我的项目是使用Web服务添加类别的,当我刷新类别文件时,它会创建与以前相同的类别。

  foreach ($XMLRSString->Families->Family as $family)
        {   
            $categories = $family->Code;

            $exists = Db::getInstance(_PS_USE_SQL_SLAVE_)->executeS('select id_category from ps_category where id_category = "'.$categories['id_category'].'"');

                $category = new Category((int)$categories);

                $category->id=  (int)$categories;

                $category->id_category_default=(int)$family->Code;

                $category->force_id = true;

                $category->is_root_category = false;

                $category->name = array((int)Configuration::get('PS_LANG_DEFAULT') => $family->Designation);

                $category->link_rewrite = array((int)Configuration::get('PS_LANG_DEFAULT') =>  $family->Code);

                $category->id_parent = Configuration::get('PS_HOME_CATEGORY');

                if($exists){
                    $category->add();
                    echo "created ".$family->Code."<br>";
                }
                else{
                    $category->save();
                    echo "already exists ".$family->Code."<br>";
                }
        }

它没有出现任何错误,但没有显示在PrestaShop类别中

无需使用if ($exists),因为$category->save();将已经检查类别是否存在,如果存在则将对其进行更新,否则将创建该类别。

您可以参考有关此主题的上一个问题: How to test if a category already exists? PrestaShop

我认为您的问题源于您忘记将类别设置为活动状态的事实

$category->active = 1;

此外,您应该检查$category->save();的返回值。

我希望这会有所帮助!

I find the CURE

if($id_category=Db::getInstance()->getValue('SELECT id_category FROM '._DB_PREFIX_.'category WHERE id_category="'.pSQL($categories).'"')){
                    $category->save();
                }
                else{
                    $category->id= $categories;
                    $category->id_category_default=(int)$family->Code;
                    $category->force_id = true;
                    $category->add();
                }
