Gastenboek met admin (admin niet beveiligd)

Auteur: Analog - 29 augustus 2005 - 12:01 - Gekeurd door: nemesiskoen - Hits: 7103 - Aantal punten: (0 stemmen)




Een eenvoudig gastenboek met een admin gedeelte om te editen en te deleten.
Het admin gedeelte is verder niet beveiligd dat zou je er nog bij kunnen doen.

(omdat ik het script voor school moest maken is een groot gedeelte van het commentaar in het engels)

Query voor de database:
SQL-query:
CREATE TABLE `guestbook` (
`id` int( 11 ) NOT NULL AUTO_INCREMENT ,
`auteur` text NOT NULL ,
`email` text NOT NULL ,
`message` text NOT NULL ,
`datum` date NOT NULL default '0000-00-00',
UNIQUE KEY `id` ( `id` )
) TYPE = MYISAM ;
