Ignited Datatables - display records on screen - php

Question

I'm using Ignited Datatables to display posts in tabular way in my view. I've been struggling the last 4 days in order to do this working correct, but I can't understand what I'm doing wrong.
This is the functionality that fetches the data
// the Post_model
/**
* Get page data on datatables
*/
public function get_datatable() {
$this->load->library('datatables');
$this->datatables->select('id, title, slug, sort_description, status');
$this->datatables->from('posts');
return $this->datatables->generate();
}
// the posts controller
/**
* List all posts
*/
public function index() {
$this->data['datatables'] = true;
$this->data['data_url'] = 'admin/posts/data_ajax';
// $this->data['posts'] = $this->post_model->get_datatable();
// dump($this->data['pages']);
// load view
$this->load->view('admin/posts/index', $this->data);
}
public function data_ajax() {
$this->output->enable_profiler(false);
echo $this->post_model->get_datatable();
// echo json_encode($this->post_model->get_datatable());
exit();
}
// the view
<table class="table dataTable table-bordered" cellspacing="0" width="100%">
<thead>
<tr>
<th>ID</th>
<th>Title</th>
<th>Url Slug</th>
<th>Sort Description</th>
<th>Status</th>
</tr>
</thead>
<tfoot>
<tr>
<th>ID</th>
<th>Title</th>
<th>Url Slug</th>
<th>Sort Description</th>
<th>Status</th>
</tr>
</tfoot>
<!-- <tbody>
<tr>
<td colspan="5" class="dataTables_empty"></td>
</tr>
</tbody> -->
</table>
<?php if(isset($datatables)): ?>
<?php echo js_tag('js/dataTables/jquery.dataTables.min.js'); ?>
<?php echo js_tag('js/dataTables/dataTables.bootstrap.min.js'); ?>
<script type="text/javascript">
$(document).ready(function() {
$('.dataTable').DataTable({
'bProcessing' : true,
'bServerSide' : true,
'sAjaxSource' : '<?php echo base_url($data_url); ?>',
'sServerMethod' : 'POST',
'fnServerData' : function (sSource, aoData, fnCallback) {
$.ajax({
dataType : 'json',
type : 'post',
url : sSource,
data : aoData,
success : fnCallback,
"columns": [
{ "data": "id" },
{ "data": "title" },
{ "data": "slug" },
{ "data": "sort_description" },
{ "data": "status" }
]
});
}
});
});
</script>
<?php endif; ?>
So if I access the data_ajax() function from the url like this
localhost/my-blog/admin/posts/data_ajax
and echo echo $this->page->get_datatable(); I can the records
{"draw":0,"recordsTotal":2,"recordsFiltered":2,"data":[{"id":"1","title":"First post","slug":"first-post","sort_description":"This is the first post","status":"visible"},{"id":"2","title":"Second post","slug":"second-post","sort_description":"This is the second post","status":"visible"}]}
but the problem is I can't display them on my screen. In addition I also get this warning in an alert box
DataTables warning: table id=DataTables_Table_0 - Requested unknown parameter '0' for row 0. For more information about this error, please see http://datatables.net/tn/4
This is a screenshot of what I get
How can I make this work properly? Any help would be appreciated

Answer 1

Please try this
Add Columns parameter to associate data with column
The code will be something like this
$('.dataTable').DataTable({
'bProcessing' : true,
'bServerSide' : true,
'sAjaxSource' : '<?php echo base_url($data_url); ?>',
'sServerMethod' : 'POST',
"columns": [
{ "data": "id" },
{ "data": "title" },
{ "data": "slug" },
{ "data": "date_published" },
{ "data": "status" }
]
'fnServerData' : function (sSource, aoData, fnCallback) {
$.ajax({
dataType : 'json',
type : 'post',
url : sSource,
data : aoData,
success : fnCallback,
});
}
});
Please refer datatables column, for details

I had similar problem. This is how I got it solved:
You have to set the columns as this
"columns": [null, null, null, null, null,{}]
Set it separately not in the Ajax.
