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

You want people to give you their twitter login details? Why? Personally, I would never use such a service as it is a cobbled solution and therefore open to security issues. Unless it was similar to a 'Facebook Connect'.
You use cURL, so it should be ok-ish, but I wouldn't trust it. Somebody providing this sort of functionality could be into id theft - sending info to their DB before logging the user on to twitter.

OK, perhaps I was a bit harsh. How about a form that allows up to 140 characters in a textarea:

Send the form - the post variable validates (and cleans if necessary) and redirects (via header) to something like:

$input = stripslashes($_POST['tweet']);
header("Location=http://twitter.com/home?status=$input");

THis *should* work if the user is logged in to twitter.

Thanks, but I don't need it. I can do what you wrote using only a form a javascript code, but what I want is (you haven't tried the script, haven't you?!) is to allow anybody to submit their feeds into their twitter accounts. I don't care about their passwords, actually if the autentification can be done through the twitter's api it would be better for me, too... but all I could find is this script and I don't know to modify it for my needs. I'm using it for myself now as a cron and it works perfect.

About the privacy, don't worry about twitter :) , worry about Google's decision to share its user information with the government agencies under the pretext of China's hacking attack. That's a dumb reason, IMHO. Next step is a CPU inserted in our ass to track us everywhere we go ;) - that's the privacy you should worry about.

Its also worth noting that API-password authentication is being phased out over the next 18 months so you are much better off setting up an application using the o-auth API
