How to implement display and access permission management for paid content or member-only content?

In today's content economy era, many websites hope to achieve value monetization and enhance user stickiness by providing paid or exclusive member content.AnQiCMS (AnQiCMS) fully understands this need, and from the very beginning of system design, it has integrated a powerful user group management and VIP system, providing flexible and efficient solutions for webmasters to implement content classification and permission control.

To implement the display and access permission management of paid content or member exclusive content, we mainly need to complete two things: one isDefine the access level when the content is published, the other isIn the front-end template, dynamically judge and display content based on the user's membership level.

Foundation: User group and VIP system

The core of AnQi CMS for implementing content permission management lies in its 'User Group Management and VIP System'.This system allows you to create different user groups and define different permission levels for each group.For example, you can set groups such as "General Member", "Senior Member", and "VIP Member", and assign levels 0, 1, 2, 3, and so on in numerical form to them, with higher numbers representing higher levels.This hierarchical mechanism lays the foundation for the fine management of content.

Content preparation: Label exclusive content

In AnQi CMS, defining access levels for content is not complicated.When you publish or edit documents in the background, in addition to filling in the usual information such as title and content, Anqi CMS provides the function of 'content model custom fields'.After enabling the "User Group Management and VIP System", you can add a custom field in the content model, such as naming it "Reading Level" (ReadLevel), and setting it as a numeric type.

When editing each piece of content, you can specify the required 'reading level' value for this content.For example, a public content can be set to level 0, while a VIP exclusive content can be set to level 1 or higher.AnQi CMS'sarchiveDetailBuilt-in tags,ReadLevelField, this makes it very convenient to set and call content-level settings. This way, each piece of content has a clear access threshold.

Template control: to achieve dynamic display of content.

After completing the content level settings, the next step is to control the display of content through logical judgments in the front-end template. The Anqi CMS template engine supports a variety of logical judgment tags, especiallyif/userDetailanduserGroupDetailThese tags are the key to implementing dynamic content display.

Generally, you will perform permission judgment in the template file of the content detail page (such as){模型table}/detail.html). Its basic idea is:

1. Get the reading level required for the current document.
2. Determine the login status of the current visiting user.
3. If the user is logged in, get the level of the user group they belong to.
4. Compare the user level with the content required level to decide whether to display the full content, prompt information, or login registration guidance.

Here, we assume that the template can be accessed in some way (such as system-wide global variablescurrent_user_logged_inindicating the login status, as well as `current_
