how to send array of values to a query dynamically in codeigniter - codeigniter

Question

The code in model is
public function get_report6_8($type, $filter_id=NULL) {
$values = array($filter_id);
$select = '';
if ($filter_id && $type == 'jh') {
$select = 'and natbuild_rep.jh_rep_id = ?';
}
else if ($filter_id && $type == 'natbuild') {
$select = 'and natbuild_principal.id = ?';
}
$sql = "select sum(total) total
from (
select value_of_sale total
from lead
left join natbuild_rep
on natbuild_rep.mobile = lead.mobile
left join natbuild_store
on natbuild_store.id = natbuild_rep.store_id
left join natbuild_principal
on natbuild_principal.store_group = ifnull(natbuild_store.store_group2, natbuild_store.store_group)
where (status = 1 OR status = 2)
and value_of_sale is not null
{$select}
group by lead.id
) temp";
return $this->db->query($sql, $values)->row();
}
The code in controller is
$data['report8'] = $this->lead_report_model->get_report6_8($type, $this->input->post('filter'));
code in view is
Grand Total: $total)) ? $report8->total: 0;?>
if I run query like
select sum(total) total
from (
select value_of_sale total
from lead
left join natbuild_rep
on natbuild_rep.mobile = lead.mobile
left join natbuild_store
on natbuild_store.id = natbuild_rep.store_id
left join natbuild_principal
on natbuild_principal.store_group = ifnull(natbuild_store.store_group2, natbuild_store.store_group)
where (status = 1 OR status = 2)
and value_of_sale is not null
and natbuild_principal.id in (18, 30, 31, 35, 33, 25, 23, 15, 8, 6, 5, 29, 7, 3, 2, 1, 24, 27, 22, 21, 20, 26, 36)
group by lead.id ) temp
the result is right. please help how can I send array of values to the $select. This happens when I select grand total from a dropdown which contains all other values up there.

Answer 1

your dropdown is multiselect so it will pass an array with the values.
use
implode(",", $dropdownSelections);
$select = 'and natbuild_principal.id in ('.implode(",", $dropdownSelections).')';
