The 3.1 update to Yoast’s WordPress SEO plugin brought with it a new feature—the ability to set a “Primary” category for a post. You’ll now see a “Make Primary” link when selecting categories (or a bold “Primary” label if one has been set). It's possible to use this primary category in a custom theme...
Yoast's WordPress SEO plugin will automatically "ping" search engines that your existing XML sitemap is updated. But what if you want to disable this? The plugin settings do not have an option for this at the moment, but luckily there is a filter that can be hooked into with a line of code.
Say you want to create a button whose background in the top left is one color, and a different color in the bottom right. The color is basically split with a diagonal line from the bottom left corner to the top right corner. It seems simple, yet a lot of the CSS techniques I came […]
Oh my Glob! BMO in the Web Thingey. All the visuals are done entirely with CSS. The buttons also do some mysterious things when you press them. The making of 3D BMO grew out of following a tutorial creating an old Macintosh Plus in 3D with CSS. I wanted to better understand the CSS properties that were being used for 3D, and create something myself. In doing so, I ended up figuring out some math to create some beveled/rounded edges.
High ratings in the Google Play Store or iOS App Store are critical to an app’s success. And they’re beneficial to find out what the problems are when an app needs improvement. So, it’s very common to have a simple link/button that allows the end user to submit their review from inside the app. The less hoops to […]
Every site we build on the Rackspace Cloud ends up needing a lot of similar rules in the htaccess file. On my local PC I've collected them in a text file, that I copy paste sections from almost every day.
Most of the below examples will work on your average Linux-based server with Apache and mod_rewrite enabled. A few are RS Cloud Sites specific (as noted). In case you've never messed with this stuff before, note that this isn't a single file to copy in its entirety. Each section has a different purpose.
Using Yii's implementation of ActiveRecord makes querying a database much easier for simple queries. For more complex situations, you will still find yourself having to write some straight SQL on occasion. In this case, using a custom query was not necessary. I was trying to add another search parameter, using the AR compare() method, to search a relation with a HAS_MANY relationship, and it was displaying an "unknown column" error. Without a proper example, it wasn't clear at first how to get this work...
Starting last month, Rackspace Cloud Sites has not been delivering mail sent through PHP's mail() function in a timely matter, and sometimes not at all. The company I work at has been using RS Cloud Sites for a few years now, and while mail delivery has always been slower than average, emails tended to arrive within 20 minutes. Now we have emails showing up 3 days late, and there were some tests that I never received.
Why is there no uproar about this? And why has Rackspace failed to notify its customers of this ongoing issue?
Most websites rely critically on scripts that send email for their contact forms and web applications. For any brochure-type website, the main goal is to get the visitor to contact them. Call to actions point to a contact form. The contact form submits to a script that either sends mail via PHP's mail() (sendmail) or via SMTP.
I was adding a nice hover overlay to some images, which faded in and out nicely with jQuery, in FireFox. Unfortunately, the effect in IE7 and IE8 was not looking too good. The text was either not fading correctly, or text was popping and looking shoddy. This had to do with some transparent elements and handling of transparent PNGs. Rather than fighting with it or degrading it for everyone, I realized it'd be simple to do a little progressive dehancement by doing a simpler show/hide for IE versions less than 9.
I recently was tasked with converting a Tumblr blog into WordPress. On Tumblr, or at least on the theme I was dealing with, they have a pretty fancy archive section that lists all the posts as images underneath the months. If there aren't images, then it shows a little text. To do something similar...
Using the @media rule in your CSS allows you to target different media types, and screen sizes, from a single stylesheet. Using media queries with max-widths is integral to the current push towards responsive design. This can also be used to create your print styles using @media print. You'll notice this used on modern base-templates such as the HTML5 BoilerPlate:
Adding a “Subscribe to Newsletter” checkbox or radio button to an existing contact form is incredibly painless using the MailChimp API. Include one library file, and you’ll have access to all functions the API has to offer. In this example, I added a Yes/No radio selection. You could easily change this to be a checkbox. When "Yes" is selected, and the form is submitted, the contact form does its thing, and then the user is added to a MailChimp List.
If you're locked out of WordPress and can't reset your password, the official docs list several options that allow you to access your administrator account again. But what if you want to create an entirely new admin user? For blogs that I have FTP access to, but no working WordPress password, I threw together the following script to create admin users.
Most sites contain areas of text and HTML that are repeated throughout the site. Links in the footer, copyright information, a button or phone number in the header, or some other static content. If you're a developer working on your own site, then you may just keep this in an include file and edit the code manually. If you're using Wordpress as a CMS for a client, then it's a good idea to make these areas of text/images editable, so that they can have full control of their site.
