I have a rule

Redirect to cart after adding a registration

this rule works exactly as planned.


New scenario and new rule, If the user empties their cart of all products, I want to redirect to previous page (the sending page).

New rule

Redirect user to originating page after removing all items from cart

I have the Event and the Conditions but I don't see how to massage the originating address that was used to get to the cart. The originating form action is <input type="submit" id="edit-submit" name="op" value="Add to cart" class="form-submit">.

{ "rules_redirect_user_to_originating_page_after_removing_all_items" : {
    "LABEL" : "Redirect user to originating page after removing all items from cart",
    "PLUGIN" : "reaction rule",
    "OWNER" : "rules",
    "TAGS" : [ "Cart" ],
    "REQUIRES" : [ "rules", "commerce_cart" ],
    "ON" : { "commerce_cart_product_remove" : [] },
    "IF" : [ { "data_is_empty" : { "data" : [ "quantity" ] } } ],
    "DO" : []
  }
}

Can anyone help?

In your first rule "Redirect to cart after adding a registration" you probably are using a "Page redirect" action. If so you can do the following.

Edit this action and set "APPEND DESTINATION PARAMETER" to true (see screenshot). This will add the referring page as a query parameter to your url e.g. example.com/cart?destination=node/3

Then in your second rule you can retrieve this destination parameter by using the function drupal_get_destination. Use the return value of that function in the drupal_goto function and the user will be redirected to the url they were coming from.

{ "rules_redirect_user_to_originating_page_after_removing_all_items" : {
    "LABEL" : "Redirect user to originating page after removing all items from cart",
    "PLUGIN" : "reaction rule",
    "OWNER" : "rules",
    "TAGS" : [ "Cart" ],
    "REQUIRES" : [ "php", "rules", "commerce_cart" ],
    "ON" : { "commerce_cart_product_remove" : [] },
    "DO" : [
      { "php_eval" : { "code" : "drupal_goto (drupal_get_destination());" } }
    ]
  }
}

  • this definitely worked and I learned an advanced aspect to Rules. Is there any security issue in displaying this publicly? Technically it is within the commerce context of the site.

  • If I can see the path in the address bar are there any hackable parts or ways to hack the address for any evil intentions? just paranoid ...

  • drupal_goto() calls url() which does sanitizing but always double check for yourself :) api.drupal.org/comment/59556#comment-59556

  • This solution worked too well. After registration and approving a product in the cart, the reroute kicked me back to the previous page. Got tons of notice from the Pantheon site audit about bad habits and having PHP format active. So ... I am working on something different for now. I appreciate the reminder though about making sure I bring what I need into scope for getting Rules access to it.

using php_eval and drupal_goto is not good solution ( although you can get drupal_get_destination there, but if user remove lineitems on /cart what happened ? again redirect to empty cart page ) I suggest Use Page Redirect to Url Action and redirect user to your front page or your products page.

"DO" : [ { "redirect" : { "url" : "<front>" } } ]

  • yeah I think I know what you mean, although in your second explanation it looks like you are talking about the same two uses cases. I was re-reading the question from the OP though and playing with it a bit more (adding multiple products) and then indeed, if you add multiple products it will be a problem where you want to redirect the user to, the first or the second product for instance. OP is also talking about redirecting to cart after registration so I'm not entirely sure if one or multiple products get added in that process.
