Codeigniter网址重定向

Question

我曾经在url前加密我的数据ID。 mywebsite.com/product/detail/encryptedid，然后如果我转到该链接，它将显示该特定产品的所有信息。 但是当我尝试更改诸如某些随机字符串ex之类的cryptonid时。 mywebsite.com/product/detail/asd123它将显示错误“试图获取非对象的属性”我很好奇如何防止这种错误，例如如果他们将加密的url更改为一些随机字符串，可以重定向到原始的mywebsite.com/product/detail/encryptedid，该页面仍会显示该特定产品的信息，或转到404页。

要获得清晰的示例，请看下面的图片。

public function details($id){

    $decrypt = secret_url('decrypt',$id);

    $prod_row = $this->ProductModel->getonerow($decrypt);
    $data['product_detail'] = $prod_row;

    $data['title'] = "Ayos Computer | Product Details";
    $data['category'] = $this->ProductModel->get_category();
    $data['products'] = $this->ProductModel->get_product();

    $this->load->view('include/header',$data);
    $this->load->view('include/nav');
    $this->load->view('products/ProductDetail', $data);
    $this->load->view('include/footer');
}

视图

 <a href="<?= base_url() .'products/details/' . secret_url('encrypt',$featured_row->product_id) ?>"></a>

先感谢您。

就像没有产品一样：

public function details($id)
{

    $decrypt = secret_url('decrypt',$id);

    $prod_row = $this->ProductModel->getonerow($decrypt);

    if (null !== $prod_row) {
        $data['product_detail'] = $prod_row;

        $data['title'] = "Ayos Computer | Product Details";
        $data['category'] = $this->ProductModel->get_category();
        $data['products'] = $this->ProductModel->get_product();

        $this->load->view('include/header',$data);
        $this->load->view('include/nav');
        $this->load->view('products/ProductDetail', $data);
        $this->load->view('include/footer');
    } else {
        // CI default 404 view if left blank value
        show_404($custom_page = '');
    }
}
