如何添加自定义产品“排序依据"在prestashop中的字段? [英] How can I add a custom product "Sort by" field in prestashop?
问题描述
我是Prestashop的新手，我试图添加一个新的排序方式"字段(默认情况下，您具有:相关性"，名称，从A到Z"，名称，从Z到A"，价格" ，从低到高"，价格，从高到低")
I am new to Prestashop and I am trying to add a new "Sort by" field ( where by default you have: "Relevance" , "Name, A to Z" , "Name, Z to A", "Price, low to high", "Price, high to low" )
如您所知，该功能位于名为以下模块的模块中: "Ps_facetedsearch"，链接此处.
As you guys know, the functionality is located in the module called: "Ps_facetedsearch" , link here.
我尝试过:
- 编辑模块文件可以正常工作，但是如果我想保留功能，就无法升级该模块.
- 覆盖，但似乎无法正常工作，它仍然使用相同的旧模块，而不是覆盖的模块.
所以我的问题是:
- 如何以最优雅/最简单的方式在产品列表(前面)中添加附加的排序依据"字段?我很想听听其他解决此问题的方法.
- 例如，如果您购买了另一个可替代主模块的模块("Ps_facetedsearch"，以便两个替代不会冲突)，您可以在没有替代的情况下做到这一点吗?
任何提示都值得赞赏！
PrestaShop版本: 1.7.4.2
PrestaShop version: 1.7.4.2
为了添加其他排序依据"字段，我需要复制/粘贴Ps_facetedsearch模块中的行:
The lines in the Ps_facetedsearch module that I need to copy/paste in order to add an additional "Sort by" field:
private function getAvailableSortOrders()
{
return [
(new SortOrder('product', 'position', 'asc'))->setLabel(
$this->module->getTranslator()->trans('Relevance', array(), 'Modules.Facetedsearch.Shop')
),
(new SortOrder('product', 'name', 'asc'))->setLabel(
$this->module->getTranslator()->trans('Name, A to Z', array(), 'Shop.Theme.Catalog')
),
(new SortOrder('product', 'name', 'desc'))->setLabel(
$this->module->getTranslator()->trans('Name, Z to A', array(), 'Shop.Theme.Catalog')
),
(new SortOrder('product', 'price', 'asc'))->setLabel(
$this->module->getTranslator()->trans('Price, low to high', array(), 'Shop.Theme.Catalog')
),
(new SortOrder('product', 'price', 'desc'))->setLabel(
$this->module->getTranslator()->trans('Price, high to low', array(), 'Shop.Theme.Catalog')
)
// copy and paste here for another one, but lose the upgradability
// of a module.
];
}
在Ps_FacetedsearchProductSearchProvider.php中找到 (第117-136行)
Found in Ps_FacetedsearchProductSearchProvider.php (lines 117-136)
推荐答案
您可以通过覆盖Ps_Facetedsearch模块来添加按选项排序的自定义排序.
You can add custom sort by option by overriding Ps_Facetedsearch module.
您可以按照以下步骤添加自定义排序.
You can follow below steps to add custom sort by order.
1)在文件夹override/modules/ps_facetedsearch中添加文件ps_facetedsearch.php; (如果不存在，则创建文件夹)以及此文件中的以下代码.
1) Add file ps_facetedsearch.php in folder override/modules/ps_facetedsearch; (create folders if not exists) and below code in this file.
<?php
/**
* @override Ps_Facetedsearch
*/
if (!defined('_PS_VERSION_')) {
exit;
}
require_once implode(DIRECTORY_SEPARATOR, array(
__DIR__, 'src', 'Ps_FacetedsearchProductSearchProvider.php',
));
class Ps_FacetedsearchOverride extends Ps_Facetedsearch
{
public function hookProductSearchProvider($params)
{
$query = $params['query'];
// do something with query,
// e.g. use $query->getIdCategory()
// to choose a template for filters.
// Query is an instance of:
// PrestaShop\PrestaShop\Core\Product\Search\ProductSearchQuery
if ($query->getIdCategory()) {
return new Ps_FacetedsearchProductSearchProviderOverride($this);
} else {
return null;
}
}
}
2)将文件Ps_FacetedsearchProductSearchProvider.php添加到文件夹override/modules/ps_facetedsearch/src中； (如果不存在，则创建文件夹)并在其中添加以下代码.
2) Add file Ps_FacetedsearchProductSearchProvider.php in folder override/modules/ps_facetedsearch/src; (create folders if not exists) and add below code in it.
<?php
require_once implode(DIRECTORY_SEPARATOR, array(
__DIR__, '..', '..', '..', '..', 'modules', 'ps_facetedsearch', 'src', 'Ps_FacetedsearchProductSearchProvider.php',
));
require_once implode(DIRECTORY_SEPARATOR, array(
__DIR__, '..', '..', '..', '..', 'modules', 'ps_facetedsearch', 'src', 'Ps_FacetedsearchFiltersConverter.php',
));
require_once implode(DIRECTORY_SEPARATOR, array(
__DIR__, '..', '..', '..', '..', 'modules', 'ps_facetedsearch', 'src', 'Ps_FacetedsearchFacetsURLSerializer.php',
));
use PrestaShop\PrestaShop\Core\Product\Search\URLFragmentSerializer;
use PrestaShop\PrestaShop\Core\Product\Search\ProductSearchProviderInterface;
use PrestaShop\PrestaShop\Core\Product\Search\ProductSearchContext;
use PrestaShop\PrestaShop\Core\Product\Search\ProductSearchQuery;
use PrestaShop\PrestaShop\Core\Product\Search\ProductSearchResult;
use PrestaShop\PrestaShop\Core\Product\Search\Facet;
use PrestaShop\PrestaShop\Core\Product\Search\FacetCollection;
use PrestaShop\PrestaShop\Core\Product\Search\Filter;
use PrestaShop\PrestaShop\Core\Product\Search\SortOrder;
class Ps_FacetedsearchProductSearchProviderOverride extends Ps_FacetedsearchProductSearchProvider
{
private $module;
public function __construct(Ps_Facetedsearch $module)
{
$this->module = $module;
}
public function runQuery(
ProductSearchContext $context,
ProductSearchQuery $query
) {
$facetedSearch = new Ps_FacetedsearchProductSearchProvider($this->module);
$result = $facetedSearch->runQuery($context, $query);
$sortOrders = $this->getAvailableSortOrders();
foreach ($sortOrders as $sortOrder) {
$result->addAvailableSortOrder($sortOrder);
}
return $result;
}
/**
* New sort order that needs to be appended
*
* @return array
*/
private function getAvailableSortOrders()
{
return [
// add your custom sort by orders here;
];
}
}
3)确保在后端启用了overrides；来自 高级参数>性能
3) Make sure overrides is enabled in backend; from Advance Parameters > Performance
4)要加载，您需要覆盖re-index自动加载，并且需要删除class_index.php文件；从var/cache/dev和var/cache/prod文件夹中删除class_index.php文件.
4) To load you overrides you need to re-index autoloads and to do so you need to delete class_index.php file; delete class_index.php file from var/cache/dev and var/cache/prod folders.
5)检查您的商店；新的自定义排序顺序将被添加.
5) Check you shop; new custom sort order will be added.
