Personal opinions and how-to’s that I’ve written both here and as contributions to other blogs.

Reading and Understanding WordPress Error Logs, Part 2

July 25, 2018 / Tom

Last time, we walked through the following:

configuring debug constants,
locating an error log file,
understanding how to read the log file,
understanding stack traces
understanding how to read the stack

As nice as that is, it’s still important to understand how to write data to error log from a programmatic aspect. That is to say; it’s one thing if your work throws errors, warnings, or notices.

Understanding WordPress Error Logs

It’s another thing if you want to understand how to write information to the file for research and debugging manually.

In this post, we’ll continue doing exactly that to further our understanding WordPress error logs.

The Second Social Media Sabbatical of 2018

July 24, 2018 / Tom

As I’ve been writing this post, I’ve felt so pretentious when it comes to using the word “sabbatical” as it relates to something like social media.

I mean, I’ve always associated sabbaticals as something that professors, academic types, religious leaders, and higher-ups take. Not just an average dude who makes a living on the Internet.

Sabbatical or a sabbatical (from Hebrew: shabbat (שבת) (i.e., Sabbath), in Latin: sabbaticus, in Greek: sabbatikos (σαββατικός), literally a “ceasing”) is a rest from work, or a break, often lasting from one month to a year.

But I suppose, by that definition, it makes sense, right?

Anyway, I started the trend earlier this year, it went well, and I want to keep a consistent theme going at least for 2018, so why stop it during just the second time through?

Reading and Understanding WordPress Error Logs, Part 1

July 19, 2018 / Tom

As we continue looking at what it means to be an independent WordPress developer, the tools needed, and the various strategies that can improve our skillset, I’ve been talking through the various constants, plugins, and tools to help us.

If you’re just stumbling across this post, then I recommend checking out my guide to native WordPress debugging tools as well as the rest of the posts in the series thus far.

After all, I find it important that we’re all working off of the same foundation – or something closely related – when going through this information.

Understanding WordPress Error Logs: Xdebug

Ultimately, using a tool like Xdebug is indispensible, but we have to work up to that (for those who are curious, I wrote a brief guide about this a little over a year ago).

For now though, let’s start with the basics. In the previous post, I left with the following statement:

In the next post, we’ll start looking at what’s necessary to examine the error log that’s generated by WordPress and how to understand the information we see.

And that’s what I want to look at today because, if nothing else, it will give you something practical off of which to work.

What’s the Purpose of a Boilerplate?

July 17, 2018 / Tom

Regardless of the library, framework, or code with which you work, you’re likely going to encounter the concept of a boilerplate at some point.

There are a handful of them for WordPress, right 🙃?

But it seems to be an increasingly popular trend that people are creating more and more boilerplates, which isn’t inherently a bad thing, but that there may be confusion as to the purpose of a boilerplate.

So, as defined by Wikipedia (which I think offers a great definition):

In computer programming, boilerplate code or boilerplate refers to sections of code that have to be included in many places with little or no alteration. It is often used when referring to languages that are considered verbose, i.e. the programmer must write a lot of code to do minimal jobs.

But notice there’s a phrase that should not be missed. Specifically:

…that have to be included in many places with little or no alteration.

And in some observations I’ve seen within the WordPress economy, at least, boilerplates seem to require that code be removed, modified, or stripped away rather than simply included or added.

That’s what I hope to clarify.

Using the Registry Pattern in WordPress

July 12, 2018 / Tom

I’ve had a few conversations with various friends and others on Twitter about the notion of global variables in programming languages. For those who are new to programming or who are unsure as to why they are bad:

The use of global variables makes software harder to read and understand. Since any code anywhere in the program can change the value of the variable at any time, understanding the use of the variable may entail understanding a large portion of the program.

This isn’t to say they don’t have their use, but if you’re interested in object-oriented programming (especially in a WordPress setting where you’re going to be using PHP), then it’s important to understand some better alternatives than global variables.

That is, there are ways to work with passing data around your application without the need for global variables. And one such way is the registry pattern.
