Blätterfunktion im Gästebuch

Nightmare · 9 Februar 2007

Ich habe ein onefile opensource Gästebuch für meine Zwecke umgeschrieben, allerdings fehlen mir da noch ein paar Funktionen.

Ich hätte gerne eine Blätterfunktion in diesem Gästebuch. So das automatisch nach 10 Einträgen eine neue Seite entsteht. und wie bekomme ich das hin, das man den Teil zum eintragen per klick einklappen kann???

Würde mich über Antworten freuen.

In Aktion:
http://nightmaresh.ni.funpic.de/test/guestbook.php

Code:

<html>
<body>
<?php


$gbfile = "guestbook.txt";
$thisfile = "guestbook.php";
$dateshow = "d-m-Y - H:i:s";
$username = "demo";
$password = "demo";
$wrongpass = "Not logged in!";
$wrongname = "Not logged in!";
$thankstxt = "<meta http-equiv='refresh' content='3;URL=$thisfile'><p>Thank you for writing in my guestbook!<br>You will be sent back in 3 seconds. If not click <a href='$thisfile'>here</a></p>";
$errornoname = "<meta http-equiv='refresh' content='3;URL=$thisfile'><p>You have to enter a name!<br>You will be sent back in 3 seconds. If not click <a href='$thisfile'>here</a></p>";
$errornomsg = "<meta http-equiv='refresh' content='3;URL=$thisfile'><p>You have to enter a message!<br>You will be sent back in 3 seconds. If not click <a href='$thisfile'>here</a></p>";
$gbedited = "<meta http-equiv='refresh' content='3;URL=$thisfile'><p>Guestbook has been edited!<br>You will be sent back in 3 seconds. If not click <a href='$thisfile'>here</a></p>";

Ich arbeite an dem Style des scriptes noch, also wundert uch nicht, wenn es mit dem Link anders aussieht als im Quellcode

Setzt das ganze erst mal in php-tags.

Jau, das hat mir viel gebracht, doch keimt noch eine kleine Frage in mir...

Mit welchem Php befehl kann ich eine bestimmte Zeile aus einer Datei suchen, die mir der Befehl dann als Variable speichert....

Vielen dank schon mal im voraus^^
