Question

此代码（1）的目的是以网格形式在Magento商店中显示子类别。类别图像的大小在代码本身中定义，而分隔和宽度在styles.css中。

如果我正常使用代码，我会获得所有已启用的子类别（IsActive为true）。请参阅此“正在进行的工作”链接：http://www.aldetal.biz/index.php/vabaro/fitness/nutricion.html

我更喜欢显示已启用的子类别，并在其他地方标记为“显示有价值”。这样我就可以在登录页面中以网格形式显示多少个子类别，从菜单中显示的子类别数量。为避免触及数据库，我将使用Meta Keywords字段将字符串showgrid添加为“关键字”标志。

出于某种原因，Tim提出了优秀的IF。

（1）最初由Jake Rutter撰写：http://www.onerutter.com/web/magento-custom-category-images-listing-block-tutorial.html并由我调整

我有以下构造的代码来显示Magento前端的子类别。子类别在启用时显示（“IsActive”为真）。

  if($_categories->count()):
 foreach ($_categories as $_category):
        if($_category->getIsActive()):
               a whole bunch of stuff if true
            else
               other stuff if not true

我想在不弄乱数据库的情况下添加另一个条件，因此我正在使用Meta关键字字段（因为Google正式忽略它，并且无论如何都不会有任何伤害。）

如果类别已启用（IsActive）并且该字段中的第一个字符串是“showgrid”，则IF为true，并且会发生一大堆事情。

但小心：元关键字字段可能为空，因此我需要对其进行测试以及确定其内容。如果未启用该类别（IsActive为false）或Meta关键字为空或Meta关键字不以showgrid开头，则其他内容发生

Answer 1

比元标记字段更好的解决方案是向类别添加新属性。

在app / code / local / [YourCompany] / Category

中创建目录

在app / code / local / [YourCompany] /Category/etc/config.xml

中创建config.xml文件

<?xml version="1.0"?>
<config>
    <modules>
         <YourCompany_Category>
             <version>0.1.0</version>
         </YourCompany_Category>
    </modules>
    <global>
        <resources>
            <category_setup>
                <setup>
                    <class>Mage_Eav_Model_Entity_Setup</class>
                    <module>YourCompany_Category</module>
                </setup>
                <connection>
                    <use>default_setup</use>
                </connection>
            </category_setup>
        </resources>
    </global>
</config>

接下来在app / etc / modules / YourCompany_Category.xml

中创建模块配置

<?xml version="1.0"?>
<config>
    <modules>
         <YourCompany_Category>
             <active>true</active>
             <codePool>local</codePool>
         </YourCompany_Category>
    </modules>
</config>

接下来，我们在app / code / local / YourCompany / Category / sql / category_setup / mysql4-install-0.1.0.php中创建安装程序

<?php
$installer = $this;
$installer->startSetup();
$installer->addAttribute('catalog_category','category_show_grid', array(
    'type'              => 'int',
    'group'             => 'General Information',
    'backend'           => '',
    'frontend'          => '',
    'label'             => 'Show in grid',
    'input'             => 'select',
    'class'             => '',
    'source'            => 'eav/entity_attribute_source_boolean',
    'global'            => Mage_Catalog_Model_Resource_Eav_Attribute::SCOPE_STORE,
    'visible'           => 1,
    'required'          => 0,
    'user_defined'      => 1,
    'default_value'     => 1,
    'searchable'        => false,
    'comparable'        => false,
    'visible_on_front'  => false,
    'unique'            => false
));
$installer->endSetup();

然后您应该可以在代码中调用它

if ($_category->getIsActive() && $_category->getCategoryShowGrid()) {
}

在Magento - Edit01中将Meta关键字条件添加到IF

代码
