WP Features: Theme or Plugin

Posted on by Evan Mullins

Reading my wpdaily.co updates today and saw this post talking about WordPress theme features. Eric explains the debate:

Generally-speaking, the conversations have always circled around features: There are those that believe every feature you could ever imagine should be included like text color, font selector, and more. On the flip-side, there are those that feel WordPress themes should be finite and extra features should only be added when it’s niche specific.

He says the the main problem is theme bloat, but I think it’s more about the lock-in effect some themes have on users. If they customize it or add content via functionality provided by the theme, then if they switch they no longer have access to it (although the content does persist in the database, there’s just no longer an interface to accessing it).

many-theme-options

If users are stuck in your theme because it’s the only way they know how to show their content then it becomes problematic. I’m curious as to how often users are going around changing themes though. Are they changing themes for more/different functionality or for a new look? I find myself changing a theme every couple years or so to update the site, but that’s usually in a whole redesign phase and not just switching around for fun. Should theme switching be more frequent?

I also see it from the user perspective. They just want to purchase/install a theme and be running, they may not have the patience or expertise to 1) find the right plugin 2) install it and set it up, so they’d prefer it be in the theme as a package deal.

Partly, I don’t see it a problem including CPT info in a theme, because that’s where you have to style it anyways, right? Users want their post types, but they also want the templates and styles and functionality/integration with the site that go along with them, and I think a theme is the easiest place to keep all that for the developers as well as the users. Plugin shouldn’t have all the styles for the CPT content and can’t have the template files because then if they switch the theme the styles conflict with the new theme. They may end up having to learn CSS to switch the theme anyways. The users are going to want their data displayed properly as well as it be accessible on their site. So if a new theme would not properly display or integrate the CPT data, then why have it included at all.

Eric does offer some alternative solutions:

Offer a Support License purchase option that allows users to follow tutorials for their own customization.
Offer free downloadable plugins that work exclusively with your premium theme that adds easy functionality.
Offer tiered theme versions–beginner, advanced and developer.

I like the idea of including a plugin to add functionality, but I’d suggest that rather than making it exclusive, make it work with any theme, just make sure your theme supports it (along with other popular plugins).

There is talk about making extra theme functionality ‘opt-out’ for those experienced enough to do so. Set a variable in the functions.php file or even comment out a block of code to remove some customization options to it can be done via a plugin. This, although more work, seems like a good option. Providing the features by plugin makes sense, but asking beginner users to do that extra work seems like unnecessary friction.

Also, it’d be nice if WP had a built in UI for custom post types and custom taxonomies and even custom fields and meta boxes in core. Lay users could then easily create content types and manage data. WordPress would be a tool to create your own custom CMS. Theme developers could create post types as well and then WP would be smart enough to detect data in a CPT table and include the needed UI. Then the users could create/manage content types so if they installed a theme that created a custom post type, since it was now in the database, it would stay even if the theme changed. There are many rabbit holes here, but I feel like I’m onto something and would be excited to see WordPress go this direction.

Packery Preview, from Metafizzy & descended from Masonry

Posted on by Evan Mullins

David Desandro / metafizzy, maker of masonry and isotope of which I’m a big fan and user of has been busy with a new project called Packery.

Packery, looks to be a child of Masonry. As you would expect it seems to be pushing things much further and addressing a few pain points of masonry. He’s boasting in this blog post that it will optionally support grid layouts, and give you the option to go grid-less for a more haphazard looking layout. It will allow filling holes and adding elements on the fly, but most impressively… We’ll have drag and drop support (including touch support and multitouch support)! You drag an item around the grid (or non grid) and watch live as elements reposition to embrace the newly placed item! Very cool and I can’t wait to play with it.

Read up on the Packery preview from Desandro on his Metafizzy Blog.

Android App Development Keystore for Beginners

Posted on by Evan Mullins

Getting into some mobile app development for Android and I was unprepared for the keystore file that is required to be included in the apk file. Using PhoneGap Build to compile my app the interface requires a keystore file uploaded.
Screen Shot 2013-02-05 at 1.55.07 PM
After some digging on google it seems that the most common way to create a keystore file is by using some Java IDE like Eclipse, but the whole reason I was using build phonegap was because I didn’t want to fool with one of those. I finally pieced together what I needed with a few posts and wanted to put it all together to help at least myself in the future.
phonegap keystore upload alias
Luckily with a mac apparently you can do this with terminal! Following a couple tutorials, I managed to create a proper file, and going through a few steps to set the expiration or validity and the alias.

