我想在 bundle 项目的默认标题下方添加新文本列。
创建新的捆绑产品时，我需要添加额外的字段
我想要在默认标题下方添加新文本字段以添加说明。
请帮忙。任何帮助将不胜感激。
最佳答案
为了添加新的description field在每个 bundle option ，您需要创建一个模块。简而言之，您的模块将执行以下功能。
创建一个新表来保存我们的
description field用于捆绑选项。当产品保存时，它将更新我们的表格并进行必要的更改。
考虑到这一点，让我们创建我们的模块。让我们的模块为Programmerrkt_Customfieldinbundle
位置:app/code/local/Programmerrkt/Customfieldinbundle/etc/config.xml
<config>
<modules>
<Programmerrkt_Customfieldinbundle>
<version>0.1.1</version>

<programmerrkt_customfieldinbundle>
<class>Programmerrkt_Customfieldinbundle_Block</class>
</programmerrkt_customfieldinbundle>
</blocks>
</global>
</config>
我们的配置文件包含有关自定义表的详细信息 catalog_product_bundle_option_description我们将在其中存储 bundle 描述。它还定义了一个观察者，当触发时，会将更改保存到我们的自定义表中。
位置:app/etc/modules/Programmerrkt_Customfieldinbundle.xml
<config>
<modules>
<Programmerrkt_Customfieldinbundle>
<active>true</active>
<codePool>local</codePool>
</Programmerrkt_Customfieldinbundle>
</modules>
</config>
现在我们需要在管理端显示我们的描述字段。为此，我们需要编辑一个 block 来呈现 bundle 选项。该 block 是 app/code/core/Mage/Bundle/Block/Adminhtml/Catalog/Product/Edit/Tab/Bundle/Option.php 。我们需要更改此文件中的两个方法。 **仅显示主要部分
<?php

/**

public function __construct()
{
$this->setTemplate('programmerrkt/customfieldinbundle/bundle/product/edit/bundle/option.phtml');
//$this->setTemplate('bundle/product/edit/bundle/option.phtml');
$this->setCanReadPrice(true);
$this->setCanEditPrice(true);
}
------
/**

public function getOptions()
{
if (!$this->_options) {
$customCollection = Mage::getModel('customfieldinbundle/optiondescription')->getCollection();
$store_id = $this->getProduct()->getData('store_id');
//sets default values of description module
$empty = FALSE;
if(count($customCollection)){
$description_id = (int)(count($customCollection)+1);
}
else{
$empty = TRUE;
$description_id = 1;
}
$description_content = "";
$this->getProduct()->getTypeInstance(true)->setStoreFilter($this->getProduct()->getStoreId(),
$this->getProduct());
$optionCollection = $this->getProduct()->getTypeInstance(true)->getOptionsCollection($this->getProduct());
$selectionCollection = $this->getProduct()->getTypeInstance(true)->getSelectionsCollection(
$this->getProduct()->getTypeInstance(true)->getOptionsIds($this->getProduct()),
$this->getProduct()
);
$this->_options = $optionCollection->appendSelections($selectionCollection);
foreach ($this->_options as $option) {
//gets each option's id
$option_id = $option->getData('option_id');
//loop through module collection
if($empty === FALSE){
foreach($customCollection as $description){
//finds the entry corresponds to option id, if exist
if($description['option_id']==$option_id && $description['store_id']==$store_id){
$description_id = (int)$description['description_id'];
$description_content = $description['description'];
break;
}
}
//adds our new datas to option
$option->addData(array('desc_id'=> $description_id, 'description' => $description_content, 'desc_new'=> 'no'));
}
else {
$description_id = (int)$description['description_id'];
$description_content = $description['description'];
//adds our new datas to option
$option->addData(array('desc_id'=> $description_id, 'description' => $description_content,'desc_new'=> 'yes'));
$description_id++;
}
}
if ($this->getCanReadPrice() === false) {
foreach ($this->_options as $option) {
if ($option->getSelections()) {
foreach ($option->getSelections() as $selection) {
$selection->setCanReadPrice($this->getCanReadPrice());
$selection->setCanEditPrice($this->getCanEditPrice());
}
}
}
}
}
return $this->_options;
}
------
这些方法是
-
__construct()
此方法用于定义选项内容渲染的自定义模板。使用这个我们可以避免核心模板编辑。
getOption() 此方法用于将我们模块的数据包含到现有选项中。通过这种方法，magento 将显示已创建的选项的设置描述。
现在是我们的模板文件。 **仅显示主要部分

我们所做的是，我们在标题字段下方添加了一个文本区域。
现在是最重要的文件。我们的观察者。这对我们的模块起到了作用。它用于通过检查不同的标准来保存我们的数据。

注意:我只描述了我们模块的重要文件。我想你们都知道如何在 Magento 中设置基本模块。
就是这样。你已经准备好出发了。清除缓存并加载捆绑产品。您可以在 bundle 选项的标题字段下方看到一个文本区域。
如有任何疑问，请随时询问。
关于Magento 在捆绑项目中添加另一个新字段，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/24097689/
