Créer une table dans un plugin personnalisé lors de son activation?

J'essaie de créer un plugin personnalisé où je veux créer une table lorsque le plugin est activé. J'ai essayé le code suivant mais il ne crée pas la table dans la base de données

function create_plugin_database_table() {
 global $wpdb;
 $table_name = $wpdb->prefix . 'sandbox';
 $sql = "CREATE TABLE $table_name (
 id mediumint(9) unsigned NOT NULL AUTO_INCREMENT,
 title varchar(50) NOT NULL,
 structure longtext NOT NULL,
 author longtext NOT NULL,
 PRIMARY KEY  (id)
 );";

 require_once( ABSPATH . 'wp-admin/includes/upgrade.php' );
 dbDelta( $sql );
}

register_activation_hook( __FILE__, 'create_plugin_database_table' );

Vous devez inclure le fichier wpadmin/upgrade-functions.php pour créer un exemple de tableau.

function create_plugin_database_table()
{
    global $table_prefix, $wpdb;

    $tblname = 'pin';
    $wp_track_table = $table_prefix . "$tblname ";

    #Check to see if the table exists already, if not, then create it

    if($wpdb->get_var( "show tables like '$wp_track_table'" ) != $wp_track_table) 
    {

        $sql = "CREATE TABLE `". $wp_track_table . "` ( ";
        $sql .= "  `id`  int(11)   NOT NULL auto_increment, ";
        $sql .= "  `pincode`  int(128)   NOT NULL, ";
        $sql .= "  PRIMARY KEY `order_id` (`id`) "; 
        $sql .= ") ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ; ";
        require_once( ABSPATH . '/wp-admin/includes/upgrade.php' );
        dbDelta($sql);
    }
}

 register_activation_hook( __FILE__, 'create_plugin_database_table' );

Ce code fonctionne pour moi:

function installer(){
    include('installer.php');
}
register_activation_hook( __file__, 'installer' );

Puis installer.php:

global $wpdb;
$table_name = $wpdb->prefix . "my_products";
$my_products_db_version = '1.0.0';
$charset_collate = $wpdb->get_charset_collate();

if ( $wpdb->get_var( "SHOW TABLES LIKE '{$table_name}'" ) != $table_name ) {

    $sql = "CREATE TABLE $table_name (
            ID mediumint(9) NOT NULL AUTO_INCREMENT,
            `product-model` text NOT NULL,
            `product-name` text NOT NULL,
            `product-description` int(9) NOT NULL,
            PRIMARY KEY  (ID)
    )    $charset_collate;";

    require_once( ABSPATH . 'wp-admin/includes/upgrade.php' );
    dbDelta( $sql );
    add_option( my_db_version', $my_products_db_version );
}
