ci框架——辅助函数

辅助函数：application/helper下面。命名要求为***_helper.php;这样在调用的时候
直接$this->load->helper('***');
若想给自定义的辅助函数传参数：$config=函数名（）；

以辅助函数分页为例子：
page_helper.php
<?php
function page($link_url,$total_nums,$page_num){
$config['base_url'] =$link_url;
$config['total_rows'] = $total_nums;
$config['per_page'] = $page_num;
$config['full_tag_open'] = '<p>';
$config['full_tag_close'] = '</p>';
$config['first_link'] = '首页';
$config['first_tag_open'] = '<li>';
$config['first_tag_close'] = '</li>';
$config['last_link'] = '末页';
$config['last_tag_open'] = '<li>';
$config['last_tag_close'] = '</li>';
$config['next_link'] = '下一页';
$config['next_tag_open'] = '<li>';
$config['next_tag_close'] = '</li>';
$config['prev_link'] = '上一页';
$config['prev_tag_open'] = '<li>';
$config['prev_tag_close'] = '</li>';
$config['cur_tag_open'] = '<li class="current">';
$config['cur_tag_close'] = '</li>';
$config['num_tag_open'] = '<li>';
$config['num_tag_close'] = '</li>';
$config['uri_segment'] = 4;////将分页数据传输位置改为4
return $config;

}

在控制里面调用：
$page_num = '2';
//每页显示的数目
$this->load->model('Page_model');
$data= $this->Page_model->page('tx_news',$page_num,$this->uri->segment(4),$id);
//加载分页的控制器；
$total_nums=count($news);
$data['query']=$data[0];
$this->load->library('pagination');
$config=page($this->config->item('base_url')."/index.php/News/index/{$id}",$total_nums,$page_num);
$this->pagination->initialize($config);
