最新的文件上传模型，支持多文件上传
单独使用实例:
include 'uploaded.model.php'
;
$U = new UploadModel();
$U->target = '/tmp/' ;
$U->exts = 'jpg,gif' ;
$U->maxSize = 1024*275; //275KB
$U-> save();
$files = $U-> getFiles();
print_r($files);
$U = new UploadModel();
$U->target = '/tmp/' ;
$U->exts = 'jpg,gif' ;
$U->maxSize = 1024*275; //275KB
$U-> save();
$files = $U-> getFiles();
print_r($files);
在 MayFish 中的使用实例：
public function
up()
{
$U = M('SYS', 'upload' );
$U->target = '/tmp/' ;
$U->exts = 'jpg,gif' ;
$U->maxSize = 1024*275; //275KB
$U-> save();
header('Location:/?a=upload' );
}
HTML 代码
{
$U = M('SYS', 'upload' );
$U->target = '/tmp/' ;
$U->exts = 'jpg,gif' ;
$U->maxSize = 1024*275; //275KB
$U-> save();
header('Location:/?a=upload' );
}
