Intelligent processing of AnQi CMS pagination links

In AnQi CMS,paginationThe tag is used to automatically generate all the links required for pagination, such as home page, previous page, next page, and specific page number links. These links usually contain URL parameters, such as?page=2or may contain during the search?q=关键词&page=3such parameters.

It will automatically ensure that special characters in the links (such as spaces are converted to%20or,&symbols are converted to&so that it is properly handled in HTML, avoiding URL access errors and potential XSS attack risks.

The core of this question lies in the URL generation mechanism within the AnQi CMS.When the system builds pagination links, it identifies and encodes the query parameters in the URL.For example, if your search keyword is 'AnQi CMS', when generating pagination links, the system will automatically encode spaces as%20Ensure that the backend server can correctly parse this keyword. At the same time, in order to safely embed this complete URL into HTML's<a>label'shrefIn the attribute, the system will also perform the necessary HTML entity escaping to prevent the link itself from being mistakenly parsed as HTML code.

This means,paginationTag provided.LinkA field that outputs a 'ready-to-use' URL. It is already a complete, encoded string and suitable for direct use on a webpage.This design greatly simplifies the template development process, allowing you to focus more on content presentation rather than the technical details at the bottom.

When may manual escaping be required?

Although the Anqi CMS'spaginationThe tag performs well in generating links, but in certain specific and more advanced scenarios, you may still need to manually intervene in escaping:

1. Manually concatenate URLs with dynamic parameters:If you choose not to depend entirelypaginationlabel'sLinkOutput, rather than manually constructing a URL that includes user input or other dynamic variables, you need to encode these dynamic parameters yourself. For example, if you are to construct a search link where the search term is entered by the user in a form, you should use|urlencodeThe filter processes, such as{{user_input_keyword|urlencode}}.

2. paginationlabel'sprefixAdvanced usage of parameters: paginationThe tag supports oneprefixThe parameter allows you to customize the URL pattern. Although this parameter is mainly used to define the fixed path pattern before the page number (such asprefix="/my-custom-path?filter=all&page={page}")，But if you try to inject dynamic, unprocessed user input or other complex variables directly into thisprefixIn a string, those dynamic parts may need to be URL-encoded in advance. However, for regular pagination needs, it is usually not necessary to touch this layer.
