Fix the Google Sitemap Generator Plugin for WordPress

     Arne Brachnold’s Google Sitemap Generator for WordPress is a pretty neat piece of software that’ll build a Google-style XML-Sitemap, and ping Google with it every time you update your blog.
     Good stuff for SEO, good stuff for making sure Google has your site indexed. 

     After setting up a few blogs with the latest, I found a caveat that just annoyed me to death: you’re in the Admin, but when you manually update the sitemap, it comes back with a blank page. Sure, I know how to work around it, but they guys I’m setting this stuff up for get all huffy about it.
     Pretty quick bug to figure out.  There’s even a nice ticket on Trac (Ticket 604) that I’m unable to post this solution to…
     Line 2463 of sitemap.php is:

<script type=”text/javascript” src=”list-manipulation.js” mce_src=”list-manipulation.js”></script>

     Of course, that doesn’t exist, but if we change it to:

<script type=”text/javascript” src=”../wp-includes/js/list-manipulation-js.php” mce_src=”../wp-includes/js/list-manipulation-js.php”></script>

     …then all is right and good with the world.

     Hopefully, Arne’ll drop this in his next release — and be able to close Ticket 604 on Trac.  😉

[Ed. Note: The text of this article refers to “the latest” WordPress (2.1.x) and version of the plugin for it (3.0xxx).]

     (“Mark, why so much work talk?”  Because it’s easier to work and laugh than to think about things that are bothering me.  And besides, I’ve only rarely spoken about what I actually do for a living, anyway.) 

     A few days ago, Swankpad’s forum got weird.  Something happened and every post title was set to the same value.  Today, I found out for certain that exactly what code modification was causing it.
     Instead of adding code for upgrades and Mods to phpBB, it’s preferable to use a Patch File for software upgrades, and a neat little thing called EasyMOD to add in any future mods.  EasyMOD is great, and generally makes fewer mistakes than going through many thousands of lines of code to make changes (although, an uninstall feature would be nice!).

     There was a new mod called Akismet Spam Butcher for phpBB that I decided to install last week, just for the heck it — too many spammers.  Though the plugin doesn’t actually *do* anything, it was more of a proof-of-concept for using Akismet with phpBB.  I wanted to see how well it worked in adding Spam flags to the database — which is all it does at present.
     (In all honesty, if you can keep people from registering, that alleviates the spam issue altogether.  😉 )

      Anyway … Take a look at this SQL statement, from phpBB with Akismet Spam Butcher added via EasyMOD:

$sql  = ($mode != “editpost”) ? “INSERT INTO ” . TOPICS_TABLE . ” (topic_title, topic_poster, topic_time, forum_id, topic_status, topic_type, topic_vote, topic_spam) VALUES (‘$post_subject’, ” . $userdata[‘user_id’] . “, $current_time, $forum_id, ” . TOPIC_UNLOCKED . “, $topic_type, $topic_vote, $post_spam)” : “UPDATE ” . TOPICS_TABLE . ” SET topic_title = ‘$post_subject’, topic_type = $topic_type ” . (($post_data[‘edit_vote’] || !empty($poll_title)) ? “, topic_vote = ” . $topic_vote : “”) . ” , topic_spam = $post_spamWHERE topic_id = $topic_id”;

     Sometimes it’s just glaringly obvious where the problem is.

     One Edit, and every post in entire bloody forum gets the post title you edited.

     (Hint:  “$topic_spam = 0”)

     *shakes head*

#—–[ IN-LINE FIND ]———————————
# Yes, we’re still working within the same FIND
# Note that the space here is important, you will need to be sure there is
# a space between what’s there and what we’ll add next
#
 WHERE topic_id = $topic_id”;
#
#—–[ IN-LINE BEFORE, ADD ]————————
#
, topic_spam = $post_spam

     Looks like EasyMOD was the culprit… but then again, I probably would’ve done the syntax a little differently due to the spaces.

     Removing the Spam Butcher anyway … I found a more elegant solution. 😉

Simplicity Rules the Day

     Before I start this little rant, I just wanna say, this is not to ridicule Chris — he’s certainly worth his salt.  This was just an example — and a rather basic one, at that, given that this was more of an oversight than a faux pas — of something that’s been getting on my nerves for years.

     Every once in a while, someone’ll do something, semi-cool with a piece of software, but their execution makes it appear that they’ve forgotten why a given function works the way it does.  It happens a lot these days, and I’m glad I’m old enough to remember “why” things are like they are.

     A case in point — and Chris is a brilliant guy, mind you, and again, I’m not bashing him — was the beginnings of a WordPress plugin (blog software, for the initiated) to show extra formatting buttons in the Text Editor.

function st_addAdvanced($buttons) {
    unset($buttons[22]);
    array_push($buttons, ‘wp_adv’);
    return $buttons;
}

     It’s a pretty elegant little function.  It takes an array called $buttons, and changes the last value to ‘wp_adv’ and returns it.  Unfortunately, it makes things look ugly because of the way the $buttons array is used elsewhere in the code.
     He says, “Ahh, there are some formatting issues to take care of.”

     I’ve always had this bizarre K.I.S.S. approach to programming anyway.  I mean, hey, why bother calling two other functions, unset() and array_push() when I can do what I need with a single, local variable?

function st_addAdvanced($buttons) {
    $x=$buttons[21];
    $buttons[21]=’wp_adv’;
    $buttons[22]=$x;
    return $buttons;
}

     Sure, I could’ve used two, and said, “$a=$buttons; $x=a[21]; $a[21]=’wp_adv’; $a[22]=$x; return $buttons;” to save keystrokes…. but… I’d be wasting as much memory as I gained CPU by foregoing the functions.

     But that’s basically my argument about most Developers these days.  It’s a pretty serious can of worms for me to open, because I know I’ll have developers coming from all over to tell me I’m full of it…  Even though I was writing Assembler before their parents ever met, and have some pretty cool — working, useful, debugged — software under my belt…. Joke ’em if they can’t take a f… *shh*

     Seriously, it’s no wonder our CPU and Memory requirements are so ridiculously high these days.  There’s an API or a DLL or a Library for freaking everything!  Layers upon layers, upon more layers, with repositories and snippets and widgets and scripts galore!

     Our Universities teach this method, often telling people, “Do it this way!” without telling people “Why it should be done this way.”  The “simpler” things get, the more abstract they become.
     They’re not churning out programmers and problem solvers.  They’re churning out memorize-and-regurgitate linkers who can’t write code without the assistance of a Visual Integrated Development Environment.

     Hey … Wasn’t the whole point of all this Link Library, Visual garbage to make software development easier?  Faster?  More bug free?

     I used to sit down with vi, edit or Notepad and it’d take me a couple of days to write a program.

     I can use all these neato-keen, new-fangled hooks and VIDEs, and it’ll still take me a couple of days to write a program…
     But it might take weeks to debug.

     Most developers do the same thing… And spend a lot of time setting up their VIDE.  Or getting a bit of code they copied off the internet to work.  Or…

     But, hey … I’m probably full of it, right?

     As employers, educators and policy makers, we need to get back to basics.  Yes, teach how.  But teach why, as well.
