I have an issue with my controller action that generates a CSV file using the league/csv package. Whenever I submit the form, the file can be downloaded successfully. However, if I try to submit the request again, I receive a CSRF token failure due to the expiration of the csrf code after each request. Can anyone suggest the best way to redirect the page after downloading the file in Slim framework for PHP?
$csv = \League\Csv\Writer::createFromFileObject(new \SplTempFileObject());
Data::where('user_id','=',$user_id)->get()->each(function($dat) use($csv) {
$data = $dat->toArray();
$data['link'] = $dat->getLink();
$csv->insertOne($data);
});
$csv->output('data.csv');
