setting a form selection to a php session

[HDFilmMaker2112]

I need help setting a form selection to a php session.

 

I'm generating one of my form dropdown menus dynamically, based on the selection of two other drop down menus. But I need the value selected of the generated drop down menu stored so the value be recalled when one of the two other menus change.

 

See this page:

http://beta.area51entertainment.co/signup

 

Change the birthday setting to what ever you want. You'll see that if you set the Month, Then the Day, then the year, the day resets back to "Day" because the year menus onchange call triggers the menu to regenerate. I some how need the day selected to be stored in a session and reselected once the year or month menu changes (unless the day option selected does fit within the new menu generated. I.E; someone selects the 31, but then selects a month with only 30 days.).

 

It maybe that I'm not doing anything with the ajax response, but since I'm triggering a PHP Session variable do I need to? I can't send the response back to the menu id tag, since that'll wipe out the menu generation AJAX since it uses the same id.

 

Maybe send it back to a hidden div?

 

Here's the current code:

 

Form:

elseif(isset($_GET['signup'])){
session_start();
$_SESSION['register_user']="add";
$year_menu=generateBirthYearMenu(date("Y"));
$day_menu=generateBirthDayMenu(null,null);
$switch="notloggedin";

AJAX call:

function requestObj() {
var xmlhttp;
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
return xmlhttp;
}


var http3 = requestObj();

function sendRequest(day_selected){
    http3.open('get', 'signup_sessionset.php?day_selected='+day_selected, true);
    http3.onreadystatechange = handleResquest;
    http3.send(null);
}

 

Function that generates the menu:

function generateBirthDayMenu($month,$year){
session_start();
$_SESSION['month']=$month;
$_SESSION['year']=$year;
$day_array=array(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28);
$month_array1=array("April", "June", "September", "November");
$month_array2=array("January", "March", "May", "July", "August", "October", "December");

if($month=="February" && ($year % 4) ==0 && (($year % 100) !=0 || ($year % 400) ==0)){
array_push($day_array, "29");
}
elseif(!isset($month)){
array_push($day_array, "29", "30", "31");
}
else{

}

foreach($month_array1 as $month_value){
if($month==$month_value){
array_push($day_array, "29", "30");
}
}

foreach($month_array2 as $month_value){
if($month==$month_value){
array_push($day_array, "29", "30", "31");
}
}

foreach($day_array as $day_item){
$day.='<option value="'.$day_item.'"'; if(isset($_SESSION['birthday_day']) && $_SESSION['birthday_day']==$day_item){ $day.=' selected="selected"'; } $day.='>'.$day_item.'</option>'."\n";
}

return $day;
}

 

 

php page where the session should be set, but is not being set:

<?php
session_start();
if(isset($_GET['day_selected'])){
$_SESSION['birthday_day']=$_GET['day_selected'];
}

echo $_SESSION['birthday_day'];
?>
