Comprehensive Reference for WordPress No-Nofollow/Dofollow Plugins

In this article, I present a concise, current, and comprehensive reference for WordPress no-nofollow and dofollow plugins. Every attempt has been made to provide accurate, useful, and complete information for each of the plugins represented below. Further, as this subject is a newfound interest of mine, it is my intention to keep […] Continue reading »
Eliminate 404 Errors for PHP Functions
Recently, I discussed the suspicious behavior recently observed by the Yahoo! Slurp crawler. As revealed by the site’s closely watched 404-error logs, Yahoo! had been requesting a series of nonexistent resources. Although a majority of the 404 errors were exclusive to the Slurp crawler, there were several instances of requests that were also coming from Google, Live, and even Ask. Initially, these distinct errors were misdiagnosed as existing URLs appended with various JavaScript functions. Here are a few typical examples […] Continue reading »
Suspicious Behavior from Yahoo! Slurp Crawler
Most of the time, when I catch scumbags attempting to spam, scrape, leech, or otherwise hack my site, I stitch up a new voodoo doll and let the cursing begin. No, seriously, I just blacklist the idiots. I don’t need their traffic, and so I don’t even blink while slamming the doors in their faces. Of course, this policy presents a bit of a dilemma when the culprit is one of the four major search engines. Slamming the door on […] Continue reading »

Temporary Site Redirect for Visitors during Site Updates
In our article Stupid htaccess Tricks, we present the htaccess code required for redirecting visitors temporarily during periods of site maintenance. Although the article provides everything needed to implement the temporary redirect, I think readers would benefit from a more thorough examination of the process — nothing too serious, just enough to get it right. After discussing temporary redirects via htaccess, I’ll also explain how to accomplish the same thing using only a small slice of PHP. It’s like two […] Continue reading »
MySQL Magic: Find and Replace Data
Recently, I needed to find and replace all instances of “http://website” in the wp_comments table of the WordPress database. Fortunately, SQL provides a simple way to find and replace data with its wonderful UPDATE function. Continue reading »
Another Mystery Solved..
Recently, after researching comment links for an upcoming article, I realized that my default <input /> values were being submitted as the URL for all comments left without associated website information. During the most recent site redesign, I made the mistake of doing this in comments.php: … <input class="input" name="url" id="url" value="[website]" onfocus="this.select();" type="text" tabindex="3" size="44" maxlength="133" alt="website" /> … Notice the value="[website]" attribute? It seemed like a good idea at the time — I even threw in a nice […] Continue reading »
WP-ShortStat Slowing Down Root Index Pages
For over a year now, I have been using Markus Kämmerer’s (Happy Arts Blog) WP-ShortStat plugin for WordPress. The plugin is relatively well-maintained and remains one of my favorite admin tools. Great for popping in on stats without logging into Mint. Nonetheless, due to its IP/country-detection functionality, WP-ShortStat has experienced its share of difficulties (e.g., read through the change log on the plugin’s home page). In this article, I describe how WP-Shortstat slows down the root index-page of a site, […] Continue reading »
How to Block IP Addresses with PHP
Figuratively speaking, hunting down and killing spammers, scrapers, and other online scum remains one of our favorite pursuits. Once we have determined that a particular IP address is worthy of banishment, we generally invoke the magical powers of htaccess to lock the gates. When htaccess is not available, we may summon the versatile functionality of PHP to get the job done. This method is straightforward. Simply edit, copy and paste the following code example into the top of any PHP […] Continue reading »
Use PHP to Create Symbolic Links without Shell Access
On Unix systems, a symbolic link refers to a file that points to another file or directory. Symbolic links serve as powerful tools for web designers and developers. Using shell access, creating a symbolic link requires only one line of code: ln -s /home/username/public_html/directory1 /home/username/public_html/directory2 Simple enough. Assuming you have access to the linux shell. Unfortunately, many shared hosting environments deny shell access. Fortunately, creating symbolic links — also called “symlinks” — remains a possibility via the PHP symlink() function. […] Continue reading »
Compressed JavaScript Compression
In this article, we extrapolate our favorite CSS-compression technique for JavaScript. Below, we outline the steps required to auto-compress your JavaScript documents via gzip and PHP. Two different compression methods are presented. The first method does not require htaccess, but rather involves the manual editing of JavaScript files. The second method employs htaccess to do all the work for you, thus requiring much less effort to implement. In either case, the result is the same: automatically compressed content delivered only […] Continue reading »

Automatic Language Translation Methods
As you may have noticed, Perishable Press recently added automatic language translation to each of our articles. The free, automatic translations are available as a series of image links (via corresponding country flag icons) next to each article’s individual post view. We have found that providing this free service is important as many of our visitors come from countries other than the United States, and therefore may be unable to read our articles as presented in the English language.

Triple Loop for WordPress
Two of the themes developed by Perishable Press, Apathy and Information, depend on three WordPress loops to operate as intended. For each of these themes, the three loops consist of two “side” loops and one main loop. The side loops each display posts from one specific category, while the main loop displays posts from every category not specified in the side loops. Continue reading »
