在我的第一个模块中，Prestashop 的前台没有变化

Question

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 -->

\mymodule.php

<?php

    // Load current value
    $helper->fields_value['MYMODULE_NAME'] = Configuration::get('MYMODULE_NAME');
     
    return $helper->generateForm($fields_form);
  }
  public function hookDisplayLeftColumn($params)
  {
    $this->context->smarty->assign(
      array(
          'my_module_name' => Configuration::get('MYMODULE_NAME'),
          'my_module_link' => $this->context->link->getModuleLink('mymodule', 'display')

  }
   
  public function hookDisplayHeader()
  {
    $this->context->controller->addCSS($this->_path.'css/mymodule.css', 'all');
  }   
}

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 action 或 display 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.
