1.下载Uploadify 版本3.2.1 

2.下载七牛SDK 解压后将 qiniu 文件夹copy到uploadify文件夹下

3.修改uploadify.php文件

<?php

$verifyToken = md5(‘unique_salt‘ . $_POST[‘timestamp‘]);

if (!empty($_FILES) && $_POST[‘token‘] == $verifyToken) {
    $tempFile = $_FILES[‘Filedata‘][‘tmp_name‘];
    //生成新的文件名 
    $filename = time().mt_rand(10,99).‘.‘.end(explode(‘.‘, $_FILES[‘Filedata‘][‘name‘]));
    
    $fileTypes = array(‘jpg‘,‘jpeg‘,‘gif‘,‘png‘);
    $fileParts = pathinfo($_FILES[‘Filedata‘][‘name‘]);

    if (in_array($fileParts[‘extension‘],$fileTypes)) {
        //上传图片到云端 start
        require_once("qiniu/io.php");
        require_once("qiniu/rs.php");

        $bucket = "abc";//空间名
        //截取原始文件后缀名
        $key1 = "Uploads/".$filename;
        $accessKey = ‘X3X89F2xQlca63vmIfNtxmqPkJ9TKHNKE-XYzPjH‘; //AK
        $secretKey = ‘O90SCQPjeONRFb1Ka15L1GK8qndACuo0C2lehngV‘; //SK

        Qiniu_SetKeys($accessKey, $secretKey);
        $putPolicy = new Qiniu_RS_PutPolicy($bucket);
        $upToken = $putPolicy->Token(null);
        $putExtra = new Qiniu_PutExtra();
        $putExtra->Crc32 = 1;
        //$tempFile uploadify上传的临时文件路径
        list($ret, $err) = Qiniu_PutFile($upToken, $key1, $tempFile, $putExtra);
        //上传图片到云端 end

        //返回文件名给前台
        echo "http://abc.qiniudn.com/".$key1; //前台使用回调函数的data参数接收
    } else {
        echo ‘Invalid file type.‘;
    }
}

前台代码 上传一个文件并显示到IMG标签中

<table style="border:none;" >
                <tr>
                    <td><img width="100" height="100" id="timg"/></td>
                    <td width=100%>
                        <script src="__STATIC__/uploadify/jquery.uploadify.js" type="text/javascript"></script>
                        <link rel="stylesheet" type="text/css" href="__STATIC__/uploadify/uploadify.css">
                        <div id="queue"></div>
                        <input id="file_upload" name="file_upload" type="file" multiple="true">
                        <script type="text/javascript">
                        <?php $timestamp = time();?>
                        $(function() {
                            $(‘#file_upload‘).uploadify({
                                ‘formData‘     : {
                                    ‘timestamp‘ : ‘<?php echo $timestamp;?>‘,
                                    ‘token‘     : ‘<?php echo md5(‘unique_salt‘ . $timestamp);?>‘
                                },
                                ‘swf‘      : ‘__STATIC__/uploadify/uploadify.swf‘,
                                ‘uploader‘ : ‘__STATIC__/uploadify/uploadify.php‘,
                                ‘onUploadSuccess‘ : function(file,data,response) {
                                    $("#timg").attr("src",data);
                                    $("#txtimg").val(data);
                                }
                            });
                        });
                        </script>
                    </td>
                </tr>
            </table>
