Open a Save/Download dialog using javascript

Hi lword,


You can't directly. You have to provide a download. When you click the link, you need to use PHP's header() function to send at least 2 headers.

1 - header('Content-type: xxx');
2 - header('Content-length: yyy');

xxx is the type of file being downloaded. If you don't want the browser to process it (either itself or by a plugin) you need to provide a type which is raw data. Maybe application/octet-stream.

yyy is the length of the data being sent. This is useful to show the user how long they have left to download.

Then you would use ...

readfile(zzz);

where zzz is the name of the file.

Richard Quadling.

Thanks Richard Quadling.

is it possible to do it in client-side i.e using Javascript / vbscript.?

i want the user to download the attachment
which is stored in the web server ,(and displayed in the inbox as attachments) to their
local hard disk by invoking the  open/save download dialog box.

Thanks
lword

You say "inbox". Can you explain what you mean by this?

hi  RQuadling

i'm developing a mail interface like gmail,yahoo etc.
Inbox is the place in which all the incoming mails , from the mail server , are displayed.
the incoming  mails from the mailserver is downloaded to the database and shown as inbox in the browser.
If the incoming mails received contains attachments, Iam storing it in the web server and displaying the file name
as attachment in the inbox.I want the user to download the attachments to the client (local hard disk by prompting the open/save disalog box ), by clicking on the attachment link in the inbox.
 
thanks
