Hi, change this line: > $connection->post('favorites/create', array('id' => $qtweet)); into: $connection->post('favorites/create/'.$qtweet);
> $qtweet = $_REQUEST['fav']; Make sure that $_REQUEST['fav'] is containing an existing ID. Check your Form: > <input style="width: 346px;" name="fav" id="fav" ></textarea> <input type="text" style="width: 346px;" name="fav" id="fav" value="<?php echo $YOUR_ID; ?>" /> I would prefer an input type="hidden". Hope it helps.
