在我的分页代码中,从表中获取数据表明其数据搜索和分页有效,但记录却多次显示
在上图中,您可以看到记录的修复。
控制器:
public function getData(){
$postData = $this->input->post();
$data = $this->dispatchModel->viewData($postData);
echo json_encode($data);
}
型号:
function viewData($postData=null){
$response = array();
## Read value
$draw = $postData['draw'];
$start = $postData['start'];
$rowperpage = $postData['length']; // Rows display per page
$columnIndex = $postData['order'][0]['column']; // Column index
$columnName = $postData['columns'][$columnIndex]['data']; // Column name
$columnSortOrder = $postData['order'][0]['dir']; // asc or desc
$searchValue = $postData['search']['value']; // Search value
## Search
$searchQuery = "";
if($searchValue != ''){
$searchQuery = " (b.disp_ch_driver like'%".$searchValue."%') ";
}
## Total number of records without filtering
$this->db->select('count(*) as allcount');
$records = $this->db->get('dispatch_challan')->result();
$totalRecords = $records[0]->allcount;
## Total number of record with filtering
$this->db->select('count(*) as allcount');
if($searchValue != '')
$this->db->where($searchQuery);
$records = $this->db->get('dispatch_challan b')->result();
$totalRecordwithFilter = $records[0]->allcount;
## Fetch records
$this->db->select('vn.vehicle_no as vehicle,bn.branch_name as from_branch_name,bn1.branch_name as to_branch_name,b.*,vn.*,bn.*,bn1.*');
$this->db->from('dispatch_challan b');
$this->db->join('vehicle vn', 'b.disp_ch_lorryno=vn.vehicle_id','left');
$this->db->join('branch bn', 'b.disp_ch_from=bn.branch_id','left');
$this->db->join('branch bn1','b.disp_ch_to=bn1.branch_id','left');
$this->db->where('b.status','active');
if($searchValue != '')
$this->db->where($searchQuery);
$this->db->order_by($columnName, $columnSortOrder);
$this->db->limit($rowperpage, $start);
$records = $this->db->get('dispatch_challan')->result();
$data = array();
foreach($records as $record ){
$data[] = array(
"disp_ch_no" =>$record->disp_ch_no,
"disp_ch_date" =>$record->disp_ch_date,
"from_branch_name" =>$record->from_branch_name,
"to_branch_name" =>$record->to_branch_name,
"vehicle" =>$record->vehicle,
"disp_ch_pan" =>$record->disp_ch_pan,
"disp_ch_driver" =>$record->disp_ch_driver,
"disp_ch_owner" =>$record->disp_ch_owner,
"disp_ch_remark" =>$record->disp_ch_remark
);
}
## Response
$response = array(
"draw" => intval($draw),
"iTotalRecords" => $totalRecordwithFilter,
"iTotalDisplayRecords" => $totalRecords,
"aaData" => $data
);
return $response;
}
在上述模型中,有分页代码,但记录多次显示。 在我的数据库中,我只有5条记录。

问题可能不是表分页中的数据库查询。尝试使用邮递员运行模型或api,并观察重复或不重复的结果。
