I have put button on my site and want to perform user twitter login there.
When I execute php script directly it gives expected result, but while calling it from html button click, it gives “302 found error” in firebug console.
What is wrong here?
I want to get echo json_encode((object) array(‘id’ => $id, ‘name’ => $name));
in login.php as a json result.
HTML/JS code
<input type = "button" id = "loginTwitter" class = "btn btn-primary" value = "Login | Twitter "/>
function getTwitterVal(clb)
{
var xmlhttp;
if (window.XMLHttpRequest)
{
// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{
// code for IE6, IE5
xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
var result = xmlhttp.responseText;
alert(result);
// var obj = JSON.parse(result);
clb(obj);
}
xmlhttp.open("POST","p3.php",true);
xmlhttp.setRequestHeader("Content-type","application/x-www-form-urlencoded");
xmlhttp.send();
// api_call();
}
$('#loginTwitter').click(function data() {
getTwitterVal(function(obj) {
// alert(obj.name);
});
});
