Hoe echo ik de gebruikersnaam van de huidige gebruiker die is ingelogd
Ik ben aan het werken met een inlog scriptje en ik wil graag de username retrieven van de huidige ingelogde gebruiker, voor in een ander deel van de website. Hier wil ik een aantal velden weergeven. Wat is hier de beste manier voor?
Kan ik iets van
Code (php)
1
2
2
session_start();
$_SESSION['username'] = $user
$_SESSION['username'] = $user
toevoegen aan mijn inlog script?
En dan via:
Code (php)
1
2
2
session_start();
$_SESSION['username'] = $user
$_SESSION['username'] = $user
De variabele definiëren.
Het huidige inlogscript:

Iemand een idee?
Maar gezien je een framework lijkt te gebruiken, raad ik aan om in de documentatie te kijken hoe die met sessies omgaat.
