JFactory::getUser with username - Joomla! Forum - community, help and support

hello,

newbie here.

joomla! 2.5.8 - platform 11.4.0
php 5.4.8

i trying access user's information based on username. using following user object.

code: select all

$getuser = jfactory::getuser('angrybird');

per joomla! docs-

if string passed interpreted user name , converted integer id automatically.

my code above not user's information.

by examining getuser() code in factory.php, string parameters, execution gets

if ($current->id != $id)

.

code: select all

public static function getuser($id = null)
   {
      if (is_null($id))
      {
         $instance = self::getsession()->get('user');
         if (!($instance instanceof juser))
         {
            $instance = juser::getinstance();
         }
      }
      else
      {
         $current = self::getsession()->get('user');
         if ($current->id != $id)
         {
            $instance = juser::getinstance($id);
         }
         else
         {
            $instance = self::getsession()->get('user');
         }
      }
      return $instance;
   }

per operators comparison docs on php.net,

if compare number string or comparison involves numerical strings, each string converted number , comparison performed numerically.

an example indicates

var_dump(0 == "a"); // 0 == 0 -> true

(0 != "a") should evaluate false.

the code

code: select all

if ($current->id != $id)

comparing (0 != 'angrybird") , evaluate false. believe true evaluation required continue

code: select all

$instance = juser::getinstance($id);

'username' converted user's 'id' via user.php (getinstance()) , helper.php (getuserid()).

am interpreting correctly or missing something?

check out juser class, __construct method.

http://joomlacode.org/gf/project/joomla/scmsvn/?action=browse&path=/development/tags/1.6.x/1.6.3/libraries/joomla/user/user.php&view=markup

the accepted parameter $identifier used load user data object, or if default value of 0 create blank user object. since jfactory merely pattern allowing static calls needed functionality, has same limitations underlying juser class. can check out doc on jfactory v1.6 class here.

http://docs.joomla.org/jfactory/1.6

if you, write dedicated static mehtod in component or module helper class handle logic of taking user name , returning user id. make alter code below, assuming extension component:

code: select all

jloader::register('myextensionhelper', jpath_component.'/helpers/myextension.php');
$getuser = jfactory::getuser(myextensionhelper::getuseridfromname($name));
