php - joomla 3x insert a string into sql database -


i'm running joomla 3x portal , need insert string mysql database, have had no success far (sadly, i'm not programmer).

so added new field users table called "ok1" , want insert string (actually hyperlink) , overwrite every time current 1 on page executed code last.

this code used, "blows" portal...

$query = $db->getquery(true);  $columns = "ok1";  $values = "my hyperlink";  $query     ->insert($db->quotename('#__users'))     ->columns($db->quotename($columns))     ->values($db->quotename($values));  $db->setquery($query); $db->execute();  $query = $db->getquery(true);  $db->setquery($query); $db->execute();

hopefully can me out one, in advance.

second attempt:

$content ="test" $query = $db->getquery(true); update `x__users` set `ok1`=$content `user` = $user->id; $db->setquery($query); $result = $db->execute();

what want this

$columns = "ok1";  $values = "my hyperlink";  $query     ->update($db->quotename('#__users'))      ->set($db->quotename($columns) = $db->quote($values))     ->where($db-quotename('user') = $user->id) ;  $db->setquery($query); $db->execute();

that want update record not insert new one, , want specific record indicated clause. use correct quote values (since not names).
