CFLib.org – Common Function Library Project

Description:
This function will find the matching keys between two structures and update structure1 values with structure2 values. If structure2 has more keys than structure1 the keys will not be added.

Return Values:
Returns a structure.

Example:

<cfset struct1 = structNew() />
<cfset struct1['FNAME'] = "John" />
<cfset struct1['LNAME'] = "Smith" />
<cfset struct1['PHONE'] = "305.555.5555" />

<cfset struct2 = structNew() />
<cfset struct2['FNAME'] = "Bill" />
<cfset struct2['LNAME'] = "Gates" />

<cfdump var="#struct1#" label="Struct 1">
<cfdump var="#struct2#" label="Struct 2">

<cfset structUpdateVals(struct1, struct2) />
<cfdump var="#struct1#" label="Updated Struct 1">

Parameters:
