[dineshmatolia]

Hi

 

I confronted with a problem.When provide the image file for downloading to user, it does not ask for download it simply show the file content means show the image.

I include the below header in tpl file but it gives error like header already sent.

 

header("Content-Disposition: attachment; filename=$attachfile");

 

Kindly help me to solve this problem.

 

 

I am using smarty template with php. so I am to display the header into template file.

 

Thanks & Regards
