Magento - OnePage Checkout - Hide Payment method d

问题:

I have asked this question on Magento Stackexchange without any success, hence me now asking here.

---

I'm using Magento Community Edition 1.9.0.1 and have correctly created and registered my module, but I can't seem to detect the shipping methods. Basically, I want to hide Cash on Delivery if Flat Rate or Free Shipping is chosen. Here is the code I have for my observer class:

class Kol_PaymentToggle_Model_Observer
{
    public function paymentMethodIsActive(Varien_Event_Observer $observer) {
        $event  = $observer->getEvent();
        $method = $event->getMethodInstance();
        $result = $event->getResult(); 
        $quote = $observer->getEvent()->getQuote();
        $shippingMethod = $quote->getShippingAddress()->getShippingMethod();
        if($shippingMethod == "standardshipping" || $shippingMethod == "free") {
            if($method->getCode() == 'cashondelivery' ) {
                $result->isAvailable = false;
            }
        }
    }
}

I'm guessing that I haven't used the correct shipping method code names or payment method code names, but I'm unsure. Anyone has any advice?

EDIT: I only have 3 shipping methods enabled:

• Collect In Store
  Title = Collect in Store
  Method Name = Collect In Store (Extension link)
• Flat Rate
  Title = Standard Delivery
  Method Name = Standard Shipping
• Free Shipping
  Title = Free Delivery
  Method Name = Free

EDIT 2: Output of config.xml

<?xml version="1.0"?>
<config>
    <modules>
        <Kol_PaymentToggle>
            <version>0.0.1</version>
        </Kol_PaymentToggle>
    </modules>
    <frontend>
        <events>
            <payment_method_is_active>
                <observers>
                    <paymentfilter_payment_method_is_active>
                        <type>singleton</type>
                        <class>Kol_PaymentToggle_Model_Observer</class>
                        <method>paymentMethodIsActive</method>
                    </paymentfilter_payment_method_is_active>
                </observers>
            </payment_method_is_active>
        </events>
    </frontend>
</config>

Hopefully this extra information can prove useful towards helping me!

As for I got, you trying to hide some payment methods based on shipping method. For this you don't need to observe things at all. Simply you can do this, just follow me,

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
 paymet_method   => checkmo

Though the accepted answer works, it is not an elegant solution since it prompts us to check the post data in a phtml file which is not a good method. Instead, you should definitely look for an event to do this job.

Luckily we have a perfect event to do this job and which is payment_method_is_active. Please see the detailed answer here.

Basically, you need to set the payment method inactive through this method as you can see in the answer.

In addition to the solution for the OnePage Checkout IWD provided by @Simbus82:

$shipping = Mage::getSingleton('checkout/session')->getQuote()->getShippingAddress()->getShippingMethod();

foreach ($methods as $_method): 
        $_code = $_method->getCode(); 
        if ( $shipping == 'matrixrate_matrixrate_140' or $shipping == 'matrixrate_matrixrate_148' ) { 
            if($_code != 'cashondelivery') { 
                continue;   
            } 
        }
