Question

我正在尝试制作产品详情页面。因此，当用户在产品页面上时，他们可以点击特定产品以查看产品的详细信息，但我收到了一些错误。

这是我正在加载所有产品的所有产品视图页面：

public function details($product_id) {
     //vraag product details
     $data['product'] = $this->Product_model->get_product_details($product_id);

     //laad view
     $data['main_content'] = 'details';
     $this->load->view('details',$data);
 }

这是产品详细信息控制器功能：

<div class="container">
<div class="row">
<div><?php echo $product->product_naam; ?></div>
    <div class="col-md-4">
          <img src="<?php echo base_url().'upload/'.$product['product_foto'] ?>" class="img-responsive">
    </div>
</div>

这是产品详细信息视图页面：

public function get_product_details($product_id) {
        $this->db->select('*');
        $this->db->from('products');
        $this->db->where('id', $product_id);

        $query = $this->db->get();
        return $query->row();
    }

这是产品详细模型功能：

时

$pcname = explode("\r", file_get_contents("PCNAMES2.txt"));
foreach($pcname as $pc) {
    echo "\\".$pc."\c$";
}

Answer 1

很简单。问题是你错误地调用了details($productid)方法。要解决此问题，请在所有产品页面中添加<a>标记中的产品ID。见下面的代码。

<?php foreach($products as $product) : ?>
    <div class="col-lg-2">
        <div id="product">
        <a href="<?php echo base_url() ?>/Product/details/<?php echo $product['id']; ?>">
            <?php  echo '<img src="upload/'.$product['product_foto'].'">' ; ?>
        </a>
        <div class="product_naam"><?php echo $product['product_naam']; ?></div>
        <div class="ophaal_plaats">
           <?php  echo $product['ophaal_plaats']; ?>
        </div>
        <div class="aangeboden_door">
            <p>Aangeboden door: Peter</p>
        </div>
        </div>
        </div>
<?php endforeach; ?>

Answer 2

这应该是您的视图代码（与上面的答案相同）：并且请确保“$ products”包含名为“id”的密钥。

<?php foreach($products as $product) : ?>
    <div class="col-lg-2">
        <div id="product">
        <a href="<?php echo base_url() ?>/Product/details/<?php echo $product['product_id']; ?>">
            <?php  echo '<img src="upload/'.$product['product_foto'].'">' ; ?>
        </a>
        <div class="product_naam"><?php echo $product['product_naam']; ?></div>
        <div class="ophaal_plaats">
           <?php  echo $product['ophaal_plaats']; ?>
        </div>
        <div class="aangeboden_door">
            <p>Aangeboden door: Peter</p>
        </div>
        </div>
        </div>
<?php endforeach; ?>

然后在控制器中按以下方式更改：

public function details() {  //Remove product id from arguments
     $product_id = $this->uri->segment('3');
     $data['product'] = $this->Product_model->get_product_details($product_id);
     $data['main_content'] = 'details';
     $this->load->view('details',$data);
 }

请注意，您必须加载URL帮助程序，以防出现错误：

$this->load->helper('url');

无法在CodeIgniter中加载产品详细信息页面
