Sitzung funktioniert nicht auf mehrdimensionalen Array

Question

Ich habe derzeit eine harte Zeit auf die Aktualisierung meines Codes mit Sitzungen. der fall ist über webcart. Ich bin jetzt am Add-to-Cart-Prozess. Ich möchte Sitzungen verwenden, um das ausgewählte Element vom Benutzer beizubehalten. aber es scheint, dass jedes Mal, wenn ich diese Sitzungen nutze, diese Aktion nicht auftritt. Bitte hilf mir bei diesem Problem. Übrigens, das ist der Code.