To create a keystore on mac OSX, first, open terminal. We’ll type keytool and then there are some commands to type and our keystore file will be created. -genkey (generates the key), -v turns on verbose mode so full details will be output, -keystore tells it what to name the actual file (it actually saves to the root directory, I’m sure there’s a way to specify location somewhere) and you type the filename (including the .keystore file extension). Once you enter this in you are prompted to fill out your name and company name and info like city, state and country. Then it verifies everything and you must type ‘yes’. Then it will prompt twice for a password, remember this it is how you will update/rebuild your app.

keytool -genkey -v -keystore file_name.keystore

This got me going but I had to do some back and forth to know some other requirements specifically for android marketplace and working with PhoneGap. PhoneGap Build was asking for the alias when I uploaded the keystore file to build my project, but I hadn’t set one. I had no idea what it would be and after trying my name and company and even filename I had to do some more digging. We can in fact set the alias name when I create the key with the -alias command. It doesn’t matter what this is, you just have to remember it. I think of it like the username to my previously entered password. The default is set to mykey, so you don’t really need to set it. This got me through the Build process with PhoneGap, and then I set up my app on the android marketplace (after paying the $25 license fee). Once I uploaded my first apk file I was getting errors regarding the keystore again. The marketplace was telling me that the validity was not large enough. The validity (or expiration) of the key by default is set to 90 days, but the marketplace requires at least 10000 days… quite a difference, no? So to set validity we add the -validity command followed by the value of 10000. Once i did this round I re-uploaded the keystore to PhoneGap, rebuilt the app and resubmitted to the Android Marketplace and it was accepted! Wow.

keytool -genkey -alias alias_name -validity 10000 -v -keystore file_name.keystore

terminal creating a keystore file for android apk

I hope that helped someone. I’m surprised that the PhoneGap doesn’t aleviate some of the pain in this process. Since the whole point of using Build PhoneGap is so that I don’t have to set up an IDE or get complicated. A simple online keystore gen process would go a long way, and better yet if they automated it somehow!

Did I miss any steps? Are there better ways to do this? (I sure hope so) Share a comment.

Also, check out the app I made from web technologies html, css and javascript with the help of PhoneGap. It’s a quiz that tests and teaches users facial recognition of leaders at church. It’s called LDSQuiz and shows images of modern day prophets and apostles and asks you to identify them by name.

Set Default Terms for your Custom Taxonomies

Posted on by Evan Mullins

Custom Taxonomy Default Term(s) for when it’s left blank

After looking through the WP codex and various plugins, I couldn’t find anywhere to set a custom taxonomy default term. WordPress has allowed us to create custom taxonomies for a while. Before we only had categories and tags hard coded in core. One feature from those days that didn’t seem to make it to the custom taxonomies of today is the possibility to select a default taxonomy term if none are selected. Did you know about this feature? Odds are you did, even if you didn’t realize it. Have you ever seen that ‘uncategorized’ category? That was the default category added for any content that didn’t have a specific category and was left, well, uncategorized.
uncategorized-default-post-category
An annoying feature if you weren’t expecting it, but nice to have if you took the moment to actually set up your default properly. I was working on a project recently with custom post types and custom taxonomies and suddenly needed this feature, but it didn’t seem to exist, so a few google’s later I found this nice snippet from Micheal Fields. Adopting the hook and adding some to allow for custom post types I wanted to share it here for my own safe keeping as well as the benefit of the community.

To Code Custom Taxonomy Default Terms

[cc lang=”php”]
/**

*/
function mfields_set_default_object_terms( $post_id, $post ) {
if ( ‘publish’ === $post->post_status && $post->post_type === ‘your_custom_post_type’ ) {
$defaults = array(
‘your_taxonomy_id’ => array( ‘your_term_slug’ )
//’your_taxonomy_id’ => array( ‘your_term_slug’, ‘your_term_slug’ )
);
$taxonomies = get_object_taxonomies( $post->post_type );
foreach ( (array) $taxonomies as $taxonomy ) {
$terms = wp_get_post_terms( $post_id, $taxonomy );
if ( empty( $terms ) && array_key_exists( $taxonomy, $defaults ) ) {
wp_set_object_terms( $post_id, $defaults[$taxonomy], $taxonomy );
}
}
}
}
add_action( ‘save_post’, ‘mfields_set_default_object_terms’, 100, 2 );
[/cc]
This code hooks to ‘save_post’ and fires when the post is saved. It will check the post status and only execute if the post status is set to publish. My addition will also check the post type against your custom post type. Then it sets the default for any taxonomy that you want to set a default for. Either a single term or multiple terms can be set as the default taxonomy term. If you want multiple default terms then you just use a comma separated list. This hook will then load the existing taxonomies and if they are not yet set on the post it will set them to your designated default(s). It’s nice and flexible as you can have multiple taxonomy defaults set quickly in the defaults array. Thanks Michael!

Working out a Math Problem | BIT-101

Posted on by Evan Mullins

I love how math creeps into design, programming and other problem solving.

