With the development of e-commerce, price bargaining activities have become one of the common activities of more and more e-commerce websites. The characteristic of bargaining activities is that consumers can obtain more favorable prices by participating in the activities, while merchants can increase sales and brand awareness through the promotion of the activities. Today we will talk about how to use PHP to implement the price bargaining function.

1. Overview

The bargaining function generally consists of the following parts:

  1. Bargain initiation (the user clicks the button to initiate bargaining).
  2. Bargaining was successful (the user successfully cut off a certain amount).
  3. Bargaining failed (the user did not successfully cut off the amount).

In the entire process of bargaining, it is necessary to update the bargaining information and return the bargaining results for each bargaining request made by the user. Let's talk about the specific implementation method step by step.

2. Database design

The implementation of the bargaining function requires data storage, so the design of the database is required. Design the following three data tables:

  1. bargain_goods bargain product table

Fields: id (product ID), title (product title), image (product picture), price (original price of the product), bargain_price (lowest bargain price), start_time (bargain start time), end_time (bargain end time), status (bargain status)

  1. bargain_user Bargain user table

Fields: id (user ID), nickname (user nickname), avatar (user avatar)

  1. bargain_record bargaining record table

Fields: id (bargain record ID), user_id (bargain user ID), bargain_goods_id (bargain product ID), bargain_price (bargain amount), status (bargain status)

  1. Initiate bargaining

After the user clicks the button to initiate bargaining, he needs to perform the following operations:

  1. Determine the status of the bargained product. If bargaining is enabled, bargaining can be performed. , otherwise it will prompt that the bargaining activity has expired.
  2. Determine whether the user has bargained for a price. If so, it will prompt that the price has been bargained.
  3. According to the bargaining rules, generate the amount that the user needs to cut off, and add the bargaining record.

Regarding price bargaining rules, they can be formulated according to the actual situation of the merchant. For example, based on the original price and the lowest bargain price of the bargained item, the amount range that each user can discount can be calculated, and an amount value belonging to the user can be randomly generated.

  1. Bargaining Record Query

Users can know the amount they have cut off and the current bargaining progress at any time during the bargaining process. Therefore, it is necessary to provide the function of bargaining record query.

Bargaining records can be achieved by querying the bargaining record table. According to the current user's ID, query the corresponding bargaining record list. When returning to the list, the bargaining records need to be arranged in reverse chronological order so that users can see their latest bargaining records.

  1. Bargaining successful

After the user has cut off the specified amount, the following operations need to be performed:

  1. Update the bargained products Bargain price and condition of watch.
  2. Update the status of the bargaining record table.

When updating the bargain price and status of the bargain item, if the bargain item has reached the minimum bargain price, directly modify the bargain status to have been successfully bargained, otherwise just update the current Bargain the price.

  1. Bargaining failed

When the user haggles but does not reach the specified amount, a record of failed haggling needs to be added to the bargaining record table.

  1. Summary

Through the above implementation method, we can basically complete a simple PHP bargaining function. Of course, the bargaining business also involves some security issues, such as preventing users from cheating during the bargaining process. Some security mechanisms need to be designed and implemented according to specific situations.
