Prestashop 1.7.4 hooks question

[ps2k11]

trying to figure out ps 1.7.4 regarding hooks

need to make some changes in order display detail and display cart rule vouchers but don't know where to look

{$HOOK_DISPLAYORDERDETAIL nofilter}

{hook h="displayCartRuleCartVoucher" discounts=$cart.vouchers}

no clue where to look for the actual code to modify, if anybody can point that out I'll appreciate it

it's ok figured it out but in phpmyadmin no module linked to $HOOK_DISPLAYORDERDETAIL

It's quite possible that no module is using any particular hook. Hooks is to modify the default behavior of the PS default code (so it's not necessary that PS itself is using that hook to display details).

You can register the hook from your module to use any particular hook.
