3 Ways to Exclude Content from WordPress Feeds

[ Exclude Feed Content ]

This may surprise you, but I post quite a bit of content that never appears in the site’s main feed. It is my impression that a vast majority of subscribers are interested in web/graphic-design and development-related topics, and are really much less interested (if at all) in the miscellaneous odds and ends that wind up in the ever-expanding Perishable Press database. In the past, the process of excluding content from the main feed typically involved changing the post-date to something […] Continue reading »

WordPress Tip: Quick Hack to Block Spam for the Wordspew Shoutbox Chat Plugin

Recently, I reactivated an older version (1.16) of Jalenack’s Wordspew Shoutbox plugin for the Dead Letter Art Chat Forum. The DLa collective has been working on a new issue of their ‘zine and needed an easy online chat location for impromptu business dealz (ideas, planning, etc.). Almost immediately after reactivating the Shoutbox plugin, the chat forum was flooded with an endless wave of spam. The rate and volume of spam was so high as to render the forum utterly useless.

WordPress Tip: Careful with that Autosave, Eugene

[ Screenshot: WordPress Autosave Message (Saved at 2:34:02.) ]

After upgrading WordPress from version 2.0.5 to 2.3.3, I did some experimenting with the “post autosave” feature. The autosave feature uses some crafty ajax to automagically save your post every 2 minutes (120 seconds by default). Below the post-editing field, you will notice a line of text that displays the time of the most recent autosave, similar to the following: Continue reading »

WordPress Tip: Remove Spam from the Comment Subscription Manager

[ Image: Jonny Quest (Inverted) ]

After investigating some unusual 404 errors the other day, I found myself digging through the WordPress Admin Area trying to locate the “Subscribe to Comments” options panel. As it turns out, administrative options for the Subscribe to Comments plugin are split into two different areas. First, the S2C plugin provides configuration options under the WordPress General Settings > “Subscribe to Comments”, which enables users to tweak everything from subscription messages to custom CSS styles. New to me was the other […] Continue reading »

What is My WordPress Feed URL?

[ WordPress RSS Feed ]

For future reference, this article covers each of the many ways to access your WordPress-generated feeds1. Several different URL formats are available for the various types of WordPress feeds — posts, comments, and categories — for both permalink and default URL structures. For each example, replace “http://example.com/” with the URL of your blog. Note: even though your blog’s main feed is accessible through many different URLs, there are clear benefits to using a single, consistent feed URL throughout your site. […] Continue reading »

WordPress Discussion Management: Enable or Disable Comments and Pingbacks via SQL

Continuing my quest to stop comment spam without using plugins, I have decided to disable comments on “old” posts. In my experience, over 90% of comment, trackback and pingback spam occurs on posts that have been online for over a month or so, just long enough to be indexed by the search engines and picked up by spammers. Especially for older posts that have managed to acquire a little page rank, the frequency of spam attempts is far greater than […] Continue reading »

Quickly Disable or Enable All WordPress Plugins via the Database

[ The Flash ]

Recently, while dealing with the dreaded white screen of death, I found myself unable to login to the WordPress Admin area to manually disable all of the plugins used here at Perishable Press. In the past, I have dealt with this situation by simply deleting all plugin files from the server, however this time, time was of the essence — I had only a few minutes with which to troubleshoot, diagnose, and ultimately resolve the deadly white-screen syndrome. Fortunately, after […] Continue reading »

WordPress Plugins: Transfer Autometa Data to All in One SEO

During my last redesign and site overhaul, I finally made the leap from WP 2.0 to 2.3. In the process of synchronizing data and removing unecessary plugins, I managed to replace several keyword- and meta-related plugins with the incredible All in One SEO Pack (AiOSEO). One of the plugins replaced by AiOSEO is Autometa, an otherwise very useful meta-keywords management tool. With AiOSEO installed, there is no need for Autometa. Over the course of a year or so, Autometa had […] Continue reading »

[ Graphic: Inverted Triangular Fractal ]

Recently, reader Luke Knowles asked how to customize the sort order of his posts in WordPress. Looking into a solution to this question proved quite enlightening. Within moments I was able to discern 4 methods for modifying post order, and then several days later I discovered 2 additional custom sorting techniques. After updating the reply to Luke’s comment, it seemed like some good information that other WordPressers may find useful. So, here are six ways to customize the sort order […] Continue reading »

Welcome to the Perishable Press “Blacklist Candidate” series! In this first post, we begin a new tradition of exposing, humiliating and banishing spammers, crackers and other worthless scumbags.. Every Wednesday, I take a little time to investigate my 404 error logs. In addition to spam, crack attacks, and other deliberate mischief, the 404 logs for Perishable Press contain errors due to missing resources, mistyped URLs, and the occasional bizarre or even suspicious behavior of the search-engine robots. Whenever possible, I […] Continue reading »

WordPress Tip: Reduce the Size of the WP-ShortStat Database Table

[ Screenshot: showing the relatively immense size of the WP-ShortStat table ]

In this article, I present a simple method for dramatically decreasing the size of your WordPress database by partially emptying old data from the WP-ShortStat table via the following SQL command: DELETE FROM `wp_ss_stats` ORDER BY `id` ASC LIMIT n That is the point of this entire article, which dips into just about everything one might need to know before employing such strategy. If you are familiar with SQL and understand the purpose and functionality of this command, feel free […] Continue reading »

Optimize WordPress: Pure Code Alternatives for 7 Unnecessary Plugins

[ Photo: Macro shot of a Yttrium claw ]

In this article, my goal is to help you optimize WordPress by replacing a few common plugins with their correspondingly effective code equivalents. As we all know, WordPress can be a very resource-hungry piece of software, especially when running a million extraneous plugins. Often, many common plugins are designed to perform relatively simple tasks, such as redirect a feed, display a random image, query the database, etc. For those of us comfortable with editing PHP and htaccess code, there is […] Continue reading »

Easily Adaptable WordPress Loop Templates

In this article, I present several heavily commented examples of WordPress loops. I have found that many readers appreciate these types of loop examples, as it helps them to understand how the loop works while enabling them to easily copy, paste, and adapt the code for their own purposes. In our first example, we examine a basic WordPress loop. When implemented, this loop will display “x” number of posts, where “x” represents the number specified via the WordPress Admin reading […] Continue reading »

WordPress Spam Battle: 3 Seconds that will Save You Hours of Time

In the hellish battle against spam, many WordPress users have adopted a highly effective trinity of anti-spam plugins: Akismet Bad Behavior Spam Karma This effective triage of free WordPress plugins has served many a WP-blogger well, eliminating virtually 99% of all automated comment-related spam. When spam first became a problem for me, I installed this triple-threat arsenal of anti-spam plugins and immediately enjoyed the results. Although Spam Karma seemed a little invasive and resource-intensive, too much protection seemed far better […] Continue reading »

htaccess Combo Pack: WordPress Permalinks and non-www Redirect

WordPress users employing permalinks via htaccess to optimize their dynamic URLs transform complicated-looking links such as: http://example.com/blog/index.php?page=33 ..into search-engine friendly links such as: http://example.com/blog/post-title/ Every rewritten URL relies on a common set of htaccess rules to transform the links. The htaccess rules for all WordPress permalinks look like this for root WP installations: # BEGIN WordPress <ifmodule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </ifmodule> # END WordPress ..and like this for […] Continue reading »
