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;
}

} );
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-Viseter)","parameter_type":"1"}]}

Reset to default 3You 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 ment 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.
Updated with More explanation and more code
You can try my code this is working fine for me.
Controller Code
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);
}
Modal Code
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');
}
}
view code (table)
<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 code to fetch the data the ajax code recides in the view page.
$(document).ready(function() {
$('#myTable').dataTable( {
"ajax":"<?= base_url('Fee/showFeeCode'); ?>",
'order':[],
});
});
if you want to pass some parameter to the controller then you can pass it by ajax
$(document).ready(function() {
var id = 4;
$('#myTable').dataTable( {
"ajax":"<?= base_url('Fee/showFeeCode'); ?>/"+id,
'order':[],
});
});
You can receive this id with the help of passing parameter to the controller function.
if you want to send multiple data then you can use this format
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':[],
});
});
