I need help with an ajax call, but I'm a newbie with ajax and I'm not sure as to how to do it.
I have the following PHP code (phonecall.php):
<?php
$con = mysqli_connect('localhost','root','root','mydb');
if (!$con) {
die('Could not connect: ' . mysqli_error($con));
}
mysqli_select_db($con,"mydb");
$sql="SELECT * FROM incoming_calls";
$result = mysqli_query($con,$sql);
while($row = mysqli_fetch_array($result)) {
$callArray[] = array('phonenumber' => $row['phone_number'], 'id' => $row['phone_login_id']);
print "<div id=\"call\">";
print_r($callArray);
print "</div>"
}
mysqli_close($con);
?>
I want to make a page update in real time automatically anytime something new is posted to the table.
Here is my non-working page:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Phone calls</title>
</head>
<body>
<script language="javascript" type="text/javascript">
<!--
//Browser Support Code
function ajaxFunction() {
var ajaxRequest;
try {
// Opera 8.0+, Firefox, Safari
ajaxRequest = new XMLHttpRequest();
} catch (e) {
// Internet Explorer Browsers
try {
ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try {
ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP");
} catch (e) {
// Something went wrong
alert("Your browser broke!");
return false;
}
}
}
ajaxRequest.onreadystatechange = function(){
var ajaxDisplay = document.getElementById('call');
ajaxDisplay.innerHTML = ajaxRequest.responseText;
}
setInterval(function() { //Broken
ajaxRequest.open(); //Not sure what to put here.
}, 1000);
}
//-->
</script>
</body>
</html>
