Dealing with Depression

Somedays are better than others. Somedays just suck. Somedays are pretty good. Lately, I’ve been on the lower end of the spectrum. I’m not sure what it is, but the past few weeks have been harder than usual. The mental breakdown between productivity and laying in bed all weekend is a finer line than I would like. This might just be a little rant, but as I was reading through Reddit, I got the urge to write down some thoughts so I’m going to vent. Hello stranger! I hope your stay here is fruitful.

Maybe this all started with the celebrity suicides? I have to admit, while I did know of both Chris Cornell and Chester Bennington, I never really knew much about them. Sure, I listened to Soundgarden and Lincoln Park, but I wouldn’t describe myself as anything more than an extremely casual “fan”. Seeing the interaction though, watching how one person’s decision had such a profound effect on someone else; it’s made me think.

Last summer, my father in law killed himself. I haven’t really talked to anyone about it. Not my wife, not my mother in law. Not my own friends or family. My wife found his legs sticking out from the closet in the master bedroom one morning. I rushed over to their house outside the city and waited in the front yard as the coroner arrived and cops continued to waltz in and out of the house. As they wheeled him out in a bodybag on a stretcher, I asked to see him. Call it morbid curiosity, but at the same time, I felt almost an obligation to him. I married his daughter and she would never see him again, so maybe it was up to me to carry on that final memory, for her sake? In case she ever wanted to know?

After they took his body away, I was left at the house to keep an eye on things. A relative had paid for a hazardous waste disposal company to come by and clean up the mess he left behind. Someone had to watch them right? What do you do in that situation? I sat on the edge of the bed for a few minutes, staring into the pool of blood in the closet where he shot himself. He put towels down. Despite being dramatically intoxicated, he took the time to make it “easier” for whoever was left to clean up the mess. There was something respectable about that.

The waste disposal team finally arrived. Not what I expected at all. It was an older couple in their late fifties, with a big pickup truck pulling a plain white enclosed trailer full of cleaning supplies, power tools, and even a few sheets of sheetrock. It makes sense when you think about it. Everything with blood on it has to be cleaned or removed. They were nice people. They’d obviously been doing it a long time. It took them a few hours to comb through the clothes in the closet, remove the ones with blood, and then rip up the carpet and the subfloor after soaking the blood with cat litter. Then they were gone. I was left alone in a dark house, with an few square feet of carpet missing in the master bedroom closet.

Again, I mentioned at the beginning I wasn’t sure where this was going. I live in that house now. My wife and I moved in to help her mom with the mortgage and the bills. Sometimes it’s weird to walk past that bedroom and think about what happened; about what I saw. It’s a small thought in the back of my mind at all times. An ever present darkness. I feel like that’s a book I read somewhere…

So maybe it’s just that? You see all the shit on the news about all the terrible things that happen in our world and they remind you of your own dark thoughts. But that’s part of being human right? Knowing that all of this is temporary; that it happens to everyone. I find comfort in that I think. That someone, somewhere is struggling to find meaning in the same things that I don’t understand. Maybe that person is you.

If you want to talk, reach out to me on Twitter, or a leave a comment if I still have those enabled. I honestly can’t be bothered to check right this second. I don’t think I’m in a “dark place” right now, just a difficult one, and maybe you are too. I think I’m gonna take a trip down to the coffeeshop and try to get some work done, drink some tea, try to find something useful in my own thoughts. Let me know if you find something useful in yours.

Converting a WordPress Plugin Store to HTTPS

A few weeks ago, I was experimenting with https:// on the site for my plugin, ACF Widgets. I added the SSL cert for my domain using Let’s Encrypt and the requests were being handled fine, but I was only enforcing SSL on the checkout page. If you hit the ACF Widgets site with https:// initially, everything worked fine, but my login rules were causing some issues with people logging in to the support forums.

After 4 or 5 people contacted me through other channels telling me they couldn’t log in to get support, I decided to look into it a little more closely. As it turns out, the login pages were trying to work over SSL while people were trying to login with insecure http:// POST requests. Whoops!

To fix this problem, I needed to convert the whole site to use https:// all of the time. This too worked out fine and wasn’t an issue. 3 lines in .htaccess that you can find on a million different blogs. Super easy stuff. What made things more difficult, was upgrading the URL for my plugin to check and receive automatic updates.

The problem with copying .htaccess rules

I think this goes back to a fundamental flaw with humans, in that we want results and we want them immediately. In 99% of the tutorials I found, most of them advocated for an .htaccess rule that looks something like this:

Generally, this will work, and it’s fine. Let’s go through it line by line.

  1. Turn the Rewrite Engine on. This tells apache that we’re going to do a rewrite so it can load the required modules.
  2. Set a condition. In this case, return true if the server is listening on port 80. (The standard port for HTTP)
  3. Redirect the request to the given URL and pass in the URL query parameters.

Like I said, for most sites this works fine. However, when I pushed the next update to my plugin, I noticed I wasn’t getting any update notices. Why wasn’t it working?!

