Hi,
I am having trouble, in fact absolutely no success, using my php
script create friendships. If you could find the error in my code/
give me a code that works I would greatly appreciate it!
In the code below the update function works perfectly but the
followers and create function don't work at all.
Below is my code:
$uname = $_POST['username'];
$upass = $_POST['pass'];
include("./Twitter.class.php");
$twitter = new Twitter();
$twitter->username = $uname;
$twitter->password = $upass;
// Show public timeline
echo $twitter->followers('xml');
// Update your status
echo $twitter->update('xml','Just increased my followers...');
// Start following a user
echo $twitter->create('xml','commonsensegov');
As you can see I am using twitter.class.php which I have included
below:
