AnQiCMS's template engine uses a syntax similar to Django, which includes many practical filters (Filters) to help us easily handle text content, including case conversion.

UsecapfirstFilter: Implement Capitalization of the First Letter

If you want to capitalize the English nameThe first letter of the entire stringSubmitted by the user, you can use to convert it to uppercasecapfirstFilter. This filter focuses only on the first character of a string. If it is an English letter, it will convert it to uppercase, while the other characters in the string remain unchanged.

Suppose you collect the user's name through a form and use such a variable to receive it in the template. You can use it in the template file like this:user.FirstNameoruser.FullNameSuch a variable to receive. You can use it in the template file like this:

{# 假设 user.FirstName 的值是 "john" #}
<p>欢迎您，{{ user.FirstName|capfirst }}！</p>
{# 显示结果将是：欢迎您，John！ #}

{# 假设 user.LastName 的值是 "doe" #}
<p>姓氏：{{ user.LastName|capfirst }}</p>
{# 显示结果将是：姓氏：Doe #}

Through this simple filter, whether the user submits 'john' or 'JOHN', it goes throughcapfirstAfter processing, it will be displayed in the form of “John”, effectively standardizing the display format.

UsetitleFilter: Implement the capitalization of the first letter of each word.

Most of the time, the names submitted by users may contain multiple words, such as the full English name "john doe". If only usingcapfirstThe filter, so only the 'J' in 'john' will be capitalized, while the 'd' in 'doe' remains lowercase, displaying as 'John doe', which may not be the desired effect.

In this case,titleThe filter is more suitable. It can extract the initial letters of words from a string.The initial letter of each word.Convert to uppercase and the rest to lowercase. This is very useful for displaying standard English names in a formatted manner.

Let's look at an example:

{# 假设 user.FullName 的值是 "john doe" #}
<p>姓名：{{ user.FullName|title }}</p>
{# 显示结果将是：姓名：John Doe #}

{# 即使是 "peter van der merwe" 这种复杂一些的名字 #}
{% set userName = "peter van der merwe" %}
<p>姓名：{{ userName|title }}</p>
{# 显示结果将是：姓名：Peter Van Der Merwe #}

As you can see,titleThe filter can intelligently recognize words and perform uppercase conversion, ensuring professionalism and uniformity in displaying full names.
