redirect and send variable via js
This is tricky..
I have two sites. Site A and site B. On another site (any site) I p开发者_JAVA技巧ost an affiliate link which takes you to site A where I have a script that redirects to site B (so the first link goes to site B after going through site A)
On site A, I have a variable which I'm trying to pass to site B but without putting it in the browser URL, e.g. http://www.siteB.com/?var=blabla
I was advised to try and use js to post the variables to site B. I tried putting this code in site A..
<body onLoad="submit_form();">
<form name="myform" action="http://www.siteb.com" method="POST">
<input type="hidden" name="var" value="blabla">
</form>
<script language="javascript">
<!--
function submit_form()
{
document.myform.submit()
}
-->
</script>
and on site B I tried using GET to get teh variable but nothing shows up
$var = $_GET['var'];
echo $var;
Must I somehow put the js var in header() ? I'm lost..
It's because your form is POST-ing the data, but you're trying to access the data from the $_GET array.
Try this:
$var = $_POST['var'];
echo $var;
$_POST contains data sent via POST, $_GET contains data sent via GET.
