In the daily use of the AnQiCMS content management system, template filters are an important tool for us to process and display data. Among them,urlizeThe filter is often used for its convenience to automatically convert URLs and email addresses in text content into clickable hyperlinks, and it automatically addsrel="nofollow"Attribute, this is very useful for processing user-generated content (UGC) or automatically recognizing links in the article body.

urlizeThe role and common usage of filters

According to the document description of AnQiCMS,urlizeThe core function of the filter is to intelligently recognize link patterns in text. It can recognize complete URLs containing protocols such ashttp:///https://), withwww.The domain prefix, as well as the bare domain without any prefix (e.g.,kandaoni.com). It can also convert email addresses (such as[email protected]) intomailto:Links. These automatic conversions greatly simplify the content editing and publishing process, especially when quickly processing large amounts of unstructured text.

For example, when using templates.urlizeWhen filtering, if the text contains:

AfterurlizeThey will all be automatically added with<a>tags, turning them into clickable links and withrel="nofollow".

urlizeSupport for IP address format URLs in the filter

We understand that users may have questions. In certain specific scenarios, such as internal network access, test environments, or integration with special services, URLs in the form of IP addresses may occur, for example,http://192.168.1.1or192.168.1.1Then,.urlizeCan the filter recognize and convert such links?

By carefully reviewing the AnQiCMS documentation, we can findurlizeThe example of the filter focuses on URLs in traditional domain name format, and does not explicitly mention whether it supports recognition and conversion of URLs in IP address format. From its recognitionhttp:///https://Prefix of the protocol as wellwww.From the perspective of the prefix of the domain, for IP addresses that include the full protocol, such ashttp://192.168.1.1Sincehttp://The explicit indication of the protocol, itIt is possiblewill be recognized as a link. However, for bare IP addresses without a protocol prefix, such as192.168.1.1, it does not conform to the common domain structure pattern (missingwww.or top-level domain suffix),urlizeFilter很可能无法【en】cannot probably将其识别为可点击的链接。【en】Identify it as a clickable link.

稳妥的建议与**实践【en】Safe suggestions and **practice

Given that the document does not explicitly state support for IP address formatted URLs, for safety, we do not recommend relying on them entirely.urlizeThe filter automatically converts links in IP address format, especially for those critical links that must ensure accessibility.

In content operation, if you need to display a URL in IP address format and ensure that it is clickable, the most reliable method is to directly use standard HTML<a>Label manually create links. For example:请访问 <a href="http://192.168.1.1" rel="nofollow">http://192.168.1.1</a> 进行配置。This ensures the accuracy and stability of the link, avoiding the problem of link failure due to the difference in recognition rules of the filter.

urlizeThe filter is designed for convenience, mainly used to process user input or extract common public links from unstructured text.For links that are structured, critical, or in a special format, manually writing HTML is still** a practice, which can provide more precise control and stronger stability.
