当前，我正在电子商务网站上工作，因为我必须显示从数据库到数据表的所有数据。数据在数据表中正确输入，但是搜索，排序和分页不起作用。如果有人知道解决方案，请帮助。下面是我的代码 Controller.php
Public function transaction_data()
{
$id = $this->session->Vendordetail['id'];
$transactionData = $this->Mdl_vendor_payment->get_order_list($id);
$requestData= $_REQUEST;
$totalData = count($transactionData);
$totalFiltered = count($transactionData);
$return_days = $this->Mdl_common->get_setting('shipping_charge');
foreach($transactionData as $transaction){
$product = $this->Mdl_common->product_id($transaction['prodouct_id']);
$data['order_id'] = $transaction['order_id'];
$data['created'] = $transaction['created'];
if($transaction['status'] == 5){
$data['status'] = '<h5><span class="label label-danger">Cancelled</span></h5>';
}else if($transaction['status'] == 4){
$data['status'] = '<h5><span class="label label-default">Return</span></h5>';
}else if($transaction['status'] == 3){
$data['status'] = '<h5><span class="label label-success">Success</span></h5>';
}else if($transaction['status'] == 2){
$data['status'] = '<h5><span class="label label-primary">Dispatch</span></h5>';
}else if($transaction['status'] == 1){
$data['status'] = '<h5><span class="label label-primary">Ready To Dispatch</span></h5>';
}else{
$data['status'] = '<h5><span class="label label-primary">Approve</span></h5>';
}
$data['price'] = '<i class="fa fa-rupee"></i> '.$transaction['price']*$transaction['qty'];
$data['settlement_price'] = '<i class="fa fa-rupee"></i> '.$transaction['settlement_price']*$transaction['qty'];
$shipping_charge = $return_days['value'] * ($transaction['qty'] * $product['weight']);
$data['shipping_charge'] = '<i class="fa fa-rupee"></i> '.$shipping_charge;
$data['commission_fee'] = ($transaction['price']*$transaction['qty'])-($transaction['settlement_price']-$transaction['qty']);
$data['payable_amount'] = ($transaction['settlement_price']*$transaction['qty'])-$shipping_charge;
$data['order'] = $transaction;
$data['product'] = $product;
$assignment_datas[] = $data;
}
$json_data = array(
"draw" => intval( $requestData['draw'] ),
"recordsTotal" => intval( $totalData ),
"recordsFiltered" => intval( $totalFiltered ),
"data" => $assignment_datas
);
echo json_encode($json_data);
die;
}
下面是查看文件的代码 View.php
$(document).ready(function() {
var dt = $('#datatable_example').DataTable( {
"processing": true,
"serverSide": true,
"ajax": {
"url":"<?php echo base_url(); ?>index.php/Vendor_payment/transaction_data",
"type":"POST",
},
"columns": [
{
"class": "details-control",
"orderable": false,
"data": null,
"defaultContent": ""
},
{ "data": "order_id" },
{ "data": "created" },
{ "data": "status" },
{ "data": "price" },
{ "data": "settlement_price" },
{ "data": "shipping_charge" }
],
"order": [[0, 'asc']]
} );
// Array to track the ids of the details displayed rows
var detailRows = [];
$('#datatable_example tbody').on( 'click', 'tr td.details-control', function () {
var tr = $(this).closest('tr');
var row = dt.row( tr );
var idx = $.inArray( tr.attr('id'), detailRows );
if ( row.child.isShown() ) {
tr.removeClass( 'details' );
row.child.hide();
// Remove from the 'open' array
detailRows.splice( idx, 1 );
}
else {
tr.addClass( 'details' );
row.child( format( row.data() ) ).show();
// Add to the 'open' array
if ( idx === -1 ) {
detailRows.push( tr.attr('id') );
}
}
} );
// On each draw, loop over the `detailRows` array and show any child rows
dt.on( 'draw', function () {
$.each( detailRows, function ( i, id ) {
$('#'+id+' td.details-control').trigger( 'click' );
} );
} );
} );
答案 0 :(得分：0)
此代码对我来说很好...
在查看页面：
<table id="user_datatable" class="table table-bordered table-striped">
<thead>
<tr>
<th style="width: 5%;">ID</th>
<th>Client name</th>
<th>Mobile</th>
<th>Email</th>
<th class="col-md-2">Action</th>
</tr>
</thead>
<tbody></tbody>
</table>
<script type="text/javascript">
$(document).ready(function () {
$('#user_datatable').DataTable({
'pageLength': 1,
'processing': true,
'serverSide': true,
'serverMethod': 'post',
'ajax': {
'url': '<?php echo base_url(); ?>user/userList'
},
'columns': [{
data: 'id'
},
{
data: 'name'
},
{
data: 'mobile'
},
{
data: 'email'
},
{
data: 'action'

]
});
});
</script>
在“控制器”页面
public function userList() {
$postData = $this->input->post();
$data = $this->Data_model->getUserList($postData);
echo json_encode($data);
}
在“模型”页面
Set the table name in $table variable
// $table = 'clients';
Add column name whatever you add in datatable
$searchQuery = " (name like '%".$searchValue."%' or mobile like '%".$searchValue."%' or email like'%".$searchValue."%' ) ";
function getUserList($postData=null) {
$response = array();
$table_name = 'clients';
## 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 != ''){
$searchQuery = " (name like '%".$searchValue."%' or mobile like '%".$searchValue."%' or email like'%".$searchValue."%' ) ";
}
## Total number of records without filtering
$this->db->select('count(*) as allcount');
$records = $this->db->get($table_name)->row();
$totalRecords = $records->allcount;
## Total number of record with filtering
$this->db->select('count(*) as allcount');
if($searchValue != '')
$this->db->where($searchQuery);
$records = $this->db->get($table_name)->row();
$totalRecordwithFilter = $records->allcount;
## Fetch records
$this->db->select('*');
if($searchValue != '')
$this->db->where($searchQuery);
$this->db->order_by($columnName, $columnSortOrder);
$this->db->limit($rowperpage, $start);
$records = $this->db->get($table_name)->result();
$data = array();
foreach($records as $key => $record) {
$data[] = array(
"id"=> ($key + 1),
"name"=>$record->name,
"mobile"=>$record->mobile,
"email"=>$record->email,
"action"=>"<a href='".base_url()."user/update/".$record->id."' type='button' class='btn btn-success'>Update</a><a href='".base_url()."user/delete/".$record->id."' type='button' class='btn btn-danger' style='margin-left: 5px;'>Delete</a>",
);
}
## Response
$response = array(
"draw" => intval($draw),
"recordsTotal" => $totalRecordwithFilter,
