[英]Codeigniter url redirect
I used to encrypt the id of my data in my url ex. 我曾经在url前加密我的数据ID。 mywebsite.com/product/detail/encryptedid then if i would go to that link it will show all the info of that specific product.
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。 but when i tried to change the encryptedid such as some random string ex.
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 it will show the error "Trying to get property of non-object" I'm curious how to prevent it in such a way like if they will change the encrypted url to some random strings it can redirect to the original mywebsite.com/product/detail/encryptedid which will show still the info of that specific product or go to 404 page.
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。
for clear example look at the image below. 要获得清晰的示例,请看下面的图片。
Image with encryption 加密图像
Image with inputted random string 输入了随机字符串的图像

My Controller 我的控制器
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);
$this->load->view('include/footer');
}
VIEW 视图
<a href="<?= base_url() .'products/details/' . secret_url('encrypt',$featured_row->product_id) ?>"></a>
thank you in advance. 先感谢您。
As same way as if there was no product: 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 = '');
}
}
