thinkphp 縮略圖上傳

//公共上傳
    private function _upload($width, $height, $path, $prefix) {
        import('ORG.Net.UploadFile');
        $upload = new UploadFile(); // 實例化上傳類
        $upload->maxSize = C('UPLOAD_SIZE'); // 設置附件上傳大小
        $upload->savePath = './Uploads/' . $path; // 設置附件上傳目錄
        $upload->allowExts = array('jpg', 'gif', 'png', 'jpeg'); // 設置附件上傳類型
        $upload->saveRule = 'time';
        $upload->uploadReplace = true; //是否存在同名文件是否覆蓋
        $upload->thumb = true; //是否對上傳文件進行縮略圖處理
        $upload->thumbMaxWidth = $width; //縮略圖處理寬度
        $upload->thumbMaxHeight = $height; //縮略圖處理高度
        $upload->thumbPrefix = $prefix; //縮略圖前綴
        $upload->thumbPath = './Uploads/' . $path . date('Ymd', time()) . '/'; //縮略圖保存路徑
        $upload->thumbRemoveOrigin = true; //上傳圖片後刪除原圖片
        $upload->autoSub = true; //是否使用子目錄保存圖片
        $upload->subType = 'date'; //子目錄保存規則
        $upload->dateFormat = 'Ymd'; //子目錄保存規則爲date時時間格式
 
 
        if (!$upload->upload()) {// 上傳錯誤提示錯誤信息
            echo json_encode(array('msg' => $this->error($upload->getErrorMsg()), 'status' => 0));
        } else {// 上傳成功 獲取上傳文件信息
            $info = $upload->getUploadFileInfo();
            $picname = $info[0]['savename'];
             
            $picname = explode('/', $picname);
            $picname = $picname[0] . '/' . $prefix . $picname[1];
            echo json_encode(array('status' => 1, 'msg' => $picname));
             
             
             
             
             
        }
    }

然後你比如生成300*300的的圖片你就定義一個方法

例如： //商品縮略圖上傳
    public function uploadThumb() {
        return $this->_upload('230,160', '230,121', 'thumb/', 'shop_,thumb_');
    }

然後400*400的就又寫一個方法：

 //商品縮略圖上傳
    public function uploadThumb() {
        return $this->_upload('400,200', '400,200', 'thumb/', 'shop_,thumb_');
    }

protected function _upload($fileToUpload, $width, $height, $path, $prefix) {
		$fileElementName=$_FILES[$fileToUpload];
		$upload = new \Think\Upload();// 實例化上傳類
		$upload->maxSize = '3145728'; //C('UPLOAD_SIZE'); // 設置附件上傳大小
		$upload->savePath = './Uploads/' . $path; // 設置附件上傳目錄
		$upload->allowExts = array('jpg', 'gif', 'png', 'jpeg'); // 設置附件上傳類型
		$upload->saveRule = 'time';
		$upload->uploadReplace = true; //是否存在同名文件是否覆蓋
		$upload->thumb = true; //是否對上傳文件進行縮略圖處理
		$upload->thumbMaxWidth = $width; //縮略圖處理寬度
		$upload->thumbMaxHeight = $height; //縮略圖處理高度
		$upload->thumbPrefix = $prefix; //縮略圖前綴
		$upload->thumbPath = './Uploads/' . $path . date('Y/Y-m-d', time()) . '/'; //縮略圖保存路徑
		$upload->thumbRemoveOrigin = true; //上傳圖片後刪除原圖片
		$upload->autoSub = true; //是否使用子目錄保存圖片
		$upload->subType = 'date'; //子目錄保存規則
		$upload->dateFormat = 'Ymd'; //子目錄保存規則爲date時時間格式
	
		$info   =   $upload->uploadOne($fileElementName);
		if (!$info) {// 上傳錯誤提示錯誤信息
			$error = $this->error($upload->getError());
		} else {// 上傳成功 獲取上傳文件信息
			$info = $upload->getUploadFileInfo();
			$msg = $info['savepath'].$info['savename'];	 
		}
    }
