I also noticed after the update that one of my client sites wasn’t working correctly. It turns out there’s a bug in WordPress 3.1 which breaks category exclusion. On my client’s site, I was using this code:

function exclude_category($query) {
$cat_id = '-'.get_cat_id('meetings');
if ( $query->is_home ) {
$query->set('cat', $cat_id);
}
return $query;
}
add_filter('pre_get_posts', 'exclude_category');

Fortunately that bug I linked to also includes a workaround. By changing the above bit of code to read as follows, I was able to fix my client’s site. ^_^

function exclude_category($query) {
$cat_id = '-'.get_cat_id('meetings');
if ( $query->is_home ) {
$query->set('category__not_in', array($cat_id));
}
return $query;
}
add_filter('pre_get_posts', 'exclude_category');

	if ( $options['menuLayout'] == NR_MENU_SINGLE ) {

		add_menu_page('Now Reading', 'Now Reading', 9, 'admin.php?page=add_book', 'now_reading_add');

		add_submenu_page('admin.php?page=add_book', 'Add a Book', 'Add a Book',$nr_level , 'add_book', 'now_reading_add');

		add_submenu_page('admin.php?page=add_book', 'Manage Books', 'Manage Books', $nr_level, 'manage_books', 'nr_manage');

		add_submenu_page('admin.php?page=add_book', 'Options', 'Options', 9, 'nr_options', 'nr_options');

To read like this:

	if ( $options['menuLayout'] == NR_MENU_SINGLE ) {

		add_menu_page('Now Reading', 'Now Reading', 9, 'add_book', 'now_reading_add');

		add_submenu_page('add_book', 'Add a Book', 'Add a Book',$nr_level , 'add_book', 'now_reading_add');
		add_submenu_page('add_book', 'Manage Books', 'Manage Books', $nr_level, 'manage_books', 'nr_manage');
		add_submenu_page('add_book', 'Options', 'Options', 9, 'nr_options', 'nr_options');

Then Now-Reading’s single admin menu worked properly again.

I’ve disabled the most likely culprit and now am writing this post to see if I’m right about which plugin is causing the problem.  Wish me luck.

Side note: Our snowblower stopped working during the last snow-storm.  The engine runs, but the auger stopped turning.  This weekend we got a bunch more snow, so I opened up the snowblower, figured out what the problem was and fixed it.  I fought the snowblower and I won!  :)  Unfortunately while troubleshooting it, I also fought my vice-grips and the vice-grips won (I’ve got the blood blister and cuts to prove it).

UPDATE: My first guess was wrong but I’ve figured out which plugin is causing the problem and deactivated it. For the record, Referrer Detector & LiveJournal Crossposter do not play nice together.

Testing… 1… © Mark McKibben, Creative Commons Attribution-NonCommercial-ShareAlike 3.0 United States.

// Now-Reading Plugin: Get the display name of the book's reader
function mlm_book_reader( $echo=true ) {
	global $book;

	$user_info = get_userdata($book->reader);

	if ( $echo )
		echo $user_info->display_name;
	return $user_info->display_name;

}

This grabs “Display name publicly as” from the user’s profile and displays it on the page. I put the function in the functions.php file of the theme I’m using (so any automatic upgrades of the plugin won’t erase it). Then I put < ?php mlm_book_reader() ?> into my custom single.php template and viola!

Note: this has only been tested on WordPress 2.6.2 with Now-Reading 4.4.3.

• I borrowed this book fromlibrary

When they should simply have a line reading “I borrowed this book from my local library”. I had spent much
time fiddling with my templates trying to figure out how the upgrade broke them and today I figured it out. The truth is my template was just fine. The problem is the newer version of Now-Reading was applying a new filter to book-meta¹. That filter is wpautop and it was wrapping my variable in <p> … </p> tags. Those tags screwed up the display and made my variable checks fail. To correct the problem, I went into now-reading/default-filters.php and commented out add_filter('book_meta_val', 'wpautop');. Now my single book pages look like they’re supposed to again. Yeah!

¹ This is a custom field available in the back-end of the plugin and it is where I store the information telling my template if I borrowed the book and from whom I borrowed it.

I looked at the code Rob used and with a little help from the Practical PHP I hacked together my own function based on Rob’s. By default print_reader2 works the exactly the same as print_reader¹ but by feeding it an additional parameter, you get your choice of what to use to display as reader’s name:

• 0: Prints out the user_login aka the username you use to log into WordPress.
• 1: Prints user_nicename, appears to simply be an all lower case version of the user’s nickname².
• 2: Prints display_name, from the “Display name publicly as” field in your WordPress profile.
• 3: Prints first_name, from the “First name” field in your WordPress profile.
• 4: Prints nickname, from the “Nickname” field in your WordPress profile.

function print_reader2( $echo=true, $reader_id = 0, $display = 0 ) {
	global $userdata;

	$username='';

	switch($display) {
		case "1": if (!$reader_id) { get_currentuserinfo(); $username = $userdata->user_nicename; } else { $user_info = get_userdata($reader_id); $username = $user_info->user_nicename; }; break;
		case "2": if (!$reader_id) { get_currentuserinfo(); $username = $userdata->display_name; } else { $user_info = get_userdata($reader_id); $username = $user_info->display_name; }; break;
		case "3": if (!$reader_id) { get_currentuserinfo(); $username = $userdata->first_name; } else { $user_info = get_userdata($reader_id); $username = $user_info->first_name; }; break;
		case "4": if (!$reader_id) { get_currentuserinfo(); $username = $userdata->nickname; } else { $user_info = get_userdata($reader_id); $username = $user_info->nickname; }; break;
		default: if (!$reader_id) { get_currentuserinfo(); $username = $userdata->user_login; } else { $user_info = get_userdata($reader_id); $username = $user_info->user_login;};
   }
	if ($echo)
		echo $username;
	return $username;
}

Side note: WordPress 2.5.1 got released today and it includes a security fix, be sure to update your blogs!

¹ At least, I think it does. I’m not a programmer and I only know enough PHP to be dangerous to myself.
² The WordPress Codex does not appear to define what this field is used for or why it exists, so that’s just my guess.

I thought it only fair to share my hacks, so enjoy or not as you choose. I’m sure there’s a more elegant way to code these changes, but I am not a programmer so if you use these and don’t like how I changed them… Well, you just have to suffer then. :p Feel free to ask questions but keep in mind:

• I’m not a programmer.
• These plugins aren’t originally mine. I don’t know much about how they work. I only know enough to hack together my changes.
• If my hacked versions don’t work for you, try the originals before asking me for help. The people who made the originals should have a better idea of why things work/don’t work.
