我试图传递一个数组，当从数据库中查询它时，它会被初始化。
我试图传递并在视图中显示的产品数组只是抛出了一个错误，我不知道为什么。我使用的是codeigniter 3。

产品型号.php

function get_all_products()
    {
        $this->db->select("produceCode,description,category,supplier, quantityInStock, bulkSalePrice,photo");
        $this->db->from('products');
        $query = $this->db->get();
        return $query->result();
        
    }

产品控制器.php

public function listProducts()
    {
        $data['p']=$this->ProductsModel->get_all_products(/*2, $this->uri->segment(3)*/);
        $this->load->view('products',$data);
    }

产品.php

<?php foreach( $p as $row) { ?> // line of code thats causing the error
            <div class="col-md-3">
                <div class="card p-3">
                    <div class="text-center"> <!--<img src="../assets/images/products/thumbs/--><?php /*$row->photo;*/?>" width="200"> </div>
                    <div class="product-details"> <span class="font-weight-bold d-block">$ 7.00</span> <span><?php echo 'hi'/*$row->description;*/?></span>
                        <div class="buttons d-flex flex-row">
                            <div class="cart"><i class="fa fa-shopping-cart"></i></div> <button class="btn btn-success cart-button btn-block"><span class="dot">1</span>Add to cart </button>
                        </div>
                    </div>
                </div>
            </div>
            <?php } ?>

任何建议都很好
