上传类
1.上传类的配置项
$config['upload_path'] = '文件上传的位置'; $config['allowed_types'] = 'gif|jpg|png'; $config['max_size'] = '100';//单位为kb ,php.ini 限制为 2M $config['encrypt_name'] = 'true';//文件名随机 $config['max_width'] = '1024';//针对图片类型宽度限制 $config['max_height'] = '768';//针对图片类型高度限制
2.加载上传类
$this->load->library('upload',$config);
3.判断是否上传成功
$this->upload->do_upload('fileName');//文件域中表单 name
4.获取上传后的数组
$this->upload->data();
5.获取上传失败的信息
$this->upload->display_errors();
6.上传类使用技巧
当多文件上传时遍历
$this->upload->initialize($config);//初始化 $this->upload->do_upload('fileName');//判断成功保存full_path
图片类
1.配置项
$config['source_image'] = $data['full_path'] ; //图片类和上传类关联
2.加载类文件
$this->load->library('image_lib');
3.初始化
$this->image_lib->initialize($config);
4.生成图片
$this->image_lib->resize();
