CFINPUT Validate date as 1922

I am trying to validate dates. If the person enters a 2 digit year, it accepts it but by default it appears that anything below 30 goes to 2000 and anything 1900 for anything above. How can I validate 26 as 1926 when it assumes I mean 2026? Is there a way to specify a date range? OR how can I force a 4 digit year?

I know I can check after the fact for a future date.

If you would like to validate it on the server you can do something like this ...

<cfset inputYear = REReplace(FORM.year,'[^0-9]','','ALL')>
<cfif Len(inputYear) EQ 4>
    <!--- Code for a correct input --->
    <!--- Let them know they made a mistake --->

But the best bet is to use javascript on your front end like i listed below here ...

<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<title>Experts Exchange - js_vaughan</title>

<script type="text/javascript">

      function isFullYear(form) {
            var f = form.year.value; // Set year to what your field is called
            var re = /^\d{4}$/; // Regular expression to check for 4 digits only
            if (re.test(f)) {
                  return true;
            } else {
                  alert("Please enter a 4-digit year");
                  return false;
// -->



<form name="form_name" action="index.htm" onSubmit="return isFullYear(this);">
      <input type="text" name="year" size="5" maxlength="4">
      <input type="submit" value="Submit Year">

You cannot change the way it is interpreted.  It is acually a system setting not a CF setting.  So your only choice is to force a full year - or manually ask the user which year they mean.  In either case it is much easier (and in the case of the prompt you have no choice) to not use cfinput
