The JAVASCRIPT code

function sendinginfomation(){      if(window.ActiveXObject){          xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");      }else{          xmlhttp = new XMLHttpRequest();      }      var fullname = document.getElementById('namefull').value;      var user_n = document.getElementById('nameuser').value;      var email = document.getElementById('email').value;      var user_p = document.getElementById('pass').value;      xmlhttp.open("GET",'php/signup.php?w='+fullname+"&n_p="+user_n+"&tv="+email+"&q="+user_p,true);      xmlhttp.onreadystatechange = function(){          if(xmlhttp.readyState ==4){              $("#loader").fadeOut(300);              document.getElementById('AJAXsignup').innerHTML = xmlhttp.responseText;              }      }      xmlhttp.send(null);  }

If you want to send information with the GET method, add the information to the URL:

xhttp.open("GET", "filename.php?fname=value&lname=value", true);  xhttp.send();  

To POST data like an HTML form, add an HTTP header with setRequestHeader(). Specify the data you want to send in the send() method:

xhttp.open("POST", "filename.php", true);  xhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");  xhttp.send("fname=value&lname=value");

Use Jquery ajax for send var to the PHP page.

$.ajax({          type: "GET", (or POST)          url: "code.php",          data: { fullname, user_n, email },          cache: false,          success: function(){        }      });    });

You just need to change your onclick="validate()" to onclick="sendinginfomation();" OR you can call 2 function on click like onclick="sendinginfomation();validate();"

Answer by itssajan for How to send parameter with AJAX(not Jquery AJAX) and receive it with PHP

Assuming that your validate() is working correctly and the sendinginfomation() is called from within the validate() function I made a working copy of your code. I found an error in $("#loader").fadeOut(300); . If you havn't included jQuery you cant call fadeOut(). But if you have already included jQuery there is no need for javascript function, you can use the jQuery ajax itself.

Other than this your code is working fine.
