Hello,

I am developing a web site with codeigniter.

I have a form where I have a few group radio buttons.

When validation fails, one group radio keeps its value but the other doesn't.

I can't find why.

My code for the radio that does not work:

<label for="accommodationYes" class="accomm" id="accommY">
    <input name="accommodation" type="radio" id="accommodationYes" style="display:none;" value="Yes"<?php set_radio('accommodation', 'Yes'); ?>>
    <span class="custom radio"></span> Yes
</label>
<label for="accommodationNo" class="accomm" id="accomN">
    <input name="accommodation" type="radio" id="accommodationNo" style="display:none;" value="No"<?php set_radio('accommodation', 'No'); ?>>
    <span class="custom radio"></span> No
</label>

My code for the radio group that does work:

 <label for="eft"><input name="payment" type="radio" id="eft" style="display:none;" value="EFT"<?php echo set_radio('payment', 'EFT'); ?>><span class="custom radio"></span> EFT</label>
 <label for="cash"><input name="payment" type="radio" id="cash" style="display:none;" value="Cash"<?php echo set_radio('payment', 'Cash'); ?>><span class="custom radio"></span> Cash</label>
 <label for="cheque"><input name="payment" type="radio" id="cheque" style="display:none;" value="Cheque"<?php echo set_radio('payment', 'Cheque'); ?>><span class="custom radio"></span> Cheque</label>

My validation code:

$this -> form_validation -> set_rules('accommodation', 'Accommodation', 'required|xss_clean' );     
$this -> form_validation -> set_rules('payment', 'Payment', 'required|xss_clean' ); 

Can someone please help me find the problem?

You are missing the echo in the first group:

<label for="accommodationYes" class="accomm" id="accommY">
<input name="accommodation" type="radio" id="accommodationYes" style="display:none;" value="Yes"<?php echo set_radio('accommodation', 'Yes'); ?>>
<span class="custom radio"></span> Yes
</label>
<label for="accommodationNo" class="accomm" id="accomN">
    <input name="accommodation" type="radio" id="accommodationNo" style="display:none;" value="No"<?php echo set_radio('accommodation', 'No'); ?>>
    <span class="custom radio"></span> No
</label>

EDIT
You don't even imagine what I've done to find this.. I didn't think about echo until I checked all the mechanism.. LOL! I'm pasting my previous text just to let you see how much dumb I'm feeling now x_x :D

========================================================================

It seems a bug but I don't understand why, I made a test and I got your same results, here's my code.

The Controller
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Test extends CI_Controller
{

    public function start()
    {
        $this->load->helper(array('form', 'url'));
        if(validation_errors())
        {
            $error_object =& _get_validation_object();
            $d['errors'] = $error_object;
        }
        else
        {
            $d['errors'] = false;
        }
        $this->load->view('test/start',$d);
    }

    public function form()
    {
        $this->load->helper(array('form', 'url'));
        $this->load->library('form_validation');

        $this->form_validation->set_rules('name', 'Name', 'required|xss_clean');
        $this->form_validation->set_rules('accommodation', 'Accommodation', 'required|xss_clean' );     
        $this->form_validation->set_rules('payment', 'Payment', 'required|xss_clean' ); 
        $this->form_validation->set_error_delimiters('<li>', '</li>');

        if($this->form_validation->run() === FALSE)
        {
            $this->start();
        }
    }
}
The View
<!DOCTYPE html>
<html>
<head></head>
<body>
<?php

    echo form_open('/test/form');
?>
<label for="name">Name <input type="text" name="name" /></label>
<label for="accommodationYes" class="accomm" id="accommY">
    <input name="accommodation" type="radio" id="accommodationYes" value="Yes"<?php set_radio('accommodation', 'Yes'); ?>>
    <span class="custom radio"></span> Yes
</label>
<label for="accommodationNo" class="accomm" id="accomN">
    <input name="accommodation" type="radio" id="accommodationNo" value="No"<?php set_radio('accommodation', 'No'); ?>>
    <span class="custom radio"></span> No
</label>
 <label for="eft"><input name="payment" type="radio" id="eft" value="EFT"<?php echo set_radio('payment', 'EFT'); ?>><span class="custom radio"></span> EFT</label>
 <label for="cash"><input name="payment" type="radio" id="cash" value="Cash"<?php echo set_radio('payment', 'Cash'); ?>><span class="custom radio"></span> Cash</label>
 <label for="cheque"><input name="payment" type="radio" id="cheque" value="Cheque"<?php echo set_radio('payment', 'Cheque'); ?>><span class="custom radio"></span> Cheque</label>
 <input type="submit" name="submit" value="submit" />
</form>
<?php

    # $_POST
    echo '<pre>';
    print_r($_POST);
    echo '</pre>';

    # this will print the validation object
    echo '<pre>';
    print_r($errors);
    echo '</pre>';
?>
</body>
</html>
Output

Now, if you run this:

you end in http://localhost/test/form and get the My_Form_validation Object from which it appears the selected radios:

[_field_data:protected] => Array
    (
        [name] => Array
            (
                [field] => name
                [label] => Name
                [rules] => required|xss_clean
                [is_array] => 
                [keys] => Array
                    (
                    )

                [postdata] => 
                [error] => The Name field is required.
            )

        [accommodation] => Array
            (
                [field] => accommodation

                [is_array] => 
                [keys] => Array
                    (
                    )

                [postdata] => Yes
                [error] => 
            )

        [payment] => Array
            (
                [field] => payment
                [label] => Payment
                [rules] => required|xss_clean
                [is_array] =>

                [postdata] => Cash
                [error] => 
            )

    )

[_config_rules:protected] => Array
    (
    )

[_error_array:protected] => Array
    (
        [name] => The Name field is required.
    )
MY_form_helper.php

So I did a little edit to form_helper.php, I placed MY_form_helper.php inside /application/helpers/ writing this:

<?php

function set_radio($field = '', $value = '', $default = FALSE)
{
    $OBJ =& _get_validation_object();

    if ($OBJ === FALSE)
    {
        if ( ! isset($_POST[$field]))
        {
            if (count($_POST) === 0 AND $default == TRUE)
            {
                return ' checked="checked"';
            }
            return '';
        }

        $field = $_POST[$field];

        if (is_array($field))
        {
            if ( ! in_array($value, $field))
            {
                return '';
            }
        }
        else
        {
            if (($field == '' OR $value == '') OR ($field != $value))
            {
                return '';
            }
        }

        return ' checked="checked"';
    }

    # this is what I modified:
    $a = $OBJ->set_radio($field, $value, $default);
    $b = array(
        'field'     => $field,
        'value'     => $value,
        'default'   => $default,
        'return'    => $a
    );
    log_message('debug',json_encode($b));
    return $a;
}
End Results

Then I checked the /applications/logs/log-2013-02-01.php and this is the output:

DEBUG - 2013-02-01 16:34:40 --> {"field":"accommodation","value":"Yes","default":false,"return":""}
DEBUG - 2013-02-01 16:34:40 --> {"field":"accommodation","value":"No","default":false,"return":" checked=\"checked\""}
DEBUG - 2013-02-01 16:34:40 --> {"field":"payment","value":"EFT","default":false,"return":" checked=\"checked\""}
DEBUG - 2013-02-01 16:34:40 --> {"field":"payment","value":"Cash","default":false,"return":""}
DEBUG - 2013-02-01 16:34:40 --> {"field":"payment","value":"Cheque","default":false,"return":""}

As you see it returns checked="checked" for the values I tested i.e.: No and EFT and for some reason it doesn't ECHO! O_O
