Appoint members that visit regularly: Your moderators should be around your community on a regular basis so that their assigned forums are properly maintained. I ll leave it to you to define regular basis. Limit moderators to one or two forums at first: It s tempting to create supermoderator positions moderators who control every forum and give every moderator free reign. However, especially in the formative stages of your community when you may or may not know your staff members well, you will want to keep moderators limited to one or two forums. They will not be able to use their powers outside those forums, and that s an important step in securing your forums. Keep supermoderators to a minimum: If you wish to create supermoderator positions, with power over all forums, appoint just enough (one or two is usually plenty, but that can vary depending on traffic) to provide backup to existing moderators. Ideally, you should appoint supermoderators only when your board s traffic increases to the point where you need a couple people to back up the moderators. Use extreme caution when appointing additional administrators: As your board grows and the administrative tasks increase, you won t have a choice but to add another administrator or two. Appoint someone who you can trust and have worked with (preferably a moderator). Administrators should have enough technical savvy to operate the board s controls, know how to fix problems, and know how to avoid problems. Administrators should also know how to put on a good public face, as they will likely be contacted often by new members who may be unfamiliar with the phpBB software. (I consider prior experience with the board software a major plus in an administrator.)

Keeping an eye on who is permitted to do what is incredibly important. Sadly, phpBB 2.0 does not contain an easy way to audit the number of people with administrator or moderator rights. I typically resort to periodically running two simple SQL queries using the phpMyAdmin front end to MySQL. Here, I ll explain how to run those queries.

Widgets are the building blocks of WordPress sidebars. They can be created in a theme s functions file or in a plugin. In this chapter, I ll show you how I created two of my plugins, Recent Posts From Category and Dashboard Notepad. You ll see how to create these widgets as part of a theme s functions file, and in the next chapter I ll show you how to transform them into plugins. While these two plugins create widgets, note that plugins can do any number of other things. Widgets are limited to displaying a bit of content inside the widget areas you defined in your theme s functions.php file back in chapter 6.

Note Contact your hosting provider to determine the location of phpMyAdmin on the server, as this

When you have phpMyAdmin open, select the database you created for phpBB (when you installed phpBB, as described in 8) by clicking the name of the database in the left pane. This will load a listing of this database s tables in the main area of the window. Newer versions of phpMyAdmin (which most hosts run) have a SQL tab just above the area where the tables of the database are listed. Click that tab, and you ll be presented with a SQL query box, which should resemble Figure 10-1.

WordPress widgets are classes, which makes them easy to duplicate, even if you ve never worked with object-oriented programming before. A class provides a blueprint for objects that will be reused in various ways. Creating a new widget is a matter of copying the basic widget class, then adjusting the enclosed functions to output the content you have in mind. The widget class contains four functions: one that registers the widget, one that prints the widget output, one that updates the widget options, and one that displays the options form.

You ll input a raw SQL query here. In the query box, type the following line to check who has administrator rights, substituting <yourprefix> with the database prefix you selected while setting up your phpBB (typically phpbb): SELECT user_id, username FROM <yourprefix>_users WHERE user_level = 1 To check to see which users have moderator permissions, run this query: SELECT user_id, username FROM <yourprefix>_users WHERE user_level = 2 The queries return the user ID number assigned by phpBB at registration and the username of the empowered users, in a table structured like the one shown in Figure 10-2.

If you find SQL queries cumbersome and inconvenient, as most people do, a far more graceful alterTip

Before I go into the details of custom widgets, let s take a look at the code for one of the simplest built-in widgets, the calendar (Figure 8-1). The code (from wp-includes/default-widgets.php) is given in Listing 8-1. Things you would change in your own widget are in bold.

native to running these queries exists as a modification to the board. Visit http://www.phpbbhacks.com/ download/2977 to download the feature, and flip ahead to 11 for pointers on installing it.

Auditing on a regular basis is a good method for detecting people who may have surreptitiously gained administrative or moderator access without your knowledge. If you find people who are administrators that you don t want as administrators, you can edit their permissions (see the Setting Per-User Permissions section later in this chapter) and remove their rights. Then be sure to read the Installing Updates section, coming up soon, as you may have a security flaw.
