When operating a website, we often add some URLs to articles, product descriptions, or single-page content, which may be recommended external resources or references to other content within the site.But if these URLs are displayed only in plain text, users will have to copy and paste to access them, which is inconvenient and affects the reading experience.

AnqiCMS fully considered this point, providing us with a very convenient way to automatically convert plain text URLs in the content into clickable links, greatly enhancing the convenience of user browsing and the professionalism of the website.

Make the URLs in the content automatically 'alive':urlizeFilter

The template engine provided by AnqiCMS (which draws on the syntax style of Django) has a very practical tool calledurlizeFilter. Its main function is to intelligently identify URL strings (includinghttp:///https://with prefixes, evenwww.with prefixes) and automatically wrap them into<a>The label can be turned into a clickable link.

The method of use is very simple, you just need to add it after the text variable you need to process|urlizeYou can. For example, if the content of your article is stored in{{ archive.Content }}In this variable, you can handle it like this:

<div>
    {{ archive.Content|urlize|safe }}
</div>

Pay special attention here|safeThis filter. AnqiCMS for website security, the default is to escape the output content of the template to prevent potential XSS attacks. This means that ifurlizeThe filter converts the URL to HTML format.<a>After the tag, you directly output it, and the browser will display it as plain text instead of a real link. Add|safeTell the template engine that this content is safe HTML that can be rendered directly, so the link can be displayed and clicked normally.

By default,urlizeThe filter will also automatically add to the generated link.rel="nofollow"property.This is very helpful for the SEO strategy of external links, it tells search engines not to pass 'weight' to these links, which helps you better control the flow of external links on your website.

Handle long URLs:urlizetruncFilter

Sometimes, the URLs that appear in articles may be very long. Displaying them directly can make the page look cluttered and affect the overall aesthetics. At this time,urlizetruncThe filter comes into play. It isurlizeBased on that, it adds the feature of truncating link display text, allowing you to specify the maximum length of the link text.

urlizetruncthe way of use isurlizeSimilar, but an additional numeric parameter needs to be passed in to indicate the maximum display length of the link text. The part exceeding this length will be replaced with....

<div>
    {{ archive.Content|urlizetrunc:50|safe }} {# 将网址显示文本截断为50个字符，多余部分显示... #}
</div>

This is a long URL, even if it is included in the original text, the link text displayed on the final page will be neat, and it will still be able to jump to the full original URL when clicked.

Content assistance: Markdown editor

In addition to applying filters directly in the template, if you are accustomed to using Markdown format when writing content in the background, AnqiCMS's Markdown editor can also automatically help you process URLs.
