How to use Customize API “postMessage” Method for Color Options

customizer-color-option-postmesssage

I’m not actually a fan of themes with tons of design options. I think as a designer, it’s our job to design theme.

However, it’s not always a bad idea to let user express their creativity.

Last weekend, I create another theme. Nevertheless, a simple one with classic design. And this time I create several color options for it. Usually I prefer “refresh” transport method for my themes, because it’s works, easier to code (and maintain in the future). But because this is a simple theme, I get it done relatively quickly. So I decide to “play” and use “postMessage” transport method for the color options.

There are problems I found when implementing this, and I want to share my solution.

Here’s the theme, you can download and check the source code:

Admin-Color-X

Well, there was a time when I need to remove admin color scheme option. And this how I do that.

It’s actually pretty simple. And I will also explain the coding process, how to learn to code something in WordPress. (I’m sure it’s pretty useful trick if you wants to learn to code/problem solving in WP). Read More How To Remove WordPress Admin Color Scheme Option

That was actually a question by a fellow WordPress designer/developer when he realized his code didn’t work (I’ll explain the problem below).

It’s actually a simple mistake and can be avoided if we use “refresh” transport method when creating customizer option. But I do understand that “postMessage” transport method is better (but needed more code).

So here’s a little example. I create a twentyfifteen child theme with customizer setting to hide/show header area. Read More How to use Customize API “postMessage” Method to Hide/Show Element

plugin-activation-notice-example

Adding admin notice on plugin activation can be super useful. For example we can:

  • Add link to the settings page,
  • Giving info about minimum requirement of their server,
  • Tutorial links,
  • Promote pro version of our plugin,
  • Ask the user to rate our plugin,
  • Ask donation,
  • Or simply telling them that they are awesome.

If you ever try to create an “Admin Notice” on plugin activation. You’ll know that using admin_notices action inside your “activation hook function” will not work. But there’s a workaround for that. Read More How to Create Admin Notice On Plugin Activation

Additional-Reading-Settings

It’s very easy to create settings page in WordPress. But sometimes in our plugin we only need a single/few options. And creating dedicated settings page just for this option is overkill.

That’s what I think when I write “f(x) Private Site” Plugin yesterday. You can download the plugin for a full code example:
