Custom HTML

The custom HTML field allows you to output anything. You can even use a PHP callback function to output the HTML.

This field is usually used to display custom messages/instructions to users. Sometimes, it's used with PHP callback to display more advanced content (such as content from a query).

Settings​

Besides the common settings, this field has the following specific settings, the keys are for use with code:

NameKeyDescription
ContentstdThe custom HTML content.
PHP CallbackcallbackThe PHP function that shows the custom HTML content. Optional.

This is a sample field settings array for registering this field with code:

[
    'type' => 'custom_html',
    'std'  => '<div class="alert alert-warning">This is a custom HTML content</div>',
],

Styling​

Because this field is usually used to display custom content, it requires some CSS to make the content looks good. To enqueue a CSS file to the admin editing page, use the rwmb_enqueue_scripts hook:

add_action( 'rwmb_enqueue_scripts', 'prefix_enqueue_custom_style' );
function prefix_enqueue_custom_style() {
    wp_enqueue_style( 'style-id', get_template_directory_uri() . '/css/admin.css' );
}

And in the admin.css you can put your custom styles.
