Discuz user ID modification method sharing, easy to do, need specific code examples

In the Discuz forum system, the user ID is a unique number that identifies the user, usually determined by the system Automatic generated. But in certain circumstances, such as needing to migrate users from one system to another, or needing to manually modify the user ID to meet business needs, we may need to modify the user ID. This article will share a method to modify the Discuz user ID and provide specific code examples to help you solve this problem easily.

The method of modifying the Discuz user ID mainly includes the following steps:

1. Back up the database: Before making any modifications, be sure to back up the Discuz database to prevent data loss or damage.

2. Find the user ID that needs to be modified: First, you need to determine the ID of the user to be modified. You can obtain the user's detailed information through Discuz's backend management system or database query.

3. Modify the ID field in the user table: directly modify the ID field of the corresponding user in the Discuz user table (usually starting with "pre_ucenter_members") through SQL statements. The specific SQL statement is as follows:

UPDATE pre_ucenter_members SET uid = '新用户ID' WHERE uid = '旧用户ID';

In the above SQL statement, replace "pre_ucenter_members" with the user table prefix you actually use, and replace "new user ID" with the new user ID you want to modify." Replace "Old User ID" with the old user ID you want to modify.

4. Modify related fields in related tables: In the Discuz system, user IDs are usually referenced by other tables, such as post tables, reply tables, etc. Therefore, the associated user ID fields in these tables need to be modified one by one through SQL statements. The following is an example:

UPDATE pre_forum_posts SET authorid = '新用户ID' WHERE authorid = '旧用户ID';

Through the above steps, you can successfully modify the Discuz user ID. However, it should be noted that when modifying the user ID, you must operate with caution to avoid affecting the normal operation of the system. At the same time, modifying the user ID may lead to inconsistencies in related data, so it is recommended to perform sufficient data cleaning and backup before modification.
