注意:Unknown:在系统临时目录下第 0 行 Unknown 中创建的文件

Notice: Unknown: file created in the system's temporary directory in Unknown on line 0

这是我的 HTML:

<form name="import" method="post" action="CSVUpload" enctype="multipart/form-data">
    <input type="file" name="file" /><br />
    <input type="submit" name="submit" value="Submit" />
</form>

路线如下:

$f3->route('POST|PUT @CSVUpload: /CSVUpload', 'GBDInternalsControllersLeaveController->csvHandler');
$f3->route('GET /CSVUpload', 'GBDInternalsControllersLeaveController->csv');

这是我的控制器:

public function csv()
{
    $this->f3->set('content', 'leave/csvUploader.php');
    $template = new View;
    echo $template->render('dashboard/layout.php');
}

public function csvHandler()
{
    $postvalue = $this->f3->get('POST.submit');
    if(isset($postvalue))
    {
        $fileReceived = $this->f3->get('POST.file');
        var_dump($fileReceived);
    }
}

我使用的是无脂肪框架.
