Question

我想从用户名中获取Joomla用户ID，我将在外部脚本中使用它。

Answer 1

如果你不想通过Joomla获取它，只需使用这样的SQL语句：

SELECT id FROM #__users WHERE username = 'someusername';

或者加载Joomla并使用类似这样的代码：

if (!defined('_JEXEC')) {
    define( '_JEXEC', 1 );
    define ('JPATH_BASE', "c:\\wamp\\www\\oursite");
    define( 'DS', DIRECTORY_SEPARATOR );
    require_once ( JPATH_BASE .DS.'includes'.DS.'defines.php' );
    require_once ( JPATH_BASE .DS.'includes'.DS.'framework.php' );
    require_once ( JPATH_BASE .DS.'libraries'.DS.'joomla'.DS.'factory.php' );
    require_once ( JPATH_LIBRARIES.DS.'joomla'.DS.'import.php'); // Joomla library imports.
    $app=& JFactory::getApplication('site');
}

$db = JFactory::getDbo();
$query = $db->getQuery(true);
$query->select('id');
$query->from($db->quoteName('#__users'));
$query->where($db->quoteName('username')." = ".$db->quote('someusername'));
$db->setQuery($query);
$user_id = $db->loadResult();

// Get a JUser object, if you want/need it
$user = JFactory::getUser($user_id);

如何从用户名获取Joomla用户ID（这是一个数字）？
