Fix if sRangeSeparator dont exist, ignore date range
What about developers than need the information of the query for a extended control, like print reports, stadistics, etc.. They need a way to access the query and get the list of nodes and name of columns, so I think add 2 new methods:
Added return_results(), similar to produce_output() but instead convert the list in JSON, it is return.
return array('aaData'=>$aaData,'sColumns'=>$sColumns);
Added request(), similar to generate() but is the public method to access to the query result, without paging to return all.
Controller example for use:
---------------------------------------
...
function my_csv_list(){
$this->load->helpers('datatables_helper');
$this->datatables->select("field1,field2,field3")
->from('table');
$results = $this->datatables->request();
$data['aaData'] = $results['aaData'];
$data['sColumns'] = $results['sColumns'];
//Example to produce a report in CSV format
$this->load->view('downloads/csv',$data);
}
-------------------
View downloads/csv:
<?
header('Content-Encoding: UTF-8');
header('Content-type: text/csv; charset=UTF-8');
header('Content-Disposition: attachment; filename=list.csv');
echo "\xEF\xBB\xBF";
if(!empty($sColumns)) echo implode(",",$sColumns)."\r\n";
if(!empty($aaData)) foreach($aaData as $ad){
echo implode(",",$ad)."\r\n";
}
