join函数只回显数据库的1个产品

我创建了一个模型函数，因此它将回显属于我单击的配置文件用户的产品，这只是该用户得到回应的第一个产品。例如，我有一个帐户，上传了总共7个产品，该功能只显示页面上的第一个产品..

这是模型功能：

function getdata_aangeboden($user_id){
  $this->db->select("users.*,products.*"); 
  $this->db->from('users');
  $this->db->join('products','products.user_id = users.user_id','left');
  $this->db->where('users.user_id', $user_id);
  $query = $this->db->get();
  return $query->result();
 } 

    // Gets a list of multiple users.
 function getdata($user_id){
  $this->db->select("*"); 
  $this->db->from('users');
  $this->db->where('user_id', $user_id);
  $query = $this->db->get();
  return $query->result();
 }

控制器功能：

<?php foreach($products as $product) { ?> 
  <div class="main-gifts">
      <a href="<?php echo base_url() ?>/Product/details/<?php echo $product->product_id; ?>">
        <img id="fotos" src="<?php echo base_url(); ?>upload/<?php echo $product->product_foto_thumb; ?>">
        </a>
        <div class="products_discription">
            <h3><?php echo $product->product_naam; ?></h3>
            <div class="ophaal_plaats">
                <p>Plaats: <?php  echo $product->ophaal_plaats; ?></p>
            </div>
            <div class="aangeboden_door">
            <p> <?php  
                    foreach($userdetail_list as $row){ ?>
              <tr>
                  <td><?php echo $row->voornaam;?></td>
               </tr>
                    <?php } ?></p>
          </div>
          <div class="status">
          </div>
      </div>
        <a href="<?php echo base_url() ?>/KdGwController/details_bewerken/<?php echo $product->product_id; ?>"><input type="button" class="btn btn-default cb" value="Cadeau bewerken"></input> </a>
  </div>
 <?php } ?>

有人可以向我解释为什么它只显示1个产品而不是所有属于同一个user_id的产品？ 感谢

当我打印$ products：

我希望你能正确地声明foreach循环。

<?php foreach($products as $product) {
     // print here the product info
}
?>

答案 1 :(得分：1)

您需要按如下方式更改查询

function getdata($user_id){
  $this->db->select("products.*,users.*"); 
  $this->db->from('products');
  $this->db->join('users','users.user_id = products.user_id','left');
  $this->db->where('users.user_id', $user_id);
  $query = $this->db->get();
  return $query->result();
 }

答案 2 :(得分：0)

我发现你只放了

  

TR

标签，但不是

  

表

标签，这可能会导致问题，所以请查看下面的答案

<?php 
  foreach($products as $product) { ?>
    <div class="main-gifts">
        <a href="<?php echo base_url() ?>/Product/details/<?php echo $product->product_id; ?>">
            <img id="fotos" src="<?php echo base_url(); ?>upload/<?php echo $product->product_foto_thumb; ?>">
        </a>
        <div class="products_discription">
            <h3><?php echo $product->product_naam; ?></h3>
            <div class="ophaal_plaats">
                <p>Plaats: <?php  echo $product->ophaal_plaats; ?></p>
            </div>
            <div class="aangeboden_door">
                <p> 
                    <table>
                    <?php
                    foreach($userdetail_list as $row){ ?>
                        <tr>
                            <td><?php echo $row->voornaam;?></td>
                        </tr>
                    <?php } ?>
                    </table>
                </p>
