class blog_lib{
var $CI;
var $posts_path;
var $file_ext='.md';
var $_all_posts;
var $_all_tags;
var $_all_pockets;
public function __construct($pathselect)
{
if (!isset($this->CI))
{
$this->CI =& get_instance();
}
$this->posts_path = FCPATH.$pathselect;
}
控制器:
public function index()
{
$this->load->library('blog_lib');
$data['config'] = $this->blog_config;
$this->load->library('twig_lib');
$data['all_tags'] = $this->blog_lib->get_posts_tags();
$data['posts'] = $this->blog_lib->get_posts();
$this->twig_lib->render("index.html",$data);
}
如上我该如何向构造函数传参?
回复内容:
class blog_lib{
var $CI;
var $posts_path;
var $file_ext='.md';
var $_all_posts;
var $_all_tags;
var $_all_pockets;
public function __construct($pathselect)
{
if (!isset($this->CI))
{
$this->CI =& get_instance();
}
$this->posts_path = FCPATH.$pathselect;
}
控制器:
public function index()
{
$this->load->library('blog_lib');
$data['config'] = $this->blog_config;
$this->load->library('twig_lib');
$data['all_tags'] = $this->blog_lib->get_posts_tags();
$data['posts'] = $this->blog_lib->get_posts();
$this->twig_lib->render("index.html",$data);
}

CI是可以往类的构造函数传递参数的,但是构造函数的接受参数时必须是一个数组:
class blog_lib{
...
public function __construct($param){
...
$this->posts_path = FCPATH.$param['pathselect'];
}
...
}
Controller 里面:
$this->load->library('blog_lib',array('pathselect'=> 'xx'));
如果觉得这种方式不好可以用另一个方式,就是在ci的自定义的class做一个虚拟的空类,然后在空类之后再定义一个真实的类,通过config/autoload.php 自动载入这个类,就可以new了,那个时候怎样传递都可以。
application/library/blog.php :
//虚拟类
class blog{}
// 真实类
class blog_lib {
....
}
config/autoload.php
$autoload['libraries'] = array('blog');
Controller 里面:
$oblog = new blog_lib($value);
