How to add "Tweet This" to a node
Ever wanted to add a "Tweet This" to your nodes? Here is how I did it at somoscanada.com. This short tutorial is for people using Drupal.
Open the file node.tpl.php, located under your active theme(sites > all > themes).
At line 96 approximately, add this code(you need to type it!), just before "<?php if ($terms): ?>">. And I am using the Zen theme:
Replace http://somoscanada.com to your domain.
I am using URL Alias(Path module), that's why you see "echo $node->path", it prints the node alias. If you are not using the Path module, then replace that with "php print $node->nid", it prints node/ID.
Last, upload the file node.tpl.php to your server. If you do not see that changes, go to "Site Information > Performance >", empty your cached data.
