图片上传并生成缩略图【由于thinkphp没有自带生成缩略图需要自己写上传的类】

将下面两个文件放到Library/Think/下面

1: UploadFile.class.php

2: UploadImage.class.php

$upload=newUploadFile();//实例化上传类

$upload->maxSize=3145728;//设置附件上传大小

$upload->allowExts=array('jpg','gif','png','jpeg');//设置附件上传类型

$upload->allowTypes=array("image/jpg","image/gif","image/png","image/jpeg","image/jgpeg");//设置附件上传类型

$upload->saveName= time() . mt_rand();//文件的名称

$upload->savePath='Public/SameGo/images/li/blog/share/';//图片的保存目录

$upload->autoSub=false;

$upload->thumb=true;//设置需要生成缩略图，仅对图像文件有效

$upload->thumbPrefix='s_';//设置需要生成缩略图的文件后缀，支持多张 - "s_,m_"

//        $upload->thumbPath = "Public/SameGo/images/li/blog/share/thumb/";//不生效

$upload->thumbMaxWidth='370';//设置缩略图最大宽度

$upload->thumbMaxHeight='250';//设置缩略图最大高度

$upload->thumbRemoveOrigin=false;//删除原图

$upload->saveRule=uniqid;//设置上传文件规则

//上传文件

if($upload->upload()) {//上传错误提示错误信息

$info=$upload->getUploadFileInfo();

 echo $info[0]["savename"];//图片的名称

$data["image"] ='/helper/Public/SameGo/images/li/blog/share/'.$info[0]["savename"];//图片的路径

$data["thumb"] ='/helper/Public/SameGo/images/li/blog/share/'."s_".$info[0]["savename"];//缩略图的路径

}else{

echo"no";

}
