Thinkphp多文件上传实现方法
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。

"Development Suggestions: How to Use the ThinkPHP Framework to Implement Asynchronous Tasks" With the rapid development of Internet technology, Web applications have increasingly higher requirements for handling a large number of concurrent requests and complex business logic. In order to improve system performance and user experience, developers often consider using asynchronous tasks to perform some time-consuming operations, such as sending emails, processing file uploads, generating reports, etc. In the field of PHP, the ThinkPHP framework, as a popular development framework, provides some convenient ways to implement asynchronous tasks.
