Pimp Your 404: Presentation and Functionality

[ Screenshot: Default Apache 404 Error Page ]

I have been wanting to write about 404 error pages for quite awhile now. They have always been very important to me, with customized error pages playing a integral part of every well-rounded web-design strategy. Rather than try to re-invent the wheel with this, I think I will just go through and discuss some thoughts about 404 error pages, share some useful code snippets, and highlight some suggested resources along the way. In a sense, this post is nothing more […] Continue reading »

Block Multiple IP Addresses with PHP

[ Screenshot: The Legion of Doom ]

Let’s face it. There’s just as much scum on the Internet as there is out there in the “real world.” Maybe even more, who knows. From scammers and spammers to scrapers and crackers, the Web is just crawling with all sorts of pathetic scumbags. As predictably random as much of the malicious activity happens to be, it is virtually guaranteed that you will be hounded by at least a few persistent IP addresses that, for whatever reason, have latched on […] Continue reading »

9 Ways to Set Dynamic Body IDs via PHP and WordPress

When designing sites, it is often useful to identify different pages by adding an ID attribute to the <body></body> element. Commonly, the name of the page is used as the attribute value, for example: <body id="about"></body> In this case, “about” would be the body ID for the “About” page, which would be named something like “about.php”. Likewise, other pages would have unique IDs as well, for example: <body id="archive"> </body><body id="contact"> </body><body id="subscribe"> </body><body id="portfolio"></body> ..again, with each ID associated […] Continue reading »

WordPress Tip: Valid, SEO-Friendly Email Permalink Buttons

Amazing but true..

In addition to your choice collection of “Share This” links, you may also want to provide visitors with a link that enables them to quickly and easily send the URL permalink of any post to their friends via email.

Temporary PHP Redirect: Allow Multiple IP Access and Redirect Everyone Else

[ Image: Abstract Mathematical Diagram ]

In my previous article on temporarily redirecting visitors during site updates, I present numerous PHP and HTAccess methods for handling traffic during site maintenance, updates, and other temporary periods of downtime. Each of the PHP methods presented in the article allow for access from a single IP while redirecting everyone else. In this article, we modify our previous techniques to allow access for multiple IP addresses while temporarily redirecting everyone else to the page of our choice. Plus, while we’re […] Continue reading »

PHP Short Open Tag: Convenient Shortcut or Short Changing Security?

[ Echo Shortcut Code ]

Most of us learned how to use “echo()” in one of our very first PHP tutorials. That was certainly the case for me. As a consequence, I never really had a need to visit PHP’s documentation page for echo(). On a recent visit to Perishable Press, I saw a Tumblr post from Jeff about the use of PHP’s shortcut syntax for echo() but somewhere deep in my memory, there lurked a warning about its use. I decided to investigate. Continue reading »

WP Custom Fields, Part II: Tips and Tricks

[ Magnetic Fields ]

As we have seen in our previous post, WordPress Custom Fields Part I, custom fields provide an excellent way to add flexible content to your posts and pages. By assigning various types of content to different custom fields, you gain complete control over when, where, and how to display the associated information. For example, sub-headings may be displayed in the sidebar, footnotes may be consolidated into a single region, post images may be displayed before the post title, and so […] Continue reading »

WordPress Custom Fields, Part I: The Basics

[ Magnetic Fields ]

I recently developed a theme that makes heavy use of WordPress’ custom fields. The custom-field functionality of WordPress makes it possible to rig up just about any customized layout quickly and easily. Custom fields enable designers to organize post content into different sections, making it possible to create non-linear page layouts, with different types of content easily removed from the normal post loop and relocated to different parts of the document. This organizational and design flexibility has the added benefit […] Continue reading »

Some time after the article had been posted, Mat8iou chimed in with a couple of ways to improve thie script by cleaning up […] Continue reading »

Redirect any Subordinate URL to its Parent Directory via PHP

Simple one for you today. After posting on how to use HTAccess to redirect subordinate URLs to the root (or parent) directory, I thought I would share an alternate way of accomplishing the same trick using PHP. Fortunately, using this PHP redirect technique doesn’t require access to or fiddling with your site’s HTAccess (or Apache configuration) file and it is very easy to implement. The scene, as discussed in greater detail in my previous article on this topic, involves a […] Continue reading »

With the explosion of social media, networking, and bookmarking services, there are a zillion ways to add “Share This Post” functionality to your WordPress-powered sites. In addition to the myriad services and plugins, we can also add these links directly, using nothing more than a little markup and a few choice PHP snippets.

This article shares […] Continue reading »

Fruit Loop: Separate any Number of Odd and Even Posts from any Category in WordPress

[ Fruit Loop ]

Recently, I discussed how to implement a horizontally sequenced display order for WordPress posts in two columns. In that tutorial, I explain how to separate odd and even posts using a dual-loop configuration and PHP’s modulus operator. Such technique serves well a variety of configurational scenarios, but is limited to the display of the default (admin-specified) number of posts from all categories. In this tutorial, we adapt this odd-and-even loop configuration to accommodate a much greater degree of customization. Specifically, […] Continue reading »

Welcome to the Perishable Press “Blacklist Candidate” series. In this post, we continue our new tradition of exposing, humiliating and banishing spammers, crackers and other worthless scumbags..
