如何将EAV值传递给Paypal支付信息

Question

I've introduced a custom EAV attribute for the customer object. Let's call it myvalue. Within several places in magento, I'm printing the value like this:

echo Mage::getSingleton('customer/session')->getCustomer()->getMyvalue();

When the customer pays with paypal, I'd like to have myvalue in the reason as an addition to the order number. My intent is to match the order with some shop-side process.

So, how can I pass myvalue to paypal to make it visible together with the order number?

You can try to override the class Mage_Paypal_Block_Standard_Redirect into something like this:

protected function _toHtml()
{
    $standard = Mage::getModel('paypal/standard');

    //...

    foreach ($standard->getStandardCheckoutFormFields() as $field=>$value) {
        if ($field == 'REASON_CODE') {
            $myvalue = Mage::getSingleton('customer/session')->getCustomer()->getMyvalue();
            $value .= $myvalue;
        }
        $form->addField($field, 'hidden', array('name'=>$field, 'value'=>$value));
    }

    //...

    return $html;
}

I have added a condition in the foreach to edit the reason with your special customer value.

I don't know what is the code for the reason you speak about, if you don't as well you can first log that in the foreach:

Mage::log($field);
Mage::log($value);

Then don't forget to edit 'REASON_CODE' and getCustomer()->getMyvalue() in my example.
