RussianFrage
Ich möchte auf der Kategorieverwaltungsseite eine neue Registerkarte „Kategorieprodukte“ mit einem Produktraster hinzufügen, das dem Standardproduktraster der Kategorie entspricht.
Der einzige Unterschied besteht darin, dass ich dieses Raster benötige, um ausgewählte Produkte in einer benutzerdefinierten Tabelle mit den folgenden Feldern zu speichern:
1.id
2.product_id
3.category_id
4.Position
Dies ermöglicht mir dann, „vorgestellte Produkte“ mit separater Produktbestellung zu haben, wie im folgenden Wireframe gezeigt:
Screenshot der Unterkategorie mit den „empfohlenen Produkten“.
Erste Gedanken
- Erstellen Sie eine benutzerdefinierte Registerkarte ähnlich wie
Mage_Adminhtml_Block_Catalog_Category_Tab_Product
- Erstellen Sie einen Beobachter, um die Kategoriebeziehung zu speichern
catalog_category_save_after
- Rufen Sie Produkt-IDs mit der aktuellen Kategorie-ID aus der benutzerdefinierten Tabelle ab und markieren Sie sie als ausgewählt
Lösung
Überblick
Nachdem ich mir den Kopf zerbrochen hatte, baute ich endlich ein Modul.
Modelle
Es wurde ein Modell erstellt, das das Kategoriemodell erweitert, um eine benutzerdefinierte Entität zu vermeiden.
Beobachter
addCategoryEssentialBlock
Dieser Beobachter fügt unsere Registerkarte „Neue Produkte“ und das serialisierte Raster auf der Kategorieverwaltungsseite hinzu und hört sich die an adminhtml_catalog_category_tabs Ereignis.
saveCategoryEssentialData
Dieser Beobachter speichert die Kategorie-Essential-Produktbeziehung beim Speichern der Kategorie und hört sich die ancatalog_category_save_after Ereignis.

Andere Tipps
Es ist nicht klar, wie Ihre benutzerdefinierte Registerkarte aussehen soll.Sieht es mit dem Category Products identisch aus, dient nur einen anderen Zweck?
Wenn ja, können Ihre anfänglichen Gedanken gut klingen.Erstellen Sie eine neue Klasse für Ihre benutzerdefinierte Registerkarte.Mage_Adminhtml_Block_Catalog_Category_Tabs::_prepareLayout zeigt Ihnen eine Möglichkeit, eine neue Registerkarte hinzuzufügen.Sie werden sehen, dass diese Methode GEFIRTACDICETAGCODE feuert, die ein Beobachter anschließen kann, um eine andere Registerkarte hinzuzufügen. '
Um die benutzerdefinierten Daten zu speichern, denke ich, dass es gut ist, die "Kategorieaktion speichern" umzuschreiben, sodass Sie die geposteten Daten für Ihre benutzerdefinierte Tabelle abfangen und sie entsprechend speichern können.Ich bin nicht sicher, wie Sie die benutzerdefinierten Daten von adminhtml_catalog_category_tabs abrufen würden, wenn Sie sich dafür entscheiden, verschiedene Produkte unter Ihrer benutzerdefinierten Tab vs. catalog_category_save_after-Registerkarte auszuwählen.
Category Products Beobachter wird nur funktionieren, wenn Ihre benutzerdefinierte Registerkarte und der generationspflichtigen> immer die gleichen Produkte haben.