I had some fun playing with Keith’s code (as usual). I’m always impressed with how he’ll see a problem and eventually at least figure out how to solve it using math/trig/physics. It’s a breath of fresh air and it almost makes me wish I was a math teacher and I could whip the example out whenever a student says ‘how is math useful’. I use it and even enjoy using math in my work to solve problems and it what bits I paid attention to in school still really help me.

Anyways, Keith was trying to figure out how to have a ring of a certain number of exactly touching circles around one central circle of a predetermined size. Sounds like a perfect bonus question from trig, right?
Here’s his post: Working out a Math Problem | BIT-101. And then his follow-up post where he gets to what I was expecting in some nice renderings showing how he’s using this simple pattern to make some really interesting designs.

I commented that I liked his problem solving procedure and was interested to see it animated! I love how math creeps into design like this. So I toyed a bit with animating the form. Check out my jsbin at http://jsbin.com/icahul/132/edit.

Adding Viewport Meta Tag via WordPress Theme Functions

Posted on by Evan Mullins

Add the viewport meta tag with a WordPress hook via your theme’s functions file to allow responsive web design and mobile-friendly themes

meta-viewport-thumbWith all the responsive web design activity over the past few years, I hope that any theme or site we work on we’re able to make responsive to some extent. An important part of making a web site responsive is adding a viewport meta tag to your html. Without explicitly stating our viewport, the mobile browsers will scale down the website to fit into their ‘viewport’. This is a good thing, since if it was a full website and the browser didn’t scale it down, you’d only see the top left corner, or some small section of the site. This viewport was introduced by apple for iOS and has spread to most mobile devices since. There are viewport properties or parameters we can set with this meta tag such as width and scale and can even use some device aware variables (like ‘device-width’) to set these values.

A WordPress Meta Viewport Hook

I usually end up using the following hook to add a viewport meta tag to my head in wordpress. I set the viewport width to match the width of the device. Then I set the initial scale to 1. Some go and set the maximum-scale to 1 as well. This would prevent users from zooming in on your site. I advocate that we should allow users to zoom if they wish since it is a gesture they may be used to and may still need (no matter how nice your RWD is, they may need/want to see it bigger). RWD is about giving the user a better layout for whatever device they are on, not restricting how they view it.

Randomness and Unicorns for Programming

Posted on by Evan Mullins

book

Programming seems to have a gulf dividing the playful and the useful. The random and scripted. The fun and the business. KrazyDad writes the book review and calls for a concerted effort to close this gap. The pleasurable and “recreational programming” mindset seems to be giving way to OOP and other acronyms that do little to inspire new programmers to experiment. While I agree I also think that the web of today makes a lot of old boring aspects – now playful. There are things like the 1K competitions, and all the magic that is now coming our with these new CSS3 properties. Although it’s not enough, I think there is at least a spark of it, and agreed it could be better in that it could be easier for newbies to jump in and experiment without understanding so much first. Thanks for the book recommendation Jim, I’ll add it to my list and hopefully get an into to BASIC.

For a long time, the amount of joy I derived from writing software was proportional to the amount that the features depended on randomness. There is a relationship between the RND() function and the perception of utility. To me, programs that are useful, and that do not require randomness, are useful, but boring — they fill out your tax return and monitor patients in hospitals. The RND() function is like a firehose from God, and the programs that use it are useless, but fun — they are games, and simulations, and art.

Web vs Mobile – For The User

Posted on by Evan Mullins

I agree with this idea from Ryan that the web has big advantages. I am constantly hearing stats and projections that Mobile is taking over. And sure, I agree that I use my phone to browse more sites, but when it comes down to it I’m just casually browsing – not working. I love the post he’s links in the first line: Vibhu Norby has a detailed post on why his startup is pivoting from mobile first to web first.

Vibhu details that he’s done the mobile startup thing and has learned from the complications. He explains that most of these have been solved in the desktop browser already and a lot of it relates to usability.

Another big point is that mobile apps must be installed (actually they must be found, installed, opened and setup), whereas a web app can be as simple as a link- click, and then the user is already using it. Adoption is much easier on the web.

And even another point is updates and testing and whatnot. YOu can do various tests and even update the whole app relatively fast on the web. There is the one version to support – the live one. While with apps, you can’t do much in the arena of testing and updating is sluggish plus it relies on the user to update (some don’t know how to update and even less care).

I think a web app that is mobile friendly wins. You can give mobile users access, but they aren’t stuck on mobile. They can use it anywhere. While so many are talking about responsive design and produce sites that are device agnostic mobile apps are very device centric.

I’m a fan/advocate of future friendly at least, and strive for future proof (although I understand that’s near impossible). I also hold that there is ONE web and mobile myths.

Here's a great data visualization timeline showing an individual's programming history: what languages and when and how much. I think it's a very pleasing visual too. He's posted the code to github to play with. Could be a very interesting addition to a bio or resume.
