Roll Your Own “What’s My IP Address?” Page

My current ISP likes to keeps things spicy by changing my IP address every few months or so. There are a million ways to get this changing IP information, but as an obsessive web developer, I like to roll my own whenever possible. That means using my own resources instead of spending time and energy elsewhere. So the goal for this project is to create a web page that does one thing very well: display the visitor’s current IP information. In this tutorial, we use PHP, HTML, CSS, and JavaScript to roll our own sleek & stylish “What’s my IP” […] Read more »

Ajax-Powered Error Logs for WordPress

Update: Check out the new and improved Ajax Error Logs for WordPress v2.0! In my previous post, I share my technique for Ajax-Powered Error Logs. That tutorial shows you how to set up dynamic error monitoring on any typical website, but the script requires some tweaking to get it working with WordPress. In this quick post, I explain how to set up Ajax Error Logs specifically for WordPress sites. Read more »

Ajax-Powered Error Logs

Update: Check out the new and improved Ajax Error Log Version 2.0! As an obsessive website administrator, I like to keep a keen eye on my error logs. Once a week, I download my PHP, 404, and other error logs, and analyze them as closely as time allows. Monitoring site errors and other traffic patterns leads to many of the security-related articles I post here at Perishable Press, including resources such as the 5G Blacklist, Ultimate HTAccess Blacklist, and the Blacklist Candidate Series. Easily, one of the best ways to protect your site is to understand the different types of […] Read more »

Ajax RSS Feeds with More Sidebar

After implementing Chris Coyier’s More Sidebar technique here at Perishable Press, I needed a good source of “filler” content for the “more” blocks. After experimenting with multiple loops and template tags, the idea of sliding in RSS feeds seemed like a better solution. Replacing some empty space with great content is a win-win for everyone. For example, I display a few of my recent tweets in the sidebar to help fill a lil’ space. It’s a great way to share stuff, and it’s pretty easy to do. Read more »

Ajax Slide & Fade Content with jQuery

I recently redesigned my business site, Monzilla Media. The new design features a clean and simple single-page, fixed-sidebar layout. Visitors use the various links in the fixed sidebar to quickly and automatically scroll through to any section. In the Portfolio section, each item contains a “Details” link that loads more content into the fixed sidebar. As the site is mostly static, I wanted this bit of functionality to really shine, and after much testing and tweaking, ended up with a cross-browser slide & fade technique for loading content via Ajax and jQuery. Note this technique has been updated to work […] Read more »

Display Latest Tweet with Show/Hide Cookies

Update (2013/08/03): This simple technique no longer works thanks to the 2013 Twitter API, which makes it much more complicated to grab your latest tweet. For WordPress, check out the Latest Tweets Widget. My previous theme displays my latest tweet at the top of every page. It turned out to be an excellent technique for getting more followers – visitors see the tweet, click the link, and possibly follow me on Twitter. There is even a cookie-powered “Hide” link for uninterested visitors to hide the tweet for awhile. I received quite a few requests for a tutorial on the technique, […] Read more »

Protect Your Site with a Blackhole for Bad Bots

One of my favorite security measures here at Perishable Press is the site’s virtual Blackhole trap for bad bots. The concept is simple: include a hidden link to a robots.txt-forbidden directory somewhere on your pages. Bots that ignore or disobey your robots rules will crawl the link and fall into the trap, which then performs a WHOIS Lookup and records the event in the blackhole data file. Once added to the blacklist data file, bad bots immediately are denied access to your site. I call it the “one-strike” rule: bots have one chance to follow the robots.txt protocol, check the […] Read more »

Beware of Margins or Padding when Using the min-width Hack for IE

While we all watch as Internet Explorer 6 dies a slow, painful death, many unfortunate designers and developers continue to find themselves dealing with IE6’s lack of support for simple things like minimum and maximum widths. Fortunately, there are solutions to this problem, primarily in the form of CSS expressions such as this: /* set the minimum width for IE 6 */ #target_element { width: expression((document.body.clientWidth < 335)? “333px” : “auto”); /* min-width for IE6 */ min-width: 333px; /* min-width for all standards-compliant browsers */ } Although ugly, invalid, and resource-intensive, this technique works well at setting min-width properties for […] Read more »

Unobtrusive JavaScript: Auto-Clear and Restore Multiple Form Inputs on Focus

In an effort to organize my pile of offline notes, I will be posting a number of quick, “to-the-point” tutorials on a number of useful topics. In this post, I share an excellent method for auto-clearing and restoring multiple form field inputs using a bit of unobtrusive JavaScript. This method was discovered at xy.wz.cz. There are two steps to this technique, which should take no longer than five minutes to implement. Read more »

Provide a Link for Visitors to Verify Your Feedburner Subscriber Count

Recently, I received a bizarre email accusing me of calling someone out on their fake Feedburner subscriber count. Apparently, some desperate blogger had been claiming to have something like 30,000 Feedburner subscribers when in reality they only had around 700. From what I could tell, the fraudulent site was displaying a counterfeit Feedburner subscriber-count badge using some fancy CSS image-replacement or something. Whatever. I really could care less, but the information contained in the email got me thinking: Providing an easy way for visitors to verify your subscriber count is a good idea.. Enabling visitors to quickly and easily verify […] Read more »

How to Display Your Twitter Posts on Your WordPress Blog

Alright, time for another “How’d-you-do-that-thing-on-your-site?” post. This question comes from the one and only Mr. Graham of ImJustCreative.com. In a recent email, Graham literally begged me to share my “secret recipe” for displaying my latest Twitter Tweets (wow, did I actually just say that?) right here on Perishable Press: …Would be really really decent of you if you could let me know how to do it? Pretty please? How do you call the last twitter feed, what commands do you need etc? In case you have no idea what we’re talking about here, scroll down to the bottom of any […] Read more »

CSS/(X)HTML Tutorial: Hovering Accessibility Jump Menu

Recently, a reader named Don asked about this theme’s accessibility (accesskey) jump menu located at the top of each page. Several people have commented that they like the way the jump menu “lights up” upon gaining focus. Whenever a user hovers their cursor over the region at the top of the page, all links in the jump menu change to a more visible color. Then, as the cursor moves over the various menu items, each jump link is further highlighted with an even brighter color and an underline. This progressive focusing is best seen in browsers that support the CSS […] Read more »
