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

UsecapfirstFilter: Implement capitalization of the first letter

If you want to capitalize the first letter of the English nameof the entire stringYou can usecapfirstFilter. This filter will only focus on the first character of a string, and if it is an English letter, it will convert it to uppercase while keeping the other characters unchanged.

Assuming you collect a user's name through a form, and use it in a template like this:user.FirstNameoruser.FullNameYou 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, regardless of whether the user submits 'john' or 'JOHN', it passes throughcapfirstProcessed, all will be displayed in the form of "John", effectively standardizing the display format.

UsetitleFilter: Capitalize the first letter of each word.

很多时候，用户提交的姓名可能包含多个单词，比如英文全名 “john doe”。如果只使用 EnglishcapfirstFilter, then only the 'J' of 'john' will be uppercase, while the 'd' of 'doe' will remain lowercase, displaying as 'John doe', which may not be the effect we want.

In this case,titleFilter is more appropriate. It can capitalize the first letter of the stringof each word.Convert all to uppercase, and the rest to lowercase. This is very useful for displaying names in standard English format.

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 identify words and perform uppercase conversion, ensuring professionalism and consistency in the display of full names.
