ci框架多图上传

屁话少说，放码过来。

//上传图片
public function do_upload_post()
{
    $config['upload_path'] = 'E:\phpStudy\PHPTutorial\WWW\jisuyun\assets\img\uploads';//上传路径
    $config['allowed_types'] = 'gif|jpg|png';   //文件格式
    $config['max_size'] = 1000;                 //文件大小
    $config['max_width'] = 10240;               //宽
    $config['max_height'] = 7680;               //高
    $config['encrypt_name']=true;               //文件重命名

    $this->load->library('upload', $config);

    foreach ($_FILES as $key => $val) {
        $filename = $_FILES[$key]['name'];
        $tmp = explode('.', $filename);
        $ext = $tmp[count($tmp) - 1];//获取文件后缀
        /*组合$config*/
        $this->upload->initialize($config);// 重点
        $this->upload->do_upload($key);
        $url=$this->upload->data(); //获取图片路径
        var_dump($url['full_path']);
    }

}
