Time Off 2019: Part 3 of 4 of Social Media Sabbaticals (No Time for Four)

December 4, 2019 / Tom

If you’ve followed along with the previous articles this year, you’ll notice that I didn’t actually take time off each quarter.

As I head into December of this year, this will be the final – and obviously the third – time I take off the social web for the remainder of the year. At least that’s the plan. I’m thinking of doing it a little bit differently this year.

For those of you who haven’t read about my doing this in years past, check out:

Though I don’t really do year in review posts, going back to read these and see how things have panned out over the years is always fun and is as close to retrospectives as I get.

With all of that said, I’d summarize the entire year by saying: It’s been a year, if nothing else. Some ways bad, some was fantastic.

On Retiring Site Memberships

November 26, 2019 / Tom

After two years after writing a lot of content and giving exclusive access to site members, this past weekend I opened the site to everyone.

In short:

But this wasn’t a small nor was it a quick decision and it’s not something that I opted to on a whim. For those who were subscribed to the newsletter earlier this year, I made an announcement that this was coming.

You Should Be Using PHP Filtering Functions, Part 2

November 19, 2019 / Tom

In the previous post, I talked about the reasons using PHP filtering functions is more useful rather than not.

In short, doing so helps to provide a level of validation that’s built into the language so that we don’t have to re-write something. Naturally, there are caveats.

For example, if you’re having to validate a value that is of non-Latin characters, then you’re going to go have to go it alone and implement validation with perhaps a regular expression.

But if you’re using email addresses, URLs, numbers, IP addresses, and so many more things, then you’re in a good position to use something that already exists.

Anyway, all of the above is still about filtering variables. What about inputs, though? That is, those that come from $_POST or $_GET. It’s possible to use a similar strategy with a different function and different filter set.

But if you understand the basics presented in the last post, then this post will not be very different.

You Should Be Using PHP Filtering Functions, Part 1

November 14, 2019 / Tom

I’ve talked about data sanitization in WordPress in previous posts. This is a topic that’s important not only for those of us working to build solutions for others in WordPress, but also for those who are writing code that will directly interact with a database via PHP.

Sure, there are native WordPress functions to make this process easier, but there are also built-in PHP filtering functions to help with this. Namely filter_var and filter_input and these are things that I think are helpful for PHP developers to know.

Search Post Metadata in the WordPress Admin Area

November 7, 2019 / Tom

After you’ve worked with WordPress for any extended amount of time, it’s likely that you’ve worked with post metadata in some capacity. Perhaps you’ve simply read metadata from the database, or maybe you’ve both written to and read from the database table, as well.

It can be a really powerful API whenever you need to associate certain information with your posts (or, if you’re into abstracting things even more, to your models).

That said, what happens when you want to include information from the metadata table but don’t have the convenience of plugins such as SearchWP or Relevanssi?

Furthermore, assume the use case is just for administrators and it’s only for the administration area of WordPress. That is, you want to search your posts from within the All Posts screen but you want to include the post metadata in the search criteria, as well.

What then?
