thinkphp3.2.2实现生成多张缩略图的方法

maxSize = 3000000 ;// 设置附件上传大小 C('UPLOAD_SIZE'); //$upload->savePath = './Public/Uploads/' . $path; // 设置附件上传目录 $upload->savePath = './Public/Uploads/' . 'thumb/'; // 设置附件上传目录 $upload->allowExts = array('jpg','gif','png','jpeg'); // 设置附件上传类型 $upload->saveRule = 'time'; $upload->uploadReplace = true; //是否存在同名文件是否覆盖 $upload->thumb = true; //是否对上传文件进行缩略图处理 $upload->thumbMaxWidth = '100,300'; //缩略图处理宽度 $upload->thumbMaxHeight = '50,150'; //缩略图处理高度 //$upload->thumbPrefix = $prefix; //缩略图前缀 $upload->thumbPrefix = 'm_,s_'; //生产2张缩略图 //$upload->thumbPath = './Public/Uploads/' . $path . date('Ymd',time()) . '/'; //缩略图保存路径 $upload->thumbPath = './Public/Uploads/' . 'thumb/' . date('Ymd',time()) . '/'; //缩略图保存路径

//$upload->thumbRemoveOrigin = true; //上传图片后删除原图片
$upload->thumbRemoveOrigin = false; //上传图片后删除原图片
$upload->autoSub = true; //是否使用子目录保存图片
$upload->subType = 'date'; //子目录保存规则
$upload->dateFormat = 'Ymd'; //子目录保存规则为date时时间格式

if (!$upload->upload()) {// 上传错误提示错误信息 echo json_encode(array('msg' => $this->error($upload->getErrorMsg()),'status' => 0)); } else {// 上传成功 获取上传文件信息 $info = $upload->getUploadFileInfo(); $picname = $info[0]['savename'];

$picname = explode('/',$picname);
//$picname = $picname[0] . '/' . $prefix . $picname[1];
$picname = $picname[0] . '/' . '_hz' . $picname[1];
