I would have to guess there is a better way, but for now I have found adding the following to the start of the above function works:
global $wpdb;
$user_ID = get_current_user_id();
$company = $wpdb->get_row("SELECT * from wp_usermeta WHERE user_id='".$user_ID."' AND meta_key='company'");
And then adding value=”<?=$company->meta-value ?>” to the input.
If there is a better or more efficient way to complete this, please let me know.
Thank you,
