Address line number validation on checkout / registering

[hielkio]

Hi Folks,

I'm really no developer so I need your help in this

Maybe it's very simple, but I can't get it to work.

What I'd like to achieve? A simple check if the addressline contains a number.

Some people forget to fill in their housenumber when checking out ... and in that case we can't send the product(s).

I thought it might be simple to use the built-in validation, in this case: 

'validate-number'               => 'Please enter a valid number in this field.'

So I edited this file:

app/design/frontend/ultimo/default/template/checkout/onepage/billing.phtml

<input type="text" title="<?php echo Mage::helper('core')->quoteEscape($this->__('Street Address')) ?>" name="billing[street][]" id="billing:street1" value="<?php echo $this->escapeHtml($this->getAddress()->getStreet(1)) ?>" class="input-text validate-number <?php echo $_streetValidationClass ?>" />

As you can see I added the class validate-number ... but it isn't working. As I said, I might be looking in the wrong way here Hope you can help me figure it out

How I like to resolve this, is by using two address lines instead of one. You can do this via System > Configuration > Customers > Customer Configuration. In the tab "Name and Address Options" you can set the value for "Number of Lines in a Street Address" to two. With some styling, it should be a problem to place them next to each other in the page. Depending on the way addresses are written where you live, you can set the validate-number on the first or second address field. And make both of them required, so people have to fill in both fields.

An example of the code I use for this is this:

<?php $_streetValidationClass = $this->helper('customer/address')->getAttributeValidationClass('street'); ?>
<li class="fields fields-<?php echo $this->helper('customer/address')->getStreetLines(); ?>">
    <?php if(!$formHelper->isFieldHidden('street1')): ?>
        <div class="input-box-help field street1">
            <label for="billing:street1" class="required"><em>*</em><?php echo $this->__('Address 1') ?></label>
            <div class="input-box">
                <input type="text" title="<?php echo $this->__('Street Address') ?>" name="billing[street][0]" id="billing:street1" maxlength="35" value="<?php echo $this->escapeHtml($_address->getStreet(1)) ?>" class="input-text <?php echo $_streetValidationClass ?>" />
            </div>
        </div>
    <?php endif; ?>

    <?php for ($_i = 2, $_n = $this->helper('customer/address')->getStreetLines(); $_i <= $_n; $_i++): ?>
        <?php if($_i > 2) $_streetValidationClass = trim(str_replace('required-entry', '', $_streetValidationClass)); ?>
        <div class="field street<?php echo $_i ?>">
            <label for="billing:street<?php echo $_i ?>"<?php if($_i < 3): ?> class="required"><em>*</em<?php endif; ?>><?php echo $this->__('Address '.$_i) ?></label>
            <div class="input-box input-box-help">
                <input type="text" title="<?php echo $this->__('Street Address %s', $_i) ?>" name="billing[street][<?php echo $_i - 1 ?>]" id="billing:street<?php echo $_i ?>" maxlength="10" value="<?php echo $this->escapeHtml($_address->getStreet($_i)) ?>" class="input-text validate-number <?php echo $_streetValidationClass ?>" />
            </div>
        </div>
    <?php endfor; ?>
</li>
