While working on a new site design, I found an interesting bug in WordPress 2.7. I created two new pages to use as “Front page displays”, one called Blog and one called Home. To create the pages, I clicked on Pages > Add New, entered a Title and clicked Publish.

I then went to my Reading Settings (Settings > Reading) and set the static Front and Posts page to the pages I just created. Going back to my site, I tested out the new static pages only to find they didn’t work.

After being asked to help get the SimpleModal Contact Form demo running on a Drupal powered site, I decided to try and turn it into a Drupal Module. Based on my SimpleModal Contact Form (SMCF) WordPress Plugin, I was able to create something which I think is now ready for a beta release.

The details can be found on the project page. The module was built for Drupal 6.x, so give it a try and let me know if you find any issues.

After more helpful input, I’ve decided to update my original solution.

Instead of overriding four WordPress functions and adding two new ones in my functions.php file, I have slimmed it down to just one:

/**
 * If more than one page exists, return TRUE.
 */
function show_posts_nav() {
	global $wp_query;
	return ($wp_query->max_num_pages > 1);
}

This function will tell me if there is more than one page…and if there is, I will show the posts navigation (next_posts_link and previous_posts_link). I updated my WordPress (index.php, archives.php and search.php) files with:

<?php if (show_posts_nav()) : ?>
<div class='navigation'>
	<span class='older'><?php next_posts_link('&laquo; Older Entries'); ?></span>
	<span class='newer'><?php previous_posts_link('Newer Entries &raquo;'); ?></span>
</div>
<?php endif; ?>

As for the single post next/previous links, I decided to remove the check because I’ll always have more than one entry.

Much cleaner and less code

While creating a new theme for this site, I added some CSS styling around the page/post navigation links.

For example, in my index.php page, I have the following HTML/WordPress code:

<div class='navigation'>
  <span class='older'><?php next_posts_link('&laquo; Older Entries') ?></span>
  <span class='newer'><?php previous_posts_link('Newer Entries &raquo;') ?></span>
</div>

And the following CSS code:

.navigation {font-size:.7em; background:#353535; height:16px; margin:0 -16px 8px -16px; padding:8px 6px 0px;}
.navigation span {margin-top:-4px;}
.navigation .older {float:left;}
.navigation .newer {float:right;}

Everything looked great, until I brought up a page that did not have a previous or next link. The styled navigation div was still there, but there was nothing in it. So, I set out to conditionally display the navigation div if either a previous or next link existed.

I was trying to add PHP Zip support on my cPanel server today and when Apache went to restart, it failed with the folowing error:

Cannot load /usr/local/apache/libexec/mod_bwlimited.so into server: /usr/local/apache/libexec/mod_bwlimited.so: cannot open shared object file: No such file or directory

After a Google search, I found that I needed to run:

cd /usr/local/cpanel/apache

/usr/local/apache/bin/apxs -iac mod_auth_passthrough.c
/usr/local/apache/bin/apxs -iac mod_bwlimited.c
/usr/local/apache/bin/apxs -iac mod_log_bytes.c

I was able to start Apache afterwards and everything is back to normal…

When I changed jobs, my commute changed from mostly surface streets to mostly highway. I-80 is notoriously congested and I wanted to strategically plan my commute to avoid as much traffic as possible.

I started by watching traffic online and then found Traffic.com, where I could create custom drives and receive alerts, etc. Pretty cool…but I wanted a way to SEE traffic trends, so I designed a way to get data from Traffic.com and to then display that data in a graph.

Traffic.com offers a RSS feed, so my plan was to use data from that feed to generate the graphs. So, I signed up at Traffic.com and created two custom drives; “Home to Work” and “Work to Home”. Next I created a database and tables to hold the data:

I stumbled upon a PHP framework called Kohana, which is based on CodeIgniter. I’ve used CI a bit in the past and thought I’d give Kohana a whirl. I downloaded the latest code and tried to run it on a Windows XP machine.

Well, when I brought up the site, I got an error:

Fatal error: Unable to locate the requested file, log.php in <system_path>/system/core/Kohana.php on line 408

After a lot of digging, I found that there was a glob() call that was not behaving correctly. I narrowed it down to what I believe to be a bug in PHP with the glob() function, using the GLOB_BRACE flag, and using a pattern that includes a colon (as in {c:/firstFolderToCheck,c:/secondFolderToCheck}).

Assuming it turns out to be valid, I’m surprised that it hasn’t been found/reported before…
