Implementation of free shipping function in PHP mall

With the rapid development of e-commerce, online shopping has become the first choice for many people. For online shopping malls, setting up the free shipping function is a very important step. In this article, we will discuss how to implement free shipping function in PHP mall.

First of all, we need to understand what the free shipping function is. Simply put, the free shipping function means that merchants can mail goods to consumers for free if certain conditions are met. This condition can be set according to the actual situation of the merchant, such as over 100 yuan, over 200 yuan, etc.

Implementing the free shipping function in the PHP mall requires the following steps:

1. Set the free shipping conditions

First, we need to manage it in the background Free shipping conditions are set in the system, which are the conditions that consumers need to meet to enjoy free shipping services. This free shipping condition can be set according to the actual needs of the merchant, such as the total price of the product is over 100 yuan, the unit price of each product is not less than 20 yuan, etc.

While setting the free shipping conditions, we also need to consider whether to set some special rules. For example, if the total price of the goods in the same order reaches 500 yuan or more, you can enjoy the free shipping service.

2. Judge whether the total price of the goods in the shopping cart meets the free shipping conditions

After setting the free shipping conditions, we need to judge the total price of the goods in the shopping cart. to determine whether you can enjoy free shipping service. We first define a variable to store the total price of the current items in the shopping cart:

$total_price = 0;

Then, we need to traverse each item in the shopping cart and calculate The product of its unit price and quantity is then added to the $total_price variable, and finally the total price of the items in the shopping cart is obtained.

foreach($_SESSION['cart'] as $cart_item){

$total_price += $cart_item['price'] * $cart_item['quantity'];

}

After completing this step, we can get the total price of the items in the shopping cart , and then you can judge based on the free shipping conditions set by the merchant to decide whether to enjoy the free shipping service.

3. Implement the free shipping function

If the total price of the products in the current shopping cart has met the free shipping conditions we set, then we need to add the corresponding free shipping The service is applied to the order.

There are many ways to implement the free shipping function, so we need to choose based on our actual situation. A relatively simple method is to set the free shipping fee to 0, so that the product can be mailed for free.

There are some special circumstances that need to be considered when implementing the free shipping function in the PHP mall. For example, if a consumer purchases free shipping products and non-free shipping products at the same time, then we need to calculate the free shipping products and non-free shipping products separately, and apply different shipping strategies respectively.

4. Remind consumers to enjoy free shipping service

Finally, we need to consider another issue, which is how to remind consumers to enjoy free shipping service in the shopping cart. One method is to add a reminder area to the shopping cart page to remind consumers how many more items they need to purchase to enjoy the free shipping service.

In the process of implementing this function, we need to consider two points: First, we must ensure that the calculation is accurate, because many consumers may purchase more products because they are not clear that the free shipping conditions are met; second, we must ensure that the calculation is accurate. It is necessary to use some intuitive and vivid expressions to more easily attract consumers' attention.
