When I started my little experiment with showing icons on custom taxonomies, I began with a text field. This was because it was the easiest to edit and change right away. Next I changed it to a selection dropdown, based on the content of the folder where the I’d stored my images.
And for the most part, that’s pretty cool. Except for the part where drop-down select boxes can’t show images. This meant I had to show the image name. Generally that’s okay. I know the name of the image I wanted to use. The problem is that I know that because I know the images I uploaded. For someone else, that’s 800 images or so they have to guess at, based on names.
After playing around with selections and forms for a while, I determined there really isn’t a great way to show a list of images natively. No matter what I was going to have to mess with this the un-fun way because the easy way, CSS, failed. You can use background-image in Firefox but not Chrome or anything else that people use.
Good news! As of jQuery UI 1.11, the selectmenu widget exists. Bad news! It’s not actually simple to implement. In fact, I absolutely failed at implementation. Let’s talk about why I failed, because it’s not just a matter of how convoluted the code is.
A large part of my failure in this is due to the scale. If you only have one or two images, it’s less stupid. But when you get around to sets of 800 images, you start to understand why WordPress has a media uploader the way it does.
The biggest factor, though, is that searching ‘visually’ is a difficult system to maintain. Symbology, the art of getting a ‘thing’ to represent another ‘thing’ is incredibly hard to pin down. Look at your WordPress dashboard. Why does a pushpin represent posts when they’re not all that different than the ‘two sheet’ icon of pages in functionality? Why is users a single person icon and not multiple people?
Ask yourself this: if you’re adding in a new menu item, what do you make your icon? Do you make it your brand logo (a G in a circle for StudioPress’ Genesis theme)? Maybe you make it a cloud with a down arrow to indicate downloads (as does Easy Digital Downloads). We wanted to add in a new Custom Post Type for ‘Characters’ and ‘Shows’ for my database site and Tracy, who is amazing at this sort of thing, cheekily picked a video camera for ‘shows’ and a name tag for ‘characters.’
I had a related but slightly different issue when I wanted to use Mark Jaquith’s meta I Make Plugins plugin. I wanted to see my plugins on the sidebar with a more unique icon. I couldn’t use the most logical one, a plug, since we’re already using that for Plugins. I went with a little ‘awards’ icon.
In both cases, we studied the list of Dashicons and picked the ones that made the most sense, but it required a visual study of what we really needed and an understanding of how they all worked. Scrolling down a massive list of all of those is annoying, but necessary. You need to look at your options, think about them, and feel what they mean contextually.
I haven’t yet figured out a perfect solution, but I’ll let you know when I do.
