Choosing the Best Title Separators

While writing my previous article on creating the perfect WordPress title tags, I deliberately avoided discussing the use of separators in titles. I feel that the topic is worthy of its own article, enabling a more thorough exploration of the details. Title separators are the symbols, punctuation, and other characters used to distinguish between various parts of the page title. For example, a title may include the blog name, post title and blog description, with each element separated by a hyphen. Any Google search will reveal that some of the most commonly used title separators include the hyphen, the dash, […] Read more »

WordPress Error Fix: Unable to Parse URL

Note: This information is intended primarily for WordPress versions previous to 2.3, but may be applicable in other versions as well. For those of you running an older version of WordPress that is generating errors such as: Warning: parse_url(http://) [function.parse-url]: Unable to parse url in /home/path/to/public_html/wordpress/wp-includes/functions.php on line 1067 Warning: parse_url(http://) [function.parse-url]: Unable to parse url in /home/path/to/public_html/wordpress/wp-includes/functions.php on line 1067 Warning: parse_url(http://) [function.parse-url]: Unable to parse url in /home/path/to/public_html/wordpress/wp-includes/functions.php on line 1067 Warning: parse_url(http://) [function.parse-url]: Unable to parse url in /home/path/to/public_html/wordpress/wp-includes/functions.php on line 1067 Warning: parse_url(http://) [function.parse-url]: Unable to parse url in /home/path/to/public_html/wordpress/wp-includes/functions.php on line 1067 Warning: parse_url(http://) [function.parse-url]: […] Read more »

Open Call for Guest Posts at Perishable Press

After much deliberation, I have decided to take a short vacation away from the computer. I have been working like a dog recently, and feel that a change of pace would help recharge the ‘ol brain cells. I haven’t decided exactly when it will be, but I am thinking that some time off in August (my favorite month) would be swell. Maybe go to the coast, do some traveling, take a long nap, or whatever. Technically, I haven’t taken a break from blogging here at Perishable Press in almost three years! So it’s definitely time.. Generally, I like to post […] Read more »

85 Firefox Shortcuts for Mac and PC

As my browser of choice, Firefox provides all the functionality I need for web design, application development, everyday surfing, and much more. With a handful of choice extensions installed, Firefox is a lean, mean “get-it-done” machine. Plus, I am always looking for new ways to boost productivity and increase efficiency. Of course, an excellent way to do this involves learning and using as many mouse and keyboard shortcuts as possible. Over the past few years, I have collected oodles of shortcut snippets for Firefox. Thus, in an effort to purge my constantly growing stash of notes, I decided to round […] 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 »

How to Generate Perfect WordPress Title Tags without a Plugin

Keeping an eye on all things WordPress, I have noticed an ongoing fascination with configuring the ultimate WordPress <title></title> tags. Many bloggers use various plugins to generate differently configured <title></title> tags depending on particular page views. A good example of this is seen in the All in One SEO Pack, which, among many other things, enables users to specify custom titles for several different types of pages. While there is nothing wrong with this approach, some of us prefer to run WordPress with as few plugins as possible. If you want to create perfect WordPress title tags without a plugin, […] Read more »

Use Your Browser to Edit Any Live Web Page Using a Single Line of JavaScript

This was just too juicy to pass up. Blogstorm recently blogged about an easy JavaScript technique for making any website editable (404 link removed 2012/06/04). After checking it out for myself, I just had to share it here at Perishable Press. Here it is: javascript:document.body.contentEditable=’true'; document.designMode=’on'; void 0 Paste that single line of code into the address bar of any modern browser and have fun editing the page. Obviously, any changes will only apply to the page as seen in your browser, not the original document. Even so, it’s a fun trick to play around with, snap screenshots, be creative, […] Read more »

