It's all about the headers... I use the following:
function uploadStream( $filename=null, $csv=null )
{
if( $csv === null )
{
$csv = $this->csv;
}
if( $filename === null )
{
$filename = 'download.csv';
}
header( "Content-type: text/csv" );
header( "Content-disposition: inline; filename=$filename" );
echo $csv;
exit();
}
You can feel free to adapt it since I ripped it out of my CSV writer
service and so it won't work as-is.
Cheers,
Rob.
