我已经为客户建立了一个Prestashop 1.7网站，我每天都会用脚本导入他的新产品。如果这些产品尚不存在，我会将其分类。我的问题是新创建的类别放在下拉菜单的末尾，按字母顺序显示它们会好得多。我知道我可以通过将它们拖放到后台办公室来做到这一点，但我希望我的脚本能够自动完成。
我已经覆盖Category.php类进行其他更改，因此我可以编辑此文件。我尝试更改了从ORDER BY或depth到position找到的每个name条款。它有一些效果，因为类别确实按名称排序，但很多只是从菜单中消失（即按照按位置排序的10个类别中，只有4个按名称排序）。
你知道实现这个目标的方法吗？

你可以这两种方式做到这一点。 我的方法是在创建菜单时执行此操作，这样就可以按照每种语言进行排序。为此，只需对ps_mainmenu模块使用此覆盖：
use PrestaShop\PrestaShop\Core\Module\WidgetInterface;
class Ps_MainMenuOverride extends Ps_MainMenu implements WidgetInterface
{
protected function generateCategoriesMenu($categories, $is_children = 0)
{
$categories = $this->sortCategories($categories);
return parent::generateCategoriesMenu($categories, $is_children);
}
public function sortCategories($categories)
{
uasort($categories, 'cmpcat');
foreach($categories as $k => $category)
{
if (isset($category['children']) && !empty($category['children'])) {
$children = $this->sortCategories($category['children']);
$categories[$k]['children'] = $children;
}
}
return $categories;
}
}
function cmpcat($a, $b) {
return strcmp($a['name'], $b['name']);
}
另一个选项是在创建菜单时进行排序。但我必须看到当前的导入代码，即便如此也可能更难。
这适用于儿童类别。对于主要类别，有必要覆盖另一个函数。

问题是查询，例如，如果子类别名称以a开头，父类别以b开头，则prestashop没有显示它，则必须添加主“ order by”，在这种情况下：level_depth。 / p>
我希望我的替代代码会有用：

continue;
