[vitty95]

findParent() function find array. There could be one array or more than one.Now I want to make if statement depends on the number of array.How can I make if statement using the number of array?\[code\]function findParent($order_id){ ... $Q = $this->db->get('omc_order_item'); if ($Q->num_rows() > 0){ foreach ($Q->result_array() as $row){ $data[] = $row; } } ... return $data; }\[/code\]I tried this, but it does not work.\[code\]function deleteitem($order_id){ $childless = $this->MOrders->findParent($order_id); if ($childless<2){ $data['childlessorder']= $this->MOrders->findParent($order_id);...\[/code\]It must be checking if $childless is less than 2.How can I change it so that it will check the number of array is 1 (can be less than 2, doesn't it?)
