效果圖:
密保卡入庫
復制代碼 代碼如下:
$this->load->model('admin/m_mibao');
$data = array();
//生成隨機橫坐標
$rand_str = $this->_rand_str(10);
$arr = array();
for($k=0;$k<strlen($rand_str);$k++)
{
for ($i = 1;$i < 9;$i++)
{
$rand = $this->_rand_num(3);
//賦給所有code的容器
$arr[$rand_str{$k} . $i] = $rand;
}
}
$data['code'] = serialize($arr); //序列化後將信息入庫
$data['letter'] = $rand_str;
//避免重復序列號
while (TRUE)
{
$data['card_num'] = $this->_rand_num(20);
//判斷序列號是否重復存在
if($this->m_mibao->has_card_num($data['card_num']) == 0)
{
break;
}
}
$data['add_time'] = TIME;
$data['user_id'] = $uid;
echo $this->mibao->insert($data);
密保卡圖片生成
復制代碼 代碼如下:

if(emptyempty($info))

}

密保卡驗證
復制代碼 代碼如下:
public function test1($uid)
{
$this->load->model('admin/m_users');
$user = $this->m_users->sel($uid);
//post提交過來驗證
if($this->is_post())
{
$codes = $this->m_mibao->get_codes_by_uid($uid);
$codes = unserialize($codes);
$is_true = true;
foreach($_SESSION['mibao']['keys'] as $key)
{
if($codes[$key] != $_POST['values'][$key])
{
$is_true = false;
}
}
if($is_true)
{
die('正確');
}
else
{
die('錯誤');
}
}
else
{
//渲染視圖
$info = $this->m_mibao->get_by_uid($uid);
$data = array();
$data['keys'] = $this->m_mibao->get_rand_keys($info['letter']);
$_SESSION['mibao']['keys'] = $data['keys'];
$data['uid'] = $uid;
$this->load->view('test1',$data);
