validation, radio button, and loops?

Code:

if ($_POST) {
// get post variables
echo $_POST['name'];
}else {
// get database results
echo $db_result->name;
}

the above won't work on radio buttons. you will need to echo a 'selected' so.... set_radio()

Code:

<?php foreach ($clients->result() as $client):?>
<option value="&lt;?php echo $client->id;?&gt;" &lt;?php if ($_POST) { echo $this->validation->set_radio('client', $invoice_detail->client_id);} else { echo( $invoice_detail->client_id == $client->id) ? 'selected' : '';}?&gt;>&lt;?php echo $client->name; ?&gt;</option>
&lt;?php endforeach;?&gt;

the above is if there is something selected from the database already.

Code:

<?php foreach ($clients->result() as $client):?>
<option value="&lt;?php echo $client->id;?&gt;" &lt;?php  echo $this->validation->set_radio('client', $invoice_detail->client_id);?&gt;>&lt;?php echo $client->name; ?&gt;</option>
&lt;?php endforeach;?&gt;

this one is if there is none.
