By default, the `pageDetail` tag will retrieve data for which single page?

In the powerful function system of AnQi CMS, flexibly using various tags is the key to improving efficiency for website operators and template developers. Today, we will delve into a tag that is indispensable for building static content pages -pageDetailand it focuses on itWhat single page of data will be obtained by default?This core issue.

ExplorepageDetail: How does it intelligently retrieve data?

As an experienced website operation expert, I know that every tag behind it contains the wisdom of system design.pageDetailTags, as the name implies, are specifically used for obtainingSingle PageDetails of the data. A single page usually refers to those pages with fixed and independent content, such as "About Us", "Contact Information", "Privacy Policy", and so on.

Then, by default,pageDetailWhich single page's data will the tag actually retrieve? The answer is actually very intuitive and smart:In the absence of any additional parameters specified,pageDetailThe tag automatically retrieves the data of the single page being accessed.

This is like when you are browsing a website and click on the 'About Us' navigation bar, after the page jumps, all the content you see naturally belongs to the 'About Us' single page. Anqi CMS'spageDetailThe label is designed this way. It intelligently identifies the corresponding single page based on the current page's URL path, and loads all related data to be used in the template.

For example, when you visit the URL is你的域名/about-us.html(or any URL configured as a single page) in the template file (such aspage/detail.htmlorpage/about-us.htmlIn it, you do not need to provide any ID or alias, just use the following code to get the title of the single page "About Us":

<div>单页标题：{% pageDetail with name="Title" %}</div>

The system will automatically parse the current page and return the corresponding title.This design greatly simplifies the writing of templates, allowing you to focus more on content presentation rather than cumbersome data association.

Beyond Default: Accurately locate specific single page data

Although the default behavior is very convenient, in some special scenarios, you may need to call data from specific single-page templates on non-single-page detail pages, or dynamically retrieve information from a single page through programming. At this time,pageDetailTags also provide powerful flexibility:

1. Specify through page ID(idparameter)If you know the unique numeric ID of a single page in the Anqi CMS system, you can useidParameters to specify the data to be retrieved. For example, to get the content of10: single page content

   <div>特定单页内容：{% pageDetail with name="Content" id="10" %}</div>
   

2. by single page URL alias(tokenparameter)In the Anqi CMS backend, you can set a custom URL for each page, also known as a URL alias or token.This is a user-friendly and easy-to-remember string, such as "about-us", "contact-us", and so on. It is usedtokenThe parameter can be retrieved more readably. For example, to get the link with aliasprivacy-policySingle page link:

   <div>隐私政策链接：{% pageDetail with name="Link" token="privacy-policy" %}</div>
   

3. Data call in multi-site environment(siteIdparameter):For a security CMS system deployed across multiple sites, if you need to call data from a specific single-page across sites, you can usesiteIdParameters are used to specify the target site. This is usually used in large enterprises or multi-brand management scenarios. For example, to get the site ID of2of a single page title:

   <div>其他站点单页标题：{% pageDetail with name="Title" id="5" siteId="2" %}</div>
