$oid = ( isset($_GET['oid']) ) ? $_GET['oid'] : null;

Also I believe line 38 should come before line 37. bindParam calls a variable defined after it.

You use variable $oid which it's data is $_GET['oid'], in your query before you actually declare/store data to it.

Move line 38 -> $oid = $_GET['oid']; after opening try/catch, that means to line 29, before stating the query. You should implement @fie answer too, to be sure that $oid is not null and that data actually exists.

Also something is wrong with line 73 but we can't see it.
