    => $_REQUEST['type'],
        "status"  => 'booked'
    );

    $new  = $wpdb->insert("wp_events", $data);
    wp_redirect(get_permalink());
}

You need exit after redirect.

wp_redirect( $url ); exit;
