Add HTML to Content and Return it Back
Lab: PHP Output Control and Buffer Basics
Video Runtime: 13:38
There are a lot of use cases where we want to add HTML, continue processing, and then render it out to the browser. WordPress has multiple filter events that let us tap into the process just before it goes out. It gives us the ability to change it. One example is when you call the function the_content(). There is a filter with the same name.
In this episode, you’ll use the companion plugin you installed in the last episode. Then you’ll add more HTML to the content. Next, I’ll show you the way I see so often which is like this:
| add_filter( 'the_content', __NAMESPACE__ . '\add_markup_to_content' ); | |
| function add_markup_to_content( $content ) { | |
| $html = '<div class="entry-content-container" itemprop="text"><div class="wrap">'; | |
| $html .= $content; | |
| $html .= '</div></div>'; | |
| return $html; | |
| } |
You’ll use the PHP output buffer and move the HTML into a view file to separate it from the business logic. Let’s do this together, step-by-step.
