Introduction

Content Access Control

Access restrictions on posts

On posts an pages (and custom content types) a new meta box titles Access restrictions appears. By checking Enforce read access, you can restrict access to the post to groups and users who have the groups_read_post capability. You need to assign this capability to a group and make users members of that group to allow them to see those posts.

Content visibility for members and non-members

The [groups_member] and [groups_non_member] shortcodes are used to limit visibility of content to users who are members of a group or users who are not members of a group. Multiple comma-separated groups can be specified.

Example: Limiting visibility of enclosed content to registered users.

[groups_member group="Registered"]

Only registered users can see this text.

[/groups_member]

Content visibility based on capabilities

The [groups_can] and [groups_can_not] shortcodes limit visibility of enclosed content to those users who have the capability or those who do not have it. Multiple capabilities can be given.

Example: Showing enclosed content to users who can edit_posts (standard WordPress capability).

[groups_can capability="edit_posts"]

You can see this only if you have the edit_posts capability.

[/groups_can]

Integration in the 'Users' menu:

Users - group membership is managed from the standard Users admin view. Users are automatically added to the Registered group. You can add multiple users to other groups here and also remove them.

Sections in the 'Groups' menu:

Groups

Here you can:

• add groups
• remove groups
• assign capabilities to groups

Capabilities

This is where you add, remove and manage capabilities.

Capabilities can be assigned to groups and users (1). These capabilities include the standard WordPress capabilities but you can also define additional capabilities for your web-application.

Groups defines some capabilities of its own. The groups_read_post capability is used to restrict access to certain posts or pages to groups (and users) with that capability only.

(1) Assigning capabilities to users is not integrated in the user interface yet but can be done through API calls.

Options

Administrator override

Administrator overrides can be turned off.

Permissions

For each role these permissions can be set:

• Access Groups: see information related to Groups.
• Administer Groups: complete control over everything related to Groups.
• Administer Groups plugin options: grants access to make changes on the Groups > Options admin section.

Testing the plugin

A convenient option is provided to delete all data that has been stored by the Groups plugin. This option is useful if you just need to start from fresh after you have been testing the plugin.

Shortcodes

Limit content visibility

These shortcodes are used to limit the visibility of the content they enclose:

• [groups_member]
• [groups_non_member]
• [groups_can]
• [groups_can_not]

See above for examples and descriptions.

Show group information

• [groups_group_info]

This shortcode takes the following attributes to show information about a group:

• group : (required) the group ID or name
• show : (required) what to show, accepted values are: name, description, count
• single : (optional) used when show="count" and there is 1 member in the group
• plural : (optional) used when show="count" and there is more than 1 member in the group, must contain %d to show the number of members

Examples:

• [groups_group_info group="Registered" show="count"]

• There [groups_group_info group="1" show="count" single="is one member" plural="are %d members"] in the [groups_group_info group="1" show="name"] group.
