[英]Codeigniter - How to fetch datatable data from ajax?
我正在基於CodeIgniter的應用程序。 這里的代碼:
控制器 :
public function index(){
$data = array(
'record' => $this->Parameter_model->get_parameter('tbl_parameter')
);
$this->site->view('parameter', $data);
}
型號 :
public function get_parameter($table){
$query = $this->db->query("select * from $table order by 'parameter_ID' ASC");
if($query->num_rows() > 0){
foreach($query->result_array() as $row){
$data[] = $row;
}
$query->free_result();
}
else{
$data = NULL;
}
return $data;
}
查看 :
<table id="parameter" class="listdata table table-bordered table-striped table-hover">
<thead>
<tr>
<th class="text-nowrap">Parameter</th>
<th class="text-nowrap">Method</th>
<th class="text-nowrap">Type</th>
<th class="text-nowrap">Action</th>
</tr>
</thead>
<tbody>
<?php if(!empty($record)):?>
<?php foreach($record as $row):?>
<tr align="center">
<td class="text-nowrap"><a href="<?=set_url('parameter/parameter_view/'.$row['parameter_ID']);?>"><strong><?php echo $row['parameter_name'];?></strong></a></td>
<td class="text-nowrap"><?php echo $row['parameter_method'];?></td>
<td class="text-nowrap">
<?php
if($row['parameter_type'] == "1"){
echo "General";
}
else{
echo "COA Only";
}
?>
</td>
<td class="text-nowrap">
<div>
<a href="<?=set_url('parameter#edit?parameter_ID='.$row['parameter_ID']);?>" class="btn btn-warning btn-xs">Edit</a>
<a href="<?=set_url('parameter/parameter_view/'.$row['parameter_ID']);?>" class="btn btn-success btn-xs">Lihat</a>
<a href="<?=set_url('parameter#hapus?parameter_ID='.$row['parameter_ID']);?>" class="btn btn-danger btn-xs">Hapus</a>
</div>
</td>
</tr>
<?php endforeach;?>
<?php endif;?>
</tbody>
<tfoot>
<tr>
<th class="text-nowrap">Parameter</th>
<th class="text-nowrap">Method</th>
<th class="text-nowrap">Type</th>
<th class="text-nowrap">Action</th>
</tr>
</tfoot>
</table>
Javascript :
// parameter
// Setup - add a text input to each footer cell
$('#parameter tfoot th').each( function () {
var title = $(this).text();
$(this).html( '<input type="text" style="width:100%;" title="Search '+title+'" placeholder="Search '+title+'" />' );
} );
// DataTable
var table = $('#parameter').DataTable({
paging: true,
searching: true,
ordering: true,
"order": [[ 0, "asc" ]],
scrollX: true,
scroller: true,
});
// Apply the search
table.columns().every( function () {
var that = this;
$( 'input', this.footer() ).on( 'keyup change', function () {
if ( that.search() !== this.value ) {
that
.search( this.value )
.draw();
}
} );
} );
上面的代碼運行良好。
現在,我想通過ajax請求將數據提取到table id="parameter"
。 我已經從url創建了一個ajax請求,可以從這里http://'+host+path+'/action/ambil
,其中var path = window.location.pathname;
和var host = window.location.hostname;
。
Ajax響應產生:
{"record":[{"parameter_ID":"1","parameter_name":"pH","parameter_method":"(pH meter)","parameter_type":"1",{"parameter_ID":"2","parameter_name":"Viscosity","parameter_method":"(Brookfield-Viscometer)","parameter_type":"1"}]}
題
如何使用Ajax數據源配置數據表,以及如何將數據顯示到表中,因此我可以使用數據例如創建類似代碼的鏈接
<a href="<?=set_url('parameter/parameter_view/'.$row['parameter_ID']);?>">
您可以按以下方式通過服務器端腳本執行dataTable。
控制器
public function index() {
$data = array();
if ($this->input->is_ajax_request()) {
/** this will handle datatable js ajax call * */
/** get all datatable parameters * */
$search = $this->input->get('search');/** search value for datatable * */
$offset = $this->input->get('start');/** offset value * */
$limit = $this->input->get('length');/** limits for datatable (show entries) * */
$order = $this->input->get('order');/** order by (column sorted ) * */
$column = array('parameter', 'method', 'type');/** set your data base column name here for sorting* */
$orderColumn = isset($order[0]['column']) ? $column[$order[0]['column']] : 'parameter';
