在我的第一个模块中,Prestashop 的前台没有变化

No change in the front office in Prestashop in my first module

PrestaShop 的第一天。使用 PrestaShop 教程中的 PrestaShop 1.6: Creating a PrestaShop Module 我创建了一个模块(mymodule)。

但我没有看到前台有什么特别之处。 我的模块 列在模块列表中。安装并按照教程进行操作。但是前面还是没有变化(缓存也清空了)

\css\mymodule.css

div#mymodule_block_home p {
  font-size: 150%;
  font-style:italic;
}

\views\templates\hook\mymodule.tpl

<!-- Block mymodule -->
<div id="mymodule_block_home" class="block">
  <h4>Welcome!</h4>
  <div class="block_content">
    <p>Hello,
       {if isset($my_module_name) && $my_module_name}
           {$my_module_name}
       {else}
           World
       {/if}
       !       
    </p>   
    <ul>
      <li><a href="{$my_module_link}" title="Click this link">Click me!</a></li>
    </ul>
  </div>
</div>
<!-- /Block mymodule -->

现在我可以在后台看到 我的模块 的配置选项。 前面还是没什么区别。

等待您的帮助。谢谢。

可能是由于钩子名称不一致,您注册了 leftColumn 钩子,但是,自 1.5(我认为)以来的所有钩子都以 actiondisplay 开头。因此,尝试注册 displayLeftColumn 并拥有一个方法 hookDisplayLeftColumn 或将您当前的方法重命名为 hookLeftColumn.
