為BuddyPress中的特定用戶角色啟用組創建

Question

BuddyPress提供“ bp_user_can_create_groups”過濾器，以限制用戶創建組的能力。 參考-http://wordpress.org/support/topic/restrictallow-group-creation-by-user-role?replies =3# post - 4617184和http://etivite.com/api-hooks/buddypress/trigger/ apply_filters / bp_user_can_create_groups /

如何使用此過濾器限制BuddyPress中特定用戶角色的組創建？ 目前，只允許管理員創建組，而我也不想允許每個用戶都可以創建組。

我已將以下代碼添加到bp-custom.php中，但無法正常工作

function create_groups1( $can_create, $restricted=false ) {
// maybe we don't want to override if it's restricted?
if ( ! $restricted ){
    // get the logged in user's ID
    $user_ID = get_current_user_id();
    // some logic to determine if the current user can create a group
    $user1 = new WP_User( $user_ID );

    if ( !empty( $user1->roles ) && is_array( $user1->roles ) ) {
            $r=$user1->roles[0];
    }
    if (current_user_can('read')) {
        $r="subscriber";
    }
    if ( $r == "subscriber" || $r == "participant" ){
        // we will return this allowing them to create groups
        $can_create = true;
    }
}
return $can_create;
}
add_filter( 'bp_user_can_create_groups', 'create_groups1', 10, 2 );

您需要編寫一個函數並將其附加到“ bp_user_can_create_groups”掛鈎。 在函數內部，確定您是否希望當前用戶能夠創建組並相應地返回$can_create 。

function bp_user_can_create_groups( $can_create, $restricted=false ){
    // maybe we don't want to override if it's restricted?
    if ( ! $restricted ){
        // get the logged in user's ID
        $user_ID = get_current_user_id();
        // some logic to determine if the current user can create a group
        if ( user_can_create_group( $user_ID ) ){
            // we will return this allowing them to create groups
            $can_create = true;
        }
    }
    return $can_create;
}
add_filter( 'bp_user_can_create_groups', 'bp_user_can_create_groups', 10, 2 );
