[SOLVED] form not POSTing values help pls!

TheStalker · June 12, 2009

ok i have a form that includes some ajax drop down lists. When a country is selected it fills the next drop down list with values from a database.

The problem i have is that only the values from the first drop down list (country) is posted. The ones that are from the drop downs created with the AJAX are not!

I am pretty new to AJAX so go easy on me

here is my code

main.php

<html>
<head>
<script type="text/javascript" src="selectCountry.js"></script>
</head>
<body>

<form action="main2.php" method ="POST">
Country:
<select onchange="showCountry(this.value)" name="country" >
<option value="">Select one</option>
<option value="1">US</option>
<option value="2">UK</option>
<option value ="3">France</option>
</select>

<input type='submit' value='submit'>
</form>

<p id="here">City: <input type='text' name="city"></p>

</form>

</body>
</html>

selectCountry.js

var xmlhttp;

function showCountry(str)
{
xmlhttp=GetXmlHttpObject();
if (xmlhttp==null)
{
	alert ("Your browser does not support HTTP Request!");
	return;
}
var url="getCountry.php";
url=url+"?q="+str;
url=url+"&sid="+Math.random();
xmlhttp.onreadystatechange=stateChanged;
xmlhttp.open("GET",url,true);
xmlhttp.send(null);
}

function stateChanged()
{
if (xmlhttp.readyState==4)
{
	document.getElementById("here").innerHTML=xmlhttp.responseText;
}
else 
{
	document.getElementById("here").innerHTML = '<img src="ajax-loader.gif"> Loading..';
}
}


function GetXmlHttpObject()
{
if (window.XMLHttpRequest)
{
  // code for IE7+, Firefox, Chrome, Opera, Safari
  return new XMLHttpRequest();
}
if (window.ActiveXObject)
{
  // code for IE6, IE5
  return new ActiveXObject("Microsoft.XMLHTTP");
}
return null;
}PHP

getCountry.php

<?php 
$q=$_GET["q"]; 

$con = mysql_connect('localhost', 'root', ''); 
if (!$con) 
  { 
  die('Could not connect: ' . mysql_error()); 
  } 

mysql_select_db("ajax_demo", $con); 

if ($q == 1) 
{ 
    $sql= mysql_query("SELECT * FROM states"); 
     
    echo "State: "; 
    echo "<select name='state'>"; 
            echo "<option value=''>Select one</option>"; 
    while($row = mysql_fetch_array($sql)) 
        { 
            echo "<option value ='1'>".$row['state']."</option>"; 
        }     
        echo "</select>"; 
     

    echo "<p>City: <input type='text'></p>"; 
         
         
} 
else if ($q == 2) 
{ 
    $sql= mysql_query("SELECT * FROM ukTowns"); 
     
    echo "City: "; 
    echo "<select name='city'>"; 
            echo "<option value=''>Select one</option>"; 
    while($row = mysql_fetch_array($sql)) 
        { 
            echo "<option value ='1'>".$row['town']."</option>"; 
        }     
        echo "</select>"; 
     
} 
else if ($q != 1 || $q !=2) 
{ 
    echo "<p>City: <input type='text'></p>"; 
} 



mysql_close($con); 
?>
