我想获得一个二维数组的数据,并使用smarty将其显示在html文件中: 这个想法如下:我的数组包含几个数组,每个数组都包含第一个偏移量中的类别名称和附加到此类别的链接

1-file php

$categories_links = array();//array that contains some catgories name with the attached links
//some dummy data
$categorie1="Horror movies";
$link11="http://www.movie11.com";
$link12="http://www.movie12.com";
$link13="http://www.movie13.com";
$categories_links[] = array($categorie1, $link11, $link12,$link13);
$categorie2="Action movies";
$link21="http://www.movie21.com";
$link22="http://www.movie22.com";
$categories_links[] = array($categorie2, $link21, $link22);
$smarty->assign('categories_links' , $categories_links );
$smarty->display('file.html');

2档html

{foreach key=categorie item=categorie from=$categories_links}
    foreach key=categorie item=categorie from=categorie}
 <!--
  1.display only the first item in every array as the category name
  2.display the rest as the links attached to the above category

//-->
  {/foreach}
{/foreach}

假设您使用Smarty 3(您还没有提及Smarty 2的任何内容),您可以使用以下代码:

{foreach $categories_links as $categorie}
<p>
    {foreach $categorie as $item}

        {if $item@first}
            <strong>Category name: {$item}</strong><br />
        {else}
            {$item}

        {/if}
    {/foreach}
</p>
{/foreach}

此输出将为:

Category name: Horror movies
http://www.movie11.com http://www.movie12.com http://www.movie13.com

Category name: Action movies
http://www.movie21.com http://www.movie22.com 

修改

正如你在评论中提到的,你想要Smarty 2的解决方案,你需要在你的Smarty模板文件中使用:

{foreach key=id item=categorie from=$categories_links}
    <p>
        {foreach item=item from=$categorie name=list}

            {if $smarty.foreach.list.first}
                <strong>Category name: {$item}</strong><br />
            {else}
                {$item}

            {/if}
        {/foreach}
    </p>
{/foreach}

这将为您提供输出:

Category name: Horror movies
http://www.movie11.com http://www.movie12.com http://www.movie13.com

Category name: Action movies
http://www.movie21.com http://www.movie22.com 

(与Smarty 3中的完全相同)

答案 1 :(得分:1)

我重构数据数组以使用类别名称作为键。

$categories = array(
  'Horror movies' => array(
    'link1',
    'link2',
    /...
  ),
  'Action movies' => array(
    'link1',
    'link2',
    /...
  ),
);
$smarty->assign("categories", $categories);

然后你可以在Smarty中轻松使用它

{foreach from=$categories key=category item=links}
  Category: {$category}
  {foreach from=$links item=link}
  {$link}
  {/foreach}
{/foreach}

使用这种方式要容易得多。