Now, in my most recent plugin update, I updated the store URL to my new https:// domain, so after everyone updated, I know whatever weird issue going on would probably go away. I did some tests and sure enough, requesting the update using the https:// store URL triggered an update. So why wasn’t it working with the http:// URL? What was happening during the redirect that broke things?

Since I have almost 500 customers, sending an email asking everyone to manually re-install this new version of my plugin was unacceptable. I knew I could do better. I decided to dig-in to the inner workings of APACHE and HTTP a little bit to understand what was going on behind the scenes.

A brief history of redirects in HTTP

So from my understanding of reading numerous blogs, is that the original intent of the HTTP/1.1 spec, was that if no redirect status code was specified (ie. 301, 302, etc) that the client was supposed to treat it as the same method as the original request. So if I send a POST request to /my-api-endpoint/ , the client should honor that POST request and it’s data if I do not specify a status code. In APACHE’s mod_rewrite this looks like:

RewriteRule ^(.*)$$1 [R]

Using the [R] flag with no options.

Somewhere along the way (I’ve seen both IE and Netscape blamed) browsers and HTTP clients in popular languages begin to interpret any missing status code as a 302. In the HTTP spec, a 302 request is for GET requests only. Herein lies the problem with our updates.

EDD Software Licensing Update Process

To understand why updates are failing, I also needed to examine the source code for the update script I was using. At the time of this writing, ACF Widgets is build upon Easy Digital Downloads and the Software Licensing Add-On. It works great! Though in my case, updating the store to https:// was obviously causing issues. Digging in to the code, we find this:

And herein lies our problem. EDD SL uses wp_remote_post() to send API requests to the URL of our plugin store, which is fine, nothing wrong with that. However, when our POST request to our EDD store encounters a redirect without a specified status code, cURL redirects to a GET request for the homepage with no query parameters. Since that’s obviously not what we want, the EDD SL update script fails silently (like it should) so we don’t clutter the users dashboard with errors in case our store is down for any reason. In our case though, we want to preserve that POST request and any data we send. So how do we do that?

Enter the Magical Hero Extraordinaire Status Code™, 307

According to HTTP Status Code Spec, a 307 code should behave thusly:

The requested resource resides temporarily under a different URI. Since the redirection MAY be altered on occasion, the client SHOULD continue to use the Request-URI for future requests. This response is only cacheable if indicated by a Cache-Control or Expires header field.

Perfect! That’s exactly what we want! In short, this will preserve our POST request and any data we send. So now we can use this in conjunction with a normal 301 request to route all of our traffic through our newly secured domain.

So line by line, let’s go through this new .htaccess.

  1. Turn on Rewrite Engine
  2. Check for a request on port 80
  3. Check for the GET request method
  4. Redirect (via a 301 for SEO purposes) and ignore all other rewrite rules ([L] flag).

Now if we don’t have a GET request (maybe we have an API that uses PUT, POST, or DELETE) it will get routed through the second rule.

  1. Check for a request on port 80.
  2. Perform a 307 redirect, thus preserving our request method and data. Also, ignore any more rewrite rules ([L] flag).

Now for those of you worried about SEO, don’t worry. Google only cares about your visible stuff, AKA GET requests. You shouldn’t get a penalty for other request types (because Google won’t even know to access them).

As you can see, 307 redirects can be extremely powerful. With the correct caching headers, you can even instruct clients to cache the results while you update your API or tools to use your new secured endpoints, without sacrificing security.

So what next?

Since we now have a our store properly configured to redirect requests from plugins out in the wild, there isn’t anything else to do except wait. Customers will update the plugin to the new version which uses the new https:// store endpoint. If you have detailed stats about version usage for your plugin, you could eventually remove the redirect, though I don’t see a reason to for the vast majority of plugin stores out there. If anything, it’s a good catch all for anything you may add in the future and forget about.

Modifying Custom Taxonomy Forms in WordPress

Today, I was working on a client project and needed to add a little snippet underneath a hierarchical taxonomy form that was registered on a custom post type. Unfortunately, after spending about ten minutes digging through core and googling, I couldn’t find an action hook to use. Luckily, after tracing the output a little further back, I found what I was looking for.

Publishing A WordPress Plugin without SVN, Utilizing Ship

So just this past week, I submitted my first plugin to the plugin repository. Needless to say, it was an exciting (yet dull) experience! Since I’m still fairly green to professional development as a whole, there were some aspects of the .org publishing process that were confusing, so I’m writing this post in hopes that someone will find it useful. 🙂

Adding a custom style button in the WordPress post editor

So my title is a little misleading as what we’re creating is largely based on what your definition of a button. However, the point still stands 🙂

Here is an example of what we’ll be creating today.

Crafting Personalized HTML E-Mails with wpMandrill

Recently, I’ve been working on a new little side project called ToDo, a small SPA that allows you to create and manage a ToDo list. It utilizes the new WordPress JSON REST API and it’s awesome. You should definitely check it out!

Edit: ToDo in its current form has unfortunately been “closed”. While you may still find something at the link, I’m not doing anything with it, and will be replacing it with something new, hopefully, in the very near future.

Why WordPress 4.2.3 should have been a non-issue.

