Basic Shortcodes

Add a Shortcode

It is possible to add your own shortcodes by using the Shortcode API. The process involves registering a callback $func to a shortcode $tag using add_shortcode().

add_shortcode(
    string $tag,
    callable $func
);

[wporg] is your new shortcode. The use of the shortcode will trigger the wporg_shortcode callback function.

add_shortcode('wporg', 'wporg_shortcode');
function wporg_shortcode( $atts = [], $content = null) {
    // do something to $content
    // always return
    return $content;
}

Remove a Shortcode

It is possible to remove shortcodes by using the Shortcode API. The process involves removing a registered $tag using remove_shortcode().

remove_shortcode(
    string $tag
);

Make sure that the shortcode have been registered before attempting to remove. Specify a higher priority number for add_action() or hook into an action hook that is run later.
