Question

在早期版本2.2.6中，我使用以下代码：

$this->db->_protect_identifiers=false;

$dataField='tm.*,IFNULL(CONCAT_WS(" " ,pm.firstName,pm.lastName),"") as assignedToName,IFNULL(cm.caseNo,"") as CaseNo,IFNULL(cm1.fileNo,"") as fileNo,IFNULL(sm.caseStage,"") as caseStage';

$qryTable='task_mst as tm 
            LEFT JOIN case_mst as cm on tm.caseNo=cm.ID
            LEFT JOIN case_mst as cm1 on tm.fileNo=cm1.ID
            LEFT JOIN party_mst as pm on tm.assignedTo=pm.ID
            LEFT JOIN session_mst as sm on tm.sessionId=sm.ID';
$task= $this->db->select($dataField,false)->from($qryTable)->where($where,NULL,FALSE)->order_by("ID","desc")->limit(10)->get()->result_array();

现在我使用的是版本3.1.0但是＆＃34; _protect_identifiers＆＃34;会给出错误信息

Fatal error: Cannot access protected property CI_DB_mysqli_driver::$_protect_identifiers

任何人都可以告诉我如何使用＆＃34; protect_identifiers（）＆＃34;在codeigniter 3.1.0？

Answer 2

尝试这样设置..

$this->db->protect_idenifiers(FALSE)->select(...)->where(...)

有关详情，请参阅this。

Answer 3

只需从$ this-＆gt; db-＆gt; _protect_identifiers中删除_。（下划线符号）

$this->db->protect_identifiers=false;

这是新版本中的CI更改。

codeigniter 3.1.0
