SQL code help

[arjundass]

I have created a new field in orders table named date_expiration.

I have added this line "" $fields['date_expiration'] = pSQL($this->date_add); "" , to populate this field .

I want to add 90 days + date_add to date_expiration field .

Kindly help.

this is php code, not sql

if $this->date_add is unix timestamp you may add the number of seconds 3600*24*90

if $this->date_add is string convert it to time with DateTime::createFromFormat() first, then add seconds.

Find the similar example in classes/Discount.php at the end of createOrderDiscount function.
