trying to set up a 3D Array...what am i doing wrong??? 1

[GregLanders]

I am trying to set up an array with 3 dimensions and then test it by outputing it with 3 nested loops. Here is my code:


<!--- Initializing an array with 3 dimensions --->
<cfset menuitems = ArrayNew(3)>

<!--- Defining the elements of the array --->
<cfset menuitems[1] = &quot;Fruit,/fruit/index.html&quot;>
<cfset menuitems[1][1] = &quot;Apples,/fruit/apples.html&quot;>
<cfset menuitems[1][1][1] = &quot;Green,/fruit/green_apples.html&quot;>
<cfset menuitems[1][1][2] = &quot;Red,/fruit/red_apples.html&quot;>
<cfset menuitems[1][2] = &quot;Oranges,/fruit/oranges.html&quot;>
<cfset menuitems[1][2][1] = &quot;Little Oranges,/fruit/little_oranges.html&quot;>
<cfset menuitems[1][2][2] = &quot;Big Oranges,/fruit/big_oranges.html&quot;>
<cfset menuitems[1][2][3] = &quot;Round Oranges,/fruit/round_oranges.html&quot;>
<cfset menuitems[1][2][4] = &quot;Navel Oranges,/fruit/navel_oranges.html&quot;>
<cfset menuitems[1][2][5] = &quot;Seedless Oranges,/fruit/seedless_oranges.html&quot;>
<cfset menuitems[1][3] = &quot;Bannanas,/fruit/bannanas.html&quot;>
<cfset menuitems[1][4] = &quot;Exotic Fruits,/fruit/exotic_fruits.html&quot;>
<cfset menuitems[1][4][1] = &quot;Kiwi,/fruit/kiwi.html&quot;>
<cfset menuitems[1][4][2] = &quot;Pineapple,/fruit/pineapple.html&quot;>
<cfset menuitems[1][4][3] = &quot;Mango,/fruit/mango.html&quot;>

<cfset menuitems[2] = &quot;Vegetables,/vegetables/index.html&quot;>
<cfset menuitems[2][1] = &quot;Corn,/vegetables/corn.html&quot;>
<cfset menuitems[2][1][1] = &quot;Popcorn,/vegetables/popcorn.html&quot;>
<cfset menuitems[2][1][2] = &quot;Yellow Corn,/vegetables/yella_corn.html&quot;>
<cfset menuitems[2][2] = &quot;Carrots,/vegetables/carrots.html&quot;>
<cfset menuitems[2][3] = &quot;Peas,/vegetables/peas.html&quot;>

<!--- Testing the array with a set of nested loops --->
<cfloop index = &quot;loop1&quot; from=&quot;1&quot; to = &quot;#ArrayLen(menuitems)#&quot;>
<cfoutput>
[#loop1#][#loop2#][#loop3#]</b>: #menuitems[loop1]#<br>
</cfoutput>
<cfloop index = &quot;loop2&quot; from=&quot;1&quot; to = &quot;#ArrayLen(menuitems[loop1])#&quot;>
<cfoutput>
[#loop1#][#loop2#][#loop3#]</b>: #menuitems[loop1][loop2]#<br>
</cfoutput>
<cfloop index = &quot;loop3&quot; from=&quot;1&quot; to = &quot;#ArrayLen(menuitems[loop1][loop2])#&quot;>
<cfoutput>
[#loop1#][#loop2#][#loop3#]</b>: #menuitems[loop1][loop2][loop3]#<br>
</cfoutput>
</cfloop>
</cfloop>
</cfloop>


Here is the error that am getting:

im not sure, but i hope this to help you..

everytime you asign a value to the array you have to specify every of the dimensions.

An array of three dimensions is like a cube... why are you using a 3-D array? (they are not very useful/common)


Anyway, the first element of your array might be defined like this:


<!--- Defining the elements of the array --->
<cfset menuitems[0][0][0] = &quot;Fruit,/fruit/index.html&quot;>

the second:

<cfset menuitems[0][0][1] = &quot;Apples,/fruit/apples.html&quot;>


and so on, depending on which are your dimensions and the place you want to use.


I think is not very useful to use a 3d array... i suggest use to change it for a 2d. it's easier to control and to set. it is just as an excell table, to say a graphic example... and a 3d is exactly as a cube, every of the faces is a space on the array...

I hope this helps you

I have messed around with this all weekend and have finally achieved the results I have been looking for. Thank you very much for your reply. Here is my final code:

<!--- Initializing an array with 3 dimensions --->
<cfset menuitems = ArrayNew(3)>
<!--- Defining the array elements of the menu --->
<cfset menuitems[1][1][1] = &quot;Fruit,/fruit/index.html&quot;>
	<cfset menuitems[1][2][1] = &quot;Apples,/fruit/apples.html&quot;>
		<cfset menuitems[1][2][2] = &quot;Green,/fruit/green_apples.html&quot;>
		<cfset menuitems[1][2][3] = &quot;Red,/fruit/red_apples.html&quot;>
	<cfset menuitems[1][3][1] = &quot;Oranges,/fruit/oranges.html&quot;>
		<cfset menuitems[1][3][2] = &quot;Little Oranges,/fruit/little_oranges.html&quot;>
		<cfset menuitems[1][3][3] = &quot;Big Oranges,/fruit/big_oranges.html&quot;>
		<cfset menuitems[1][3][4] = &quot;Round Oranges,/fruit/round_oranges.html&quot;>
		<cfset menuitems[1][3][5] = &quot;Navel Oranges,/fruit/navel_oranges.html&quot;>
		<cfset menuitems[1][3][6] = &quot;Seedless Oranges,/fruit/seedless_oranges.html&quot;>
	<cfset menuitems[1][4][1] = &quot;Bannanas,/fruit/bannanas.html&quot;>
	<cfset menuitems[1][5][1] = &quot;Exotic Fruits,/fruit/exotic_fruits.html&quot;>
		<cfset menuitems[1][5][2] = &quot;Kiwi,/fruit/kiwi.html&quot;>
		<cfset menuitems[1][5][3] = &quot;Pineapple,/fruit/pineapple.html&quot;>
		<cfset menuitems[1][5][4] = &quot;Mango,/fruit/mango.html&quot;>

<cfset menuitems[2][1][1] = &quot;Vegetables,/vegetables/index.html&quot;>
	<cfset menuitems[2][2][1] = &quot;Corn,/vegetables/corn.html&quot;>

	<cfset menuitems[2][4][1] = &quot;Peas,/vegetables/peas.html&quot;
