在Codeigniter中点击计数器 [英] Hit Counter in Codeigniter

问题描述

我有下面的代码：

（一步一步地）

1. 在 APPPATH中放置 counter.txt 。 'logs / counter.txt'


2. 在中设置 counter_helper.php APPPATH。 'helpers / counter_helper.php';


3. 自动加载 APPPATH中新创建的帮助程序。 'config / autoload.php' file;


4. 在 MY_Controller.php > APPPATH。 'core / MY_Controller.php'


5. 任何控制器都应该扩展 MY_Controller 而不是 CI_Controller ;


6. 在页面上使用< php echo $ this-> count_visitor;？> code>

助手：

 <？php defined（'BASEPATH'）or exit（'No direct script access allowed。'）; 
 
 if（！function_exists（'count_visitor'））{
 function count_visitor（）
 {
 $ filecounter =（APPPATH。'logs / counter.txt'） ; 
 $ kunjungan = file（$ filecounter）; 
 $ kunjungan [0] ++; 
 $ file = fopen（$ filecounter，'w'）; 
 fputs（$ file，$ kunjungan [0]）; 
 fclose（$ file）; 
 return $ kunjungan [0]; 
 
 
 $ / code $ / pre 
 
 
核心： 
 
 
 <？php if（！defined（'BASEPATH'））exit（'No direct script access allowed'）; 
 
 class MY_Controller扩展了CI_Controller 
 {
 public $ count_visitor; 
 public function __construct（）
 {
 parent :: __ construct（）; 
 $ this-> count_visitor = count_visitor（）; 
} 
} 
 / *文件结尾MY_Controller.php * / 
 / *位置：./application/core/MY_Controller.php * / 
  
控制台： 
 
 
 < ;？php if（！defined（'BASEPATH'））exit（'No direct script access allowed'）; 
 class Home扩展MY_Controller {
 public function index（）{
 $ data = array（'isi'=>'home / index_home'）; 
 $ this-> load-> view（'layout / wrapper'，$ data）; 
} 
} 
  
查看：
 <？php echo $ this-> count_visitor;？> 
  
该代码返回如下错误：
  
解决方案
当我加载帮助程序 $ this->时， load-> helper（'counter'）;  
 
 
 
 application> core> MY_Controller.php 
 <？php if（！defined（'BASEPATH'））exit（'No direct script access allowed'）; 
 
 class MY_Controller扩展了CI_Controller 
 {
 public $ count_visitor; 
 
 public function __construct（）
 {
 parent :: __ construct（）; 
 $ this-> load-> helper（'counter'）; 
 $ this-> count_visitor = count_visitor（）; 
} 
} 
  
 
I have the code below:

(Step by step) 

Put counter.txt in APPPATH . 'logs/counter.txt'
Make counter_helper.php set in APPPATH . 'helpers/counter_helper.php';
Autoload newly created helper in APPPATH . 'config/autoload.php' file;
Make MY_Controller.php in APPPATH . 'core/MY_Controller.php'
Any controller should extend MY_Controller instead of CI_Controller;
Echo it on page with: <?php echo $this->count_visitor;?>
The Helper :
<?php defined('BASEPATH') OR exit('No direct script access allowed.');

if ( ! function_exists('count_visitor')) {
    function count_visitor()
    {
        $filecounter=(APPPATH . 'logs/counter.txt');
        $kunjungan=file($filecounter);
        $kunjungan[0]++;
        $file=fopen($filecounter, 'w');
        fputs($file, $kunjungan[0]);
        fclose($file);
        return $kunjungan[0];
    }
}
The Core :
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class MY_Controller extends CI_Controller
 {
  public $count_visitor;
  public function __construct()
   {
     parent::__construct();
      $this->count_visitor = count_visitor();
   }   
 }
/* End of file MY_Controller.php */
/* Location: ./application/core/MY_Controller.php */
The Controller :
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
 class Home extends MY_Controller {
 public function index() {
 $data=array('isi'      =>'home/index_home');
$this->load->view('layout/wrapper',$data); 
 }
}
The View :
<?php echo $this->count_visitor;?>
The code return an error like below :
解决方案
I got it to work fine when I loaded the helper $this->load->helper('counter');

application > core > MY_Controller.php
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class MY_Controller extends CI_Controller
{
    public $count_visitor;

    public function __construct()
    {
        parent::__construct();
        $this->load->helper('counter');
        $this->count_visitor = count_visitor();
    }   
}
