What is the global $wp object used for?

programmeradmin8浏览0评论

In the wordpress documentation for Global Variables, I did not find information about the $wp global variable.

I found a plugin which declares the global $wp variable as follows:

public function login_form(){
   global $wp;
   ...
}

But this variable is never used inside the declared function, so I wonder what is going on.

The entire function can be found here (links to the exact line in the GitHub WordPress Frontend Profile plugin)

  • It is a global instance of WP environment setup class and listed among the other global variables under the link you provided. – Ivan Shatsky Commented Jul 16, 2020 at 14:57
  • 1 Use of the main $wp object in plugins and themes is extremely rare, and is usually a bad sign of code quality. In the example you linked to, it isn't even used, the line could be deleted and it would make no difference – Tom J Nowell Commented Jul 16, 2020 at 15:17

Reset to default 3

It contains the main instance of the WP class, which is primarily responsible for parsing the request URL and querying the appropriate posts, as well as sending headers and handling 404s. It can be used for things like getting the current request URL.

If it's declared in a function but not used, it's likely a mistake, or left over from a previous version of the function that did use it. You would need to ask the plugin developer why.
