Shortcode attributes get transferred to lowercase

[DekiGk]

Hello WP team,

In the WP codex it clearly states that we can use uppercase or lowercase letters for our shortcode attribute names:

"Attribute names are optional and should contain only the following characters for compatibility across all platforms:

Upper-case and lower-case letters: A-Z a-z
Digits: 0-9
Underscore: _
Hyphen: - (Not allowed before version 4.3.0)"

​http://codex.wordpress.org/Shortcode_API#Attributes

However, when I was doing one shortcode today the WP seems to have transferred my "current_post_ID" to "current_post_id".

Through the help of my WordPress Serbia facebook network I have found out that this is because the function: "get_shortcode_atts_regex" has strtolower while parsing.

Can we change the codex to reflect that?

Best Regards,
Dejan Kostevski

Hi, and welcome!

The codex is just a wiki, and by logging in with your WordPress.org username and password you can freely edit any page that needs some attention there, without the need for a ticket on here.

I've made the modification to the article for now, but I do believe they should always be lowercase in the backend and are permitted to use mixed case in the actual editor to simplify the input for the end user.

Hello,

Thanks. Oh, I didn`t know I can do that myself.

I disagree with the above because:

current_post_ID
current_post_id
Current_Post_Id

are 3 different names.

Anyhow, thanks for your help. Case closed. :D
