New print_h5p_content filter

[arzola]

I added a custom filter print_h5p_content to be able to hook the h5p HTML content wrapper creation, this could be useful to modify the wrapper of each h5p activity.

Problem

There is no a way to modify the HTML output for each h5p activity

Solution

We need to create a specific anchor link to each h5p activity, currently the h5p-iframe-wrapper uses h5p-iframe-' . $content['id'] to identify each activity however we need a unique identifier so it could be solved adding an extra wrapper.

We think this could be useful for other developers to modify the HTML output in a clean way.

Example

add_filter('print_h5p_content', function($content) {
    return '<div class="customWrapper">'.$content.'</div>';
});

We think this could be a good addition to the plugin :) Thank you
