Magento-创建新模块时的空白页 [英] Magento - Blank page when creating new module
问题描述
我正在使用Mangeto 1.9.1，并且试图创建一个模块，以使价格从总价中获得50％的折扣.
I'm using Mangeto 1.9.1 and I'm trying to create a module for 50% discount from the grandtotal price.
我已经对该模块做了一些操作，但是当我尝试打开 http://mymagento时. com/checkout/cart/我的主菜单下有空白页.我的购物车项目和总计应在的空白页.
I've made some things to the module but when I try to open my http://mymagento.com/checkout/cart/ I've got blank page bellow my main menu. Blank page where my cart items and total should be.

我通过以下答案制作了此模块: Magento -创建自定义模块的问题
I've made this module by this answer: Magento - Issue with creating a custom Module
这就是我所做的:

在应用程序/代码/本地/VivasIndustries/PercentPayment/模型/Newordertotalobserver.php中:
In In app/code/local/VivasIndustries/PercentPayment/Model/Newordertotalobserver.php:
<?php

{
public function saveDiscountTotal(Varien_Event_Observer $observer)

return $this;
}
}
在app/code/local/VivasIndustries/PercentPayment/Model/Order/Invoice/Total/Discount.php中:
In app/code/local/VivasIndustries/PercentPayment/Model/Order/Invoice/Total/Discount.php:
<?php
class VivasIndustries_PercentPayment_Model_Order_Invoice_Total_Discount

$invoice->setBaseGrandTotal($invoice->getBaseGrandTotal()+$orderDiscountTotal);
}
return $this;
}
}
在应用程序/代码/本地/VivasIndustries/PercentPayment/模型/报价/地址/总计/Discount.php中:
In app/code/local/VivasIndustries/PercentPayment/Model/Quote/Address/Total/Discount.php:
<?php
class VivasIndustries_PercentPayment_Model_Quote_Address_Total_Discount extends Mage_Sales_Model_Quote_Address_Total_Abstract
{
public function __construct()
{
$this -> setCode('discount_total');
}
/**
* Collect totals information about discount
*
* @param Mage_Sales_Model_Quote_Address $address
* @return Mage_Sales_Model_Quote_Address_Total_Shipping
*/
public function collect(Mage_Sales_Model_Quote_Address $address)
{
parent :: collect($address);
$items = $this->_getAddressItems($address);
if (!count($items)) {
return $this;
}
$quote= $address->getQuote();
//amount definition
$discountAmount = 50;
//amount definition
$discountAmount = $quote -> getStore() -> roundPrice($discountAmount);
$this -> _setAmount($discountAmount) -> _setBaseAmount($discountAmount);
$address->setData('discount_total',$discountAmount);
return $this;
}
/**

'value' => $amount

}
return $this;
}
/**

public function getLabel()
{
return Mage :: helper('modulename') -> __('Discount');
}
}
在app/code/local/VivasIndustries/PercentPayment/sql/percentpaymentatribute_setup/mysql4-install-0.1.0.php中:
And in app/code/local/VivasIndustries/PercentPayment/sql/percentpaymentatribute_setup/mysql4-install-0.1.0.php:
<?php
$installer = $this;
$installer->startSetup();
$installer->addAttribute("quote_address", "discount_total", array("type"=>"varchar"));
$installer->addAttribute("order", "discount_total", array("type"=>"varchar"));
$installer->endSetup();
最后我做了这个:
在app/etc/modules/VivasIndustries_PercentPayment.xml中:
In app/etc/modules/VivasIndustries_PercentPayment.xml:
<?xml version="1.0"?>
<config>
<modules>
<VivasIndustries_PercentPayment>
<active>true</active>
<codePool>local</codePool>
<version>0.1.0</version>
</VivasIndustries_PercentPayment>
</modules>
</config>
这就是我所做的全部，我得到的空白页没有任何错误.
And that's all what I've done and I get this blank page with no error.
能帮我找到问题并解决吗?
Can you please help me find the problem and fix it?
*编辑
我什么时候删除:
public function getLabel()
{
return Mage :: helper('modulename') -> __('Discount');
}
该页面是固定的，仅显示折扣值，而没有折扣"说明.
The page is fixed and it is showing only the discount Value without the "Discount" description.
提前谢谢！
