Javascript Validations

To add Canadian Specific Postal Code validation. TO: find solution that does not touch vanilla code.

find all files that solicit postal code. These include:

vi /var/www/shop/app/design/frontend/sm-fcstore/default/template/persistent/checkout/onepage/billing.phtml
vi /var/www/shop/app/design/frontend/sm-fcstore/default/template/customer/address/edit.phtml
vi /var/www/shop/app/design/frontend/sm-fcstore/default/template/checkout/onepage/shipping.phtml
vi /var/www/shop/app/design/frontend/sm-fcstore/default/template/persistent/customer/form/register.phtml
vi /var/www/shop/app/design/frontend/sm-fcstore/default/template/persistent/checkout/onepage/billing.phtml
vi /var/www/shop/app/design/frontend/sm-fcstore/default/template/opc/customer/form/register.phtml
vi /var/www/shop/app/design/frontend/sm-fcstore/default/template/opc/onepage/shipping.phtml
vi /var/www/shop/app/design/frontend/sm-fcstore/default/template/opc/onepage/billing.phtml

add new class called "validate-zip-code-canadian". You can safely remove class called "validate-zip-international"

<div class="input-box">
  <input type="text" title="<?php echo $this->__('Zip/Postal Code') ?>" 
  name="billing[postcode]" id="billing:postcode" value="
  <?php echo $this->escapeHtml($this->getAddress()->getPostcode()) ?>" 
  class="input-text validate-zip-code-canadian  validate-zip-international 
  <?php echo $this->helper('customer/address')->getAttributeValidationClass('postcode') ?>" />
  </div>

/var/www/shop/js/prototype/validation.js

add to end of file:

Validation.addAllThese([
 ['validate-zip-code-canadian', 'Canadian postal format is A9A 9A9.', function(v) {
            return Validation.get('IsEmpty').test(v.trim()) || /(^[A-Za-z]\d[A-Za-z][ -]?\d[A-Za-z]\d$)/.test(v.trim());
            }]
])

If you use multiple languages, add translation string into Mage_Core.csv and jstranslator.xml

vi /var/www/shop/app/code/core/Mage/Core/etc/jstranslator.xml     

<validate-zip-code-canadian translate="message" module="core">
	<message>Canadian postal format is A9A 9A9.</message>
</validate-zip-code-canadian>

vi /var/www/shop/app/locale/fr_FR/Mage_Core.csv  

"Canadian postal format is A9A 9A9.","Le format postal canadien est A9A 9A9."
