您的SQL語法錯誤;檢查 對應於你的MySQL服務器版本正確的語法使用 附近 'AND confirmed = 1 AND approved = 1' 第1行SQL =選擇 COUNT（id）FROM r2yze_comprofiler WHERE cb_points手冊> AND confirmed = 1和approved = 1

如何修復這個錯誤

PHP代碼

// Calculate rank 
    if ($ordertype == "low") { 
     $_CB_database->setQuery("SELECT COUNT(`id`) FROM #__comprofiler WHERE `$fieldname` < $userfield AND `confirmed` = 1 AND `approved` = 1"); 
    } 
    else { 
     $_CB_database->setQuery("SELECT COUNT(`id`) FROM #__comprofiler WHERE `$fieldname` > $userfield AND `confirmed` = 1 AND `approved` = 1"); 
    } 
    $value = $_CB_database->loadResult() + 1;

試試這個。

// Calculate rank 
     if ($ordertype == "low") { 
      $_CB_database->setQuery("SELECT COUNT(`id`) FROM #__comprofiler WHERE ".$fieldname." < '".$userfield."' AND `confirmed` = 1 AND `approved` = 1"); 
     } 
     else { 
      $_CB_database->setQuery("SELECT COUNT(`id`) FROM #__comprofiler WHERE ".$fieldname." > '".$userfield."' AND `confirmed` = 1 AND `approved` = 1"); 
     } 
     $value = $_CB_database->loadResult() + 1;
