这篇文章主要介绍了Thinkphp多文件上传实现方法,是非常实用的技巧,需要的朋友可以参考下

本文实例讲述了Thinkphp多文件上传实现方法,分享给大家供大家参考。具体实现方法如下:

Thinkphp手册中对于多文件上传描述的很清楚:如果需要使用多个文件,只需要修改表单,,把

复制代码 代码如下:


改为

复制代码 代码如下:



  • 或者

    复制代码 代码如下:



  • 暂且自己的上传表单域为两个,一个上传图片,一个上传视频。字段名为image、video。
    html代码如下

    复制代码 代码如下:

    图片:
     
    视频:


    model代码:

    复制代码 代码如下:

    protected $info= '';
     
    protected $_auto = array(
    array('image','upload',3,callback),//自动完成方法
    array('video','videoupload',3,callback), //自动完成方法
    );//自动填充上传图片生成缩略图
    protected function upload(){
    $var = $_FILES['image']['name'];
    import('ORG.Net.UploadFile');
    $upload = new UploadFile();
    $upload->saveRule  = time;
    $upload->allowExts  = array('jpg', 'gif', 'png', 'zip','flv');
    $upload->thumb = true;
    //视频路径。。。只支持flv后缀,
    $upload->videopath = './Public/upload/Video/';
    $upload->savePath =  './Public/upload/images/';
    $upload->thumbPrefix = '250_115_,150_110_,213_156_';
    $upload->thumbMaxWidth='250,150,213';
    $upload->thumbMaxHeight='115,110,156';
    if(!in_array('',$var) || !in_array('',$_FILES['video']['name'])){
    if(!$upload->upload()) {
    echo $upload->getErrorMsg();die;
    }else{
    $this->info =  $upload->getUploadFileInfo();
    if(!in_array('',$var) && !in_array('',$_FILES['video']['name'])){
    return $this->info[1]['savename'];
    }elseif(!in_array('',$var)){
    return $this->info[0]['savename'];
    }else{
    return false;
    }
     
    }
    }else{
    return flase;
    }
    }
    //上传视频
    protected function videoupload(){
    if(!in_array('',$var) && !in_array('',$_FILES['video']['name'])){
    return $this->info[0]['savename'];
    }elseif(!in_array('',$_FILES['video']['name'])){
    return $this->info[1]['savename'];
    }else{
    return false;
    }
     
    }


    文章最后我来分析一下多文件上传原理吧,先来看看html代码

    复制代码 代码如下:




  • 这种就是把表单变量定义为数组,在php中数组特殊变量它可以存储多个不定长的内容,所以我们就可以自定多文件上传框了,那么在php处理时我们要如何操作,下面看例子。

    复制代码 代码如下:

    protected $_auto = array(
    array('image','upload',3,callback),//自动完成方法
    array('video','videoupload',3,callback), //自动完成方法
    );//自动填充上传图片生成缩略图


    这个是告诉thinkphp是数组变量了,并不需要像原生态的php中来判断遍历数组长度再一个个上传的代码了,因为了thinkphp己经做好了。

    希望本文所述对大家的ThinkPHP框架程序设计有所帮助。
