AnQiCMS Help Document and User Guide
In AnQiCMS (AnQiCMS) daily content operations, we often need to display related keywords on articles or product detail pages.These keywords not only help search engines understand the content of the page, but also guide users to discover more relevant information.In most cases, we will enter these keywords in a text box on the backend, separated by commas, for example: "website operation, SEO optimization, content marketing.
In the world of AnQi CMS templates, flexible data handling is the key to improving website user experience and SEO performance.Sometimes, we need to extract a specific part from a long URL, such as path parameters, product ID, or simply display a part of the URL to keep the page concise.At this time, the `slice` filter is an extremely useful tool that can help us accurately cut any segment of a string or array.
In AnQi CMS template development, we often need to flexibly truncate and display strings or data lists, only showing a part of them.The `slice` filter is designed for this purpose, allowing us to precisely control the length of the content.And the answer to whether the `slice` filter supports negative indices, which is whether it can start cutting from the end, is affirmative, and this feature greatly enhances our flexibility and convenience when dealing with dynamic content templates.
In Anqi CMS template development, the `slice` filter is a commonly used tool for handling strings and arrays.It can help us conveniently extract a part of the content, whether it is several elements of a list or a specified segment of a long text.However, when it comes to cutting Chinese character strings, if you are not familiar with the underlying working principle, you may encounter a common and annoying problem: the cutting result appears as 'half a character' or garbage code.
During the template development process of AnQi CMS, we often need to flexibly handle the data displayed on the page, especially when the data is presented in the form of a list or sequence.Imagine that you are designing a product list page, where you need to select the top 5 most popular products from an array of dozens of products to display at the top of the page; or, you may need to truncate a long string from the content of an article detail page to use as a summary.
AnQiCMS provides rich template filters to help us flexibly handle and display data.Among them, the `length_is` filter is often used to determine whether the length of the variable meets expectations.However, during use, one may encounter a question: What will the system do if we pass non-string or non-numeric data to the `length_is` filter for length comparison?This is not just a technical detail, but also about how we avoid potential errors in template design and ensure the accuracy of data display.
In the daily operation of AnQi CMS, we often need to manage user-generated content, especially user comments, which directly affect the activity and professionalism of the website.Content length control is one of the common requirements, for example, we hope that the comments are not too short to seem perfunctory, nor too long to affect the reading experience.Anqi CMS's flexible template engine provides a variety of powerful filters that can help us easily implement these seemingly complex validation logic.
AnQiCMS template `length` filter: Deep understanding of its length calculation mechanism During the development of AnQiCMS templates, we often need to judge the length of strings, lists (arrays), or key-value pairs (Maps) to control the display logic of content.The `length` filter is designed for this purpose, it helps us get the length information of these data types.However, many users are confused about whether it considers null or `nil` elements when calculating length.

In website content operation, we often need to fine-tune the display form of content, especially for information such as article summaries, which not only affects the first impression of users but also plays an important role in the inclusion of search engines.In AnQiCMS (AnQiCMS) flexible and powerful template system, getting the actual character length of the article abstract is a very practical skill, which can help us achieve more accurate content presentation.Why do you need to get the actual character length of the article summary?The article abstract is the core essence of the content, usually used on list pages
In AnQi CMS template development, the `index` filter is a very practical tool that helps us locate the position of a specific substring in a string.However, when dealing with content containing Chinese characters, its performance in position calculation may confuse some users.How many positions does a Chinese character occupy in the `index` filter?What kind of logic is hidden behind this? Let's delve deeper together.### `index` filter's working principle In simple terms
