Can somebody explain to me how to pass data to my server side program
using OpenLayers.Request? The following example seems to work, only
there are no variables in the $_POST array. My handler prints only:
result is $_POST variables
But apparently the array is empty. What am I missing here?
Here's some sample code that illustrates the problem:
<!-- test_ajax.html -->
<html>
<head>
<title>AJAX Test</title>
<script src="http://openlayers.org/api/OpenLayers.js";
type="text/javascript"></script>
<script type="text/javascript">
function init() {
var XHR = OpenLayers.Request.POST ({
url: "test_ajax.php",
data: "my data",
params: {var1: 'value 1', var2 : 'value 2'},
headers: { "Content-Type": "text/plain" },
callback: myhandler
});
}
function myhandler(XHR) {
alert("result is " + XHR.responseText);
}
</script>
</head>
<body onload="init();">
<h1>AJAX Test</h1>
</body>
</html>
// ---------------------
// test_ajax.php
<?php
echo "\$_POST variables \n";
foreach($_POST as $key => $value){
echo $key.": ".$value;
}
?>
