如何在phprunner where子句中传递获取值？

Question

我在获取方法方面很有价值，但我不知道如何将该值传递给phprunner中的条件

$auction= $_GET['auction_no'];
var $_SqlWhere = "";
function getSqlWhere($auction) { // Where
    $sWhere = ($this->_SqlWhere <> "") ? $this->_SqlWhere : "";
    $this->TableFilter = "`auction_no`='".$auction."'";
    ew_AddFilter($sWhere, $this->TableFilter);
    return $sWhere;
}

唯一的空值正在传递
