我是Magento的新手，我需要在Magento中创建一个自定义模块。 我尝试了以下代码但没有成功。 那有什么解决方案吗？请提供给我并分享一些书籍链接和Youtube链接。

代码文件为 应用程序/代码/本地
-Baobaz
-Arithmetic
它包含块，控制器等，Model。 在controllers文件夹中有一个名为的控制器文件 IntegerController.php和这里的代码：

<?php
class Baobaz_Arithmetic_IntegerController extends Mage_Core_Controller_Front_Action
{
    public function multiplyAction(){
         $this->loadLayout();
        $this->renderLayout();
    }
}

配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<config>
    <modules>
        <baobaz_arithmetic>
            <version>0.0.1</version>
        </baobaz_arithmetic>
    </modules>
   <frontend>
        <routers>
            <arithmetic>
                <use>standard</use>
                <args>
                    <module>Baobaz_Arithmetic</module>
                    <frontName>arithmetic</frontName>
                </args>
            </arithmetic>
        </routers>
      <layout>
            <updates>
                <arithmetic>
                    <file>arithmetic.xml</file>
                </arithmetic>
            </updates>
        </layout>  
    </frontend>
   <global>
    <blocks>
      <arithmetic>
        <class>Baobaz_arithmetic_Block</class>
      </arithmetic>
    </blocks>
    <models>
      <arithmetic>
        <class>Baobaz_arithmetic_Model</class>
      </arithmetic>
    </models>
  </global>
 </config>

Model/Arithmetic.php代码：

<?php

class Baobaz_Arithmetic_Model_Arithmetic extends Mage_Core_Model_Abstract {
  public function getRecentProducts() {
    $products = Mage::getModel("catalog/product")
                -­>getCollection()
                ­->addAttributeToSelect('*')
                ­->setOrder('entity_id', 'DESC')
                ­->setPageSize(5);
    return $products;
  }
}

Block/Arithmetic.php代码：

<?php

class Baobaz_Arithmetic_Block_Arithmetic extends Mage_Core_Block_Template {
  public function getRecentProducts() {
    // call model to fetch data
    $arr_products = array();

    $products = Mage::getModel('arithmetic/arithmetic')->getRecentProducts();

    foreach ($products as $product) {
      $arr_products[] = array(
        'id' => $product-­>getId(),
        'name' => $product­->getName(),
        'url' => $product­->getProductUrl(),
      );
    }

   return $arr_products;
  }
}

app/design/frontend/default/default/layout/arithmetic.xml：

<?xml version="1.0" encoding="UTF-8"?>
<layout version="0.1.0">
    <arithmetic_integer_multiply>
        <reference name="root">
            <action method="setTemplate">
                <template>page/1column.phtml</template>
            </action>
        </reference>
        <reference name="content">
            <block type="arithmetic/arithmetic" name="arithmetic/arithmetic" template="arithmetic/integer/multiply.phtml"></block>
        </reference>
    </arithmetic_integer_multiply>
</layout>

arithmetic/integer/multiply.phtml代码：

<?php

$products = $this­->getRecentProducts();
?>
<div id="product_list">
  <h1>Recent Products</h1>
  <?php if (is_array($products) && count($products)) { ?>
    <?php foreach($products as $product) { ?>
      <div>
        <a href="<?php echo $product['url'] ?>"><?php echo $product['name'] ?></a>
      </div>
    <?php } ?>
  <?php } ?>
</div>

但我收到以下错误：

答案 0 :(得分：0)

当我将上述行（...第3行的... multiply.phtml）复制并粘贴到我的编辑器中时，它会显示＆＃34; $ this＆＃34;？后面有一个特殊字符。尝试删除该字符。

products = $this­[here]­->getRecentProducts();
