Discuz is currently one of the most popular forum systems in China. As an administrator, it is very important to master the method of adjusting the number of people online. During the operation of the forum, it is sometimes necessary to adjust the number of people online to meet specific needs or improve user experience. This article will introduce the Discuz online number adjustment method that forum administrators must know, and provide specific code examples to help administrators operate better.

1. How to display the number of people online

In the Discuz forum, there are generally two ways to display the number of people online: the default method and the Hook method.

1. Default method: Display the number of people online by setting the "online list time period" parameter in the background. Administrators can adjust the time period according to different needs. For example, users who are active within 30 minutes will be included in the number of people online.
2. Hook method: Display the number of online people by calling the corresponding API. This method is more flexible and the rules for calculating the number of online people can be customized as needed.

2. Method for adjusting the number of people online

1. Modify the default settings:

The administrator can log in to the backend management interface of Discuz and find the "Global ” - “Settings” - “User Settings” - “Online List Time Period”, here you can modify the time period for displaying the number of people online.

Code example:

// 修改在线列表时间段为15分钟
$_G['setting']['onlinelist'] = 15;

2. Using Hook method:

The administrator can customize the calculation rules for the number of people online through hook method. The following is a Simple sample code:

// 自定义计算在线人数规则
function custom_online_members() {
    // 自定义在线人数计算规则，如：
    $online_members = C::t('common_session')->fetch_all_online_member(600);
    return count($online_members);
}

// 注册 Hook
runhooks();

// 调用自定义在线人数方法
$custom_online_members = custom_online_members();

The above is about the method and specific code examples for adjusting the number of people online in Discuz. I hope it will be helpful to the forum administrator when managing the Discuz forum. By flexibly adjusting the display method of the number of people online, we can better meet user needs and improve the operational effects and user experience of the forum.
