Postbacks in PHP
<p>Is there a way to check which link/button was clicked from a form besides using </p>

<pre><code>if(isset($_POST['myvar']))
{
//if true do this
}
else
{//do this}
</code></pre>

<p>or a querystring? </p>

<p>My page has a jquery drop down and thus the above isset function is not working as the form for login is contained in the dropdown.</p>
