Benutzer laden unterschiedliche css Dateien

[keek]

Hallo PHP Gurus,

hier ist mal wieder ein php Anfänger. Ich habe folgendes vor:

ich habe Cacti (Cacti: The Complete RRDTool-based Graphing Solution) installiert. Das ist ein Webbasierendes Tool zum auslesen von SNMP Traps. Die Webgui wird über eine css Datei formatiert. (main.css)

Ich möchte gerne, das ein Spezieller Benutzer eine andere Main.css läd.
Hintergrund:
Es wird an einem großem Monitor an an der Wand dargestellt. Die schrift größe habe ich in der Main.css geändert. Leider ist die Webkonfiguration für die „normalen“ Benutzer dadurch echt unübersichtlich.

Meine Idee:
Ich lege eine neue main.css an. (bigmain.css) Diese soll dann von dem speziellen Benutzer geladen werden. Dafür habe ich in die Benutzer Tabelle user_auth im mySQL eine neue Spalte hinzugefügt:

ALTER TABLE `user_auth` ADD `bigmain` INT NOT NULL DEFAULT '0'

Wenn der Benutzer den Eintag 1 in der spalte bigmain hat, soll die bigmain.css geladen werden.

So und nun weiß ich nicht weiter In der datei auth_login.php wird der Benutzer authentifiziert.
Benutzername und PW richtig? Wenn ja wird die main.css geladen. Da müsste jetzt eine Abfrage hin, ob der Benutzer in der Spalte bigmain eine 0 oder 1 hat. Bei 0 wird normal weiter gemacht bei 1 die bigmain.css gelade,
Ist das so möglich oder bin ich am Ziel vorbei gerannt?

Hier ist die auth_login.php

Vielen Dank für eure Hilfe

Morgen,

Ist das so möglich oder bin ich am Ziel vorbei gerannt?

eine einfache Frage verdient eine einfache Antwort: Ja, das ist so möglich.

Hallo Hu5eL

Kann leider keinen Firefox verwenden. Da es eine Multimonitor Lösung ist.
Da hängen 8 Monitore an dem einem System. Jeder öffnet eine andere Seite im IE. Leider öffnet der Firefox immer im zuletzt geöffnetem Monitor. Der IE lässt sich da leichter steuern. Aber dies ist ja nicht mein Problem.

Kann mir einer von euch evtl weiterhelfen?

ideen + lösungsansätze gibt's zahlreiche. schau mal per suma: css konstanten variablen.
