Fix for PHP8 – depreciated call to wp_localize_script

I’m running this plugin on WP Engine hosting and Php8 is a bit more strict on how it handles wp_localize_script().

The third parameter is expected to be an array, but a string is passed instead. This produces a depreciation notice throughout wp-admin.

It’s very easy to fix thanks to Query Monitor – just edit one line.

In wpengine-geoip/class-geoip.php, line 177 has a call to wp_localize_script().

Wrapping the third parameter in an array fixes it.

So it should read:

wp_localize_script( self::TEXT_DOMAIN . ‘-admin-js’, ‘nonce’, array(wp_create_nonce( self::TEXT_DOMAIN ) ));

If that change gets pushed to the repo, then all users of the plugin will benefit when the php8 switchover happens.
