uploadify上传预览+缩略图+水印实例
首先感谢各位大神网友的分享,我只是改改代码,让其更符合自己的业务逻辑
图片上传+缩略图+水印处理代码:
    //文件上传
    Public function _upload( $thumb = false , $thumbWidth = '' , $thumbHeight = '') {
        $upload = new \Think\Upload();// 实例化上传类
        $upload->maxSize = 3145728 ;// 设置附件上传大小
        $upload->exts =  array('jpg', 'gif', 'png', 'jpeg');// 设置附件上传类型
        $upload->savePath =  '/' . CONTROLLER_NAME .'/'; // 设置附件上传目录
        $info = $upload->upload();
        if(!$info) {
            return array('status' =>0, 'info'=> $upload->getError() );
        }else{
            if( $thumb ) {    //生成缩略图

                $image = new \Think\Image(); 

                foreach($info as $file) {
                    $thumb_file = './Uploads/' . $file['savepath'] . $file['savename'];
                    $save_path = './Uploads/' .$file['savepath'] . 'mini_' . $file['savename'];
                    $image->open( $thumb_file )->text('德兴房产','./data/1.otf',30,'#A7AAA4',\Think\Image::IMAGE_WATER_SOUTHWEST)->save( $thumb_file );
                    $image->open( $thumb_file )->text('德兴房产','./data/1.otf',24,'#A7AAA4',\Think\Image::IMAGE_WATER_SOUTHWEST)->thumb( $thumbWidth, $thumbHeight )->save( $save_path );
                    return array(
                        'status' => 1, 
                        'savepath' => $file['savepath'],
                        'savename' => $file['savename'],
                        'pic_path' => $file['savepath'] . $file['savename'],
                        'mini_pic' => $file['savepath'] . 'mini_' .$file['savename']
                    );   
                }
            }else{
                foreach($info as $file) {
                    return array(
                        'status' => 1, 
                        'savepath' => $file['savepath'],
                        'savename' => $file['savename'],
                        'pic_path' => $file['savepath'].$file['savename']
                    );   
                }
            }
        }
    }
前端主要代码(参考http://www.thinkphp.cn/code/151.html):

                                        <div class="form-group">
                                            <input type="file" id="upload" class="form-control input-medium" />
                                        </div>
                                        <div style="width:100%; float:left;padding:10px 20px 20px; background-color:#ccc">

                        </div> <!-- END #TAB3 -->

                        <div class="margin-top-10">
