Menu Systeem

Een menu systeem, hiemree kan je heel gemakkelijk menuutjes beheren. 

Je kan menuutjes deactiveren, activeren, omhoog en omlaag verplaatsen, naar een andere zone verplaatsen.

Het script heeft 2 menu zones. Ook heb ik niks aan de lay-out gedaan.

Instructies:
-Maak een map in de map waar het bestand menus.php in staat. Noem die map menus.

-Voer de volgende query uit in je DB:
CREATE TABLE `menus` (
`menu_id` INT NOT NULL AUTO_INCREMENT ,
`menu_naam` VARCHAR( 100 ) NOT NULL ,
`menu_order` INT NOT NULL ,
`menu_zone` INT NOT NULL ,
PRIMARY KEY ( `menu_id` )
);

-Verander de variablen in config.php
-om een menu toe te voegen maak je een map in de map menus.
Noem die map naar de titel van jou menu.
In die map die je net hebt gemaakt maak je een PHP bestand aan met precies de zelfde naam als de map.

Ga naar menus.php en activeer hem in de zone die jij wil.

Om de menus uit de DB te halen doe je het volgende:
Voor menus uit zone 1 zet je bijv. in je header dit:
$menus = mysql_query("SELECT * FROM menus WHERE menu_zone=1 ORDER BY menu_order ASC");
while($menuinfo = mysql_fetch_array($menus)) {
if(file_exists("../menus/".$menuinfo['menu_naam']."/".$menuinfo['menu_naam'].".php")) {
include("../menus/".$menuinfo['menu_naam']."/".$menuinfo['menu_naam'].".php");
echo "<br>";
}

voor zone 2, bijv. in je footer:
$menus = mysql_query("SELECT * FROM menus WHERE menu_zone=2 ORDER BY menu_order ASC");
while($menuinfo = mysql_fetch_array($menus)) {
if(file_exists("../menus/".$menuinfo['menu_naam']."/".$menuinfo['menu_naam'].".php")) {
include("../menus/".$menuinfo['menu_naam']."/".$menuinfo['menu_naam'].".php");
echo "<br>";
}

Nou dat het was het denk ik wel, voor vragen/bugs opmerkingen kun je altijd een comment plaatsen
