How to convert a string of English characters to uppercase, lowercase, or capitalize the first letter of each word?

As a senior CMS website operation personnel for a security company, I am well aware of the importance of fine-grained content presentation in attracting and retaining users.When dealing with website content, the format of the text often determines its professionalism and readability.The Anqi CMS provides a powerful and flexible template engine that can help us easily convert various text formats, such as converting English strings to uppercase, lowercase, or capitalize the first letter of each word.

AnQiCMS template engine string case conversion

The AnQiCMS template engine borrows the syntax of the Django template engine, allowing us to use the pipe character|Use various built-in filters (filters) to process variables.These filters can be conveniently applied to any English string variable to meet different display requirements, ensuring consistency and professionalism.

Convert to uppercase

In many scenarios, such as titles, emphasized text, or specific layout requirements, we need to convert all English strings to uppercase. The Anqi CMS template engine provides|upperFilter. When you process a variable through this filter, all letters in the English string contained in the variable will be converted to uppercase.

For example, if your template has a variable namedproductNamewith a value of"anqicms platform", you can convert it to uppercase in the following way:

{{ productName|upper }}

This will output:ANQICMS PLATFORM

Convert to lowercase letters

Similar to uppercase conversion, sometimes we need to ensure that English strings are presented in full lowercase form, for example, for unified tags, URL paths, or certain style rules. The Anqi CMS template engine's|lowerFilter can achieve this function. It will convert all uppercase letters in the target string to lowercase letters.

Continue as above.productNameVariable as an example, if its value is"AnQiCMS Platform"you can use|lowerThe filter converts it to lowercase:

{{ productName|lower }}

This will output:anqicms platform

The first letter of each word is capitalized (title case)

For text that needs to be presented formally, such as article titles, names, place names, or other formal text, it is often required that each word starts with a capital letter and the rest are lowercase. This is a variant of 'title case' or 'camel case'. The Anqi CMS template engine's|titleThe filter is designed for this purpose. It identifies each word in the string and converts the first letter of each word to uppercase while converting the rest to lowercase.

For example,articleTitlevariable's value is"how to use anqicms efficiently"You can apply|titlea filter to format it:

{{ articleTitle|title }}

This will output:How To Use Anqicms Efficiently

It should be noted that if you only need to capitalize the first letter of the entire string (for example, for the beginning of a sentence), while keeping the other letters unchanged, you can use|capfirstFilter. However, for the need of "capitalizing the first letter of each word"|titleFilter is a more precise choice.

Concluding remarks
