Hi,

 

I'm having a tough time combining two separate pieces of code. To summarise, I have an entire folder hierachy which I want to access via a group of dropdown boxes, so there is a box for months, a box for the dates and a box for the year. The code I have found on the internet (and slightly modified with the dates etc.) is this:

 

<html>
<head>
<script language="javascript" type="text/javascript">

		function jumpTo(url)

			{

  					document.location.href=url;
  					
			}

</script>
<script type="text/javascript">
var categories = [];
categories["startList"] = ["January","February","March","April","May","June","July","August","September","October","November","December"]

categories["January"] = ["1","2","3","4","5","6","7","8","9","10","11","12","13","14","15","16","17","18","19","20","21","22","23","24","25","26","27","28","29","30","31"];
categories["February"] = ["1","2","3","4","5","6","7","8","9","10","11","12","13","14","15","16","17","18","19","20","21","22","23","24","25","26","27","28","29"];

categories["28"] = ["2008","2009","2010","2011"];

categories["30"] = ["2008","2009","2010","2011"];
categories["31"] = ["2008","2009","2010","2011"];

var nLists = 3; // number of select lists in the set

function fillSelect(currCat,currList){
var step = Number(currList.name.replace(/\D/g,""));
for (i=step; i<nLists+1; i++) {
document.forms['tripleplay']['List'+i].length = 1;
document.forms['tripleplay']['List'+i].selectedIndex = 0;
}
var nCat = categories[currCat];
for (each in nCat) {
var nOption = document.createElement('option'); 
var nData = document.createTextNode(nCat[each]); 
nOption.setAttribute('value',nCat[each]); 
nOption.appendChild(nData); 
currList.appendChild(nOption); 
} 
}

function getValue(L3, L2, L1) {
alert("Your selection was:- \n" + L1 + "\n" + L2 + "\n" + L3);
}

function init() {
fillSelect('startList',document.forms['tripleplay']['List1'])
}

navigator.appName == "Microsoft Internet Explorer" ? attachEvent('onload', init, false) : addEventListener('load', init, false);	

</script> 
</head>
<body>

<form name="tripleplay" action="">
<select name='List1' onchange="fillSelect(this.value,this.form['List2'])">
<option selected>Make a selection</option>
</select>
 
<select name='List2' onchange="fillSelect(this.value,this.form['List3'])">
<option selected>Make a selection</option>
</select>
 
<select name='List3' onchange="getValue(this.value, this.form['List2'].value, 
this.form['List1'].value)">
<option selected >Make a selection</option>
</select>
</form>
</body>
</html>

 

Then I have some code that displays a folder's contents on screen:

 

<?php
($_POST['tripleplay'])  { 

    
     $link  = "../marketing/2011\February\20";

    if (file_exists($link)) 
    
    {
        if ($handle = opendir($link))

			{ 
    				
    				while (false !== ($file = readdir($handle)))
    				
    					{  
       					
       						if ($file != "." && $file != "..")
       						
       							{  
           							if(!preg_match("/\.pdf$/", $file)) continue;
           							
           								{
           									
           									echo "<a href=\"".$link."/".$file."\">".$file."</a><br>";  
        								
        								}
        								
        						}  
        						
        				}
        				
				echo "<br>"; 
    					
    				closedir($handle);  

			}



    }
    break;
?>

Basically I need for the results of the dropdown boxes to help select the folder. So for the above example, if the dropdown says February 20, 2011, it would display that folders contents. I'm sorry that this is such a mess, but I would be grateful for any help you can give
