Insert_post using contact form 7

Hi there.

I would like to use contact form 7 as a front-end posting tool.
I would like to let user create new posts for my custom post type “products” with a featured image. I was able to create new user with the following code bellow, but how can I amend that code to insert new post to my custom post type “products” with a featured image?
Thanks for looking.
[code]
// register user using contactform7
function create_user_from_registration($cfdata) {
if (!isset($cfdata->posted_data) && class_exists('WPCF7_Submission')) {
// Contact Form 7 version 3.9 removed $cfdata->posted_data and now
// we have to retrieve it from an API
$submission = WPCF7_Submission::get_instance();
if ($submission) {
$formdata = $submission->get_posted_data();
}
} elseif (isset($cfdata->posted_data)) {
// For pre-3.9 versions of Contact Form 7
$formdata = $cfdata->posted_data;
} else {
// We can't retrieve the form data
return $cfdata;
}
// Check this is the user registration form
if ( $cfdata->title() == 'Register User') {
$password = wp_generate_password( 12, false );
$email = $formdata['your-email'];
$name = $formdata['full-name'];
// Construct a username from the user's name
$username = strtolower(str_replace(' ', '', $name));
$name_parts = explode(' ',$name);
if ( !email_exists( $email ) ) {
// Find an unused username
$username_tocheck = $username;
$i = 1;
while ( username_exists( $username_tocheck ) ) {
$username_tocheck = $username . $i++;
}
$username = $username_tocheck;
// Create the user
$userdata = array(
'user_login' => $username,
'user_pass' => $password,
'user_email' => $email,
'nickname' => reset($name_parts),
'display_name' => $name,
'first_name' => reset($name_parts),
'last_name' => end($name_parts),
'role' => 'subscriber');
$user_id = wp_insert_user( $userdata );
if ( !is_wp_error($user_id) ) {
// Email login details to user
$blogname = wp_specialchars_decode(get_option('blogname'), ENT_QUOTES);
$message = "Welcome! Your login details are as follows:" . "\r\n";
$message .= sprintf(__('Username: %s'), $username) . "\r\n";
$message .= sprintf(__('Password: %s'), $password) . "\r\n";
$message .= wp_login_url() . "\r\n";
wp_mail($email, sprintf(__('[%s] Your username and password'), $blogname), $message);
}
}
}
return $cfdata;
}
add_action('wpcf7_before_send_mail', 'create_user_from_registration', 1);
[/code]

so far I manage to get this one

[code]
// Create post object
$my_post = array(
'post_title' => $formdata['form-title-field'],
'post_content' => $formdata['form-content-field'];,
'post_status' => 'publish',
'post_author' => 1, // ID of the author
'post_category' => array(8,39) // your category IDs here
);

// Insert the post into the database
wp_insert_post( $my_post );
[/code]
