Passer une session d'un component à un autre

Bonsoir j'ai un formulaire d'inscription mais je n'arrive pas à passer au compte personnel de la personne inscrite malgrès que j'ai fait une redirection vers "administration.component.html". Comment je peux ajouter un code php dans ce component parce que je veux ajouter les cordonnées de la personne inscrite dans la page administration
