register_setting() page incorrectly refers to sanitization instead of validation

[McGuive7]

The .org page for register_setting() (​http://codex.wordpress.org/Function_Reference/register_setting) refers to the third parameter as $sanitize_callback, however in truth what this callback does is actually validation. The parameter should be listed as $validation_callback IMO.

Note: this is also present on the following page: ​http://codex.wordpress.org/Class_Reference/WP_Customize_Manager/add_setting

The Codex is a wiki. Anyone can edit it.

However, you should really look at developer.wordpress.org/reference, which is the official code reference. If there are errors there, they need to get fixed in the inline documentation, which you can do by filing a ticket in the core trac.

Additionally, this parameter is called "sanitize_callback" in the actual WordPress source code. The name is not chosen arbitrarily on the wiki page or in the documentation.

While I agree that the difference between "sanitization" and "validation" is a subtle one, this is what the code uses and how it defines it, therefore it should be documented as such.
