Is this better then?
<form id="form1" name="form1" method="post" action="cart.php">
<input name="size" type="radio" value="Small">Small<br>
<input name="size" type="radio" value="Large">Large<br>
<input name="size" type="radio" value="XXL">XXL<br>
<input type="hidden" name="sizes" id="sizes" value=""/>
<input type="hidden" name="pid" id="pid" value="85" />
<input type="submit" name="button" value="Add To Cart"/></form>
Just a quick note that for retreiving the result I am using this code here:
if(isset($_POST['sizes'])){
$myvar = $_POST['sizes'];
echo "Your Size:", $myvar ;
}
With JavaScript & jQuery:
$("#form1 input[name='size']").click(function(){
var size = $('input:radio[name=size]:checked').val();
$("#form1 input[name='sizes']").val(size);
});
That should do the trick.
You seem to be calling the radio buttons 'form1' but you have the same name for the first hidden field.
I would suggest that the form is submitting this field and ignoring the radio buttons for this reason.
Looking at your revised code, surely you need:
$myvar = $_POST['size'];
if ($myvar) {
echo "Size is $myvar";
}
'sizes' is never getting set to a 'true' value.
Note: the if ($myvar)
works, in this instance, as effectively as the 'isset' statement but is simpler to code and read.
