Tag: WordPress (Page 141 of 220)

With Mayer about to turn a year old (they grow up so fast), with a healthy backlog of features sitting in the queue, and with two other themes sitting in the planning stage for the first part of this year, I’ve been thinking a bit about WordPress themes as a whole.

Sounds like I have too much free time doesn’t it?

But seriously, one of the things that I do wonder about is how long a WordPress theme can actually be sold and continue to be viable for users especially since design trends change. Additionally, I think that there are times in which a theme has reached the maximum number of features it can justifiably offer before it just begins to feel a bit crowded.

Given the state of many modern web applications, one of the things that I think surprises many developers when coming to WordPress is that the application is stateless.

That is, it doesn’t maintain any type of session using the conventional PHP $_SESSION utilities. If you’re building a web application on top of WordPress where users will be required to login, you may want to introduce something like this.

At the very least, you may be interested in using cookies to manage certain settings for users who have signed in on the front-end using some type of custom functionality you’ve built.

To that end, here’s how to set cookies in WordPress.

When it comes to searching the WordPress database, there’s probably no better API than WP_Query. That doesn’t mean it’s not without it’s limitations, though (only which will be improved over time, I’m sure).

For example, consider the case where you have two types of meta data that are completely unrelated and you need to run a search for both of them. Essentially, you have WP_Query and multiple meta keys that you need in order to search for information from this database.

In this specific case, I’m not talking about a single piece of meta data that has multiple keys and that would support and AND or and OR clause.

Instead, I’m talking about the idea of having multiple meta keys each of which are associated with a given post, but must all be searched in order to find the posts that have the data associated with it.

In more technical terms, I’m looking for the intersection of post IDs all of which share a common set of multiple, unrelated meta keys.

In yesterday’s post, I shared how to determine if a given term has a child term. The idea behind doing this is to check to see if a given WordPress term has a child and if the child is actively applied to the post (or post type) in question.

But there’s a caveat that I didn’t mention:

Just because a term has a child doesn’t mean the term itself is actually active.

This means that you could technically be getting a false positive if you’re using the previous method as your sole means to determine if a term has a child. Instead, you need to do one more thing: Check to see if the post has the term applied to it.
