Access form input in the same form
<p>I am taking input from user in a form. Can I get that value(user input) to calculate other fields in the same form.</p>

<pre><code>&lt;input size="12" id="inputField" name="inputField"  autofocus="" type="date"     onblur="return dateValidate(this)"/&gt;
</code></pre>

<p>Can I collect this form input later in the form and use it to calculate other fields. I was trying to using to use <code>$_POST</code> to retrieve the value but I am not sure if thuis is the right thing.</p>
