前端代码
<html>
<form action="ci/CodeIgniter_2.2.0/index.php/upload/up" method="post" enctype="multipart/form-data">
<input type="file" name="upfile" />
<input type="submit" name="sub" value="提交" />
</form>
</html>
控制器：
定义一个数组，设置一些与上传相关的参数
$config['upload_path'] = './uploads/'; //设置允许上传的类型 $config['allowed_types'] = 'gif|jpg|png'; $config['max_size'] = '100'; //如果是图片还可以设置最大高度和宽度 $config['max_height'] = 768; $config['max_width'] = 1024;
调用CI的上传通用类，并执行上传
//upload为调用的类名，全小写
$this->load->library('upload',$config);
//如果上传框的name写的是userfile，那就不用传参数了，如果不是，把name的值传进去
$this->upload->do_upload('上传框的name');
接收出错信息或成功信息
//出错信息
$error = array('error' => $this->upload->display_error());
//成功信息
$data = array('upload_data' => $this->upload->data());
<?php
if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Upload extends CI_Controller {
//显示带表单的视图
public function index(){
$this->load->view('up');
}
//显示上传信息
public function up(){
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = "2000";
$this->load->library('upload',$config);
//打印成功或错误的信息
if($this->upload->do_upload('upfile'))
{
$data = array("upload_data" => $this->upload->data());
var_dump($data);
}
else
{
$error = array("error" => $this->upload->display_errors());
var_dump($error);
}
}
}
