I recently needed to add in a credit card expiration date year selector, and just wanted to share the code I used to populate the options. As always, please use this as you see fit.
function ExpYear(){
//Get today's Year
$curYear = date("Y");
//Just in case it's needed, get 2 years ago
$sYear = $curYear - 2;
//Now let's add 10 years
$eYear = $curYear + 10;
$ret = '';
//For $1 = 2 years ago, to 10 years from now, increment 1 year and populate our return variable
for($i = $sYear; $i < $eYear; ++$i){
$ret .= '<option value="' . $i . '">' . $i . '</option>';
}
return $ret;
}
