Question

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.

<tr>
<td colspan="2" align="left" valign="top"> <input type="radio" name="ambiente" value="si" />
         Si
<input type="radio" name="ambiente" value="no" />
       No</td>
</tr>

Answer 1

Simply:

<input type="radio" name="ambiente" value="si" <?php if ($_POST['ambiente'] == 'si') echo 'checked'; ?> /> Si
<input type="radio" name="ambiente" value="no" <?php if ($_POST['ambiente'] == 'no') echo 'checked'; ?> /> No
