Php Prestashop在1中列出2种产品<；李>；

我有一个滑块，它列出了4

pr幻灯片

我想添加一个额外的行，这样它将显示2x4产品

为了实现这一目标，我需要列出2种产品公关。

我真的试着去修复它，但是我的代码和我计算产品的方式有问题

请看一看：`{if isset（$products）} {include file=“$tpl_dir./breadcrumb.tpl”} {assign var=count value=0}

    {foreach from=$products item=product name=products}

        {if $count == 0}
            <li style="position: relative;">
        {/if}
            <div id="ProductCon">
                <div class="prodimage"><a href="{$product.link|escape:'htmlall':'UTF-8'}" class="product_img_link" title="{$product.name|escape:'htmlall':'UTF-8'}"><img src="{$link->getImageLink($product.link_rewrite, $product.id_image, 'home')}" alt="{$product.legend|escape:'htmlall':'UTF-8'}" {if isset($homeSize)} width="{$homeSize.width}" height="{$homeSize.height}"{/if} /></a></div>
                <h3><a href="{$product.link|escape:'htmlall':'UTF-8'}" title="{$product.name|escape:'htmlall':'UTF-8'}">{$product.name|truncate:35:'...'|escape:'htmlall':'UTF-8'}</a></h3>
            </div>
            {if $count == 1}
                </li>
            {/if}
            {function name='counter2'}
                {$count+1}
            {/function}
    {/foreach}



    </ul>
</div>
<!-`

{foreach from=$products item=product name=products}
{如果$count==0}

{/if}
{如果$count==1}

{/if}
{function name='counter2'}
{$count+1}
{/函数}
{/foreach}

Smarty不是一种（完整的）编程语言，它是一个模板引擎。有些事情是故意不允许的

您应该使用smarty提供的道具，这样您就不必使用编程逻辑来实现您的目标

对于作业，您需要使用特殊的Smarty功能Smarty

对于smarty计数器，这应该可以工作：
{counter start=0 skip=1 assign=“count”}
{foreach from=$products item=product name=products}
{如果$count==0}

{/if}
{如果$count==1}

{/if}
{计数器}
{/foreach}
您可能可以检查foreach循环中的索引值。下面是一个你如何实现它的例子。这还会检查列表中是否有奇数个产品，并关闭最后一个产品的li标签。希望这有帮助

<ul>
    {foreach from=$products item=product name=products}
        {if $smarty.foreach.products.first == true || $smarty.foreach.products.index % 2 == 0}
            <li style="position: relative;">
        {/if}
            <div id="ProductCon">
                <div class="prodimage"><a href="{$product.link|escape:'htmlall':'UTF-8'}" class="product_img_link" title="{$product.name|escape:'htmlall':'UTF-8'}"><img src="{$link->getImageLink($product.link_rewrite, $product.id_image, 'home')}" alt="{$product.legend|escape:'htmlall':'UTF-8'}" {if isset($homeSize)} width="{$homeSize.width}" height="{$homeSize.height}"{/if} /></a></div>
                <h3><a href="{$product.link|escape:'htmlall':'UTF-8'}" title="{$product.name|escape:'htmlall':'UTF-8'}">{$product.name|truncate:35:'...'|escape:'htmlall':'UTF-8'}</a></h3>
            </div>
        {if $smarty.foreach.products.index % 2 == 1 || $smarty.foreach.products.last == true}
            </li>
        {/if}
    {/foreach}
</ul>


{foreach from=$products item=product name=products}
{如果$smarty.foreach.products.first==true | |$smarty.foreach.products.index%2==0}

{/if}
{如果$smarty.foreach.products.index%2==1 | |$smarty.foreach.products.last==true}

{/if}
{/foreach}

修改前是否可以共享当前模板代码？
<ul>
    {foreach from=$products item=product name=products}
        {if $smarty.foreach.products.first == true || $smarty.foreach.products.index % 2 == 0}
            <li style="position: relative;">
        {/if}
            <div id="ProductCon">
                <div class="prodimage"><a href="{$product.link|escape:'htmlall':'UTF-8'}" class="product_img_link" title="{$product.name|escape:'htmlall':'UTF-8'}"><img src="{$link->getImageLink($product.link_rewrite, $product.id_image, 'home')}" alt="{$product.legend|escape:'htmlall':'UTF-8'}" {if isset($homeSize)} width="{$homeSize.width}" height="{$homeSize.height}"{/if} /></a></div>
                <h3><a href="{$product.link|escape:'htmlall':'UTF-8'}" title="{$product.name|escape:'htmlall':'UTF-8'}">{$product.name|truncate:35:'...'|escape:'htmlall':'UTF-8'}</a></h3>
            </div>
        {if $smarty.foreach.products.index % 2 == 1 || $smarty.foreach.products.last == true}
            </li>
        {/if}
    {/foreach}
</ul>
