We had a Drupal project, implementing a commerce site for a local store. We use Drupal Commerce, as always, for this type of websites. You may see that we have alot of Drupal Commerce themes on our portfolio.
During the project, there was a minor request from our customer: add the Continue Shopping button to the cart. This feature is available on Ubercart, especially for Drupal 6 Ubercart users. Most of ecommerce sites have this feature as well. But it is not built-in with Drupal Commerce.
As I searched on the Drupal.org issues, I found a very helpful thread: Continue shopping in cart. Zorroposada presented a custom code to achieve it:
<?php
/**
* Implements hook_form_FORM_ID_alter(&$form, &$form_state, $form_id)
*/
function MYMODULE_form_views_form_commerce_cart_form_default_alter(&$form, &$form_state, $form_id) {
$form['actions']['continue_shopping'] = array(
'#type' => 'button',
'#value' => t('Continue Shopping'),
'#weight' => -999,
);
if (isset($_SERVER['HTTP_REFERER']) && strlen($_SERVER['HTTP_REFERER'])) {
// if user comes from product detail page, redirect user to previous page
$form['actions']['continue_shopping']['#attributes'] = array('ONCLICK' => "history.go(-1); return false;");
} else {
// redirect user to product list page 'store' by default
$form['actions']['continue_shopping']['#attributes'] = array('ONCLICK' => "window.location.href='" . url('store') . "'; return false;");
}
}
?>
I do nothing better here. I just wrap this code on a custom module, so any lazy users can just download and install it.
The module is called "Commerce Continue Shopping", and you will find it in the Other section of the Drupal module page when unzip it to /sites/all/modules. Enable it and you will see the Continue Shopping button on your cart.
Pls download the module here: commerce_continue_shopping_7.x-1.0.zip
