Hi,

I've tried the above code. I'm able to add a custom charge and update the basket total. I want to add a condition whether the basket contains this custom charge or not. How can I add this?

Hello,

you should be able to do something like this:

<!-- if the l.settings:basket or l.settings:global_minibasket data is already on the page... -->
<mvt:assign name="l.found_custom_charge" value="miva_array_filter( l.settings:basket:charges, 0, l.charge, 'l.charge:type EQ \'CUSTOM_CHARGE\'', l.custom_charges )" />
<!-- OR if you need to load the data... -->
<mvt:do file="g.Module_Library_DB" name="l.found_custom_charge" value="BasketChargeList_Load_Type( g.Basket:basket_id, 'CUSTOM_CHARGE', l.custom_charges )" />

<mvt:if expr="l.found_custom_charge">
	<mvt:assign name="g.mvt_debug" value="glosub( miva_array_serialize( l.custom_charges ), ',', asciichar( 10 ) )" />
	<!--
	@@custom_charges
	===========
	&mvt:global:mvt_debug;
	-->
</mvt:if>
