To hide some payment methods based on shipping method you don't need to observe things at all:
Every methods(in one page check out) post the methods which are chosen to the next level. So you can get the shipping method which are chosen, in payment method level. Just print the post things in
app/design/frontend/base/default/template/checkout/onepage/payment/methods.phtml
in this add below one,
<?php print_r($_POST); ?>
So now you can get the shipping methods which are chosen previous step. And note it, so now, you can add just simple logic (if else) condition in same file for hiding payment.
For example here I want hide check / money order payment method, if shipping method is flat. Here the payment method code is checkmo. you can get payment method code by simply printing that variable like echo $_code = $_method->getCode(); in same file. so here just add simple if else ,
<?php
$methods = $this->getMethods();
$oneMethod = count($methods) <= 1;
?>
<?php if (empty($methods)): ?>
<dt>
<?php echo $this->__('No Payment Methods') ?>
</dt>
<?php else:
foreach ($methods as $_method):
echo $_code = $_method->getCode();
if($_POST['shipping_method'] == 'flatrate_flatrate') {
if($_code == 'checkmo') {
continue;
}
}
?>
Here,
if($_POST['shipping_method'] == 'flatrate_flatrate') {
if($_code == 'checkmo') {
continue;
}
}
checks the shipping method and skip the payment method which we don't want to display. That's it. Please comment here if you have any doubt.
Note:
shipping_method => flatrate_flatrate
payment_method => checkmo

It's not intended. If you look at the template
app/design/frontend/base/default/template/checkout/onepage/shipping_method/available.phtmlwhich shows the available shipping methods, no additional blocks are loaded and there is no kind of hook to change the HTML either. You would have to replace this template and implement something on your own.Another possibility is to add custom fields to the shipping_method form that are not related to a specific shipping method, in the block
checkout.onepage.shipping_method.additional. Unfortunately this one doesn't render its children by default, like I would expect from an "additional" block, but this requires only little change:Copy
app/design/frontend/base/default/template/checkout/onepage/shipping_method/additional.phtml, addecho $this->getChildHtml()at the end and replace it in your modules layout XML file.Then you can add new blocks inside it with anything you want. You could also use JavaScript to display the form only if a specific shipping method is selected.
