Question

I’m building a shopping cart, stuck on re-populating the country select input when user edits address.

In the controller:

public function loadCountryList() {

    $this->loadModel('GeoCountry');
    $geoCountryList = $this->GeoCountry->find('all', array(
        'recursive' => -1, 
        'order' => array('GeoCountry.name' => 'ASC')
    ));

    $geoCountries = array('Select Country' => array('US' => 'United States', 'CA' => 'Canada'));
    while(list($key,$row) = each($geoCountryList)) {
        $geoCountries['International Countries'][$row['GeoCountry']['id']] = $row['GeoCountry']['name'];
    }
    $this->set('geoCountries', $geoCountries);

}

The select on the checkout/edit address screen correctly renders a select with optgroups as structured in the controller and the values are correctly posted and saved in session as expected.

<?php echo $this->Form->input('geoCountries', array('class' => 'span3', 'label' => 'Billing Country', 'name' => 'data[Order][billing_country]', 'id' => 'OrderBillingCountry'));  ?>

And the output:

<select name="data[Order][billing_country]" class="span3" id="OrderBillingCountry">
<optgroup label="Select Country">
<option value="US">United States</option>
<option value="CA">Canada</option>
</optgroup>
<optgroup label="International Countries">
<option value="AF">Afghanistan</option>
….
</optgroup>
</select>

Using DebugKit, I can see the two letter country ISO code saved in Session:
billing_country CA

.. same for shipping_country …

But when I go back to the page, the value returns to “United States” (first value in the select …

So what am I missing??! I’ve been tearing my hair out on this one!

I suppose you are missing this part in controller:

$this->request->data['Order']['billing_country'] = ....;

in order to pass selected value to the view….

edit:
In view you have to also add default value like this:

<?php 
echo $this->Form->input('geoCountries', array(
  'class' => 'span3', 
  'label' => 'Billing Country', 
  'name' => 'data[Order][billing_country]', 
  'id' => 'OrderBillingCountry',
  'type' => 'select', 
  'default' => $this->data['Order']['billing_country']
));  
?>
