Symfony - 如何通过PHP表单上传处理收到的文件

Question

I have to write a controller that receives a CSV file. When I POST the file via Postman, I know how to handle the file in Symfony:

    if ($this->getRequest()->files) {
        $filename = date('Ymd').'-filename.csv';
        $directory = $this->container->getParameter('kernel.root_dir').'/';
        $request = $this->get('request');
        $data = $request->getContent(); 
    }

If the file is uploaded via a PHP form upload like this:

    <form action="{{path('import_csv_file')}}" method="POST" enctype="multipart/form-data">
     Select file to upload:
     <input type="file" name="fileToUpload" id="fileToUpload">
     <input type="submit" value="Upload CSV File" name="submit">
    </form>

How can I handle the file in the controller? Thanks!

Your files are stored in $request. Is an array if you sent multiple files and is an UploadedFile(); if file is just one. The array is an UploadedFile() collection.

public function yourAction(Request $request)
{
    $file = $request->files;
}
