In content operation, data analysis is an indispensable part.It can help us understand user behavior, evaluate content effectiveness, and guide future content strategies.AnQi CMS provides us with powerful data processing capabilities with its flexible template engine syntax, allowing us to perform some basic and practical data analysis directly at the template level.

Among them,countThe filter acts like an efficient 'data detective' that helps us quickly discern the frequency of specific elements in template data.Understand and make good use of this filter, which will greatly enhance our accuracy in content presentation and strategy formulation.

countFilter: The weapon of template data analysis

In simple terms,countThe filter is used to count the number of occurrences of a specified 'keyword' or 'substring' in a data source (such as a piece of text or a list).Its strength lies in its ability to not only handle continuous text information but also to make precise statistics on list data, providing us with intuitive quantitative data.

Basic usage:

countThe syntax of the filter is very intuitive:

{{ 数据源 | count: '要统计的关键词' }}

Here,数据源Can be any string variable in the template, such as article title, content summary, or array (or slice) variables, such as tag list, custom field list, etc.要统计的关键词This is the specific string or list item that you want to search for and count in the data source.

Advanced Application: Insight into Different Types of Data

countThe filter behaves differently on different types of data sources, making it very practical in various scenarios.

1. Keyword statistics in text content

When we want to know how many times a specific keyword is mentioned in an article, product description, or page content,countThe filter comes into play. It searches for all matching substrings in the entire string and returns their total count.

For example, we have an article summaryarchive.Description，想要统计其中“AnQiCMS”出现的次数：

<p>文章摘要中“AnQiCMS”共出现了：{{ archive.Description | count:'AnQiCMS' }} 次。</p>

Ifarchive.Description的内容是‘Welcome to AnQiCMS to build your website’AnQiCMS is efficient.”，那么上述代码将输出“2”，因为“AnQiCMS”这个子串出现了两次。

This feature is very valuable for SEO keyword density analysis, content quality assessment (such as, whether a certain topic word is fully mentioned), and other aspects.

2. English data in the list elements count

countThe filter can also be applied to array or slice type data.It will match each element in the array precisely, rather than a substring.This means that an item in the array must match the keyword you specify exactly in order to be counted.

Suppose we get a list of characteristics of an article through a custom field, such asfeatureListIt may be a["多站点管理", "灵活的内容模型", "多语言支持", "伪静态和301重定向管理"]Such a string array. We want to know how many items are about 'multi-language support':

{% set featureList = "多站点管理,灵活的内容模型,多语言支持,伪静态和301重定向管理"|split:"," %}
<p>该文章具备“多语言支持”特性：{{ featureList|count:"多语言支持" }} 项。</p>

IffeatureListContains "multi-language supportIf there is none, then output "0".This app scenario is especially useful in scenarios such as counting label usage frequency, product feature match degree, and user preference selection.

3. Combine conditional judgment to achieve dynamic content display

countThe number counted by the filter can serve as an important basis for template logic judgment, thus realizing more intelligent and dynamic content display.

For example, we can decide whether to display "Hot Topics" or "Core Content" prompts based on the frequency of a certain keyword appearing in the article content.

{% set cmsKeywordCount = archive.Content | count:'AnqiCMS' %}

{% if cmsKeywordCount > 5 %}
    <p class="tag tag-hot">文章内容中多次提及AnqiCMS，是核心主题。</p>
{% elif cmsKeywordCount > 0 %}
    <p class="tag tag-featured">文章内容提及AnqiCMS，但并非核心主题。</p>
{% else %}
    <p class="tag tag-general">文章内容未提及AnqiCMS。</p>
{% endif %}

Such dynamic display can not only enhance user experience but also help readers quickly grasp the key points of the article, improving the efficiency of information acquisition.

Improve operational efficiency:countThe value of the filter

MastercountFilter, allowing us to operate content in the Anqi CMS more skillfully. It not only provides a simple way to count data, but more importantly, these statistics can:

  • Optimize SEO:Quickly check the distribution of keywords in the article to avoid keyword stacking or make up for insufficient keyword use.
  • Improve content quality:Assist content creators in evaluating the coverage of the article on the core topic.
  • Personalized content recommendation:Dynamically recommend more relevant content based on user behavior or content characteristics statistics.
  • Improve data reports:Display key data indicators on the front-end page or in a custom report to enhance the intuitiveness of the report.

Using tips

  • The data source type is critical:Make sure to be clear about your数据源Is it a string or an array. For strings,countPerform substring matching; for arrays,countPerform exact element matching.
  • Combine with variable assignment:For complex logic or results that need to be referenced multiple times,{% set 变量名 = 数据源 | count: '关键词' %}The way to store the statistical results in a variable first and then perform subsequent operations can improve the readability and maintainability of the code.
  • Consider case sensitivity:When performing string statistics, please note whether the case of the keywords affects the matching results. In some template engines, string matching is case-sensitive.

Through these flexible applications,countThe filter undoubtedly can become a powerful assistant for the security CMS content operator, helping us to understand data more deeply and manage content more efficiently.

Common Questions (FAQ)

Q1:countFilter whether the statistics string distinguishes between uppercase and lowercase?A1: Yes,countThe filter is usually case-sensitive when counting substrings in a string.For example, "CMS" and "cms" are considered as different substrings.lowerorupperConvert both the data source and keywords to a uniform case format before counting.

Q2: How do I count the total number of occurrences of multiple different keywords in a text?A2:countThe filter can only count one keyword at a time. To count the total number of occurrences for multiple keywords, you can use the filter separately for each keyword and then add up the results. For example:countThe filter, then add up the results. For example:

{% set keyword1Count = archive.Content | count:'关键词A' %}
{% set keyword2Count = archive.Content | count:'关键词B' %}
{% set totalCount = keyword1Count + keyword2Count %}
<p>总共提及次数：{{ totalCount }}</p>

Q3:countThe filter can be used to count the occurrences of a specific number in a numeric array?A3: Yes. If your data source is a numeric array (such as[10, 20, 10, 30]），and you want to count the number10the number of occurrences,countThe filter applies as well. But remember, it will perform an exact match, that is, the elements in the array must be exactly consistent with the number you want to count. For example：

{% set numberList = [10, 20, 10, 30] %}
<p>数字10出现了：{{ numberList | count:10 }} 次。</p> {# 注意关键词10不需要引号 #}
