I’m working an application based on CodeIgniter. Here the code:
Controller:
public function index(){
$data = array(
'record' => $this->Parameter_model->get_parameter('tbl_parameter')
);
$this->site->view('parameter', $data);
}
Model:
public function get_parameter($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 $data;
}
View:
<table id="parameter" class="listdata table table-bordered table-striped table-hover">
<thead>
<tr>
<th class="text-nowrap">Parameter</th>
<th class="text-nowrap">Method</th>
<th class="text-nowrap">Type</th>
<th class="text-nowrap">Action</th>
</tr>
</thead>
<tbody>
<?php if(!empty($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;
$( 'input', this.footer() ).on( 'keyup change', function () {
if ( that.search() !== this.value ) {
that
.search( this.value )
.draw();
}
} );
} );
Above code work well.
Now, I want to fetch data into the table id="parameter" via ajax request. I’ve create an ajax request from url, lets say from here http://'+host+path+'/action/ambil, where var path = window.location.pathname; and var host = window.location.hostname;.
The ajax response produce:
{"record":[{"parameter_ID":"1","parameter_name":"pH","parameter_method":"(pH meter)","parameter_type":"1",{"parameter_ID":"2","parameter_name":"Viscosity","parameter_method":"(Brookfield-Viscometer)","parameter_type":"1"}]}
Question
How to configure datatable with Ajax data source, and how to display the data into the table, so I can use the data for example to create a link like code
<a href="<?=set_url('parameter/parameter_view/'.$row['parameter_ID']);?>">

Answer
You can do dataTable by server side script as follow.
- Change your controller so that It will handle the server side call from datatable and you can create dynamic links in controller only. I have added comment in controller for more details.
- Change your script to call it with ajax.
- Don’t load any thing in view tbody while loading page.
- Note : I have skipped the model part I used direct query. Hope you can change it.

If you wish to use some third party library check this. For your model query you can customize it as mention in this post.
