Ajax validation

[ghjk]

I have a web page developed using php and postgres. There I have a page for user administration(add user). If user fill all information and click submit button I want to send those values to ajax file and validate and insert to the DB. I passed value to the ajax file and I want to send validated values to php file to insert to the DB. How can I do that? Plase help me.
This is my php file.

if(isset($_POST['submit'])){
    $array = array('FullName'=>'FullName','Gender'=>'Gender','PhnNo' =>'PhoneNumber',    'Email' =>'EmailAddress',);
    foreach ($array as $key => $val)
    $$key = $_POST[$val];
 
        $pgsql = "insert into \"User\" ( \"Name\" ,  \"Phone\" ,  \"PtntEmail\",\"Gender\" )
VALUES ('$FullName',  '$PhnNo',  '$Email','$Gender');"; 
 echo $pgsql;
    $result = pg_query($dbconn , $pgsql);
    if (!$result) {
         die("Error in SQL query: " . pg_last_error());
     }
 
        echo "Data successfully inserted!";
     }
 
    ?>            <form name="user.php" id="user.php" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>" >
                      <tr>
                    <td height="24" colspan="3" ><!--DWLayoutEmptyCell-->&nbsp;</td>
                </tr>
                  <tr>
                    <td height="24" >Full Name*</td>
                    <td colspan="2"><input type="text" name="FullName"  size="40" ></td>
                  </tr>
 
                  <tr>
                    <td>Gender</td>
                    <td width="69"><input name="Gender" name="Male" type="radio" value="1"/> Male</td>
 
                    <td width="297"  ><input name="Gender" name="Female" type="radio" value="2" />Female&nbsp;</td>
                  </tr>
 
                  <tr>
                    <td>Phone Number*</td>
                    <td colspan="2"><input type="text" name="PhoneNumber" /></td>
                  </tr>
 
                  <tr>
                    <td>Email Address</td>
                    <td colspan="2"><input type="text" name="EmailAddress" /></td>
                  </tr>
 
                  </tr>
 
                  <tr>
                    <td>&nbsp;</td>
                    <td colspan="2" align="right">
 
                <input id="submit" src="submit.jpg" type="image"  alt="submit" height="30"  width="73" onclick="javascrpit:pages(); return false"  />
 
                    <input id="Cancel" src="Cancel.jpg" type="image"  alt="cancel" height="30"  width="73" />    
 

This is ajax page

function GetXmlHttpObject() {
    var request;
    try {
        request=new XMLHttpRequest();
    }
    catch (e) {
        try {
            request=new ActiveXObject("Msxml2.XMLHTTP");
        }
          catch (e) {
            try {
                request=new ActiveXObject("Microsoft.XMLHTTP");
            }
            catch (e) {
                alert("Your browser does not support AJAX!");
                return false;
            }
        }
    } 
    return request;
}
 
 
function pages(){
var FullName =document.getElementById('FullName').value;
 
}

It would be probably better to use the form for places like this if there is going to be a bit of data.

This is one of my ajax functions..

function displayMiningSelectDialog(astID)
{
    miningDialogHttp = getXMLHttp(); 
    if(miningDialogHttp == null)
    {
        alert ("Browser does not support HTTP Requests");
        return;
    }
    var domain = document.domain;
    var url="http://" + domain + "/GAME/PHP/Scan/ScanXMLhttp.php";
    url=url+"?miningDialog=1&astID=" + astID + "&sid="+Math.random();
    miningDialogHttp.open("GET",url,true);
    miningDialogHttp.onreadystatechange=displayMiningSelectDialogResponse;
    miningDialogHttp.send(null);
} 
function displayMiningSelectDialogResponse() 
{ 
    if (miningDialogHttp.readyState==4 || miningDialogHttp.readyState=="complete")
    {
        eval(miningDialogHttp.responseText);
    }
}
