Delete file immidiatly after download

[nadeemshafi9]

i would like to delete or set permissions on a file immediately after download, i am creating a file and will allow the user to download it but it need to be deleted as soon as its downloaded, is there a way of doing this.

 

I was also wondering can you you create a file but not keep it on your server but just let the user download it.

 

i know JavaScript is involved.

 

can someone give me some plain English ideas. I basically want to stop people from manually downloading confidential data files yet allow the user to create dumps etc and download them.

 

thanks

if(is_file($directory_of_file)){
unlink($directory_of_file);
}

You really cannot be sure if the download is complete, but you can dump the file to browser and then delete it after you dump it. Something like...

 

<?php

ignore_user_abort ();

set_time_limit ( 0 );

$file_path = './path/to/file.pdf';

$file_type = 'application/pdf';

$file_name = 'document.pdf';

header ( 'Cache-Control: max-age=31536000' );

header ( 'Expires: Mon, 26 Jul 1997 05:00:00 GMT' );

header ( 'Content-Length: ' . filesize ( $file_path ) );

header ( 'Content-Disposition: filename="' . $file_name . '"' );

header ( 'Content-Type: ' . $file_type . '; name="' . $file_name . '"' );

readfile ( $file_path );

unlink ( $file_path );

exit ();

?>
