Hi all I am trying to use a datatable to reflect my database but I am not getting the result in the datatable. Help needed!!!
My Controller:-
public function __construct() {
parent::__construct();
$this->load->library('Datatables');
$this->load->library('table');
$this->load->database();
}
function index()
{
//set table id in table open tag
$tmpl = array ( 'table_open' => '<table id="big_table" border="1" cellpadding="2" cellspacing="1" class="mytable">' );
$this->table->set_template($tmpl);
$this->table->set_heading('Student ID','Name','Student Code','Class');
$this->load->view('subscriber_view');
}
//function to handle callbacks
function datatable()
{
$this->datatables->SELECT ('*', 'class')
->unset_column('student_id')
-> FROM ('students as s1')
->join ('student_class as s2','s1.class_id = s2.class_id');
echo $this->datatables->generate();
}
}
My View:-
<html>
<head>

'success' : fnCallback
});
}
} );
} );
</script>
<h1>Student Management</h1>
<?php echo $this->table->generate(); ?>
</div>
</body>
</html>
My Output:-
{"sEcho":0,"iTotalRecords":2,"iTotalDisplayRecords":2,"aaData":[["1","Ahmad","Niza","451","AA1","A1"],["2","Ahmadi","Reza","452","AA2","A2"]],"sColumns":"*"}
What is wrong with this code?
Thanks in advance for help.
