How do I clear a custom upcharge and update total on BASK?

[dreamingdigital]

All this needs to happen on the same page without any reloads

This clears a custom upcharge

<mvt:assign name="g.customCharge:type" value="'CustomUpcharge'" />
<mvt:do file="g.Module_Library_DB" name="l.successClearingCharges" value="BasketCharge_Delete_All_Type( g.basket:basket_id, g.customCharge:type )" />

And This Reloads the basket charges:

<mvt:do file="g.Module_Library_DB" name="l.successSettingItems" value="BasketChargeList_Load_Basket( g.basket:basket_id, l.settings:basket:groups )" />

But how do I reload everything else because the "total" via &mvt:basket:formatted_total; is still including the cleared charges.

Place your detection and delete code at the top of the page, and inside that conditional run the Template Render function:

<mvt:do name="l.result" file="g.Module_Feature_TUI_MGR" value="TemplateManager_Render_Page( 'ABUS' )" />

It does mean you are loading the basket twice, but with SMT code, I think that's your only choice outside of doing the delete via ajax and rendering the page.

Bruce, that might work, I'm just wondering how that wouldn't cause an endless loop on the BASK page. Or maybe I need more coffee and should think about this again later.

The refresh would not have the conditional attached which triggered the changes.

It's possible to write some template code that will update basket variables such as :formatted_total to the correct values. Note that this code might have to be in the global header, in order to make sure that it updates the mini-basket display, if you're concerned about that.

There are a couple of utility modules available that let you run template code during the "Action" processing, before the store starts rendering pages. One of these modules is available from me; let me know if you're interested in a copy.

Also, FYI, there appears to be a bug in one of your code snippets. Your call to BasketChargeList_Load_Basket writes the data into l.settings:basket:groups; I think you want l.settings:basket:charges for that.

Personally, I'd do this as a custom module so everything that needs to happen can be done in between the 'update' post and the subsequent page load...if that's what Kent's module does, then that is the better route as you are not loading the page twice.

Yes, that's what my module does. It uses page templates for the "custom" parts, so an off-the-shelf module can serve many purposes.
