I have an application which I am working on which takes a file supplied by
the user via a File Upload, peforms some processing on it, then prompts the
user to download a generated CSV file. What I would like to do is report
some processing statistics prior to the user prior to sending the CSV steam.
My CSV export ends with this:
header("Content-type: application/vnd.ms-excel") ;
header("Content-disposition: attachment; filename=CSVData." .
date("Y-m-d").".csv") ;
print $csvStream ;
Unfortunately if I display any content prior to sending the CSV stream I get
the 'headers already sent' error message.
Is there a way to both display a web page and send content to be saved by
the user? If someone knows of an example I could look at I'd be greatful.
No, you cannot display both a webpage and send a file
on the same page to the user.
What you could do is save the processed file in a temporary
folder and provide a link to download the file in your processing
statistics page. Or, you could redirect the user to the file after
showing the statistics page.
