Help with a date select box

[mikeoffy69]

So I have this program I purchased and it allows me to create custom form fields. I have been trying to create a date select box but have been struggling because I am just learning php. I was wondering if someone could lend a hand.  I will try and give as much info as i can.  First I will show a picture of the custom field box and then i will give the description of both boxes that the company gave me. Next i will give you the php code i have been trying to work with. Please if my code is not the best then i will take any advice. I found the code for the date selector online.

 

 

Parsed Default Value  -  You may specify a variable or a function as the default value; for example $_SERVER[HTTP_USER_AGENT] or mktime()

 

 

Parsed PHP Code -    You can specify actual PHP code that will be used to return a variable. // You should assign the value you wish to use to the variable $str.

 

 

<?PHP

FUNCTION buildDate($name, $m, $d, $y) {
        $date = DATE("m-d-Y",STRTOTIME("now"));
        $date_array = EXPLODE("-",$date);

        $now_d = "";
        $now_y = "";
        $month = '<select class="small" name="'.$name.'_month">';
        $month .= '<option value="" selected disabled>mm</option>';
        FOR ($i=1;$i<=12;$i++) {
                IF ( $m != "" ) {
                        IF ( $m == $i ) {
                                $now_m = "selected";
                        }
                }ELSEIF ( $m == "0" ) {
                        $now_m = "";
