Sending parameters with xmlhttprequest
Im trying to send paramaters with xmlhttprequest but I dont know how. I have an html code with a form and where I create the xmlhttprequest objet and a php code where I want to send the parameters of my form and show them. So, the thing is that it show me the Notice: Undefined variable error, as the variables are not correctly sent. Both codes are in my xampp/htdocs folder.
These are the codes:
HTML & JS:
<!DOCTYPE html>
<html lang="en">
<head>
</head>
<body>
<form name="ajax" method="post">
Surname: <input id="surname" type="text" required/>
<br>
<br>
Name: <input id="name" type="text" required />
<br>
<br>
Phone: <input id="phone" type="tel" required/>
<br>
<br>
<input type="submit" value="Send" name="send">
</form>
<script>
var surname=document.getElementById("surname");
var name=document.getElementById("name");
var phone=document.getElementById("phone");
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function (){
if (this.readyState == 4 && this.status==200){
document.write(this.response);
}
};
xhttp.open("GET","http://localhost/htdocs/show.php surname="+surname+"&name="+name+"&phone="+phone,false);
xhttp.send();
</script>
</body>
</html>
PHP called "show.php":
<?php
$surname;
$name;
$phone;
echo $surname."<br>".$name."<br>".$phone;
?>
Thank you in advance
