Steps to implement the express delivery range restriction function in PHP Developer City

With the development of e-commerce, more and more malls provide delivery services. In order to ensure the accuracy and efficiency of delivery, many malls will limit the scope of delivery. This article will introduce how to use the express delivery range restriction function in PHP Developer City.

Step one: Obtain delivery range data

First, we need to obtain express delivery range data. These data can be managed through a database table, which contains distribution range information for each region. We can define a region table, including the following fields: region ID, region name, delivery range, etc. By querying the database, we can obtain delivery range data.

Step 2: Obtain user address information

When the user places an order, we need to obtain the user's address information. You can collect the user's address information by writing a front-end page, or obtain the user's address information through some third-party interfaces.

Step 3: Determine whether the delivery range meets the requirements

After we obtain the user's address information, we need to compare it with the delivery range to determine whether it meets the requirements. You can use some open source geographical location calculation libraries, such as Baidu Map API, to calculate the distance between the user's address and the express delivery range. Based on the calculation results, we can get a distance value and then compare it with the delivery range.

Step 4: Prompt the user for delivery range restriction information

If the user's address is not within the express delivery range, we need to give the user a prompt message to inform them that the current address cannot be delivered. This can be achieved through pop-up windows, prompts, or page jumps. In the prompt message, we can explain the reasons why delivery cannot be made and provide some suggestions, such as choosing other delivery methods or changing addresses.

Step 5: Process orders that meet the delivery range

If the user's address is within the express delivery range, we can continue to process the order. You can call the express interface to pass the delivery information to the express company. At the same time, we can save the user's address information to the order table to facilitate subsequent query and processing.

Step Six: Later Maintenance and Update of Delivery Scope

The delivery scope is a dynamic concept. With the development of the mall and the expansion of the business, the delivery scope may need to be updated at any time. In order to facilitate the later maintenance and update of the delivery scope, we can write a backend management page for the administrator to add, delete, modify and check the delivery scope data. At the same time, we can also use the caching mechanism to improve the efficiency of data query and avoid frequent database queries.

Summary:

Through the above steps, we can realize the express delivery range restriction function in the mall. By obtaining delivery range data, obtaining user address information, and determining whether the delivery range meets the requirements, we can effectively control the delivery range and improve delivery accuracy and efficiency. At the same time, we can also ensure the smooth progress of the mall business through post-maintenance and updating the delivery scope.
