Hello,

can anyone help me out.....I need to:

1/ Get sorting of the categories in the faceted search filter by ID. At this moment I assume the sorting is default by NAME.

2/ I need to set up the new category ID for some already existing categories. Should I rename the ID of existing category in the database or is there any other way? 

In advance thanks for your feedback.

It is not possible to sort by category position without major intervention in the module.
Unable to advise or give modified code.
It is an individual adjustment.
The faceted search module is impractical from the ground up.

Hi, I've get to sort categories by position modifing Block and Converter classes, but I can not get the way to override them. Have you the way to do it? Thank you very much

Hi, I've got a solution overriding ProductListingFrontController, adding this code before renderfacets().

Hope it helps somebody, I spend few hours before I got it 

       //Create new facetCollection to override original one
        $newFacetCollection = new FacetCollection();

        //Iterate facet collection looking for category
        $facetCollection = $result->getFacetCollection()->getFacets();
        foreach($facetCollection as $facet){
            if($facet->getType() == 'category'){

                $undOrderedFacets = $facet->getFilters();
                foreach($undOrderedFacets as $index => $value){
                    $category = new Category($value->getValue());
                    $value->position = $category->position;
                }

                //sort set of facets
                usort($undOrderedFacets, [$this, 'sortFiltersByPosition']);
                
                //sorted facets
                $orderedFacets = $undOrderedFacets;

                //create new facet to pas to collection
                $newFacet = new Facet();
                $newFacet->setLabel($facet->getLabel());
                $newFacet->setType($facet->getType());

                foreach($orderedFacets as $filter) {
                    $newFacet->addFilter($filter);
                }

                //Category facet has only 1 property
                $facetProperties = [
                    'filter_show_limit'=> $facet->getProperty('filter_show_limit')
                ];
                
                $newFacet->setProperty('filter_show_limit', $facetProperties['filter_show_limit']);
                
                $newFacet->setMultipleSelectionAllowed($facet->isMultipleSelectionAllowed());
                $newFacet->setWidgetType($facet->getWidgetType());

                $newFacetCollection->addFacet($newFacet);
            }
            else{
                $newFacetCollection->addFacet($facet);
            }
        }
        //Set new factocollection to result to pass to render
        $result->setFacetCollection($newFacetCollection);

Hi @ivo studiogenesis,

Thank you for your solution ! It seems to be exactly what I need (sort sub-category facets by position and not by name).

But I am novice in Prestashop (and php)... I try to insert your code in classes/controller/ProductListingFrontController.php and I don't see any change.

I insert code at the beginnig of protected function renderFacets(ProductSearchResult $result) {

Maybe it is wrong ? 

Can you help me please ? 

Thank you for your help

        }
        //Set new factocollection to result to pass to render
        $result->setFacetCollection($newFacetCollection);

 

Another option would be to modify the  renderFacets function in

/modules/ps_facetedsearch/src/Product/SearchProvider.php

 

Adding something like

Hi @ventura,

thank you for you help.

unfortunately, I don't know  where to insert this code... 

I try :  

public function renderFacets(ProductSearchContext $context, ProductSearchResult $result)
    {
        list($activeFilters, $displayedFacets, $facetsVar) = $this->prepareActiveFiltersForRender($context, $result);

        // No need to render without facets
        if (empty($facetsVar)) {
            return '';
        }

        $this->module->getContext()->smarty->assign(
            [
                'show_quantities' => Configuration::get('PS_LAYERED_SHOW_QTIES'),
                'facets' => $facetsVar,
                'js_enabled' => $this->module->isAjax(),
                'displayedFacets' => $displayedFacets,
                'activeFilters' => $activeFilters,
                'sort_order' => $result->getCurrentSortOrder()->toString(),
                'clear_all_link' => $this->updateQueryString(
                    [
                        'q' => null,
                        'page' => null,
                    ]
                ),
            ]
        );
		
		if ($displayedFacets[0]['type'] == 'category') {
        foreach ($displayedFacets[0]['filters'] as $key => &$facet) {
            $categories = Category::searchByName($idLang, $facet['label'], true);
			$facet['position']=  $categories['position'];
            }
        array_multisort(array_column($displayedFacets[0]['filters'], 'position'), SORT_ASC, $displayedFacets[0]['filters']);
        }

        return $this->module->fetch(
            'module:ps_facetedsearch/views/templates/front/catalog/facets.tpl'
        );
		

    }

==> ERROR  : Attempted to load class "Category" from namespace "PrestaShop\Module\FacetedSearch\Product".

I am so sorry... I never modify php file... :(

I added  

use Category;

Thank you !

But I had the error ==> Notice: Undefined variable: idLang

So I changed like this :  

 $categories = Category::searchByName($idLang, $facet['label'], true);
==>
 $categories = Category::searchByName($facet['label'], true);

Now I have a new error ==> Notice: Undefined index: position

It is exactly what I want...

I use Prestashop v1.7.8.6 and Facets v3.8.0.

I have this error : ContextErrorException : Notice: Undefined property: PrestaShop\PrestaShop\Core\Product\Search\ProductSearchContext::$shop
