Huge Collection of Code Snippets: HTAccess, PHP, WordPress, jQuery, HTML, CSS

[ WP Cron HTTP Auth ]

Please excuse this self-serving, miscellaneous post, but I’ve just got to purge all of these code snippets and scraps collected over the years. Whenever I update this site, I place any removed/unused code snippets into a giant note file for future reference, just in case. There’s all sorts of different types of code and snippets that just keep growing and growing and.. and finally it gets to a point where I just need to dump everything and start fresh.

The Art & Science of Folding CSS Code

One of the joys of working with CSS is that you can basically write the code any way you want. Sure there are some basic rules you have to follow (like using brackets), but for the most part you can format your CSS code as elaborately or as plainly as you see fit. You can use this vast flexibility to improve the organization and usability of your working stylehseets before compressing them for production use. Continue reading »

Upload Large Files or Die Trying

[ Screenshot: Editable and non-editable file permissions in Plesk ]

I recently spent some time wrestling with various e-commerce/shopping-cart/membership plugins. One of them was of course the popular WP e-Commerce plugin, which uses a directory named “downloadables” to store your precious goods. I had some large files that needed to go into this folder, but the server’s upload limit stopped me from using the plugin’s built-in file uploader to do so. Continue reading »

Humans.txt

[ Screenshot: Tweets about humanstxt.org ]

One thing I love about Twitter is the instant feedback. For the past few weeks I’ve been seeing lots of 404 requests like this: https://perishablepress.com/humans.txt https://perishablepress.com/humans.txt https://perishablepress.com/humans.txt At first I thought it was some skript kiddie getting creative, you know as a play on the robots.txt file, which is also located in the root of many websites. So it seemed interesting enough to tweet about: Continue reading »

Multiple Sitemaps

[ Screenshot: Settings for Google XML Sitemaps ]

Online Tools for DNS, CHMOD, Data URLs

I’ve always liked the idea of having an “Asides” category for links, notes, and other miscellaneous debris. So here is the first aside post, classified in the newly established asides tag (woo-hoo!). Here are three awesome tools to optimize your workflow. Continue reading »

HTTP Headers for ZIP File Downloads

You know when you you’re working on a project and get stuck on something, so you scour the Web for solutions only to find that everyone else seems to be experiencing the exact same thing. Then, after many hours trying everything possible, you finally stumble onto something that seems to work. This time, the project was setting up a secure downloads area for Digging into WordPress. And when I finally discovered a solution, I told myself that it was definitely […] Continue reading »

Target iPhone and iPad with CSS3 Media Queries

When designing a website, it’s always a good idea to test on as many different platforms, devices, and browsers as possible. These days, pimping your websites for the iPhone and iPad is an important step in the design process. Especially on the iPad, sites tend to look about 20% cooler than on desktop browsers, so you definitely want to take the time to fine-tune the details. And when dealing with iDevices, it’s often necessary to deliver some custom CSS to […] Continue reading »

Best Method for Email Obfuscation?

Awhile ago, Silvan Mühlemann conducted a 1.5 year experiment whereby different approaches to email obfuscation were tested for effectiveness. Nine different methods were implemented, with each test account receiving anywhere from 1800 to zero spam emails. Here is an excerpt from the article: When displaying an e-mail address on a website you obviously want to obfuscate it to avoid it getting harvested by spammers. But which obfuscation method is the best one? I drove a test to find out. After […] Continue reading »

How to Micro-Optimize Your CSS

[ Micro-Optimize Your CSS ]

There are many ways to optimize your web pages. In addition to reducing HTTP requests and delivering compressed files, we can also minify code content. The easiest way to minify your CSS is to run it through an online code minifier, which automatically eliminates extraneous characters to reduce file size. Minification shrinks file size significantly, by as much as 30% or more (depending on input code). This size-reduction is the net result of numerous micro-optimization techniques applied to your stylesheet. […] Continue reading »

[ pre box with long URL extending beyond width ]

Quick tutorial post today. To wrap long URLs, strings of text, and other content, just apply this carefully crafted chunk of CSS code to any block-level element (e.g., perfect for <pre></pre> tags): pre { white-space: pre; /* CSS 2.0 */ white-space: pre-wrap; /* CSS 2.1 */ white-space: pre-line; /* CSS 3.0 */ white-space: -pre-wrap; /* Opera 4-6 */ white-space: -o-pre-wrap; /* Opera 7 */ white-space: -moz-pre-wrap; /* Mozilla */ white-space: -hp-pre-wrap; /* HP Printers */ word-wrap: break-word; /* IE 5+ […] Continue reading »

htaccess Redirect to Maintenance Page

Redirecting visitors to a maintenance page or other temporary page is an essential tool to have in your tool belt. Using HTAccess, redirecting visitors to a temporary maintenance page is simple and effective. All you need to redirect your visitors is the following code placed in your site’s root HTAccess: # MAINTENANCE-PAGE REDIRECT <ifmodule mod_rewrite.c> RewriteEngine on RewriteCond %{REMOTE_ADDR} !^123\.456\.789\.000 RewriteCond %{REQUEST_URI} !/maintenance.html$ [NC] RewriteCond %{REQUEST_URI} !\.(jpe?g?|png|gif) [NC] RewriteRule .* /maintenance.html [R=302,L] </ifmodule> That is the official copy-&-paste goodness right […] Continue reading »

Top 5 CSS Shorthand Properties

An excellent way to simplify and streamline your Cascading Style Sheets (CSS) is to take advantage of the many different shorthand properties available to you. Working with a lot of CSS, you eventually memorize these different shortcuts, but every now and then, I find myself needing a quick, straightforward reference for some of the more elaborate property combinations. In this post, I’ll show you the shorthand rules for the following properties: Font Properties List Properties Background Properties Border and Outline […] Continue reading »

Visual Walkthrough of @font-face CSS Code

[ @font-face ]

In my previous post on Quick and Easy CSS @font-face Code, I provide a choice set of CSS rules for embedding custom fonts into your web pages. It’s a solid, cross-browser technique that works great, but as Marty Thornley pointed out, it would be useful to have a more thorough explanation of how the code actually works. So, rather than going back and adding a bunch of additional information to the original post, I’m following up with a visual walkthrough […] Continue reading »

Quick and Easy CSS @font-face Code

[ @font-face ]

I’ve been using custom fonts in my designs for quite a few sites now, and have refined what seems to be an ideal chunk of CSS code for implementing the @font-face rules. Some of the sites that include these rules include Perishable Press and Digging into WordPress, which look more stylish and refined with the custom fonts in effect. I’ve tested this code on quite a few browsers, including the following: Safari 3.1+ Opera 10+ Firefox 3.5+ Chrome 4.0+ Internet […] Continue reading »

Is it Secret? Is it Safe?

[ Enjoying the Evening ]

Whenever I find myself working with PHP or messing around with server settings, I nearly always create a phpinfo.php file and place it in the root directory of whatever domain I happen to be working on. These types of informational files employ PHP’s handy phpinfo() function to display a concise summary of all of your server’s variables, which may then be referenced for debugging purposes, bragging rights, and so on. While this sort of thing is normally okay, I frequently […] Continue reading »
