CFML select only 3 int from form.zipcode

Question

I know this is probably easy but how to would I select only the first 3 digits from a form field called zipcode when I do #form.zipcode#

I would prefer this to be in cfml if possible.

Example 03954 becomes 039

This is for doing shipping calculations.

Thanks in advance.

Very easy, use the built-in left() function.

Tags:

<cfset fullZipCode = trim(form.zipcode) />    
<cfset firstThree = left(fullZipCode, 3) />    
<cfdump var="#firstThree#" />

or in cfscript

<cfscript>    
  fullZipCode = trim(form.zipcode);     
  firstThree = left(fullZipCode, 3);     
  writeDump(var="#firstThree#");
</cfscript>
