Betreff: [OpenLayers-Users] Need Help with OpenLayers.Request
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;
}
?>
