If $home_path=='wp' then WP::parse_request() will remove 'wp' from 'wp-json/wc/v1/products' in $pathinfo

[Magenta Cuda]

I have installed WordPress in a subdirectory 'wp' so $home_path is 'wp'. The statement

pathinfo = preg_replace( $home_path_regex, '', $pathinfo );

is called with arguments

$home_path_regex = '|^wp|i'
$pathinfo = 'wp-json/wc/v1/products'

and returns

$pathinfo = '-json/wc/v1/products'

Since, $_SERVER[ 'PATH_INFO' ] is the trailing part of the path wouldn't the leading home path be already removed?

Here is the $_SERVER variable:

Hey @Magenta-Cuda and welcome back to Trac.

In most cases, PHP_INFO should only be the trailing component, however that's not always the case unfortunately.
IIS (particularly older versions I think) actually pass the whole REQUEST_URI in there - see ​https://msdn.microsoft.com/en-us/library/ms524602(v=vs.90).aspx

I'm wondering if we can change this regex to effectively be:

$home_path_regex = '!^wp(?:/|$)!i'
$pathinfo = 'wp-json/wc/v1/products'
