codeigniter controlers中加载config失败

monlone · 发表于 2011-11-16 09:40:54

我的配置文件config.php如下：
$config['base_url'] = 'http://localhost:8080';（我加的）
$config['index_page'] = 'index.php';
.
.(中间没有改动动省略。。。。)
.
$config['css'] = "mystyles.css";（我加的）
-----------------------------------------------------
我的routers.php文件如下：
$route['default_controller'] = "Start";
$route['404_override'] = '';
-----------------------------------------------------
我的start.php文件如下：
<?php
class Start extends CI_Controller {
var $base;
var $css;
function Start()
{
      parent::CI_Controller();
      $this->config->load('config');
      $this->base = $this->config->item('base_url','config');
      $this->css = $this->config->item('css');
}
function index($name)
{
      $data['css'] = $this->css;
      $data['base'] = $this->base;
      $data['mytitle'] = 'Welcome to this site';
      $data['mytext'] = "Hello, $name, now we're getting dynamic!";
      #$this->load->view('testview', $data);
}
}
？>
---------------------------------------------------------------------------------
我的testview.php文件如下：
<html>
<head>
  <!DOCTYPE html PUBLIC '-//W3C//DTD XHTML 1.0 Strict//EN'http:\/\/www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd'>
  <html xmlns="http:\/\/www.w3.org/1999/xhtml">
  <title>Web test Site</title>
  <base href="<?php echo "$base"; ?>">
  <link rel="stylesheet" type="text/css" href="<?php echo "$base/$css";?>">
</head>
<body>
  <h1><?php echo $mytitle; ?> </h1>
  <p class="test"> <?php echo $mytext; ?> </p>
</body>
</html>
-----------------------------------------------------
为什么我在运行的时候会如下报错误：
Fatal error:  Call to undefined method CI_Controller::CI_Controller() in D:\phpnow\htdocs\CodeIgniter\application\controllers\start.php on line 7
-----------------------------------------
要是我不要 parent::CI_Controller();这句代码,即我的start.php文件如下：
<?php
class Start extends CI_Controller {
var $base;
var $css;
function Start()
{
      #parent::CI_Controller();
      $this->config->load('config');
      $this->base = $this->config->item('base_url','config');
      $this->css = $this->config->item('css');
}
function index($name)
{
      $data['css'] = $this->css;
      $data['base'] = $this->base;
      $data['mytitle'] = 'Welcome to this site';
      $data['mytext'] = "Hello, $name, now we're getting dynamic!";
      #$this->load->view('testview', $data);
}
}
?>
则报如下错误：
A PHP Error was encounteredSeverity: Notice
Message:  Undefined property: Start:

config
Filename: controllers/start.php
Line Number: 8

Fatal error: Call to a member function load() on a non-object in D:\phpnow\htdocs\CodeIgniter\application\controllers\start.php on line 8

我该怎么加载config.php这个里面的配置啊？比如我想要我自己定义的$config['css'] = "mystyles.css";（我加的）这个变量。我的start.php该怎么写啊？是不是我对codeigniter理解有错误？是语法不对呢？还是我的配置有问题？
（要是直接输出'HELLOWORLD'这样简单的东西却不报错了。。。。）
请高手帮忙啊。小弟在此谢过了！

config.php会自动加载的，你只要$this->config->item();来取里面的值就是了

$this->css = $this->config->item('css');
echo $config['css'];
}
function index()
{
$data['css'] = $this->css;
$data['base'] = $this->base;
$data['mytitle'] = 'Welcome to this site';
$data['mytext'] = "Hello, now we're getting dynamic!";
#$this->load->view('testview', $data);
}
}
?>
我是这样子调用的啊。可是还是给我报错：A PHP Error was encountered

Severity: Notice

Message: Undefined property: Start:

config

Filename: controllers/start.php

Line Number: 9

Fatal error: Call to a member function item() on a non-object in D:\phpnow\htdocs\CodeIgniter\application\controllers\start.php on line 9

提示我出现以上错误。。。。
