I am trying to create a feature on my website that automatically updates the database onchange of the textarea below (which is going to be act as a 'post-it note for reminders'). I am new to ajax, and I was wondering if someone can show me a basic example of how I would make an AJAX call to update my database onChange of the textarea below?
<?php
//Create mysql connect variable
$conn = mysql_connect('samplesource.com', 'example', 'pass');
//kill connection if error occurs
if(!$conn){
die('Error: Unable to connect.' . '<br>' . mysql_error());
}
//connect to mysql database
mysql_select_db("mydb", $conn);
session_start();
$userid = $_SESSION['id'];
$results = ("SELECT * FROM notes WHERE userid='$userid'");
?>
<html>
<head>
<title>practice</title>
<script src="jquery.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$(".sometext").change(function(){
//make ajax call to update database onChange
});
});
</script>
</head>
<body>
<textarea class="note" style="resize:none; width:300px; height:200px;"> </textarea>
</body>
</html>
