Dynamic Sitemap

jbezweb · 10-06-2005, 02:41 PM

Hi,

I need to make a dynamic sitemap for a CMS.

All pages are stored in a DB.

I have pulled all info out into these arrays

PageIds - all pages ids
PageNames - all page names
ParentPages - Parent page of corresponding page (id #'s, except 'root' indicating top level page).

(eg. PageIds[0] is a sub page of ParentPages[0], if ParentPages[0] = 'root' then it is the top, 1st, level)

I need it to support an infinate number of levels. My guess is that it needs to be done in a loop but can't seem to figure out how get it to work.

it should look like this:

Root Page
-Sub Page
-Sub Sub Page
-etc

Any help or direction is greatly appreciated.

Here is what I have so far. It worked with the first 5 values but as I added more and it got more complicated it has flaws in it.

Some pointers or direction would be appreciated.

Thanks,

Code:

@ Page Language="C#" Debug="True" %>

<html>
<head>
 <title>Group Test</title>
</head>

<body>
 <script language="C#" runat="server">

  void Page_Load()
  {
   string Html = "";
   string [] PageIds = new string[10]{"1","2","3","4","5","6","7","8","9","10"};
   string [] PageNames = new string[10]{"Homepage","About Me","Articles","Downloads","Contact Me","page6","page7","page8","page9","page10"};
   string [] ParentPages = new string[10]{"root","1","4","root","2","root","root","6","7","7"};
   int i;
   int j;
   int lvl;
   int indent;
   int currentJ;
   string currentPage = "";
   bool finished = false;

   for(i=0;i<PageIds.Length;i++)
   { 
    lvl = 1;
    indent = 0;
    if(ParentPages[i] == "root")
    {
     finished = false;
     Html += "\n\t\t<div style='width:"+indent+"px;float:left'></div>" + PageNames[i] + "<br>";
     currentPage = PageIds[i];

     while(!finished)
     {
      finished = true;

      for(j=0;j<PageIds.Length;j++)
      {
       if(currentPage == ParentPages[j])
       {
        lvl++;
        indent += 20;
        currentJ = j;
        currentPage = PageIds[currentJ];
        Html += "\n\t\t\t<div style='width:"+indent+"px;float:left'></div>" + 
        PageNames[currentJ] + "<br>";
       }
      }

      for(j=0;j<PageIds.Length;j++)
      {
       if(ParentPages[j] == currentPage)
       {
        finished = false;
       }
      }
     }
    }
   }
   Output.Text = Html;
  }

 </script>

 <form runat="server">
  <asp:Label id="Output" runat="server" />
 </form>

</body>
</html>
