Save radio button status php
<p>Form table is introduced inside an echo and, for the texts fields, I use value=" ' .$_POST['name'] to set default value if form was already sent at least one time. It works properly.
However, how could I save radio buttons status when form was already sent? Thanks.</p>

<pre><code>&lt;tr&gt;
&lt;td colspan="2" align="left" valign="top"&gt; &lt;input type="radio" name="ambiente" value="si" /&gt;
         Si
&lt;input type="radio" name="ambiente" value="no" /&gt;
       No&lt;/td&gt;
&lt;/tr&gt;
</code></pre>
