Hi Janet,
Thank you 🙂

If we change this line
https://github.com/buddydev/link-page-to-groups/blob/master/link-page-to-groups.php#L77

echo '<li class="bp-linked-group-page"><a href="' . get_permalink( $post ) .'">'. get_the_title( $post ).'</a></li>';

to

echo '<li class="bp-linked-group-page"><a href="' . get_permalink( $post ) .'" target="_blank">'. get_the_title( $post ).'</a></li>';

That will always open the link in new tab on click.
Hope that helps.

Hi Zsuzsa,
Thank you. It might be due to some other conflicts. I do plan to add a warning in future when there are duplicate slugs to avoid the issue.

Thank you for marking it as resolved.

Best Regards

No problem. I am glad It finally worked. I wish there was a way to filter email notification link.

That simply means that your theme is not styling it. It should be there if you check the source. You will need to style it to look like the unordered list using css.

Please use the following code instead.

/**
 * Remove groups from user profile based on member type.
 */
function buddydev_remove_group_based_on_member_types() {
	if ( ! bp_is_user() ) {
		return;
	}

	$user_id = bp_displayed_user_id();

	if ( ! bp_has_member_type( $user_id, 'agent' ) ) {
		bp_core_remove_nav_item( 'groups' );

		$access = bp_core_can_edit_settings();
		$friends_link = bp_displayed_user_domain()? bp_displayed_user_domain() : bp_loggedin_user_domain();
		$friends_link = trailingslashit( $friends_link . bp_get_friends_slug() );
		bp_core_new_subnav_item(array(
			'name'            => __( 'Invitations', 'buddypress' ),
			'slug'            => 'invites',
			'parent_url'      => $friends_link,
			'parent_slug'     => bp_get_friends_slug(),
			'screen_function' => 'buddydev_groups_screen_group_invites',
			'user_has_access' => $access,
			'position'        => 30
		));
		// move the invitations to the friends screen.
	}
}

add_action( 'bp_setup_nav', 'buddydev_remove_group_based_on_member_types', 1001 );

/**
 * Helps us detect screen.
 */
function buddydev_groups_screen_group_invites() {
    add_action( 'groups_screen_group_invites', 'buddydev_load_invite_template' );
	groups_screen_group_invites();
}

/**
 * Load our template.
 */
function buddydev_load_invite_template() {
    add_action( 'bp_template_content', function () {
        bp_get_template_part('members/single/groups/invites');
    });

	bp_core_load_template('members/single/plugins' );
}

/**
 * Change the invite link url for the non 'agent' users.
 *
 * @param string $link original link.
 *
 * @return string
 */
function buddydev_update_group_invite_link( $link ) {
    // for agent, do not break it.
    if ( bp_has_member_type( bp_loggedin_user_id(), 'agent' ) ) {
       return $link;
    }

	global $groups_template;

	if ( empty( $group ) ) {
		$group =& $groups_template->group;
	}

	$friends_url = bp_loggedin_user_domain() . bp_get_friends_slug() .'/invites/';
	$url         = trailingslashit( $friends_url . 'accept/' . $group->id );
	$url         = add_query_arg( array( 'redirect_to' => $friends_url  ), $url );

	//
	return wp_nonce_url( $url, 'groups_accept_invite' );
}

add_filter( 'bp_get_group_accept_invite_link', 'buddydev_update_group_invite_link' );

/**
 * Change the reject link url for the non 'agent' users.
 *
 * @param string $link original link.
 *
 * @return string
 */
function buddydev_update_group_reject_link( $link ) {
    // for agent, do not break it.
    if ( bp_has_member_type( bp_loggedin_user_id(), 'agent' ) ) {
       return $link;
    }

	global $groups_template;

	if ( empty( $group ) ) {
		$group =& $groups_template->group;
	}

	$friends_url = bp_loggedin_user_domain() . bp_get_friends_slug() .'/invites/';
	$url         = trailingslashit( $friends_url . 'reject/' . $group->id );
	$url         = add_query_arg( array( 'redirect_to' => $friends_url ), $url );

	return wp_nonce_url( $url, 'groups_reject_invite' ) ;
}

add_filter( 'bp_get_group_reject_invite_link', 'buddydev_update_group_reject_link' );

/**
 * Remove groups from adminbar based on member type.
 *
 * @param array $nav nav items.
 *
 * @return array
 */
function buddydev_filter_show_hide_groups_in_adminbar( $nav ) {
	if ( ! is_user_logged_in() ) {
		return $nav;
	}

	if ( ! bp_has_member_type( bp_loggedin_user_id(), 'agent' ) ) {
		$nav = array();
	}

	return $nav;
}

add_filter( 'bp_groups_admin_nav', 'buddydev_filter_show_hide_groups_in_adminbar' );

It will work if you try to accept from the Friends->Invites screen.

Problem:-
– I don’t see a way for filtering the link in the email notification.
– You also need code for filtering the link in the local notification(atleast 2 more filters).
