Business Catalyst:检查Liquid是否在根URL上 [英] Business Catalyst: Check if we are on the root URL with Liquid

问题描述

我想使用Liquid标记来测试正在查看的页面是否是主页(但具体来说是网站的根URL)，例如www.mysite.com/

I would like to use Liquid markup to test if the page that is being viewed is the home page (but specifically the root URL of a website), e.g. www.mysite.com/

我尝试使用{{globals.get}}，因为根据 BC文档，这应该输出...

I attempted to use {{globals.get}}, because according to the BC Documentation, this should output...

当前相对路径和在URL中传递的查询参数.例如，对于URL http://mtica1.businesscatalyst.com/_s1/s2?a=1& ; b = 2 模块是:

The current relative path and the query parameters passed in the URL. For example, for the URL http://mtica1.businesscatalyst.com/_s1/s2?a=1&b=2 the output of the module is:

{
    "ID": "/_s1/s2",
    "a": "1",
    "b": "2"
}

[强调我的]

但是，看来Business Catalyst不能始终如一地处理此Liquid标签.在网站根目录{{globals.get}}的输出{}以及其他系统页面(例如电子商务布局)上，ID被替换为CatalogueID: "xxxxx"，其中xxxxx是目录的ID，而不是当前相对路径" ！

However, it appears that Business Catalyst does not deal with this Liquid tag consistently. On the site root {{globals.get}} outputs {} and on other system pages such as the eCommerce layouts, ID is replaced with CatalogueID: "xxxxx", where xxxxx is the ID of the Catalogue, NOT the "current relative path" at all!

不用说，我无法按预期输出ID: "/"来定位站点根目录.

Needless to say, I was unable to output ID: "/" to target the site root as expected.

如何使用Liquid测试用户是否在根URL上?

推荐答案

我在此答案的开头添加了另一个解决方案，但是将我原来的解决方案留在下面，以便其他人可以看到我所经历的过程.

尽管我对下面详细介绍的解决方案没有任何问题，但是由于空白"在BC中没有记录，所以我希望该解决方案在BC Dev团队进行更新时不会被破坏.

While I have had no issues with the solution detailed below, due to "blank" being undocumented in BC, I would prefer a solution that does't have the potential to be broken if the BC Dev team make updates.

您可以使用以下Liquid标记来检查您是否是站点根目录:

    {module_pageaddress collection="page" template=""}
    {module_siteUrl collection="site" template=""}

    {% assign fullUrl = 'http://' | append: {{site.siteUrl}} | append: '/' -%}

    {% if page.pageUrl == {{fullUrl}} -%}

        // we are on the site root

    {% else -%}

        // we are not on the site root

    {% endif -%}

PREVIOUS SOLUTION

You can test if you are on the site root using the following Liquid markup:

{% if globals.get == blank -%}
    // we are on the root URL - do something
{% else -%}
    // we are not on the root URL
{% endif -%}

此处的关键"信息是关键字空白.

The "key" piece of information here is the keyword blank.

我进行了许多测试，发现唯一的页面(作为{{globals.get}}的结果输出{}的页面)是根URL. (注意:我尚未对此进行详尽的测试-如果您找到另一个输出{}的页面，请发表评论)

I did a number of tests and discovered that the only page that outputs {} as a result of {{globals.get}} is the root URL. (Note: I have not tested this exhaustively - please comment if you find another page that outputs {})

我尝试了{% if globals.get == {} -%}，但这只是针对所有页面，因为所有页面在{}中都有输出.

I tried {% if globals.get == {} -%} but this simply targets all pages because all of them have something output inside {}.

BC文档没有任何内容，但我发现此文档提到它并感到惊讶，惊奇:它有效.

BC Documentation had nothing, but I found this document which mentions it and surprise, surprise: it works.

我们只希望BC Dev团队不要去做一些改变，以免其无法正常工作.

Let's just hope the BC Dev team don't go and change something that stops this from working.
