Current Folder (Links)

[Helios]

I want to have the current folder of the file which people are viewing at the top of the page, like this forum except with folders and not forums. For instance, if someone is in the /reviews/games folder, I want it to say at the top:
Home >> Reviews >> Games where Home and Reviews take you to the folder they specify and games takes you no where. As you go down in directories, the directory you were in becomes linkable and the one you are in is not. How can I do this? If I am being to vague, please let me know.

I think i might have an answer to what you are after. There are two parts to the problem.

1) Determining the directory in which the script is running, this can be done from the php enviroment variables

// get the path info (note i am not sure this is the right env var)
$strFilePath = get_env( PATH_INFO );

2) Deconstructing the directory information and turning it the string and links you are after.

// split the directory into directories (place into an array)
$arrDirectoryList = explode( '/', $strFilePath );

// output the Home Text
echo "Home";

// Get the number of directory levels
$intNoLevels = count( $arrDirectoryList );

// now output the directory information
for ( $intCurrDir = 0; $intCurrDir < $intNoLevels; $intCurrDir++ )
{
// get the directory name
$strCurrentDirectory = $arrDirectoryList[ $intCurrDir ];

  // build the link
  $strLink = '';

  for ( $intCount = 1; $intCount <= $intNoLevels; $intCount++ )
        {
        $strLink .= '../';
        }

  echo " >> ";
  echo <a href="' . $strLink . 'destination.php">';
  echo $strCurrentDirectory . '</a>';
  }

I think this is about all (if there are any problems let me know)

Thanks alot, that is really helpful. While the get_env variable seems to be right (I checked php.net and it had a link to page with a list of all of them and what they do) something seems to be amiss though I do not know enough to know exactly what. At first I got some errors on the line that outputs the links. I fixed these and then it just wouldn't seem to get the right folder or something. I am not exactly sure. Again, thanks for helping me. I really appreciate it.

Best regards,
Helios

Months after I originally posted that, I created a function that does just that:

Note: This is very ugly code. It was all on one line and I separated for the sole purpose of this post.

<?PHP
function page_nav($class){ // $class is the CSS class for your links. Set class as "0" for no CSS class defined.
if($class=="0")
{
$echoc="";
}else{
$echoc=" CLASS=\"$class\"";

// Set thisserver, check to see
// if this is on a subdomain
$thisserver=getenv("SERVER_NAME");
$otserver=str_replace("http://","",$thisserver);
$otserver=str_replace(".redhelix.com","",$otserver);
$otserver=str_replace("/","",$otserver);
if($otserver=="www")
{
unset($otserver);
}else{
$otserver=" ".strtoupper($otserver)." ";
}
echo '<A HREF="http://www.redhelix.com/home.php"'.$echoc.'>Home</A>'; // See below
if($PHP_SELF!=="/home.php") // Change home.php to whatever your home page is
{
print("&raquo; ");
$docself=substr($PHP_SELF, 1);
$explodeself=explode("/",$docself); // Separate $PHP_SELF into folders and files
foreach($explodeself as $loc)
{
$currenturl.="/".$loc;
$noext=str_replace(".php","",$loc);
$noextf=str_replace(".rhx","",$noext);
if(eregi(".php",$loc))
{
if($PHP_SELF=="/index.php")
{
$thisserver="http://".$thisserver;
$noextf=str_replace("index",$otserver."Main",$noextf);
}else{
$noextf=str_replace("index","main",$noextf);
}
print("<A HREF=\"$thisserver"."$currenturl"."$echoc\">".ucfirst($noextf)."</A> ");
}else{
print("<A HREF=\"$thisserver"."$currenturl"."$echoc\">".ucfirst($loc)."</A> <SPAN>&raquo; </SPAN>");
}
}
}
} // END FUNCTION
?>
