The section that you suggested doesn't exist; this is the closest that I could find:
while ($data = $QproductDescriptions->fetch_assoc()) {
foreach ($clicshopping_languages as $languages) {
echo $data['products_id'] . ' - ' . $data['products_name'] . '<br />';
$sql_data_array = [
'products_id' => (int)$data['products_id'],
'language_id' => (int)$languages['languages_id'],
'products_name' => $data['products_name'],
'products_description' => $data['products_description'],
'products_url' => $data['products_url'],
'products_viewed ' => (int)$data['products_viewed'],
];
// $this->db->save('products_description', $sql_data_array);
}
}
