Functions

Generate promo code

To generate a promo code, call the generate() method. The method accepts the following parameters:

• $length (optional): The length of the promo code. Default is 8.
• $prefix (optional): A prefix to add to the promo code. Default is an empty string.
• $discount (optional): The discount amount. Default is 0.
• $maxUses (optional): The maximum number of times the promo code can be used. Default is null.
• $validFrom (optional): The date and time from which the promo code is valid. Default is null.
• $validTo (optional): The date and time until which the promo code is valid. Default is null.

Example:

PromoCodes::generate(10, 'DISCOUNT', 10, 100, '2022-01-01 00:00:00', '2022-12-31 23:59:59');

Validate promocode

To validate a promo code, call the validate() method. The method accepts the promo code as a parameter and returns either the promo code object if it is valid or an array with an error message if it is invalid.

Example usage:

PromoCodes::validate('DISCOUNT-5D8S0A5K5L')

// returns ['status' => false, 'message' => 'Reason why code is not valid']

or

// returns ['status' => true, 'code' => 'code details']

Apply code

To apply the promocode use the apply() method. The method accepts the promo code as a parameter and returns either the promo code object if it is valid or an array with an error message if it is invalid.

Example usage: PromoCodes::apply('DISCOUNT-5D8S0A5K5L')

Calculate the discounted amount

To calculate the discounted amount after applying a promo code, call the calculate() method. The method accepts the following parameters:

• $amount: The original amount before the discount.
• $discount_type: The type of discount, either 'percentage' or 'fixed'.
• $discount_amount: The amount of the discount.

PromoCodes::calculate(100, 'percentage', 10)
