Example

<!---------------------------------------------------------------
This example illustrates the use of IsStruct and StructIsEmpty. 
It assumes that you have created and assigned values to the fields of a 
structure named EMPINFO within an include file. Sometimes when
you have included a file that contains variable declarations, you
may not know if a variable is a structure or a scalar value.
This code not only checks to see if EMPINFO is a structure, it
also checks to see if its fields have been assigned values, and
checks for the existence of a particular field. 
----------------------------------------------------------------->
<CFIF IsStruct(EMPINFO)>
    <CFIF StructIsEmpty(EMPINFO)>
        <P>Error. EMPINFO is empty.</P>
    <CFELSE>
        <CFOUTPUT>
         <P>EMPINFO contains #StructCount(EMPINFO)# fields.
        </CFOUTPUT>
        <CFIF StructKeyExists(EMPINFO, phone)>
        <!--------------------------------------------------------
        Use CFQUERY to find out if this is a new number.
        ---------------------------------------------------------->
        </CFIF>
    </CFIF>
<CFELSE>
    <P>Error. EMPINFO is not a structure.</P>
</CFIF>
