I have created an HTML page and am attempting to use AJAX via JS to echo from a PHP page:
<!DOCTYPE html>
<html lang="en" xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta charset="utf-8" />
<title>User Retrieval</title>
<script type="text/javascript" src="https://ajax.aspnetcdn.com/ajax/jQuery/jquery-3.2.1.min.js"></script>
<script>
function getid(){
var userid = document.getElementById('userid').value;
$.post('Users2.php', {postname:userid},
function(data){$('#results').html(data);});
};
</script>
</head>
<body>
<h1>User Retrieval</h1>
<p>Please enter a user ID:</p>
<input type="text" id="userid" placeholder="Please insert user ID" onkeyup="getid()" />
<div id="results"></div>
</body>
</html>
I have tested the JS and see that userid indeed gets the information from the HTML.
I then wrote the following PHP:
<?php
if (isset ($_POST['postname'])) {
$name = $_POST['postname'];
echo name;
}
else
{
echo "There is a problem with the user id.";
}
?>
However, I am always getting the else echo statement. What am I missing here?
I am using XAMPP for local host checks.
