What it does:
A button will be added below the Delivery Address in Admin - Orders
It allows with one click to open Google Maps in a new browser tab and pass the delivery address into a search query.
Like this you'll save some copy paste to check if the address is accurate.
Compatibility: all OsCommerce 2.3 versions.
Can be adapted changing the button code to image button for 2.2 versions.
NOTE: A $replace _array is included for typical spanish street address cleanup. It removes stairs, floor and door numbering and other unnecessary details which prevent Google Maps to find the address.
You can add more strings to be stripped off for your needs.
Installation: Add a few lines of code to admin/orders.php
