ThinkPHP3.1.3图片上传实例
1、将上传和缩略图处理扩展放在TP核心中，直接覆盖压缩包中的ThinkPHP即可
2、下载jquery.uploadify插件 即文件包中的Public/uploadimg/js/uploadify-v3.1/
3、在上传页面模板引入js和css<link>
<br>
<script></script>当然也必须引入：jquery库文件
4、在上传页面模板<script><br />
$(function() {<br />
$('#file_upload').uploadify({<br />
'swf' : '__PUBLIC__/uploadimg/js/uploadify-v3.1/uploadify.swf',<br />
'uploader' : '{:U("Student/uploadify")}',<br />
'buttonText' : '上传头像',<br />
'onUploadSuccess' : function(file, data, response) {<br />
$('#image').attr('src','/Uploads/images/130_'+data);<br />
$('#pic').val(data);<br />
},<br />
});<br />
});<br />
</script>5、上传表单：<div>
<br>
<label>照片：</label><br>
<img alt="ThinkPHP图片上传实例" ><br>
<input><br>
<input><br>
</div>6、上传函数：public function uploadify(){<br>
if (!empty($_FILES)) {<br>
import("ORG.NET.UploadFile");<br>
$upload = new UploadFile();<br>
$upload->maxSize = 2048000;<br>
$upload->allowExts = array('jpg','jpeg','gif','png');<br>
$upload->savePath = "./Uploads/images/";<br>
$upload->thumb = true; //设置缩略图<br>
$upload->imageClassPath = "ORG.Util.Image";<br>
$upload->thumbPrefix = "130_,75_"; //生成多张缩略图<br>
$upload->thumbMaxWidth = "130,75";<br>
$upload->thumbMaxHeight = "130,75";<br>
$upload->saveRule = uniqid; //上传规则<br>
$upload->thumbRemoveOrigin = true; //删除原图<br>
if(!$upload->upload()){<br>
$this->error($upload->getErrorMsg());//获取失败信息<br>
} else {<br>
$info = $upload->getUploadFileInfo();//获取成功信息<br>
}<br>
echo $info[0]['savename']; //返回文件名给JS作回调用<br>
}<br>
}
