那是我的pos_view。 我的系统是关于销售点的。 这是用户搜索产品的地方 控制器
public function pos(){
$this->load->model('item_model');
$data['names'] = $this->item_model->get_all_item();
$data['item_name'] = $this->item_model->getProduct();
$this->load->view('pos_view',$data);
}
}
我的模特
public function item_info($itemName) {
$this->load->database();
$sql = $this->db->where('prod_id', urldecode($itemName))->get('products');
return $sql->row();
}
public function getProduct(){
$this->load->database();
$sql = $this->db->get('products');
return $sql->result();
}
