Question

这是我得到的控制台错误 mysql_real_escape_string（）：不推荐使用mysql扩展，将在中删除未来：使用mysqli或PDO代替。我在Datatable库文件中遇到这个错误。有人知道是什么问题吗？

我的观点

public function manageuser()
        { 
             $tmpl = array ( 'table_open'  => '<table id="big_table" border="1" cellpadding="2" cellspacing="1" class="mytable">' );
            $this->table->set_template($tmpl); 

            $this->table->set_heading('First Name','Last Name','Email');

             $this->load->view('moderator/manageuser');
        }
         public function datatable()
        {

             $this->datatables
            ->select("mro_id,mro_name,mctg_name,mctg_id")
            ->from('jil_mroproducts')
            ->join('jil_mrocategory', 'jil_mroproducts.mro_category=jil_mrocategory.mctg_id', 'INNER')
           ->edit_column('mro_name', '<a href="User/edit/$1">$2</a>', 'mro_id, mro_name');
            //->unset_column('mro_id');
             echo $this->datatables->generate();      
        }

我将此代码用于数据表。

代码在库中使用 mysql_real_escape_string（），因此不推荐使用。

您必须从代码中删除 mysql_real_escape_string（）并使用自定义代码。
否则你必须使用mysqli驱动程序进行codeigniter。然后你可以使用mysqli_real_escape_string（）。

CodeIgniter switching driver from mysql --> mysqli

更新：在下面添加天使解决方案。

$sSearch =$this->ci->db->escape_like_str($this->ci->input->post('sSearch'));

获取控制台错误：mysql_real_escape_string（）在使用时被点燃数据表codeigniter
