XMLTHttpRequest.send() is sending blank values to PHP file. I been trying to debug this but had no luck.
What could be going wrong?
I done a php echo testing below, and im always getting value test2 with nothing else.
AJAX
function subCatActivation(i) {
// var selectedBox = document.getElementById("Cat" + i);
var val = "test";
var hr = new XMLHttpRequest();
var url = "parse_receive_select.php";
hr.open("POST", url, true);
hr.setRequestHeader("Content-type", "application/x-www-form-urlendcoded");
hr.onreadystatechange = function () {
if (hr.readyState == 4 && hr.status == 200) {
var return_data = hr.responseText;
//document.getElementById("sub_cat").innerHTML = return_data;
alert(return_data);
}
}
hr.send("v="+val);
}
PHP
if(isset($_POST['v'])){
echo ($_POST['v']. " test1");
}else if($_POST['v'] == ''){
echo ($_POST['v'] . " test2");
}else{
echo ($_POST['v'] . " test3");
}
