Php Smarty-foreach循环4次并创建一个新列表

我想用smarty实现这样一个列表

<ul>
 <li>
   <a>img1</a>
   <a>img2</a>
   <a>img3</a>
   <a>img4</a>
 </li>
 <li>
   <a>img5</a>
   <a>img6</a>
   <a>img7</a>
   <a>img8</a>
 </li>
<li>
   <a>img9</a>
   <a>img10</a>
   <a>img11</a>
   <a>img12</a>
 </li>
</ul>

{/if}
{/foreach}

首先，对于给定的数组$manufacturers，它将在

内循环最多4次，并将创建4个

。然后，当它到达第四个索引时，它将生成一个新的

标记

谢谢你的帮助

要在每个li标记中显示4个图像吗

<ul>
{foreach from=$manufacturers item=manufacturer name=manufacturer_list}
  {if $smarty.foreach.manufacturer_list.index % 4 == 0}
    <li>
  {/if}

  <a><img></a>

  {if $smarty.foreach.manufacturer_list.index % 4 == 0 || $smarty.foreach.manufacturer_list.last}
    </li>
  {/if}
{/foreach}
</ul>

{foreach from=$manufacturers item=制造商名称=制造商\列表}
{如果$smarty.foreach.manufacturer_list.index%4==0}

{/if}
{如果$smarty.foreach.manufacturer_list.index%4==0 | |$smarty.foreach.manufacturer_list.last}

{/if}
{/foreach}

Im Smarty3语法您可以执行以下操作：

{$data = [
    "alpha", "bravo", "charlie", "delta", "echo", "foxtrot", "golf", 
    "hotel", "india", "juliet", "kilo", "lima", "mike", "november", 
    "oscar", "papa", "quebec", "romeo", "sierra", "tango", "uniform", 
    "victor", "whiskey", "x-ray", "yankee", "zulu"
]}

{foreach $data as $value}
  {if $value@first}
    <ul>
      <li>
  {elseif ($value@iteration - 1) is div by 4}
      </li><li>
  {/if}

  <span>{$value}</span>

  {if $value@last}
      </li>
    </ul>
  {/if}
{/foreach}

{$data=[
“阿尔法”，“布拉沃”，“查理”，“三角洲”，“回声”，“狐步”，“高尔夫”，
“酒店”、“印度”、“朱丽叶”、“基洛”、“利马”、“迈克”、“十一月”，
“奥斯卡”，“爸爸”，“魁北克”，“罗密欧”，“塞拉”，“探戈”，“制服”，
“维克多”，“威士忌”，“x光”，“扬基”，“祖鲁”
]}
{foreach$data as$value}
{如果$value@first}


{elseif($value@iteration-1）被4}除掉

{/if}
{$value}
{如果$value@last}


{/if}
{/foreach}

---

请注意，由于将整个

嵌套在foreach循环中，因此它不会显示是否没有要循环的数据。

迭代-1

为什么不直接使用索引？因为您可能正在迭代一个映射（关联数组/字符串键），而该映射不适用于索引。

{$data = [
    "alpha", "bravo", "charlie", "delta", "echo", "foxtrot", "golf", 
    "hotel", "india", "juliet", "kilo", "lima", "mike", "november", 
    "oscar", "papa", "quebec", "romeo", "sierra", "tango", "uniform", 
    "victor", "whiskey", "x-ray", "yankee", "zulu"
]}

{foreach $data as $value}
  {if $value@first}
    <ul>
      <li>
  {elseif ($value@iteration - 1) is div by 4}
      </li><li>
  {/if}

  <span>{$value}</span>

  {if $value@last}
      </li>
    </ul>
  {/if}
{/foreach}
