Contact form 7, save selected option (dropdown menu) to database

Question

I am trying to save to my database, the submissions from my contact form 7 form. I found some functions (don't know the author) to do so. It works, but it won't save the option selected from the drop-down menus to the database. I don't know what I am missing. I tried this:

add_action("wpcf7_submit", "SE_379325_forward_cf7", 10, 2);

function SE_379325_forward_cf7($form, $result) {
 if( !class_exists('WPCF7_Submission') )
  return;
 $submission = WPCF7_Submission::get_instance();
 if ($result["status"] == "mail_sent") { // proceed only if email has been sent 
  $posted_data = $submission->get_posted_data();
  save_posted_data($posted_data);
 }
};


// your insert function:
function save_posted_data($posted_data){
$form_id = $posted_data["_wpcf7"]; // this is the post->ID of the submitted form so if you have more than one you can decide whether or not to save this form fields
if($form_id == 403)
 return;
 global $wpdb;

$wpdb->insert( 
  $wpdb->prefix.'tabletest',
  array(
    'lastname'=>$posted_data['lastName'],
    'name'=>$posted_data['firstName'],
    'email'=>$posted_data['email'],
    'phone'=>$posted_data['tel-3'],
    'subject'=>$posted_data['menu-338'],
    'role'=>$posted_data['menu-761'],
    'message'=>$posted_data['your-message'],
    'thedate'=>$posted_data['date-288']
  ),
  array('%s')
 );
} 

The fields I cannot save are 'subject' and 'role'. They are just empty on my table columns.

This is my form from Contact Form 7

I would appreciate any help.

Two potential problems.

1. The form ID is probably not visible the way you're trying to get it. You can pass that to your function by getting the $contact_form->id in the first submit function.
2. The data from the dropdowns is passed as an array (always) as of a few versions ago in CF7.

I've added sanitization as well, you can alter as needed. CF7 Doesn't by default sanitize data since it's just input in/input out, and not stored anywhere.

add_action( 'wpcf7_submit', 'SE_379325_forward_cf7', 10, 2 );
function SE_379325_forward_cf7( $form, $result ) {
    if ( ! class_exists( 'WPCF7_Submission' ) ) {
        return;
    }
    $submission = WPCF7_Submission::get_instance();
    if ( 'mail_sent' === $result['status'] ) { // proceed only if email has been sent.
        $posted_data = $submission->get_posted_data();
        save_posted_data( $posted_data, $form->id );
    }
}
// your insert function.
function save_posted_data( $posted_data, $form_id ) {
    if ( 403 !== $form_id ) {
        global $wpdb;
        $wpdb->insert(
            $wpdb->prefix . 'tabletest',
            array(
                'lastname' => sanitize_text_field( wp_unslash( $posted_data['lastName'] ) ),
                'name'     => sanitize_text_field( wp_unslash( $posted_data['firstName'] ) ),
                'email'    => sanitize_text_field( wp_unslash( $posted_data['email'] ) ),
                'phone'    => sanitize_email( wp_unslash( $posted_data['tel-3'] ) ),
                'subject'  => sanitize_text_field( wp_unslash( $posted_data['menu-338'][0] ) ),
                'role'     => sanitize_text_field( wp_unslash( $posted_data['menu-761'][0] ) ),
                'message'  => sanitize_textarea_field( wp_unslash( $posted_data['your-message'] ) ),
                'thedate'  => sanitize_text_field( wp_unslash( $posted_data['date-288'] ) ),
            ),
            array( '%s' )
        );
    }
}
