在category.tpl中获取prestashop中当前类别的同级类别 [英] Get sibling categories in category.tpl for the current category in prestashop

问题描述

我需要在Prestashop主题的类别页面中列出兄弟类别。目前，它确实显示子类别，但不是同级类别。

I need to list sibling categories in the category page in a Prestashop theme. Currently it does show the sub-categories if any but not the sibling categories.

一个快速答案确实不胜感激！谢谢。

A quick answer would really be appreciated! Thanks.

推荐答案

首先，我会在/ override / controllers /中创建一个覆盖文件，名为CategoryController.php

For to start i would have created a override file in /override/controllers/, named CategoryController.php

并添加以下内容：

<?php

class CategoryController extends CategoryControllerCore
{
    public function displayContent()
    {
        // Get the global smarty object.
        global $smarty;

        // Get current category's parent.
        $parent_category = new Category($this->category->id_parent, self::$cookie->id_lang);

        // Get parent category's subcategories (which is current category's siblings, including it self).
        $category_siblings = $parent_category->getSubCategories((int)self::$cookie->id_lang)

        /* Assign your siblings array to smarty. */
        $smarty->assign(
            array(
                "category_siblings" => $category_siblings
            )
        );

        /* This we run the normal displayContent, but pass the siblings array to
           category.tpl */
        parent::displayContent();
    }
}

?>

我这是基本的操作方式，我还没有测试过。您需要找到一种不在同级列表中列出当前类别的方法。

I this the basic way to do it, i have not tested it get. You need to find a way to not list current category in the list of siblings.

如果代码有效，您现在将在category.tpl中有一个名为category_siblings的数组，您现在需要例如复制输出子类别的category.tpl中的代码，并用category_siblings数组替换子类别arra。

If the code works you will now have an array in category.tpl named category_siblings, you now need to for example copy the code in category.tpl that outputs the subcategories and replace the subcategories arra with the category_siblings array.
