Question

I am not confirmed with this query… I feel like somewhere the CU or CI has been misplaced…
This query worked properly without using $db->nameQuote in sql.

 $query = 'SELECT '. $db->nameQuote(CU.'id')
        .' FROM '. $db->nameQuote('#__users'), $db->nameQuote('#__community_cinvit' CI)
        .' WHERE '. $db->nameQuote(CU.'email').'='.$db->Quote(CI.'to_email')
        .'AND'. $db->nameQuote(CI.'point_given').'='.$db->Quote('1');

        $db->setQuery($query);
        $conn = $db->loadResult();
        echo $conn;

is there any error in CU and CI

Answer 1

add white space before .' AND'. and add CU to $db->nameQuote('#__users' CU)

 $query = 'SELECT '. $db->nameQuote(CU.'id')
        .' FROM '. $db->nameQuote('#__users' CU), $db->nameQuote('#__community_cinvit' CI)
        .' WHERE '. $db->nameQuote(CU.'email').'='.$db->Quote(CI.'to_email')
        .' AND'. $db->nameQuote(CI.'point_given').'='.$db->Quote('1');

        $db->setQuery($query);
        $conn = $db->loadResult();
        echo $conn;
