Magento-创建自定义模块的问题 [英] Magento - Issue with creating a custom Module
问题描述
我正在使用Magento 1.9.1，并且试图创建一个模块，该模块可以提供总计50％的折扣.
I'm using Magento 1.9.1 and i'm trying to create a module which is giving a 50% discount from the grand total.
这是我的代码:
/app/code/local/VivasIndustries/PercentPayment/etc/config.xml:
/app/code/local/VivasIndustries/PercentPayment/etc/config.xml :
<?xml version="1.0"?>
<config>
<modules>
<VivasIndustries_PercentPayment>
<version>0.1.0</version>
</VivasIndustries_PercentPayment>
</modules>
<global>
<sales>
<quote>
<totals>
<discount>
<class>VivasIndustries_PercentPayment_Model_Discount</class>
<after>subtotal</after>
</discount>
</totals>
</quote>
<order_invoice>
<totals>
<discount>
<class>VivasIndustries_PercentPayment_Model_Invoice</class>
<after>subtotal</after>
</discount>
</totals>
</order_invoice>
<order_creditmemo>
<totals>
<discount>
<class>VivasIndustries_PercentPayment_Model_Creditmemo</class>
<after>subtotal</after>
</discount>
</totals>
</order_creditmemo>
</sales>
</global>
</config>
/app/code/local/VivasIndustries/PercentPayment/controllers/IndexController.php:
/app/code/local/VivasIndustries/PercentPayment/controllers/IndexController.php :
<?PHP
class VivasIndustries_PercentPayment_Model_Discount extends Mage_Sales_Model_Quote_Address_Total_Abstract {
public function collect(Mage_Sales_Model_Quote_Address $address) {
if ($address->getData('address_type') == 'billing')
return $this;
$discount = 50; //your discount percent
$grandTotal = $address->getGrandTotal();
$baseGrandTotal = $address->getBaseGrandTotal();
$totals = array_sum($address->getAllTotalAmounts());
$baseTotals = array_sum($address->getAllBaseTotalAmounts());
$address->setFeeAmount(-$totals * $discount / 100);
$address->setBaseFeeAmount(-$baseTotals * $discount / 100);
$address->setGrandTotal($grandTotal + $address->getFeeAmount());
$address->setBaseGrandTotal($baseGrandTotal + $address->getBaseFeeAmount());
return $this;
}
public function fetch(Mage_Sales_Model_Quote_Address $address) {
if ($address->getData('address_type') == 'billing')
return $this;
$amt = $address->getDiscountAmount();
if ($amt != 0) {
$address->addTotal(array(
'code' => 'Discount',
'title' => 'Discount',
'value' => $amt
));
}
return $address;
}
}
?>
/app/etc/modules/VivasIndustries_PercentPayment.xml:
/app/etc/modules/VivasIndustries_PercentPayment.xml :
<?xml version="1.0"?>
<config>
<modules>
<VivasIndustries_PercentPayment>
<active>true</active>
<codePool>local</codePool>
</VivasIndustries_PercentPayment>
</modules>
</config>
这是我为新模块创建的所有文件.我所做的一切.
This are all files which i've created for my new module. All what i've done.
我正在使用此指南: http://magento.ikantam. com/qa/how-add-discount-total-magento
现在，当我尝试打开结帐页面时，出现错误-There has been an error processing your request
Now when i try to open my checkout page i got error - There has been an error processing your request
当我打开error_log时，我可以看到以下内容:
When i open my error_log i can see this thing:
[09-Nov-2014 18:22:35 UTC] CSRF state token does not match one provided.
能帮我解决这个问题，并使新模块按预期工作吗?
Can you please help me fix this problem and make my new Module works like intended ?
提前谢谢！
推荐答案
修改总数始终是困难的部分.除非我在系统中设置了该模块，否则很难在您的代码中找到问题所在.无论如何，我在这里共享了一些代码，用于在结帐过程中修改总计.我尽我所能解释.
Modifying total is always difficult part. And it's hard find out the problem in your code unless I have set up of that module in my system. Anyway here I have shared some codes for modifying total during checkout process. I explained as much I can.
为此，您必须更新很多东西. 报价，地址，订单，Creditmemo，发票，运输，多次运输等.好的，我们开始吧， 首先，我们需要创建名为config.xml的配置文件， config.xml
For this you have to update lot of things. Quote, Address, Order, Creditmemo , Invoice, shipping, multi shipping etc. Okay here we go, First we need to create our configuration file that's called config.xml, config.xml

根据此配置更改其他内容.在此之前，请使用phpmyadmin打开core_resources表进入数据库.并删除您的模块条目(如果有的话).就是这样.
如有任何疑问，请在这里评论.
change other things as per this configuration. before that go to your database using phpmyadmin open core_resources table. and delete your module entry if it is there. that's it.
Please comment here, if you have any doubt.
