`wp_parse_str` as used by `add_query_arg` breaks URLs with the same query var name used multiple times

wp_parse_str as used by add_query_arg breaks URLs with the same query var name used multiple times.

To reproduce the problem, just add this inside any theme or plugin:

add_action( 'wp_enqueue_scripts', 'my_google_fonts_enqueue_styles' );
function my_google_fonts_enqueue_styles() {

The resulting link tag will be:

<link rel='stylesheet' id='my-google-fonts-1234567890'  href=';display=swap&#038;ver=3.2.0' media='all' />

The expected result is:

<link rel='stylesheet' id='my-google-fonts-1234567890'  href=';display=swap&#038;ver=3.2.0' media='all' />

IMHO, this is a problem with Google's interface and how they have implemented their style URLs using the same query parameter twice instead of using something like family[]=, but with so many WP users using Google Fonts, I believe this should be fixed.

  • Version trunk deleted

Noting that wp_parse_str() is currently a simple wrapper for PHP's own parse_str() function. The behaviour we are seeing here is also documented in a user note.

Since we already have this wrapper we could include a possible fix there.

Change the last parameter '3.2.0' to null (not false - that will just add the WP version).
The 'ver' prameter is used for cache-busting resources hosted on your site. So it's irrelevant when linking to external resources.
ie. you shouldn't add the 'ver' parameter to any external sources anyway.
