Creating Dynamic Structure

[vayumahesh]

Hi,

I want to create a dynamic structure of structures. I wrote the following code
but I am getting errors with that.

I have three entities department, plant and PCP. There are multiple plants for
a PCP specific to a department. PCP-Department-Plant combination is unique.

User selects multiple departments, corresponding PCPs on the form. Here is my
code ....

<cfset deptPlantPCP = StructNew()>

<cfloop list="#form.department#" index="deptId">
<cfset deptPlantPCP.#deptId# = StructNew()> (Getting error with '.' here)
<cfloop list="#form.pcp#" index="pcpId">
<!--- plants Query for plant_num based on PCP and Department --->
<cfloop from="1" to="#plants.recordcount#" index="pCtr">
<cfset deptPlantPCP.#deptId#.#plants.plant_num[pCtr]# = "#pcpId#">
</cfloop>
</cfloop>
</cfloop>

Thanks for your help.

Try using array notation

<!--- not tested --->
<cfset deptPlantPCP[deptId] = StructNew()>

Thanks, that worked.

How to check if a particular element like deptPlantPCP[deptId][plantId] exists ?

For example, the created structure is
deptPlantPCP[2][25] = 111
deptPlantPcp[1][10] = 118

and I want to check if deptPlantPCP[3][22] exists ? If Yes, get the
corresponding value.

Thanks,
vmrao

This should do it...


<cfscript>
deptPlantPCP = StructNew();
deptPlantPcp[1] = StructNew();
deptPlantPcp[2] = StructNew();

deptPlantPCP[2][25] = 111;
deptPlantPcp[1][10] = 118;

if (StructKeyExists(deptPlantPCP, 3) and StructKeyExists(deptPlantPCP[3], 22))
{
writeoutput("yup");
} else {
writeoutput("nope");
}
</cfscript>
