按条件一循环显示不同产品

  • 772

我正在尝试按条件在一个周期中输入产品，在数据库中每个产品str1都有一个字段，我希望str1 == 0的产品显示在一个块中，str1 == 1的产品显示在另一个，但由于某种原因，我的 1 号街区的标题重复了 - 1 号餐厅：

 <?php foreach ($content->items as $item): ?>

      <?php if($item['str1'] == 0): ?>

        <h2>Ресторан №1</h2> 
        <tr class="odd views-row-first">
            <td class="views-field views-field-nothing">
          <img src="<?= $item['content']['image'] ?>" width="120" height="80">
                                                        <br>
    </td><td><?= $item['content']['name'] ?></td>
    <td class="views-field views-field-commerce-unit-price views-align-left price">
    <?= $item['price']/* - ceil(($item['price'] * 7) / 100)*/ ?> руб.          </td>
<td class="views-field views-field-edit-quantity">
        <?= $item['count'] ?>
</td>

    <td class="views-field views-field-commerce-total views-align-left price">
  <span class=""><?= $item['price'] *  $item['count'] /*- ceil((($item['price'] *  $item['count']) * 7) / 100)*/ ?></span>           </td>
   <td class="text-center"><span class="glyphicon glyphicon-trash trash cart-delete" data-cart="<?= $item['id'] ?>" title="Удалить"></span></td>
    <td>
 </td>
</tr>

   <?php endif; ?>

   <?php if($item['str1'] == 1): ?>

    <h2>Ресторан №2</h2> 
  <tr class="odd views-row-first">
  <td class="views-field views-field-nothing">
   <img src="<?= $item['content']['image'] ?>" width="120" height="80">
    <br>
  </td><td><?= $item['content']['name'] ?></td>
   <td class="views-field views-field-commerce-unit-price views-align-left price">
  <?= $item['price']/* - ceil(($item['price'] * 7) / 100)*/ ?> руб.          </td>
  <td class="views-field views-field-edit-quantity">
   <?= $item['count'] ?>
 </td>

    <td class="views-field views-field-commerce-total views-align-left price">
   <span class=""><?= $item['price'] *  $item['count'] /*- ceil((($item['price'] *  $item['count']) * 7) / 100)*/ ?></span>           </td>
<td class="text-center"><span class="glyphicon glyphicon-trash trash cart-delete" data-cart="<?= $item['id'] ?>" title="Удалить"></span></td>
  <td>
                                                            </td>
                                                        </tr>

    <?php endif; ?>

   <?php endforeach; ?>

    创建一个数组，其中键将表示“str1”，事实证明您将通过此参数对所有元素进行分组。

    array[
  "str1" => [
    item1,
    item2
  ],
  "str2" => [
    item3,
    item4
  ]
]

    在模板中已经双循环输出其块中的每个 str1 之后

    //контроллер
$array = array();
foreach ($content->items as $key => $item){
    $array[$item['str1']][$key] = $item;
}

// view
<?php foreach ($array as $keys):?>
    <div style="background: red; padding: 15px;">
        <?php foreach ($keys as $item): ?>
            <div><?=$item['content']['name']?></div>
        <?php endforeach; ?>
    </div>
<?php endforeach;?>

    像这样的东西

    array[
  "str1" => [
    "title" => "Заголовок 1",
    "values" => [
       item1,
       item2
    ]
  "str2" => [
    "title" => "Заголовок 2",
    "values" => [
       item3,
       item4
    ]
]
