[SOLVED] double drop down from db

sandbudd · April 21, 2009

Hey guys it works when I manually put it in like the first code but will not when I try to pull from database to populate?

Here is the index html that works.

<html>
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">

<script>
function getXMLHTTP() { //fuction to return the xml http object
      var xmlhttp=false;   
      try{
         xmlhttp=new XMLHttpRequest();
      }
      catch(e)   {      
         try{         
            xmlhttp= new ActiveXObject("Microsoft.XMLHTTP");
         }
         catch(e){
            try{
            xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
            }
            catch(e1){
               xmlhttp=false;
            }
         }
      }
          
      return xmlhttp;
   }
   
   
   
   function getCity(strURL) {      
      
      var req = getXMLHTTP();
      
      if (req) {
         
         req.onreadystatechange = function() {
            if (req.readyState == 4) {
               // only if "OK"
               if (req.status == 200) {                  
                  document.getElementById('citydiv').innerHTML=req.responseText;                  
               } else {
                  alert("There was a problem while using XMLHTTP:\n" + req.statusText);
               }
            }            
         }         
         req.open("GET", strURL, true);
         req.send(null);
      }
            
   }
</script>




</head>

<body>

<form method="post" action="" name="form1">
<table width="60%" border="0" cellspacing="0" cellpadding="0">
  <tr>
    <td width="150">Make</td>
    <td  width="150"><select name="country" onChange="getCity('findcity.php?country='+this.value)">

    <option value="49">Toyota</option>
    <option value="50">Volkswagen</option>
    <option value="51">Volvo</option>
    <option value="52">Yugo</option>

   
      </select></td>
  </tr>
  <tr style="">
    <td>Model</td>
    <td ><div id="citydiv"><select name="city">
   <option>Select Model</option>
        </select></div></td>
  </tr>
  <tr>
    <td> </td>
    <td> </td>
  </tr>
  <tr>
    <td> </td>
    <td> </td>
  </tr>
</table>
</form>
</body>
</html>

Here is the findCity.php

<?php $country=$_REQUEST['country'];
$link = mysql_connect('', '', ''); //changet the configuration in required
if (!$link) {
    die('Could not connect: ' . mysql_error());
}
mysql_select_db('');
$query="select city from city where countryid=$country";
$result=mysql_query($query);

?>
<select name="city">
<option>Select Model</option>
<?php while($row=mysql_fetch_array($result)) { ?>
<option value><?=$row['city']?></option>
<? } ?>
</select>

Okay I changed index to this and it populates the drop down but the second menu does not populate?


<form method="post" action="" name="form1">
<table width="60%" border="0" cellspacing="0" cellpadding="0">
  <tr>
    <td width="150">Country</td>
    <td  width="150"><select name="country" onChange="getCity('findcity.php?country='+this.value)">

<option>Select Country</option>
<?php while($row=mysql_fetch_array($result)) { ?>
<option value><?=$row['country']?></option>
<? } ?>
</select>
</td>
  </tr>
  <tr style="">
    <td>City</td>
    <td ><div id="citydiv"><select name="city">
   <option>Select Model</option>
        </select></div></td>
  </tr>
  <tr>
    <td> </td>
    <td> </td>
  </tr>
  <tr>
    <td> </td>
    <td> </td>
  </tr>
</table>
</form>
