硬编码 ps_socialfollow.tpl 以支持多语言后出现 Smarty 错误

Question

我的 prestashop 版本是 php 7.1 上的 1.7.3.4。

这是ps_socialfollow.tpl的默认内容：

 {block name='block_social'}
  <div class="social_follow">
    <ul>
      {foreach from=$social_links item='social_link'}
        <li class="{$social_link.class}"><a href="{$social_link.url}" target="_blank">{$social_link.label}</a></li>
      {/foreach}
    </ul>
  </div>
{/block}

模块默认不支持多语言。所以我硬编码它以支持这样的多语言：

{block name='block_social'}
{if $language.language_code == 'en-us'}
 <div class="social_follow">
    <ul>
        <li class="facebook"><a href="" target="_blank">{$social_link.label}</a></li>
        <li class="twitter"><a href="" target="_blank">{$social_link.label}</a></li>
        <li class="instagram"><a href="" target="_blank">{$social_link.label}</a></li>
        <li class="googleplus"><a href="" target="_blank">{$social_link.label}</a></li>
        <li class="pinterest"><a href="" target="_blank">{$social_link.label}</a></li>
    </ul>
  </div>

{elseif $language.language_code == 'ko'}
  <div class="social_follow">
    <ul>
        <li class="facebook"><a href="" target="_blank">{$social_link.label}</a></li>
        <li class="twitter"><a href="" target="_blank">{$social_link.label}</a></li>
        <li class="instagram"><a href="" target="_blank">{$social_link.label}</a></li>
        <li class="googleplus"><a href="" target="_blank">{$social_link.label}</a></li>
        <li class="pinterest"><a href="" target="_blank">{$social_link.label}</a></li>
    </ul>
  </div>

{/if}

{/block}

只要我不激活调试模式，它就可以完美运行。激活调试模式后，我收到此错误消息：

我对php的了解甚至不值一提，因为它更多的是基于我能够做到的一点点逻辑思维，而不是实际知识。因此，我无法自行修复 smarty 错误。

我需要做哪些修改？在此模块中实现多语言（网站）支持的正确方法是什么？

我已经根据 Alexander Grosul 的建议编辑了 ps_socialfollow.tpl。

  <div class="social_follow">
    <ul>
        <li class="facebook"><a href="" target="_blank">{$social_link.facebook.label}</a></li>
        <li class="twitter"><a href="" target="_blank">{$social_link.twitter.label}</a></li>
        <li class="instagram"><a href="" target="_blank">{$social_link.instagram.label}</a></li>
        <li class="googleplus"><a href="" target="_blank">{$social_link.googleplus.label}</a></li>
        <li class="pinterest"><a href="" target="_blank">{$social_link.pinterest.label}</a></li>
    </ul>
  </div>

结果是完全相同的聪明错误。

我也试过这个版本：

{block name='block_social'}
  <div class="social_follow">
    <ul>
      {foreach from=$social_links item='social_link'}

{if $language.language_code == 'en-us'}
         <li class="facebook"><a href="" target="_blank">{$social_link.label}</a></li>
        <li class="twitter"><a href="" target="_blank">{$social_link.label}</a></li>
        <li class="instagram"><a href="" target="_blank">{$social_link.label}</a></li>
        <li class="googleplus"><a href="" target="_blank">{$social_link.label}</a></li>
        <li class="pinterest"><a href="" target="_blank">{$social_link.label}</a></li>



{elseif $language.language_code == 'ko'}
        <li class="facebook"><a href="" target="_blank">{$social_link.label}</a></li>
        <li class="twitter"><a href="" target="_blank">{$social_link.label}</a></li>
        <li class="instagram"><a href="" target="_blank">{$social_link.label}</a></li>
        <li class="googleplus"><a href="" target="_blank">{$social_link.label}</a></li>
        <li class="pinterest"><a href="" target="_blank">{$social_link.label}</a></li>

{/if}

{/foreach}
 </ul>
  </div>
{/block}

这并没有触发聪明的错误，只是显示了所有的图标。一次，不管选择的语言。

Answer 1

在您的示例中，默认版本中有循环，但修改后的版本中没有。这意味着您不能使用 $social_link 因为它在那里不存在，它是在循环中创建的。您只能使用传入的 $social_links 并指出您要使用此数组的哪个元素，例如 $social_links.twitter.label 等
