在codeigniter中的控制器中调用帮助函数 [英] call a helper function in controller in codeigniter
本文介绍了在codeigniter中的控制器中调用帮助函数的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我为访问量创建了一个帮助器,它包含一个将一些数据插入数据库的功能:
I created a helper for visit hits and it contains a function which inserts some data in to the database:
hits_counter_helper.php :
function count_hits($options = array())
{
//Determine whether the user agent browsing your site is a web browser, a mobile device, or a robot.
if ($this->agent->is_browser())
{
$agent = $this->agent->browser() . ' ' . $this->agent->version() . ' - ' . $this->agent->platform();
}
elseif ($this->agent->is_robot())
{
$agent = $this->agent->robot();
}
elseif ($this->agent->is_mobile())
{
$agent = $this->agent->mobile();
}
else
{
$agent = 'Unidentified User Agent';
}
//Detect if the user is referred from another page
if ($this->agent->is_referral())
{
$referrer = $this->agent->referrer();
}
// correcting date time difference by adding 563 to it.
$date = date('Y-m-j H:i:s', strtotime(date('Y-m-j H:i:s')) + 563);
$data = array (
'page_Address' => current_url(),
'user_IP' => $this->input->ip_address(),
'user_Agent' => $agent,
'user_Referrer' => $referrer,
'hit_Date' => $date
);
$this->db->insert('counter', $data);
}
自动加载帮助程序并在我的函数中调用此函数控制器为:
once I auto loaded the helper and called this function in my controller as:
My_controller.php :
public function index() {
count_hits();
//index code here
}
问题是我越来越我认为空白页和其他代码无法运行。我在做什么错?!
The problem is that I am getting a blank page and other codes does not run I think. What am I doing wrong?!
推荐答案
在辅助函数的开头添加以下代码:
Add the following code to the beginning of your helper function:
//get main CodeIgniter object
$CI =& get_instance();
将所有 $ this
替换为 $ CI
。
然后在控制器中的任意位置加载辅助函数,如下所示:
and then load the helper function wherever you want in your controller like this:
count_hits();
