hi, i want to ask how to make server side datatables using costum filter on codeigniter.

this my model.php:

 function getUsers($postData = null)
  {
    $response = array();
    $draw = isset($postData['draw']);
    $start = isset($postData['start']);
    $rowperpage = isset($postData['length']); // Rows display per page
    $columnIndex = isset($postData['order'][0]['column']); // Column index
    $columnName = isset($postData['columns'][$columnIndex]['data']); // Column name
    $columnSortOrder = isset($postData['order'][0]['dir']); // asc or desc
    $searchValue = isset($postData['search']['value']); // Search value

    // Custom search filter 
    $searchDepartement = $postData['searchDepartement'];
    $searchCategory = $postData['searchCategory'];
    $searchMERGE_ITEM = $postData['searchMERGE_ITEM'];

    ## Search 
    $search_arr = array();
    $searchQuery = "";
    if ($searchValue != '') {
        $search_arr[] = " (departement like '%" . $searchValue . "%' or 
     category like '%" . $searchValue . "%' or 
     MERGE_ITEM like'%" . $searchValue . "%' ) ";
    }
    if ($searchDepartement != '') {
        $search_arr[] = "departement='" . $searchDepartement . "' ";
    }
    if ($searchCategory != '') {
        $search_arr[] = "category='" . $searchCategory . "' ";
    }
    if ($searchMERGE_ITEM != '') {
        $search_arr[] = "MERGE_ITEM like '%" . $searchMERGE_ITEM . "%' ";
    }
    if (count($search_arr) > 0) {
        $searchQuery = implode(" and ", $search_arr);
    }

    ## Total number of records without filtering

    DataTables uses a GET request by default, but your server-side script appears to be looking for POST data.

    Add:

    type: 'post'
    

    to your ajax object.
