how to pass parameters or variables from one controller to another in prestashop

[NishantVadgama]

I want to pass parameters or variables from one controller to another.

for example what actually I want to do is.

I have override PaymentModule's validateOrder() method from that method I have to pass array data like cart info etc

to my modules OrderConfirmation hook function.

From paymentModule to order confirmation? You can try executing the hook directly... but all modules hooked there will run. I sggest you find a workaround as this would breaks the already broken mvc pattern prestashop has. Why not assigning the array from a module hooking there?

Sir..! I have implemented that hook into my module's php file only and not executing that hook but I want to pass array variable from that overrided PaymentModule's validateOrder() method to hookDisplayOrderConfirmation($params){} method which is in my modules php file. how can I done that..?

[NemoPS]

hm, it sounds tough. You can't pass a parameter there as the paymentmodule class runs on a different page compared to the order confirmation, so at a different time. You need to store the value/s in the db (serialized, perhaps), and get them back

absolutely I have thought about that way but Im confuse about how long database will increase day by day transaction..?

Well you're right, but I see no other way around it honestly Try with a simple column added to the ps_order tab

Actually I have added already two column in ps_order table , ok then if there is no option so I'll create one table and store my array to that and later on access in hook. thanks nemo for helping in my development
