magento - Event Observer - Trigger an event -


i create event observer want show message / alert box when total weight of cart surpass 23 kg (to tell truth, want event check weight limit , trigger alert box when customer add product cart).

could me make such observer?

you don't need involved...

already have been given code write weight out, put code in block, put in header (or cart sidebar) , add if statement.

don't put

if($weight>23) { echo "too heavy - shopping cart going burst itselves!" }

put custom variable in admin , compare against that. in weigh, if change courier customer can update max weight.
