Would like to use isset(empty($sc))
<p>I want to use a combination of this <code>isset(empty($sc))</code> but am receiving this error </p>

<blockquote>
  <p>Parse error: syntax error, unexpected T_EMPTY in /var/www/html/find.php on line 9</p>
</blockquote>

<p>When someone posts from the form, then the <code>$sc</code> should be checked if empty only if the form has been submitted.</p>
