Build the Shortcode Processer

Let’s build the shortcode processor. This is the function that is called when the shortcode is found in the content. WordPress will call our function.

In our plugin, we are going to use one function for both shortcodes.

We’ll do a deep discussion on how to prepare and process the hidden content. First, we talk about why we are not sanitizing it at this point. We’ll talk about why, when, and how WordPress sanitizes. We’ll talk about processing other shortcodes that are embedded within our hidden content.

Next, we need to define our file’s namespace and specify the real fully qualified path to our function. Let me introduce you to PHP __NAMESPACE__.
