[SOLVED] Deleting data from two tables simultaneously

[eluser]ninjayan[/eluser]
I also have the same problem. Deleting data from 2 tables. Here's the code:

Code:

$tables = array('documents', 'document_details');
$delete_transaction = $this->db->where('reference_number', $this->input->post('delete_reference_number'))->delete($tables);
if ($delete_transaction)
{
return true;
}
else
{
return false;
}

Data gets deleted however, it returns false.
