Saving the values of form elements after an incomplete submission

[Fernando Rodríguez]

Hi,

I'm writing a form that requires validation. After submission, the form fields
(mostly textboxes) are validated and if any is incorrect, the form is redisplayed
with all the value sin place so the user doesn't have to retype everything.

I'm achieving the latter this way:

<input type="text" name="whatever" value="<?php echo $_POST['whatever']
?>" >

This is fine with text boxes, but how can I do this with listboxes and option
buttons?

Thanks

for list:
<select name="list">
<option value="value1"< ?php if($_POST["list"]=="value1") { echo"
selected"; } ?>>item1</option>
<option value="value2"< ?php if($_POST["list"]=="value2") { echo"
selected"; } ?>>item2</option>
</select>

for radio buttons:
<label><input name="radio" type="radio" value="radio1"< ?php
if($_POST["radio"]=="radio1") { echo" checked"; } ?>>radio1</label>
<label><input name="radio" type="radio" value="radio2"< ?php
if($_POST["radio"]=="radio2") { echo" checked"; } ?>>radio2</label>