Let me preface the following post by saying this: I am sorry if your site was affected by the WP 4.2.3 update. I’m sure nobody on the core team wanted things to break and if they could go back in time and do things differently, then I think they would.

What happened?

So for the uninformed, on July 23, 2015 the WP core team released a security update that was installed to millions of websites via automatic updates. For a lot of people, this was fine and they weren’t affected by the change. However, another group of sites (some would argue a large portion) were broken due to breaking changes in the WP Shortcode API. This isn’t a post about the shortcode API or the vulnerability though. You can read about the update on the Make WP Core blog.

Why things should not have broken.

Take this section as a grain of salt, and recognize it as my opinion. You don’t have to agree, and I don’t expect everyone too. 

I have been developing on the WordPress platform for about 3 years now. I currently work for a small digital marketing agency in Northern Kansas as the sole developer creating websites for our clients. Before I started working here,  the previous developer had built a lot of sites using premium themes from Themeforest, which as we all know, usually include a bunch of shortcodes for inserting content and functionality across the site. After doing support for a few of these clients, I quickly realized that shortcodes were not a solution for displaying content for our clients. Not only were they messy and difficult for clients to understand (in some instances) but they created a dependency that I was not comfortable with on such a widespread scale. A client accidentally deactivating a plugin could remove some core pieces of content; it was something I just wasn’t comfortable with.

I started to build out themes for our clients using _S and designs from our in house designer. I jumped onto the ACF bandwagon just before the release of v5 and have been using the Pro version on all of our clients’ sites with great success (Elliot’s commitment to backwards compatibility is another post for another time). ACF allowed me to create highly customized interfaces for our clients, while utilizing an API that would work regardless of if ACF was activated or installed (check out Bill Erickson’s post about removing dependencies from ACF). Over time, I have migrated some clients over to a more customized solution when they would come to us after having difficulty manipulating shortcodes and they have loved it.

Now I know what you’re thinking, “But Daron, using ACF ties you to a theme and that’s bad if you’re a blogger who likes flexibility!” And you’re right. Tethering some clients to a specific theme just isn’t an option, but that isn’t an excuse to build solutions that are fundamentally flawed. One of the use cases that really blew my mind, was how people were outputting and manipulating URLs via shortcode. A much better approach would have been to use custom fields and post meta and then calling that data from the theme. Another alternative would be to build a custom plugin with a simple admin interface and some custom metaboxes.

In the Make WP post, Andrew mentioned how people were using the shortcode API in ways that it was never intended for. You don’t need to look any further than the default [gallery] shortcode to see what the core team was talking about. The gallery shortcode is completely self contained. It outputs it’s own HTML and any attributes needed to attach styling to. If you’re building shortcodes to output a link to an image or to a URL, then you’re fundamentally using shortcodes in the wrong way. Using actions and filters, you can display all sorts of things in and around the_content. If you need to link a background image, you should be using the customizer or a custom field/metabox. For one, using a custom metabox is a vastly superior UX as well as giving you the peace of mind that sites won’t break because of a fundamentally flawed implementation. The shortcode codex entry does not mention using shortcodes as a replacement for HTML attributes and it probably never will. If you’re site needs to be that customizable, you should be using custom fields and metaboxes.

If you want to remove the theme dependency from solutions like ACF and CMB2, use a hook and display that data programatically. This is a totally valid way to show custom content:

Just pop that into a plugin file and you’re off to the races. If you need more programatic control over where content is displayed, then you should look into developing a custom theme or using a more inclusive shortcode. Note, the $extra_content variable should include all of the HTML necessary to support itself. You can enqueue CSS as needed from the plugin as well.

Here is another example that was specifically mentioned in the Make WP article and a workaround that doesn’t require hacking a theme.

Using the above snippet, you can wrap the_content in a div and apply a background image to that div. Using CSS you can further position the image how you want. You can even include that CSS in the same plugin, thus removing any theme dependency.

In closing

We as developers are responsible for when things break and it’s only in our best interest to use the tools that we are given to build applications and solutions that will stand the test of time. Hacking APIs is never a good solution to a problem and it’s up to us to use some common sense and read the documentation on the intended uses of the software that we leverage everyday. Sure, people will always find new ways to use software that the developers never intentioned, however, you do not have the right to be upset when you’ve implemented an unofficial workaround for a problem that is easily solved by utilizing other techniques and APIs. The core team did everything they could to avoid breaking things. Problem is, it’s impossibly to foresee every possible unofficial use-case for every API in the software. Stop giving them flack for your experimental implementations of the API.

I know this probably seems like a disorganized rant, and in some ways, it probably is, but I needed to get it out there and off of my mind. Leave a comment if you want to continue the discussion or you can tweet me @Daronspence

An Ode to More Blogging & WordPress 4.2

Like a lot of other folks in the community, I think the new year (ha! It’s April!) is a great time to make new goals in how we approach our daily lives. So in the spirit of the community, I’m going to try and blog more this year. I’m gonna shoot for a minimum of once a week, though I would like to make it 3+ times a week.

If you happen to be reading this, tweet me some encouragement! I would love to hear it 🙂

As a side note, I’m going to start running the WordPress beta plugin on this site. Should be exciting!
