問題描述

我最近開始在客戶的網上商店中使用 Magento，但仍然需要掌握它的系統.

I've recently started using Magento for a client's webshop, and still need to get to grips with its systems.

網上商店應該有多個鏈接，并且還可以從公司網站所在的另一個域中獲取信息.我不想對域名或 URL 進行硬編碼，而是在某個地方定義它并在整個網上商店的 phtml 模板中使用該值.當我們在開發 URL、暫存 URL 和生產 URL 之間移動站點時，這樣可以輕松調整它.

The webshop should have several links to and also grab info from another domain, where the corporate website is located. I would prefer not to hardcode the domain name or URL but instead define it at some place and use that value in the phtml templates throughout the webshop. This makes it easy to adjust it when we move the site between dev, staging and production URL's.

任何人都可以建議 Magento 這樣做嗎?最好我們可以在后端的商店配置 GUI 中添加一個字段，類似于設置 {{base_url}} 的方式.還是我的想法錯了?

Can anyone suggest the Magento way of doing this? Preferably we could add a field to the Store's Config GUI in the backend, similar to the way the {{base_url}} is set. Or maybe I'm thinking the wrong way?

推薦答案

Magento 為自定義配置值提供(相對)簡單的支持.我發現實現此目的的最佳方法是創建一個單獨的 magento 模塊，其中包含所有自定義配置值.

Magento offers (relatively) easy support for custom configuration values. The best way I've found to accomplish this is to create a single magento module that holds all your custom configuration values.

像 Magento 一樣，有很多步驟，任何一個錯誤都可能絆倒你(或我！).

Like anything Magento, there are a lot of steps, and any one being wrong could trip you (or me!) up.

首先，您需要設置一個 magento 模塊來保存所有自定義配置值.創建一個 magento 模塊涉及

First, you'll want to setup a magento module to hold all your custom configuration values. Creating a magento module involves

1. 在 app/etc/modules 中創建一個 xml 文件
2. 在 app/code/local/Companyname 中創建文件夾結構

Companyname 是一個唯一的字符串，用作命名空間，大多數 magento 教程建議您在此處使用您的公司名稱.出于本教程的目的，我將使用Stackoverflow".無論您在何處看到字符串 Stackoverflow，都將其替換為您自己的唯一字符串.

Companyname is a unique string that serves as a namespace, and most magento tutorials recommend you use your company name here. For the purposes of this tutorial, I'll use "Stackoverflow". Wherever you see the string Stackoverflow, replace it with your own unique string.

因此，對于第 1 步，在 app/etc/modules 中創建一個名為Stackoverflow_Customconfig.xml"的文件，并將以下內容放入

So, for step 1, create a file at app/etc/modules named "Stackoverflow_Customconfig.xml", and place the following inside

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

隨機 Magento 提示:Magento 系統的某些部分認為空格很重要，因此最好不要在屬性值中包含空格(true</active> vs. true <;/活動>

Random Magento Tip: There are parts of the magento system that consider whitespace significant, so it's always best to include no whitespace with your attribute values (<active>true</active> vs. <active> true </active>

接下來，創建以下文件夾

Next, create the following folder

mkdir app/code/local/Stackoverflow/Customconfig
mkdir app/code/local/Stackoverflow/Customconfig/etc

并在

app/code/local/Stackoverflow/Customconfig/etc/config.xml

有以下內容

<?xml version="1.0"?>
<config>
    <modules>
        <Stackoverflow_Customconfig>
            <version>0.1.0</version>
        </Stackoverflow_Customconfig>
    </modules>
</config>

恭喜，您剛剛設置了一個新的 Magento 模塊.如果您清除 magento 緩存并轉到

Congratulations, you've just setup a new Magento Module. If you clear your magento cache and go to

System -> Configuration -> Advanced -> Disable Modules Output

您應該會看到列出的模塊.

you should see your module listed.

