Howto add "view cart" button to ajax Shopping Cart preview

Quote

Post by efp » Mon Aug 08, 2011 5:08 pm

Hi.
Could someone tell me how i could add an extra button to the drop down cart preview in the header so it would link to main shopping cart page? (I know there is a separate link providing this functionality but i would like it to be in the cart preview, giving the option of viewing the full cart page or going to checkout)
I've searched the forum but havent found anything besides one other post exactly like mine which hasn't been answered.

Did you do it manually or did you use the vQmod file?

If you manually edited the files, please post the contents of your catalog/controller/checkout/cart.php file

My reason for asking is that the manual instructions clearly define 'button_viewcart'

$this->data['button_viewcart'] = $this->language->get('button_viewcart');

---

$this->data['button_checkout'] = $this->language->get('button_checkout');

is in the above file twice, as per the instructions, it is the 2nd occurrence of this line you need to edit.

I did it manually.
Although i've just tried it via the xml script and it works beautifully! (however i would still preffer to not use vqmod)

Here is mycatalog/controller/checkout/cart.php (part1)

Code: Select all

<?php

Hi!

How to make this work for 1.5.1.3! I´ve checked everything and it still gives undefined variable-error for button_viewcart.
