Expresso Store match specific UK postcodes

expresso_store_uk_postcodes.txt

Allow shipping rules to accept regex
***************************************************************

First, change the `postcode` column in `exp_store_shipping_rules` to type varchar(255).

./Store/src/Service/ShippingService.php

Change this:

    /**
     * Match postcode glob patterns, for example 123* or 123?
     */
    protected function glob_match($pattern, $subject)
    {
        // convert glob pattern to regex
        $regex = '/^'.str_replace(array('\*', '\?'), array('.*', '.'), preg_quote($pattern, '/')).'$/i';

        return (bool) preg_match($regex, $subject);
    }


To this:

    /**
     * HACK: Match UK postcode pattern
     */
    protected function glob_match($pattern, $subject)
    {
        // remove spaces
        $subject = str_replace(' ', '', $subject);

        // remove last 3 characters 
        $subject = substr($subject, 0, -3);

        // search for a match against our shipping rules
        return (bool) preg_match($pattern, $subject);
    }
