zoals ik eerder heb laten blijken ben ik best wel een newb op PHP etc etc... gebied, nou heb ik voor de lol is een shoutbox proberen te maken en die dan ook public te releasen, nou ben ik na een tijd een heel stuk verder gekomen en heb van alles toegevoegd... Hier het script:
De SQL query:
CREATE TABLE shoutbox (
id INT(10) not null AUTO_INCREMENT,
name VARCHAR(20),
message TEXT,
date VARCHAR(15),
ip VARCHAR(15),
PRIMARY KEY(id)
);
Het config.php bestand:
<?php

$dbtable = "shoutbox"; //Database table name.
//Language customization
$shoutname = "ShadowIllusions Shoutbox V0.6"; //The name of the shoutbox.
$nick = "ERROR: Please enter a nickname!"; //If no name is entered this will be the error message.
$comment = "ERROR: Please enter a message!"; //If no message is entered this will be the error message.
$code = "ERROR: Wrong security code!"; //If no security code is entered this will be the error message.
//Security Code customization

$fontsize = "5"; //font size (1 - 5).
$fontcolor = "000000"; //font color (RGB hexcode).
$bgcolor = "FFFFFF"; //background color (RGB hexcode).
$linecolor = "B0B0B0"; //line color (RGB hexcode).
//Other customizations
$date = date("m.d.y H:i"); //Change the date and time format, for more information: http://www.php.net/date.
$maxshouts = "10"; //Max shouts displayed.
//DO NOT CHANGE THINGS BELOW THIS LINE IF YOU HAVE NO PHP KNOWLEDGE!!!

de shoutbox geheel: http://shadow.mygamesonline.org/shouttest/
Mijn vraag is nu: Zien jullie dingen die verbeterd kunnen worden met een voorbeeldje zodat ik mijn PHP skill kan verhogen en zuiverder code kan scripten.
EDIT: BTW die $ip variable heb ik nog niet afgemaakt want ik wil een admin pagina maken voor de shoutbox zodat ik IP's kan bannen...
Bedankt!
