ThinkPHP使用心得分享-上传类UploadFile的使用_PHP
ThinkPHP
上传类的使用很简单,如果是第一次使用上传功能的朋友需要注意的是html提交表单中的表单属性要加上 enctype属性,如:
复制代码 代码如下:
ThinkPHP的UploadFile类在文件../ThinkPHP/Extend/Library/ORG/Net/UploadFile.class.php中:
复制代码 代码如下:
//引入UploadFile类
import('ORG.Net.UploadFile');
//实例化UploadFile类
$upload = new UploadFile();
//设置文件大小
$upload -> maxSize = 3292200;
//设置文件保存规则唯一
$upload->saveRule = 'uniqid';
//设置上传文件的格式
$upload -> allowExts = array('jpg','png','jpeg');
//保存路径
$upload->savePath ='./Public/Uploads/';
//设置需要生成缩略图,仅对图像文件有效
$upload->thumb = true;
//设置需要生成缩略图的文件前缀
$upload->thumbPrefix = 'm_'; //生产缩略图也可以根据需要生成1张或多张,2张:'m_,s_'
//设置缩略图最大宽度
$upload->thumbMaxWidth = '150';//2张的不同设置:'150,200'
//设置缩略图最大高度
$upload->thumbMaxHeight = '200';
//删除原图
$upload->thumbRemoveOrigin = true;
//上传失败返回错误信息
if(!$upload->upload()){
$this->error($upload->getErrorMsg());
}else{
$this->success('上传成功');
//获取上传文件的信息
$inf= $upload->getUploadFileInfo();
}
经过设置后就能轻松地上传文件,同时,$upload的getUploadFileInfo可以获取上传的文件的信息。
