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);
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);
在 MayFish 里的使用实例：
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');
}
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');
}