接下來，我們將添加一個 system.xml 文件.此文件用于向 magento 添加自定義配置值，您可以在 magento 請求周期中的任何位置獲取該值.在

Next, we're going to add a system.xml file. This file is used to add a custom configuration value to magento, which you'll be able to grab anywhere you want during the magento request cycle. Add a file at

app/code/local/Stackoverflow/Customconfig/etc/system.xml

包含以下內容

<config>
    <sections>
        <design>
            <groups>
                <my_or_their_group translate="label">
                    <label>A grouping of config values.  Make your own, or us an existing group.</label>
                    <frontend_type>text</frontend_type>
                    <sort_order>50</sort_order>
                    <show_in_default>1</show_in_default>
                    <show_in_website>0</show_in_website>
                    <show_in_store>0</show_in_store>
                    <fields>
                        <my_config translate="label">
                            <label>This will be my config's label</label>
                            <frontend_type>text</frontend_type>
                            <sort_order>50</sort_order>
                            <show_in_default>1</show_in_default>
                            <show_in_website>0</show_in_website>
                            <show_in_store>0</show_in_store>
                        </my_config>
                    </fields>
                </my_or_their_group>
            </groups>
        </design>
    </sections>
</config>   

是您的配置將在其中顯示的部分的名稱.常規、網頁、設計、貨幣設置等".總的來說，這將是標題的小寫版本，即General"變為general"，Design"變為design".如果您不確定這個外部標簽應該是什么，請搜索核心 magento 模塊.即，對貨幣設置"的 grepping 顯示在

<design> is the name of the section your config will be displayed in. "General, Web, Design, Currency Setup, etc." By and large, this will be a lower-case version of the title, i.e. "General" becomes "general", "Design" becomes "design". If you're not sure what this outer tag should be, search through the core magento modules. i.e., grepping for "Currency Setup" reveals a mention in

app/code/core/Mage/Directory/etc/system.xml
<currency translate="label" module="directory">
    <label>Currency Setup</label>

所以你會使用標簽<currency/<，而不是更直觀的<currency_setup/>

So you'd use the tag <currency /<, and not the more intuitive <currency_setup />

是您的配??置變量將在其中顯示的組的名稱.組是包含配置字段的 Ajax 下拉列表.例如，常規"部分有一個國家選項"組和一個本地選項"組.如果您不確定如何在現有組中放置值，請再次檢查現有核心模塊.

<my_or_their_group translate="label"> is the name of the group your config variable will show up in. Groups are the Ajax drop downs that contain config fields. For example, the General section has a "Country options" group and a Local options" group. Again, check existing core modules if you're unsure how to place a value in an existing group.

您還會注意到這里有一個 translate 屬性，以及相應的標簽標記.這允許您在 HTML 界面中使用您想要的任何字符串作為組標題，但在內部將該名稱保留為有效的 XML 標記名稱.我們的標簽被命名為

You'll also notice a translate attribute here, along with a corresponding label tag. This allows you to use any string you want in the HTML interface as a group title, but internally keep the name a valid XML tag name. Our tag is named

<my_or_their_group />

但在界面中，群組會有標題

but in the interface, the group will have the title

一組配置值.建立您自己的或我們現有的群組.

A grouping of config values. Make your own, or us an existing group.

最后，<my_config translate="label">是 yoru conifg 值的名稱.再次注意translate 屬性.與上述相同的規則適用.

Finally, <my_config translate="label"> is the name of yoru conifg value. Again, notice the translate attribute. The same rules as above apply.

需要其他 xml 結構，并且(主要)用于控制將用于您的配置的 HTML 輸入類型.如果需要特定的界面元素，請在核心模塊中找到示例并復制 XML 結構.

The other xml structure is needed, and is (mostly) used to control what kind of HTML inputs will be used for your config. If you want a particular interface element, find an example in the core module and copy the XML structure.

這將允許您在 Magento GUI 界面中設置和查找配置值.您可以使用全局 Mage 對象的靜態 getStoreConfig 方法并指定配置值的 URI 來檢索您的值.URI 是使用配置的部分/組/名稱創建的.

This will allow you to set and lookup config values in the Magento GUI interface. You can retrieve your values using the static getStoreConfig method of the global Mage object and specifying the URI of your config value. The URI is created using the section/group/name of your config.

Mage::getStoreConfig('design/my_or_their_group/my_config');
