Classe XoopsModule

Definizione Classe

class XoopsModule extends XoopsObject
{
    // Proprietà
    public $modinfo;      // Array info modulo
    public $adminmenu;    // Voci menu admin

    // Metodi
    public function __construct();
    public function loadInfo(string $dirname, bool $verbose = true): bool;
    public function getInfo(string $name = null): mixed;
    public function setInfo(string $name, mixed $value): bool;
    public function mainLink(): string;
    public function subLink(): string;
    public function loadAdminMenu(): void;
    public function getAdminMenu(): array;
    public function loadConfig(): bool;
    public function getConfig(string $name = null): mixed;
}

Proprietà

Proprietà	Tipo	Descrizione
mid	int	ID Modulo
name	string	Nome visualizzazione
version	string	Numero versione
dirname	string	Nome directory
isactive	int	Stato attivazione (0/1)
hasmain	int	Ha area principale
hasadmin	int	Ha area admin
hassearch	int	Ha funzione ricerca
hasconfig	int	Ha configurazione
hascomments	int	Ha commenti
hasnotification	int	Ha notifiche

Metodi Chiave

// Ottieni istanza modulo
$module = $GLOBALS['xoopsModule'];

// O carica per dirname
$moduleHandler = xoops_getHandler('module');
$module = $moduleHandler->getByDirname('mymodule');

// Ottieni info modulo
$version = $module->getVar('version');
$name = $module->getVar('name');
$dirname = $module->getVar('dirname');

// Ottieni configurazione modulo
$config = $module->getConfig();
$specificConfig = $module->getConfig('items_per_page');

// Verifica se modulo ha funzionalità
$hasAdmin = $module->getVar('hasadmin');
$hasSearch = $module->getVar('hassearch');

// Ottieni percorso modulo
$modulePath = XOOPS_ROOT_PATH . '/modules/' . $module->getVar('dirname');
$moduleUrl = XOOPS_URL . '/modules/' . $module->getVar('dirname');

XoopsModuleHandler

Definizione Classe

class XoopsModuleHandler extends XoopsPersistableObjectHandler
{
    public function create(bool $isNew = true): XoopsModule;
    public function get(int $id): ?XoopsModule;
    public function getByDirname(string $dirname): ?XoopsModule;
    public function insert(XoopsObject $module, bool $force = false): bool;
    public function delete(XoopsObject $module, bool $force = false): bool;
    public function getList(?CriteriaElement $criteria = null): array;
    public function getObjects(?CriteriaElement $criteria = null): array;
}

Esempi di Utilizzo

// Ottieni handler
$moduleHandler = xoops_getHandler('module');

// Ottieni tutti i moduli attivi
$criteria = new Criteria('isactive', 1);
$activeModules = $moduleHandler->getObjects($criteria);

// Ottieni modulo per dirname
$publisherModule = $moduleHandler->getByDirname('publisher');

// Ottieni moduli con admin
$criteria = new CriteriaCompo();
$criteria->add(new Criteria('isactive', 1));
$criteria->add(new Criteria('hasadmin', 1));
$adminModules = $moduleHandler->getObjects($criteria);

// Verifica se modulo è installato
$module = $moduleHandler->getByDirname('mymodule');
if ($module && $module->getVar('isactive')) {
    // Modulo è installato e attivo
}
