你好，我把桌子放在这里

此处的屏幕截图

Summary Table Main Table 现在我要在摘要表中，如果“ Menge” = 0，则摘要中不会出现可疑行，这意味着在实际图片中，只有“ 10.95：7”才能显示摘要表的当前表代码

create.topic.policy.class.name

和类函数

    <div class="box">
      <div class="box-header">
      <h3 class="box-title">Zusammenfassung</h3>
      </div>
      <div class="box-body">
        <table class="table table-bordered table-striped">
          <tr>
            <th>Ware</th>
            <th>Menge</th>
          </tr>
          <tbody>
            <tr>
              <td>4.95</td>
              <td><?php echo $count->countRow($lid, 4.95); ?></td>
            </tr>
            <tr>
              <td>5.95</td>
              <td><?php echo $count->countRow($lid, 5.95); ?></td>
            </tr>
            <tr>
              <td>7.95</td>
              <td><?php echo $count->countRow($lid, 7.95); ?></td>
            </tr>
            <tr>
              <td>9.95</td>
              <td><?php echo $count->countRow($lid, 9.95); ?></td>
            </tr>
            <tr>
              <td>10.95</td>
              <td><?php echo $count->countRow($lid, 10.95); ?></td>
            </tr>
            <tr>
              <td>11.95</td>
              <td><?php echo $count->countRow($lid, 11.95); ?></td>
            </tr>
            <tr>
              <td>12.95</td>
              <td><?php echo $count->countRow($lid, 12.95); ?></td>
            </tr>
          </tbody>
        </table>
      </div>
    </div>

表格功能可显示带有用户信息的主表格

public function countRow($lid, $price){
    $result = $this->sql->query("SELECT count(*) FROM lieferschein2_ware where ean = '$price' and l_id = $lid");
    $res = mysqli_fetch_array($result);

    if($result->num_rows === 0){
        return 0;
    }else{
        return $res["count(*)"];
    }
}

您需要在每一行之前应用if条件，以检查menge是否大于0，如下所示：

<div class="box">
      <div class="box-header">
      <h3 class="box-title">Zusammenfassung</h3>
      </div>
      <div class="box-body">
        <table class="table table-bordered table-striped">
          <tr>
            <th>Ware</th>
            <th>Menge</th>
          </tr>
          <tbody>
            <?php if ($count->countRow($lid, 4.95) > 0) { ?>
            <tr>
              <td>4.95</td>
              <td><?php echo $count->countRow($lid, 4.95); ?></td>
            </tr>
            <?php } ?>           
          </tbody>
        </table>
      </div>
    </div>

并且您需要为每行应用此if条件。