CSS Hackz Series: Targeting and Filtering Internet Explorer 7

Continuing the CSS Hackz Series, I present a small army of hacks for targeting and filtering Internet Explorer 7! Here, “targeting” IE 7 means to deliver CSS and/or (X)HTML to IE 7 only, while “filtering” means to deliver CSS and/or (X)HTML to every browser that is not IE 7. In other words, targeting is to include (apply), filtering is to exclude (hide). Let’s dive right in.. Conditional Comments Conditional comments are a proprietary Microsoft technique for targeting and filtering different versions of Internet Explorer. Other browsers do not understand them, and will treat them as regular (X)HTML comments. Of all the techniques presented […] Read more »

WordPress Tip: Link Author Comments to the Home Page

After almost three years of blogging here at Perishable Press, I had an epiphany about my author comment links. Way back when, after installing WordPress in a subdirectory called “/press/”, I decided to set the URL for my Administrative User Profile’s website as “http://perishablepress.com/press/”. After all, it seemed to make sense at the time, plus it really didn’t seem to matter; nobody was going to see my personal profile information anyway, right? Wrong. Three years later, I finally realize that it does matter. The URL that you enter as your profile’s website address is the URL that will be used […] Read more »

Yahoo Incongruities.

When frustration builds, and finally reaches its the boiling point, it’s nice to be able to express yourself to someone. Although I really don’t enjoy ranting about things, but when it comes to certain aspects of Yahoo!, I just can’t he’p myse’f. So, thanks to recent attempt at using My Yahoo!, it’s time to get some of this off my chest, clear the decks, and give Yahoo! (yet another) chance to clean up its act. Here are a few complaints I have against various aspects of the Yahoo! enterprise.. First and foremost, Yahoo! sends virtually zero traffic. I know this […] 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 »

WordPress Tip: Disable Comments in Old Posts via PHP

Just a quick WordPress snippet for future reference. I recently explained how to disable comments, pingbacks, and trackbacks via SQL. Here’s a good way to do it via PHP: <?php function close_comments( $posts ) { if ( !is_single() ) { return $posts; } if ( time() – strtotime( $posts[0]->post_date_gmt ) > ( 30 * 24 * 60 * 60 ) ) { $posts[0]->comment_status = ‘closed'; $posts[0]->ping_status = ‘closed'; } return $posts; } add_filter( ‘the_posts’, ‘close_comments’ ); ?> You can run this script as a plugin, through your theme’s functions.php, or through a custom user-functions.php file. Simply set the desired number […] Read more »

Working with Multiple Themes Outside of the WordPress Installation Directory

As you may observe, the WordPress installation that powers Perishable Press is located in a subdirectory named press. This configuration was intentional, as I wanted to have the option to easily install and maintain multiple versions of WordPress in variously named subdirectories. As much as I enjoy this flexibility, many would argue the SEO-related benefits of installing WordPress in your site’s root directory, or at least making it appear that way by using WordPress’ easily customizable “Blog Address” options setting. For example, say you have WordPress installed in a subdirectory called “gibbonz”, but you want your blog’s home page to […] Read more »

Obsessive CSS Code Formatting: Organization, Comments, and Signatures

One of my favorite aspects of producing clean, well-formatted CSS code is “meta-organizing” the document using comments. In CSS, comments are included in the stylesheet like so: /* i am the walrus */ When used constructively, CSS comments serve to break down documents into distinct regions, provide key information about specific declarations, and bring order to even the most complex stylesheets. In my experience, a well-commented stylesheet improves efficiency and optimizes comprehension. Working with CSS, you can add comments any way you want. There are many different ways to use CSS comments, and endless ways to get there. Let’s check […] Read more »

A Sincere Attempt to Switch from Firefox to Opera

I recently twittered my intention to switch from the Firefox browser to the sleek, new Opera 9.5. I have always used Opera as a secondary browser, especially handy for speedy jumps into cyberspace, browser testing, and taking up space on my hard drive. I have always wanted to switch completely to Opera, but for many reasons, Firefox just keeps pulling me back into its comfortable grasp.. After a quick Opera-9.5 download, I decided to install Opera in its own directory instead of upgrading my current 9-point-whatever version. Unlike some browsers, multiple installations of Opera require nothing more than separate directories […] Read more »
