sending data through radio button??

volant

var new_url="";
function goTo ()
{
var pay = document.radio.payment.value;
document.radio.payment.value=pay;
alert("The payment is "+pay);
if ( (new_url != "") && (new_url != null) )
window.location=new_url;
}
</script>

the code is showing the payment that is needed to pay.

then i wish to send the value $pay to the creditcard.php (the second page that is requested)

but the problem is, the payment can be shown in the alert section (i.e. The payment is 100)

but whe i browse to the creditcard.php, the variable is undefined!

What should i do for now ??!! Any solutions?? Or i should do in another way?

Hi,

If there is no reason to use javascript, then avoid it. You can very well submit a form using the submit buttons (They were even made for it!

Variables which are empty in a next page, are usually empty because you try to retreive them in the worng way!

So, unless you have very strong arguments for sticking to the java.. stay away from the javascript here:

<body>
<form method="POST" name="form1" action="../creditcard.php">
<input type=radion name="payment" value="CC"> Pay by Credit Card<br>
<input type=radion name="payment" value="OT"> Pay some other way<br>
<input type=submit value="Pay Now"><input type=reset value="Eehmm wrong choice">
</form>

In creditcard.php:

$paymethod = $_POST[payment];
if ($payment == "cc")
{
some action for creditcard
}

TTT

1)
onClick="new_url='http://www.htmlforums.com'">
??????????

remember that you should mention that this is javascript and also ends with ";"
<input name="button2" type="button" onClick="javascript: goTo();" value="Go">

3)
document.radio.payment.value

=>
document.yourFormName.payment.value

4) actual problem...
function goTo () {
if(document.getElementById('crc').checked || document.getElementById('oth').checked) {
if(document.getElementById('oth').checked) {
var pay = "somevalue";
} else {
var pay = "someOTHERvalue";

}
if ( (new_url != "") && (new_url != null) ) {
window.location.href=new_url+"?pay="+pay;
} else {
void(0);
}
} else {
alert("choose payment method");
void(0);
}
}
....
<input TYPE="radio" NAME="button" onClick="new_url='../creditcard.php'" id="crc">
<input type="radio" name="button" onClick="new_url='http://www.htmlforums.com'" id="oth">
