Uncaught PDOException: SQLSTATE[HY093]: Invalid parameter number: parameter was not defined Hatası

Merhabalar. Yaklaşık 6 saattir çözmeye çalıştığım başlıktaki hatayı sizlere de danışmak istedim. Şimdiden çok teşekkürler.
Datanın alındığı yer

$('#registerForm').on('submit', function (e){
    e.preventDefault();
    var registerData = $(this).serialize();
    $.ajax({
        method: 'POST',
        url: '/register',
        data: registerData
    }).done(function (response){
        console.log(response);
    });
});

Datanın alıp iletildiği yer

public function Register(){
        unset($_POST['WHERE']);
        $data = $_POST;
        $this->save('users', $data);
    }

İşlemin yapıldığı yer

namespace app\root;

class Database
{
    protected \PDO $db;
    public function __construct()
    {
        $this->db = new \PDO('mysql:host=localhost;dbname=farmroad;charset=utf8', 'root', 'xxx');
        $this->db->setAttribute(\PDO::ATTR_ERRMODE, \PDO::ERRMODE_EXCEPTION);
    }
    public function save($table, $data)
    {
        $columns = $this->findColumns($data);
        $params = $this->findParams($data);
        $statement = $this->db->prepare("INSERT INTO $table($columns)VALUES($params)");

//        echo '<pre>';
//            var_dump($statement, $columns, $params);
//        echo '</pre>';
//        exit;
//        $bindPrepared = explode(',', $columns);
        foreach ($data as $final => $value) {
            $statement->bindValue(":$final", $value);
            var_dump($statement, $final, $value);
        }
        $statement->execute();
    }

    {
        $enc = '';
        foreach ($data as $final => $values) {
            $final = $final.',';
            $enc .= $final;

resimler açılmıyor

Düzeltiyorum hocam hemen codepen olarak eklemiştim. Şuan düzelmiş olmalı.

Hocam burdan çok birşey anlaşılmıyor. Fakat https://stackoverflow.com/questions/...rameter-number burası faydalı olabilir sql yapınızı burdaki gibi düzeltin

Anladığım kadarıyla linkteki arkadaş iki kez aynı ismi iki kez kullandığı için böyle olmuş. Lakin bende tekrarlanan bir şey yok hocam. Bakıyorum bakıyorum anlayamıyorum. Başka bir türlü yapılabilir belki ama şuan o da aklıma gelmiyor. Büyük bir çıkmazın içindeyim
