add some information to the credit card payment method in Magento

In the system-provided functionality, only < credit card holders >, credit card numbers, expiration dates, CVV, but in actual use, will require more information. Such as: The postal code of the credit card holder, the street address, the state and so on. When brushing a customer's credit card, it is prudent to expect it to be successful only if the information is exactly the same as the information registered on the credit card. So add some extra information. Here's how to add a zip code to the credit card payment information.

Previous job: Add a field to the Sales_flat_quote_payment first, zipcode

Train of thought: need first from Ajax as a clue, find the relevant template files, and then modify the program to achieve zipcode data preservation

1. Find the template used in payment first to Saveshippingmethodaction, obviously, it's _getpaymentmethodshtml's work.

protected function _getpaymentmethodshtml ()
{
$layout = $this->getlayout ();
$update = $layout->getupdate ();
$update->load (' Checkout_onepage_paymentmethod ');
$layout->generatexml ();
$layout->generateblocks ();
$output = $layout->getoutput ();
return $output;
}

2. Under the Layout folder of your current template, find checkout.xml File open, find

<checkout_onepage_paymentmethod>
<remove name= "right"/>
<remove name= "left"/>
<block type= "Checkout/onepage_payment_methods" name= "root" output= "toHtml" "template=" checkout/onepage/payment/ Methods.phtml ">
<action method= "Setmethodformtemplate" ><method>purchaseorder</method><template>payment/ Form/purchaseorder.phtml</template></action>
</block>
</checkout_onepage_paymentmethod>

Found it was using a methods.phtml template.

3. Open methods.phtml, see the following

$html = $this->getchildhtml (' Payment.method. ') $_code)

Obviously, it is going to output the current template directory under payment/save/$_code.phtml (path based on Layout.xml setpaymentformtemplate get)

4. Open $_code.phtml, add a row of zipcode content

<li>
<div class= "Input-box" >
<label for= "<?php echo $_code >_zipcode" ><?php echo $this->__ (' zipcode ')?> <span-class= " Required ">*</span></label><br/>
<input type= "text" title= "<?php Echo $this->__ (' ZipCode ')?>" class= "Required-entry input-text" id= " PHP echo $_code >_zipcode "Name=" Payment[zipcode] "value=" <?php Echo $this->htmlescape ($this-> Getinfodata (' ZipCode '))?> "/>
</div>
</li>

The display section ends here, and the following starts to add code to save the postcode to the database


5. Find the Savepaymentaction method in app/code/core/mage/checkout/controllers/onepagecontroller.php

Public Function savepaymentaction () {
$result = $this->getonepage ()->savepayment ($data);
}

6. Analysis of Savepayment methods

app/code/core/mage/checkout/model/type/onepage.php

$payment = $this->getquote ()->getpayment ();
$payment->importdata ($data);

7. Analysis of ImportData methods

Note: Here we start with AOP, a crosscutting in ImportData, a process that is the payment preparesave process that is designed to encrypt the plaintext information of credit cards.

Public function ImportData (array $data)
{
$data = new Varien_object ($data);
Mage::d ispatchevent (
$this->_eventprefix. ' _import_data_before ',
Array
$this->_eventobject=> $this,
' Input ' => $data,
)
);
$this->setmethod ($data->getmethod ());

$method = $this->getmethodinstance ();
if (! $method->isavailable ($this->getquote ()) {
Mage::throwexception (Mage::helper (' Sales ')->__ (' requested Payment method are not available '));
}
$method->assigndata ($data);
/*
* Validating the payment data
*/
$method->validate ();
return $this;
}


Another important thing is $method->assigndata ($data), which performs the Assigndata method of the specified payment.

For example: The Assigndata way to pay for credit cards is

8. Modify the app/code/core/mage/payment/model/method/cc.php file

Public Function Assigndata ($data)
{
if (!) ( $data instanceof Varien_object)) {
$data = new Varien_object ($data);
}
$info = $this->getinfoinstance ();
$info->setcctype ($data->getcctype ())
->setccowner ($data->getccowner ())
->setcclast4 (substr ($data->getccnumber (),-4))
->setccnumber ($data->getccnumber ())
->setcccid ($data->getcccid ())
->setzipcode ($data->getzipcode ())
->setccexpmonth ($data->getccexpmonth ())
->setccexpyear ($data->getccexpyear ());
return $this;
}
