Hi!
I have a PHP script I've downloaded from somewhere (don't remember where, but the developers link is dead) and I want to modify it. Actually I want an extra page.
The script has 2 files, tw.php and parse.php. In tw.php you should enter your twitter account (user+pass) and the feed you want to publish on twitter. That's it, just open it in the browser.
This is very useful for me, but... I want to share it with my site's visitors, so I need a third page where people can submit their informations (twitter, pass, feed) to publish their feed on their sites. A form, basically, nothing more. But since I don't know PHP I cannot do it myself.
So, can someone, please, make the third page for me or modify the tw.php in order to allow it to do that?
Thank you very much! if is not possible, I hope at least it will be useful to others.
TW.php
