Limiting BuddyPress Activity Posting by User Role with Daily and Weekly Limits

Purpose

This code snippet is designed to limit the number of activity posts that users can make in BuddyPress based on their roles. It allows you to set daily and weekly limits on how many posts a user can make.

How It Works

The snippet performs the following tasks:

• Restricts activity posting: Users can only post a certain number of activity updates per day and week, which can be configured via the code.
• Hides the post form: Once the user has reached their limit, the “What’s New” form is hidden, and a notification is displayed.

How to Use

1. Add the Code Snippet:
   • Copy the following code and add it to your theme’s functions.php file or use a custom functionality plugin to apply this to your WordPress/BuddyPress site.

/**
 * Hide BuddyPress Activity Post form based on daily and weekly limits.
 */

    if ( 'activity/post-form' != $slug ) {

        $user_role                     = $current_user->roles;
        $user_id                       = get_current_user_id();

        // Check if role has activity form restriction
        if ( ! empty( $user_role ) ) {
            foreach ( $user_role as $role ) {
                $activity = ( ! empty( $blpro_membership_restrictions[ $role ]['activity'] ) ) ? $blpro_membership_restrictions[ $role ]['activity'] : array();

                $post_count = blpro_get_user_activity_count( $user_id );

                $daily_limit = 10;
