//jquery部分
$("input[type='file']").ajaxfileupload({
    action: "{:U('Portal/News/ajaxFileUpload')}",
    params: {
        extra: 'info'
    },
    onComplete: function(res) {

        if (res.code == '0'){
            path = res.res['0'];
            var img = "<img src='"+path+"'>";
            $(this).parent().next().html(img)
        } else{
            alert(res.msg)
        }
    },

});

php部分：

public function ajaxFileUpload(){
        $upload = new \Think\Upload();// 实例化上传类

        $upload->maxSize   =     10485760 ;// 设置附件上传大小 10M
        $upload->exts      =     array('zip', 'rar', '7z','jpg','jpeg','png','gif');// 设置附件上传类型
        $upload->rootPath  =     C('UPLOADPATH'); // 设置附件上传根目录
        $upload->savePath  =     'guestbook/'; // 设置附件上传（子）目录
        // 上传文件 
        $info   =   $upload->upload();
        if(!$info) {// 上传错误提示错误信息
            ajaxReturn('1',$info);
        }else{// 上传成功
            $re = array();
            foreach ($info as $k => $v) {
                $re[] = sp_get_asset_upload_path($v['savepath'] . $v['savename']);
            }
            ajaxReturn('0','success',$re);
        }
    }

    private function upload(){

        $upload = new \Think\Upload();// 实例化上传类

        $upload->maxSize   =     10485760 ;// 设置附件上传大小 10M
        $upload->exts      =     array('zip', 'rar', '7z','jpg','jpeg','png','gif');// 设置附件上传类型
        $upload->rootPath  =     C('UPLOADPATH'); // 设置附件上传根目录
        $upload->savePath  =     'guestbook/'; // 设置附件上传（子）目录
        // 上传文件 
        $info   =   $upload->upload();

        if(!$info) {// 上传错误提示错误信息
            return '';
        }else{// 上传成功
            $re = array();
            foreach ($info as $k => $v) {
                $re[] = $v['savepath'] . $v['savename'];
            }
