Dynamically create shortcodes using add_shortcode and a callback

In the example below, $shortcodes is a multidimensional array with shortcode data.

foreach( $shortcodes as $shortcode ) {

    // Here we have the shortcode name, could be 'custom_person_john'.
    $shortcode_name = $shortcode['slug'];

    // Anonymous function should be referred to as 'custom_person_john'.
    $shortcode_name = function( $shortcode ) {

      // Build shortcode attributes.
      $atts = shortcode_atts( array(
        'name' => 'john',
        'type' => 'mammal'
      ), $atts );

      $markup = '<div class="'.$atts['name'].'">';
         $markup .= '<div>';
            // $shortcode should contain custom markup from the array.
            $markup .= $shortcode['html'];
         $markup .= '</div>';
      $markup .= '</div>';

      return $markup;

    };

    // Trying to register the shortcode
    add_shortcode( $shortcode['slug'], $shortcode_name( $shortcode ) );

};

So this is not working, but I can’t grasps why. If I dump all the registered shortcodes, they don’t show up in the list. Trying to load them simple echo’s [custom_person_john]. I don’t have errors either.

Edit: If anyone has other ideas on how to create them dynamically out of an array, feel free to suggest 🙂

the shortcodes doesn’t shop up in the liste because it’s not a valid declaration with a valid function callback on the 2nd argument

try this to see what append :

// shortcode data

add_filter("shortcode_list", function ($shortcode_list) {
    $shortcode_list["slugA"] = array(
        "html" => "test html 1",
    );

    return $shortcode_list;
});

add_filter("shortcode_list", function ($shortcode_list) {
    $shortcode_list["slugB"] = array(
        "html" => "test <strong>html 2 - [slugA]</strong>",
    );

    return $shortcode_list;
});


// shortcodes declaration

add_action("init", function () {

    $shortcodes = apply_filters("shortcode_list", array());

    foreach (array_keys($shortcodes) as $shortcode_slug) {
        add_shortcode($shortcode_slug, "shortcode_callback");
    };

});


// callback function

function shortcode_callback($atts, $content = "", $tag) {

    // Build shortcode attributes.
    $atts = shortcode_atts( array(
        'name' => 'john',
        'type' => 'mammal'
    ), $atts);


    // shortcode data
    $shortcodes = apply_filters("shortcode_list", array());
    $shortcode = $shortcodes[$tag];


    // construct result of the shortcode

    $markup  = "";
    $markup .= '<div class="'.$atts['name'].'">';
        $markup .= '<div>';
            // $shortcode should contain custom markup from the array.
            $markup .= $shortcode['html'];
            //$markup .= do_shortcode($shortcode['html']); // to replace shortcodes in the "html" data


            $markup .= '<pre>';
            $markup .= print_r($atts, TRUE);
            $markup .= '</pre>';

        $markup .= '</div>';
    $markup .= '</div>';

    return $markup;

}
