DataTable using PHP

Question

Is it possible to code a DataTable using PHP?

When searching online all tutorials etc are using ajax, which I\'m not to comfortable with so just wondering if there

Answer 1

1)Include Css and JS files:

2)Create function in controller file:

function MyData()
        {
            $aColumns = array('user_id','username','address');

            $sTable = 'user';

            $iDisplayStart = $this->input->get_post('iDisplayStart', true);
            $iDisplayLength = $this->input->get_post('iDisplayLength', true);
            $iSortCol_0 = $this->input->get_post('iSortCol_0', true);
            $iSortingCols = $this->input->get_post('iSortingCols', true);
            $sSearch = $this->input->get_post('sSearch', true);
            $sEcho = $this->input->get_post('sEcho', true);

            // Paging
            if(isset($iDisplayStart) && $iDisplayLength != '-1')
            {
                $this->db->limit($this->db->escape_str($iDisplayLength), $this->db->escape_str($iDisplayStart));
            }

            // Ordering
            if(isset($iSortCol_0))
            {
                for($i=0; $iinput->get_post('iSortCol_'.$i, true);
                    $bSortable = $this->input->get_post('bSortable_'.intval($iSortCol), true);
                    $sSortDir = $this->input->get_post('sSortDir_'.$i, true);

                    if($bSortable == 'true')
                    {
                        $this->db->order_by($aColumns[intval($this->db->escape_str($iSortCol))], $this->db->escape_str($sSortDir));
                    }
                }
            }

            /* 
             * Filtering
             * NOTE this does not match the built-in DataTables filtering which does it
             * word by word on any field. It's possible to do here, but concerned about efficiency
             * on very large tables, and MySQL's regex functionality is very limited
             */
            if(isset($sSearch) && !empty($sSearch))
            {
                for($i=0; $iinput->get_post('bSearchable_'.$i, true);

                    // Individual column filtering
                    if(isset($bSearchable) && $bSearchable == 'true')
                    {
                        $this->db->or_like($aColumns[$i], $this->db->escape_like_str($sSearch));
                    }
                }
            }

            // Select Data


            $this->db->select('SQL_CALC_FOUND_ROWS '.str_replace(' , ', ' ', implode(', ', $aColumns)), false);               
            $rResult = $this->db->get($sTable);

            // Data set length after filtering
            $this->db->select('FOUND_ROWS() AS found_rows');
            $iFilteredTotal = $this->db->get()->row()->found_rows;

            // Total data set length
            $iTotal = $this->db->count_all($sTable);

            // Output
            $output = array(
                'sEcho' => intval($sEcho),
                'iTotalRecords' => $iTotal,
                'iTotalDisplayRecords' => $iFilteredTotal,
                'aaData' => array()
            );

            foreach($rResult->result_array() as $aRow)
            {
                $row = array();

                foreach($aColumns as $col)
                {
                     $row[] = $aRow['user_id'];
                     $row[] = $aRow['username'];
                     $row[] = $aRow['address'];
                }

                $output['aaData'][] = $row;
            }

            echo json_encode($output);

        }

3)Create a table in view file:

                    

                      

                           
User Id
                           
Username
                           
Address
                           
Edit / Delete
                      
                    
        
               

4)Write AJAX:
