list populating proplem

Peuplarchie · 06-08-2008, 08:22 PM

Good day to you all,
I'm working of an auto-populated unordered list.
The way it working I have a recursive directory lister that list all folder in an unordered list.

My problem with that script is hat it start the listing by a ul, how can I stopt it to do so ?

PHP Code:


			

function dirlist($dir) 
{     
 
        $dh = opendir($dir); 
        // the trick is creating the appropriate list tags 
        // before and after the loop 
        // however if the folder is empty then there shouldn't
        // be any UL tags. $isleaf keeps track of that
        $isleaf=true;
        while(($file = readdir($dh)) !== false) 
        { 
                if($file == "." || $file == "..") 
                        continue; 
                $filed = $file;
                $file = $dir . "/" . $file;
                if(is_dir($file)) 
                { 
                
                        if ($isleaf) { $isleaf=false; echo "<ul>\r"; }
                        echo "<li><a href=\"http://test.com/test_images.php?folder=$file\" class=\"blue0\">$filed</a></li>\r"; 

                        dirlist($dir."/".$filed);

 
               }
        } 
        if (!$isleaf) echo "</ul>\r"; 


}    
dirlist ("Pictures/Pics/Pic-S");

Thanks for you time !
Take care !

What do you mean? Started by ul? Also, you just need one $file == "." no need for the same with the ..

I meant, if I run the script it will first display an <ul>
I need it to strat with the ;

PHP Code:


			

if ($isleaf) { $isleaf=false; echo "<ul>\r"; } 
                        echo "<li><a href=\"http://test.com/test_images.php?folder=$file\" class=\"blue0\">$filed</a></li>\r";

The <ul> for the first level is already open before in the page.
this piece of code is only for the next level of folder.

So I think i see what your trying to do, you're trying to set $isleaf to false so that the condition will stop, and ul wont show up? correct?

If your page already has an opening <ul> set in the HTML, just remove it, or remove the one from the script where it says echo"<ul>\r";...?
-m

Orc, you are right.
Delayedinsanity, i need the echo"<ul>\r";...is needed for different level.

Peuplarchie · 06-09-2008, 12:24 AM

Orc only on the first level

Yeah, well it doesn't work that way. :P I think you should try this, just woke up so I'm a bit bleh.

PHP Code:


			


<?php



if ( !empty( $file ) ) { echo "<ul>\r"; }





?>
