This is my scripts.js

function showHint(str)
{
if (str.length==0)
  {
  document.getElementById("txtHint").innerHTML="";
  return;
  }
if (window.XMLHttpRequest)
  {// code for IE7+, Firefox, Chrome, Opera, Safari
  xmlhttp=new XMLHttpRequest();
  }
else
  {// code for IE6, IE5
  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
xmlhttp.onreadystatechange=function()
  {
  if (xmlhttp.readyState==4 && xmlhttp.status==200)
    {
    document.getElementById("txtHint").innerHTML=xmlhttp.responseText;
    }
  }
xmlhttp.open("GET","inputProcess.php?q="+str,true);
xmlhttp.send();
}

This is my HTML

<script type="text/javascript" src="scripts.js"></script>
<form>
  Type your name here : <input type="text" onkeypress="showHint(this.value)" name="name" />
</form>

This is my PHP file

<?php

  $q = $_GET['q'];
$dbc=mysql_connect("localhost","root","") or die (mysql_error());
  mysql_select_db('input_oop') or die (mysql_error());

  $sql = "INSERT INTO users set name = '".$q."'";
  mysql_query($sql) or die (mysql_error());
  ?>

When the text is save in my database it will save 5 times or up.
