分页内容
文件上传
分页使用
public function test()
{
$config['base_url'] = site_url('user/test');
$config['total_rows'] = '200';
$config['per_page'] = '20';
// 转成整数,获取内容
$offset = intval($this->uri->segment(3));
// 在这里拼接sql语句，这里返回的是偏移量
echo $offset;
// 自定义内容
$config['first_link'] = '首页';
$config['last_link'] = '尾页';
$config['next_link'] = '下一页';
$config['prev_link'] = '上一页';
$this->pagination->initialize($config);
echo $this->pagination->create_links();
}
注意：__contruct方法写完之后，要添加parent::__contruct否则会找不到
文件上传

$this->load->library('upload', $config);
$bool = $this->upload->do_upload('pic');
echo $bool;
// $this->upload->initialize($config);
var_dump($this->upload->data());
$data = $this->upload->data();
echo $data['file_name'];
