joomla2.5 - 我收到 SQL 语法错误

Question

我使用 joomla 2.5.27 和 community builder 2.0.2。我为社区构建器使用 cb rank 插件我收到错误

您的 SQL 语法有错误；检查与您的 MySQL 服务器版本相对应的手册，以在第 1 行的“AND confirmed= 1 AND approved= 1”附近使用正确的语法 SQL=SELECT COUNT( id) FROM r2yze_comprofiler WHERE cb_points> AND confirmed = 1 AND approved= 1

如何修复此错误

PHP 代码

// 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;

尝试这个。

// 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;
