Basic Settings:
Pane:
Cart panes are used to build the display of the cart view page. You should keep the Default cart form enabled unless you have another module providing alternate functionality. Using the menu here you may enable/disable any of the panes and adjust their display order by changing their weight.
Display a message when a customer adds an item to their cart:
This option is self-explanatory.
Add to cart redirect:
There is a text box that lets you enter the redirect URL for a customer who has added an item to his or her cart. By default, this redirects to the shopping cart view page. You may leave this field blank or enter <none> to disable the redirect or enter any other Backdrop CMS path to redirect to upon adding an item.
Show an "Empty cart" button on the cart page.:
This option will show an option to remove all items from the shopping cart or Empty the shopping cart.
Minimum order subtotal:
There is a text box which lets you specify a minimum order subtotal for checkout if applicable for your store. Customers who attempt to proceed to checkout will see an error message indicating the store's minimum order total.
Cart Lifetime:
Anonymous users:
The anonymous cart settings section lets you specify how long products should sit in an anonymous user's cart before they are removed from the database. For this to work properly, you must have a cron job running for your Backdrop CMS site. Backdrop CMS now includes an automated cron task by default, you should only need to change this if it causes problems with your site. See also Backdrop's cron job documentation.
Authenticated users:
This section lets you adjust the setting for an authenticated user (anyone who has logged in to your site).
Continue shopping element:
These settings relate to the "continue shopping" function on the cart view page. You may specify whether it should be a text link a button element or not displayed.
Make continue shopping go back to the last item that was added to the cart.:
If this is disabled or the item is unavailable, the default URL specified below will be used.
Default continue shopping destination:
You may set a link to direct your customers to any other page you want (like back to the catalog) or just remove it altogether by wiping out the URL and text settings.
Cart page breadcrumb:
Backdrop automatically adds a Home breadcrumb to the cart page, or you can use these settings to specify a custom breadcrumb. Add the text and the destination URL.
Shopping Cart Block:
You can add the Shopping Cart block to any of Backdrop CMSs Layouts.
To add a "Shopping Cart" block to a layout go to Structure » Layouts (/admin/structure/layouts) and click on "Manage Blocks" for the layout you would like to configure. Select the region where you would like the "Shopping Cart" block to appear and click "Add block". Search for the "Shopping cart" block by starting to type "shop"; the "Shopping Cart" block should appear. Click on the title "Shopping Cart" to add and configure your shopping cart.
Block title type:
The select list should have "default" as the initial option, this will display the default name for the shopping cart, which as you can imagine is "Shopping Cart".
The other options are "Custom" and "None". Custom, allows you to enter your own title for this shopping cart while "None" will hide the title.
The next five select boxes are pretty self-explanatory
- Hide block if cart is empty.
- Display the shopping cart icon in the block title.
- Make the shopping cart block collapsible by clicking the name or arrow.
- Display the shopping cart block collapsed by default.
- Display small help text in the shopping cart block.
The remaining options are standard Block settings which include: -
- Style settings
- Visibility conditions
- Admin label
