Magento: Cant find template

I see a call

<?php echo $t开发者_C百科his->getChildHtml('coupon') ?>

in cart.phtml. I cannot find this file anywhere. I am new to Magento, Could you tell me a location where this file should ideally reside? Also, do these templates also load from Database and should I check there/

Kind regards Khuram

To find this you need to do a little bit of tracing :).

We need to look in a "layout.xml" file since this is where "ChildHtml" blocks are declared. Since this is the Cart,which is part of the Checkout module, we need to look in checkout.xml.

You should find the line declaring the "coupon" block under the checkout_cart_index section of this file. Here it is:

<block type="checkout/cart_coupon" name="checkout.cart.coupon" as="coupon" template="checkout/cart/coupon.phtml"/>

So, checkout/cart/coupon.phtml is the template file you are looking for. You can see it is assigned the name "coupon" with the as="coupon" line.

This file will probably be in the folder /app/design/frontend/default/default/checkout/cart/coupon.phtml and you should copy it your custom theme directory, which will automatically override the default and use your new coupon.phtml template file.

I hope this helps, and happy Magentoing
