How to convert English string to uppercase, lowercase, or capitalize each word?

As a senior CMS website operation personnel of a well-known security company, I am well aware of the importance of refined content presentation in attracting and retaining users.When handling website content, the format of the text often determines its professionalism and readability.AnQi CMS provides a powerful and flexible template engine that can help us easily achieve various text format conversions, such as converting English strings to uppercase, lowercase, or capitalizing the first letter of each word.

String case conversion in AnQiCMS template engine

The template engine of AnQiCMS has borrowed the syntax of Django template engine, allowing us to use the pipe symbol|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 and ensure consistency and professionalism.

Convert to Uppercase

Under many scenarios, such as for titles, emphasized text, or specific layout requirements, we need to convert English strings to uppercase. Anqi CMS template engine provides for this|upperThe filter. When you pass a variable through this filter, all letters in the English string it contains will be converted to uppercase.

For example, if your template has a nameproductNameThe variable, its value is"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 lowercase, such as for unified labels, URL paths, or certain style rules. The AnQi CMS template engine's|lowerThe filter can implement this function. It will convert all uppercase letters in the target string to lowercase.

Continue with the aboveproductNamevariable, if its value is"AnQiCMS Platform"You can use|lowerFilter and convert to lowercase:

{{ productName|lower }}

This will output:anqicms platform

Capitalize the first letter of each word (title format)

For article titles, names, place names, or other formal text presentations, it is usually required that each word have its first letter capitalized and the rest in lowercase, which is a variant of 'title case' or 'camel case'. AnQi CMS template engine's|titleThe filter is designed for this purpose. It identifies each word in the string and capitalizes the first letter of each word while converting the rest to lowercase.

For example, ifarticleTitlethe value of the variable 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, at the beginning of a sentence), and keep the other letters unchanged, you can use|capfirstFilter. However, for the need of 'capitalize the first letter of each word',|titleFilter is a more precise choice.
