You can create a link like this:

<a href="page.php?var=value">Go</a>

The variable-value pair after ? will create the query string. Later you can get the query string with $_GET array like $_GET['var'] for example.

There are several ways to do that:

1. For links: pass "uid" as GET parameter in all links: <a href='something.php?uid=$uid ... '

2. For forms: pass "uid" as POST parameter, this can be done with <input type='hidden' name='uid' value='$uid'>

3. Also, you may use cookies, see the following article for details: http://php.net/manual/en/function.setcookie.php
