creating a multidimensional array

[natebaca]

How can I combine two arrays in cfscript to form one multidimensional array?

For example, I have two arrays:

firstarray[1]=fred;
firstarray[2]=jim;

secondarray[1]=joe;
secondarray[2]=sam;

and would like to turn them into one array:
combinedarray[1][1]=fred;
combinedarray[1][2]=jim;
combinedarray[2][1]=joe;
combinedarray[2][2]=sam;

Any help would be greatly appreciated.

Hi,

Try using the ArrayAppend function.

<cfscript>

Firstarray = ArrayNew(1);

Secondarray = ArrayNew(1);

Combinedarray = ArrayNew(2); // even ArrayNew(1) will work

arrayset(Firstarray ,1,2,"jim");

arrayset(Secondarray ,1,2,"fred");

ArrayAppend(Combinedarray ,Firstarray);

ArrayAppend(Combinedarray ,Secondarray);

</cfscript>

<cfdump var="#Combinedarray#">

Thanks,

Vamsee

There are two examples listed below.

Here is an example that loops through the arrays as it builds the new one:

<CFSCRIPT>
arr1 = ARRAYNEW(1);
arr1[1] = "fred";
arr1[2] = "jim";

arr2 = ARRAYNEW(1);
arr2[1] = "joe";
arr2[2] = "sam";

array_name_list = "arr1,arr2";

arr3 = ARRAYNEW(2);
FOR(list_idx = 1; list_idx LTE LISTLEN(array_name_list); list_idx = list_idx + 1){
array_name = LISTGETAT(array_name_list,list_idx);
FOR(arr_idx = 1; arr_idx LTE ARRAYLEN(EVALUATE(array_name)); arr_idx = arr_idx + 1){
arr3[list_idx][arr_idx] = EVALUATE(array_name&"["&arr_idx&"]");
}
}
</CFSCRIPT>

<CFDUMP VAR="#arr3#">


Here is a simpler example that appends the arrays to the new array:

<CFSCRIPT>
arr1 = ARRAYNEW(1);
arr1[1] = "fred";
arr1[2] = "jim";

arr2 = ARRAYNEW(1);
arr2[1] = "joe";
arr2[2] = "sam";

arr3 = ARRAYNEW(2);
tmp = ARRAYAPPEND(arr3,arr1);
tmp = ARRAYAPPEND(arr3,arr2);
</CFSCRIPT>

<CFDUMP VAR="#arr3#">
