我想使用Codeigniter隱藏該ID並在網址中顯示唯一ID？

Question

<a href="<?php echo base_url();?>index.php/registration/invoice/<?php echo ($rows['id']);?>">

function invoice()
{
    $paymentid=$this->uri->segment('3');$record=$this->Registration_model->get_data($paymentid);
}

Answer 1

使用base64_encode創建加密的ID

<a href="<?php echo base_url();?>index.php/registration/invoice/<?php echo base64_encode($rows['id']);?>">

function invoice()
{
    $paymentid=base64_decode($this->uri->segment('3'));
    $record=$this->Registration_model->get_data($paymentid);
}

Answer 2

使用base64_encode可以輕松解密。

請將這兩個函數添加到您的助手中以對ID進行編碼以解碼：

function encode_url($string)
{

        $CI =& get_instance();
        $CI->load->library('encryption');
        $ret = $CI->encryption->encrypt($string);
        return str_replace(array('+', '/', '='), array('-', '_', '~'),$ret);

}

function decode_url($string)
{
        $CI =& get_instance();
        $CI->load->library('encryption');
        $ret = str_replace(array('-', '_', '~'),array('+', '/', '='),$string);
        return $CI->encryption->decrypt($ret);
}

所以你會編碼

<a href="<?php echo base_url();?>index.php/registration/invoice/<?php echo encode_url($rows['id']);?>">

function invoice()
{
    $paymentid = decode_url($this->uri->segment('3'));

    $record = $this->Registration_model->get_data($paymentid);
}
