Hi, I am a newbie in PHP and currently developing a site that allow my users to download pic from my server. When users clicked on the hyperlink which links to a pic, that file will be downloaded automatically to the user's D:\\My Picture without pop-up a dialogue-box asking where the file should be saved.
I hope you guys can provide me sample code or direct me to any useful sites. Your reply is very much appreciated.
Thank you.
It is not possible to do this with PHP alone, as it would be a major secutiry risk.
The only way possible would be to have a program on the users computer that downloads the file, then you would be able to select where it would be saved, otherwise the answer is no.
Hi John,
Do you mean the one in http://www.webshots.com/ ?
If that is the case, how to make that desktop application communicates with my server. And do I still need PHP?
You don't need PHP, but there is no reason why PHP cannot be used on the server side part of your application. Communicating with a PHP script via a desktop application isn't actually that hard as you can tunnel the communication through HTTP.
You will require the use of Sockets (WinSock - for Windows) or RPC, such as SOAP of XML-RPC. If you have a look in the Distributed Computing Forum there are many examples and code which describe how to communicate with server side applications via HTTP.
Hi visualAd,
Thank you for your advice. I am still new in the socket programming. Haha. In fact, I only tried it in Linux platform. Not yet explore it in Windows platform.
So, if I wanna use DotNet to develop the desktop application, does Distributed Computing Forum still useful for me?
