Why serialize does not include submit button name?
<p>Why serialize (Jquery) does not include submit button name?</p>

<p>In PHP I normally do this:</p>

<pre><code>if (isset($_POST['submit_signup'])) {
    print_r($_POST);
    //Then check firstname, password, etc POSTS
}
</code></pre>

<p>That don't work, what is the solution to this?</p>
