How to use a DOT (.) in a product URL

Question

I wonder if it is possible to use a DOT (.) in a product URL in Magento. I want to create a product URL that looks something like this:

http://www.domain.com/galaxy-tab4-10.1.html

But when I try to do this then after saving the product the DOT in 10.1 is automatically changed in a DASH (-) and the URL becomes:

http://www.domain.com/galaxy-tab4-10-1.html

I have seen other websites that have DOTs in the path part of their URLs. I'm not sure why Magento doesn't accept them.

Any thoughts are welcome!

Answer 1

You need to rewrite this method: Mage_Catalog_Model_Product_Url::formatUrlKey().
You need to change this line:

$urlKey = preg_replace('#[^0-9a-z]+#i', '-', Mage::helper('catalog/product_url')->format($str));

What this basically means is, 'replace anything that's not alphanumeric with -'.
You need to make it allow dots also. Just add a dot in the regular expression. #[^0-9a-z\.]+#i
(not sure if it should be escaped \. - test them both).
Seams like it should be escaped.
Thanks @FabianBlechschmidt for the crash course in regex.

Not Sure if this fulfill your requirement, Magento has feature to manage url for products
