Change Router in Magento

I have a link like below:

index.php/catalog/product/offer/id/1/cid/100/

• id param means the id of product

• cid param means the id of customer

Now if I want to change this link how to match with a router like:

index.php/offer开发者_StackOverflow中文版/id/1/cid/100/

How can I do that?

If you have a finite set of ID values you can create an equal number of rewrite rules like this. The idea there is to map (ie. one-to-one) every possible URL to a shortened form.

However since the number of customers is out of your control it might be better to use a legacy XML rewrite as described in the Magento Wiki.

<config>
    ...
    <global>
        <rewrite>
            <vietean_catalog_product_offer>
                <from><![CDATA[#^offer/#]]></from>
                <to>catalog/product/offer/</to>
            </vietean_catalog_product_offer>
        </rewrite>
    </global>
</config>

If that doesn't work the third option is to form URLs like index.php/offer?id=1&cid=100 which isn't as pretty. The URL will then translate into offer/index/index. Give your existing router the front name of offer, name the controller IndexController and the action indexAction.

<config>
    ...
    <frontend>
        <routers>
            <vietean_example> <!-- This tag can be any unique value -->
                <use>standard</use> <!-- standard because it's the frontend -->
                <args>
                    <module>Vietean_Example</module>
                    <frontName>offer</frontName> <!-- First part of URLs -->
                </args>
            </vietean_example>
        </routers>
    </frontend>
</config>

The controller can access the URL parameters in the exact same way as before;

$id = $this->getRequest()->get('id');
$cid = $this->getRequest()->get('cid');
