joomla database select and insert query - mysql

Question

i am trying to insert another info to joomla (2.5.7) database after user is registered. The user chooses his usergroup and I want the insertion to happen only when the user is in a specific group. So I am trying to use this code to get the group data from the databse first to be used in the insert query. Now it is just a testing ground, later this retrieved value be used in if statement.
This is the code:
function onUserAfterSave($user, $isnew, $success, $msg)
{
if ($isnew && $success) {
$db = &JFactory::getDBO();
$query = "SELECT #__k2_users.group FROM #__k2_users WHERE userID = ".$user['id'];
$db->setQuery($query);
$group = $db->loadResult();
$db->setQuery( 'INSERT INTO #__user_profiles (ordering) VALUES ('.$group.')' );
$db->query();
if (!$db->query())
{
throw new Exception($db->getErrorMsg());
}
}
return $this->onAfterStoreUser($user, $isnew, $success, $msg);
}
and this is the error I am getting upon the failed registration:
Column count doesn't match value count at row 1 SQL=INSERT INTO std13_user_profiles (ordering) VALUES ()
If I read it correctly, it means that the select statement is not returning anything but why? Thank you for your help.
UPDATE:
if ($isnew && $success) {
$db = &JFactory::getDBO();
$userId = JArrayHelper::getValue($user, 'id', 0, 'int');
$query = "SELECT #__k2_users.group FROM #__k2_users WHERE userID = ".$userId;
$db->setQuery($query);
$group = $db->loadResult();
$query2 = "INSERT INTO #__user_profiles (ordering) VALUES ('".$group."')";
$db->setQuery($query2);
$db->query();
if (!$db->query())
{
throw new Exception($db->getErrorMsg());
}
}
with this code, I don't get any errors and the user is registered and the values are inserted. However the $group is always 0 and based on the value is only 1 or 3 in k2_users table, I am guessing that it returns nothing. I think it may be because the registered user is not stored in the databse yet and it doesn't have his ID yet to look for the group?
UPDATE2:
if ($isnew && $success) {
$count = JRequest::getVar('gender');
if($count == 3) {
$db = &JFactory::getDBO();
$alias = $user['name'];
$table = array(
' '=>'-', 'Š'=>'S', 'š'=>'s', 'Ð'=>'Dj', 'Ž'=>'Z', 'ž'=>'z', 'C'=>'C', 'c'=>'c', 'C'=>'C', 'c'=>'c',
'À'=>'A', 'Á'=>'A', 'Â'=>'A', 'Ã'=>'A', 'Ä'=>'A', 'Å'=>'A', 'Æ'=>'A', 'Ç'=>'C', 'È'=>'E', 'É'=>'E',
'Ê'=>'E', 'Ë'=>'E', 'Ì'=>'I', 'Í'=>'I', 'Î'=>'I', 'Ï'=>'I', 'Ñ'=>'N', 'Ò'=>'O', 'Ó'=>'O', 'Ô'=>'O',
'Õ'=>'O', 'Ö'=>'O', 'ě'=>'e', 'Ù'=>'U', 'Ú'=>'U', 'Û'=>'U', 'Ü'=>'U', 'Ý'=>'Y', 'Þ'=>'B', 'ß'=>'Ss',
'à'=>'a', 'á'=>'a', 'â'=>'a', 'ã'=>'a', 'ä'=>'a', 'å'=>'a', 'æ'=>'a', 'ç'=>'c', 'è'=>'e', 'é'=>'e',
'ê'=>'e', 'ë'=>'e', 'ì'=>'i', 'í'=>'i', 'î'=>'i', 'ï'=>'i', 'ð'=>'o', 'ñ'=>'n', 'ò'=>'o', 'ó'=>'o',
'ô'=>'o', 'õ'=>'o', 'ö'=>'o', 'ø'=>'o', 'ù'=>'u', 'ú'=>'u', 'û'=>'u', 'ý'=>'y', 'ý'=>'y', 'þ'=>'b',
'ÿ'=>'y', 'R'=>'R', 'r'=>'r', " "=>'-', '"'=>'-'
);
$string = strtr($alias, $table);
$alias_low = strtolower($string);
$query = "INSERT INTO #__menu (menutype, title, alias, path, link, type, published, level, component_id, access) VALUES ('stavebnici','".$user['name']."','".$alias_low."','".$alias_low."',
'index.php?option=com_k2&view=itemlist&layout=user&id=".$user['id']."&task=user','component',1,1,10012,1)";
$db->setQuery($query);
$db->query();
if (!$db->query())
{
throw new Exception($db->getErrorMsg());
}
}
}
OKAY! I got it working so now I can insert new menu every time a user is created, however th activation link is not created and the registration says that it failed. This is the error:
Duplicate entry '0-1-vojtech-plesner-' for key 'idx_client_id_parent_id_alias_language' SQL=INSERT INTO std13_menu (menutype, title, alias, path, link, type, published, level, component_id, access) VALUES ('stavebnici','Vojtěch Plešner','vojtech-plesner','vojtech-plesner', 'index.php?option=com_k2&view=itemlist&layout=user&id=2789&task=user','component',1,1,10012,1)
The client_id, parent_id and language have values of 1,1 and * abd they are in all the rows so why is it saying it is duplicate?

Answer 1

You need to update that query to 2.5 style.
http://www.theartofjoomla.com/home/9-developer/135-database-upgrades-in-joomla-16.html
is a good article.
You definitely seem to be missing
$query = $db->getQuery(true);
not to mention that you are using & for an object. That usage will generate strict errors.

Answer 2

You can do it with one query:
$query = "
INSERT INTO #__user_profiles (ordering)
SELECT #__k2_users.group
FROM #__k2_users
WHERE userID = " . user['id']
";
But doesn't #__user_profiles have other columns like the user id?

Answer 3

Also You can do it with one query:
$query = "
INSERT INTO #__user_profiles (ordering)
SELECT "YOURJOOMLADBPREFIX"_k2_users.group
FROM "YOURJOOMLADBPREFIX"_k2_users
WHERE userID = " . user['id']
";
