I've been studying this for a while
and I'm not sure if I'm going about this the right way because every form I setup according
to examples, it doesn't do what I need.
I need
to setup a form that will:
set session when you
select from dropdown menu
not reload/refresh page (i've read that using AJAX solves this)
submit
and stay on SAME page (confused because most AJAX examples send it
to different process.php page which is supposedly "invisible" but it doesn't "stay" on the same page, it redirects.
Basically, client selects quantity of 1
to 10. If they
select "2"... it does NOT reload the page.. but it DOES set a session[quantity]=2. Should be simple... but do I POST
to same page as form? or POST
to different page
and it somehow redirects?
Also, one test I did it kept pasting my "echo session[quantity]" down the page like 7, 2, 3, 5, etc. etc. each time instead of replacing it.
I would paste code but it's all over the place
and I'm hoping for direction on which methods
to use. Feel I need
to start all over again.
Edit: trying
to add code below but can't seem
to paste it properly.
<? ob_start();?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<?php session_start(); ?>

$(function() {
$(".submit").click(function() {
var gender = $("#gender").val();
var dataString = '&gender=' + gender;
if(gender=='')
{
$('.success').fadeOut(200).hide();
$('.error').fadeOut(200).show();
}
else
{
$.ajax({
type: "POST",
url: "join.php",
data: dataString,
success: function(){

$('.error').fadeOut(200).hide();
}

}
return false;
});
});
</script>
<style type="text/css">
body{
}
.error{
color:#d12f19;
font-size:12px;
}
.success{
color:#006600;
font-size:12px;
}
</style>
</head>
<body id="public">
<div style="height:30px"></div>
<div id="container">
<div style="height:30px"></div>
<form method="post" name="form">
<select id="gender" name="gender">
<option value="">Gender</option>
<option value="male">Male</option>
<option value="female">Female</option>
</select>
<div>
<input type="submit" value="Submit" class="submit"/>
<span class="error" style="display:none"> Please Enter Valid Data</span>
<span class="success" style="display:none"> Your gender is <?php echo $_SESSION['gender'];?></span>
</div>
</form>
<div style="height:20px"></div>
</div><!--container-->
</body>
</html>
<? ob_flush(); ?>
and here is my page where the POST goes called join.php (called that in example so I went with it for now)
<?php
session_start();
if($_POST)
{
$gender = $_POST['gender'];
$_SESSION['gender'] = $gender;
}
else
{ }
?>