$orderDirection = isset($order[0]['dir']) ? $order[0]['dir'] : 'asc';
$ordrBy = $orderColumn . " " . $orderDirection;
if (isset($search['value']) && !empty($search['value'])) {
/** creat sql or call Model * */
/** $this->load->model('Parameter_model');
$this->Parameter_model->get_parameter('tbl_parameter'); * */
/** I am calling sql directly in controller for your answer
* Please change your sql according to your table name
* */
$sql = "SELECT * FROM TABLE_NAME WHERE column_name '%like%'" . $search['value'] . " order by " . $ordrBy . " limit $offset,$limit";
$sql = "SELECT count(*) FROM TABLE_NAME WHERE column_name '%like%'" . $search['value'] . " order by " . $ordrBy;
$result = $this->db->query($sql);
$result2 = $this->db->query($sql2);
$count = $result2->num_rows();
} else {
/**
* If no seach value avaible in datatable
*/
$sql = "SELECT * FROM TABLE_NAME order by " . $ordrBy . " limit $offset,$limit";
$sql2 = "SELECT * FROM TABLE_NAME order by " . $ordrBy;
$result = $this->db->query($sql);
$result2 = $this->db->query($sql2);
$count = $result2->num_rows();
}
/** create data to display in dataTable as you want **/
$data = array();
if (!empty($result->result())) {
foreach ($result->result() as $k => $v) {
$data[] = array(
/** you can add what ever anchor link or dynamic data here **/
'parameter' => "<a href=".set_url('parameter/parameter_view/'.$v['parameter_ID'])."><strong>".$v['parameter_name']."</strong></a>",
'method' => "<a href=".set_url('parameter/parameter_view/'.$v['parameter_ID'])."><strong>".$v['parameter_name']."</strong></a>",
'parameter_type' => "<a href=".set_url('parameter/parameter_view/'.$v['parameter_ID'])."><strong>".$v['parameter_name']."</strong></a>",
'actions' => "<a href=".set_url('parameter/parameter_view/'.$v['parameter_ID'])."><strong>".$v['parameter_name']."</strong></a>"
);
}
}
/**
* draw,recordTotal,recordsFiltered is required for pagination and info.
*/
$results = array(
"draw" => $this->input->get('draw'),
"recordsTotal" => count($data),
"recordsFiltered" => $count,
"data" => $data
);
echo json_encode($results);
} else {
/** this will load by default with no data for datatable
* we will load data in table through datatable ajax call
*/
$this->site->view('parameter', $data);
}
}

您可以查看這篇文章 。 盡管我使用原始php編寫了它,但是您可以通過使用該ssp類創建一個單獨的庫來輕松實現它,並且可以創建這種類型的鏈接。
您可以嘗試我的代碼,這對我來說很好。
控制器代碼
public function showFeeCode()
{
$data = $this->fmodel->fetchAllData('*','fee_assign',array());
if (is_array($data) || is_object($data))
{
foreach ($data as $key => $value) {
$button = "";
$button .= "<button class='btn btn-success fa fa-pencil' onclick='editFunction(".$value['id'].")' data-toggle='tooltip' title='Edit Details'></button> ";
$result['data'][$key] = array(
$value['feegroup'],
$value['name'],
$button
);
}
}
echo json_encode($result);
}
模態代碼
public function fetchAllData($data,$tablename,$where)
{
$query = $this -> db
->where($where)
-> get($tablename);
if($query->num_rows() > 0){
return $query->result_array();
}
else{
return array('error');
}
}
查看代碼(表)
<table id="myTable" class="table display">
<thead class="alert alert-danger">
<tr>
<th>Fee Type</th>
<th>Fee Code</th>
<th>Action</th>
</tr>
</thead>
</table>
ajax代碼以獲取ajax代碼在視圖頁面中接收的數據。
$(document).ready(function() {
$('#myTable').dataTable( {
"ajax":"<?= base_url('Fee/showFeeCode'); ?>",
'order':[],
});
});
如果要將參數傳遞給控制器,則可以通過ajax傳遞給控制器
$(document).ready(function() {
var id = 4;
$('#myTable').dataTable( {
"ajax":"<?= base_url('Fee/showFeeCode'); ?>/"+id,
'order':[],
});
});
您可以在將參數傳遞到控制器功能的幫助下接收此ID。
如果要發送多個數據,則可以使用此格式
var first_data = 1;
var second_data = 2;
$('#myTable').dataTable( {
"ajax": {
"url": '<?php echo base_url('fetchData') ?>',
"type": "POST",
"data": {first_data:first_data,second_data:second_data}
},
'order':[],
});
});
