Codeigniter - MVC php - 从数据库中打印多值答案

【问题标题】：Codeigniter - MVC php - print multi value from databaseCodeigniter - MVC php - 从数据库中打印多值
【发布时间】：2020-02-25 13:01:14
【问题描述】：

我将 MVC 与 Codeigniter 一起使用，并尝试从 HTML 文件上的数组（使用数据库中的值）打印。在每一行中，我需要将 Uniq URL 行打印到标签中。

型号：

<?php

class product_model extends CI_Model
{

      public function __construct()
     {
                parent::__construct();
                $this->load->database();
     }
      public function get_product()
      {
            $query = $this->db->query('SELECT * FROM `product`');
//            var_dump($query->result_array());
            return $query->result_array();   

      }


}

控制器：

<?php

class webs_controller extends CI_Controller{
public function __construct()
{
                parent::__construct();
                $this->load->model('login_model');
                $this->load->model('product_model');
                $this->load->helper('url_helper');
                $this->load->helper('form');
                $this->load->library('session');

}       
        public function view($page = 'home')
        {
             if ( ! file_exists(APPPATH.'views/pages/'.$page.'.php'))
            {
                    // Whoops, we don't have a page for that!
                    show_404();
            }
            $data['title'] = ucfirst($page); // Capitalize the first letter

            $this->load->view('templates/header', $data);
            $this->load->view('pages/'.$page, $data);
            $this->load->view('templates/footer', $data);
        }

        public function home()
        {        
                $data['user'] = $this->session->all_userdata();
                $this->load->view('templates/header', $data);
                $this->load->view('pages/home', $data);
                $this->load->view('templates/footer');          
        }
            public function products()
        {        
                $data['user'] = $this->session->all_userdata();
                $this->load->view('templates/header', $data);
                $this->load->view('pages/our_products', $data);
                $this->load->view('templates/footer');

        }
            public function contact()
        {        
                $data['user'] = $this->session->all_userdata();
                $this->load->view('templates/header', $data);
                $this->load->view('pages/contact', $data);
                $this->load->view('templates/footer');

        }

        public function our_products(){

            $data['title'] = 'Produts';  
            $data['user'] = $this->session->all_userdata();
            $data['product'] = $this->product_model->get_product();
            $this->load->view('templates/header', $data);
            $this->load->view('pages/our_products',$data);
            $this->load->view('templates/footer');   

        }


}

数据库：

我需要什么： 我需要从我的数组中的特定路由打印每个src="<?php echo base_url('assets/img/products/img-1.jpg'); ?>" 行 - 我从控制器函数中获得：

        public function our_products(){
           $data['title'] = 'Produts';  
           $data['user'] = $this->session->all_userdata();
           $data['product'] = $this->product_model->get_product();
           $this->load->view('templates/header', $data);
           $this->load->view('pages/our_products',$data);
           $this->load->view('templates/footer');   

       }

喜欢：src="<?php echo $product[0]['item_img'] ?>" 以及我需要移动到下一个索引的每个标签。我尝试使用 foreach 但它是多个所有 html 代码

希望我以自己为榜样！谢谢。

【解决方案1】：

<table>
    <thead>
        <tr>
            <td>Serial number</td>
            <td>item_name</td>
            <td>item_price</td>
            <td>item_count</td>
            <td>item_color</td>
            <td>item_size</td>
            <td>image</td>
        </tr>
    </thead>
    <tbody>
        <?php foreach ($product as $item) : ?>
            <tr>
                <td><?= $item['serial_number'] ?></td>
                <td><?= $item['item_name'] ?></td>
                <td><?= $item['item_price'] ?></td>
                <td><?= $item['item_count'] ?></td>
                <td><?= $item['item_color'] ?></td>
                <td><?= $item['item_size'] ?></td>
                <td><img src="<?= $item['oitem_img'] ?>" alt=""></td>
            </tr>
        <?php endforeach; ?>
    </tbody>
</table>

类似的东西？

【讨论】：

我必须使用我的模板 html .. 不能使用表格

【解决方案2】：

我修好了！像这样使用 foreach：

<section class="content-section">
        <h2 class="section-header">Women</h2>
        <div class="shop-items">
        <?php foreach ($product as $item) : ?>
            <div class="shop-item">
            <span class="shop-item-title"><?php echo $item['item_name'] ?> 1</span>
                <img class="shop-item-image" src="<?php echo $item['item_img'] ?>">
                <div class="shop-item-details">
                    <span class="shop-item-price" style="font-weight: bold;" style="font-weight: bold;">
                        $12.99&nbsp&nbsp&nbsp</span>
                    <button class="btn btn-primary shop-item-button" type="button">ADD TO CART</button>
                </div>
            </div>
        <?php endforeach; ?>
        </div>
</section>

只是循环了代码。它每轮都会打印我的数组索引+1！
