Im trying to display a number fetched from the database (which i can do just fine) but how do I only display it on the original post? Im using the postbit hook. What I want basically is for a user set number to show up on the threads OP. Any idea?

if($postcounter == 1)
{
    //do something
}

or

if($thread['dateline'] == $post['dateline'])
{
    //do something
}
