List Subdirectories

[LemonInflux]

How do I modificate this code to show subdirectories?

 

<?php
$files = array();
$dir=opendir($f_user);
while(($file = readdir($dir)) !== false)  
{  
if($file !== '.' && $file !== '..' && !is_dir($file))  
{  
	$files[] = $file;  
}  
}  
closedir($dir);
natcasesort($files);
echo "<ul>\n";
for($i=0; $i<count($files); $i++)  
{
if($files[$i] != "index.php")
echo '<li><a href="'. $f_user .'/'. $files[$i] .'">'. $files[$i] .'</a> - <a href=\delete.php?del='. $files[$i] .'>Delete</a></li>';
}
echo "</ul>\n";
?>

 

$f_user is the username of the person (The user's directory is named '$f_user'). I just want to know how to list them above the files. I can link them up and sort the rest, it's just that bit. Any ideas?

Err, something along the lines of:

 

<?php
$files = array();
$dirs = array();
$dir=opendir($f_user);
while(($file = readdir($dir)) !== false)  
{  
if($file !== '.' && $file !== '..')  
{
 	if(!is_dir($file)){ 
		$files[] = $file;  
	}else{
		$dirs[] = $file;
	}
} 

 

You can then proceed to sort the directories as you do the files, and display those above.

didn't work :\

didn't work :\

 

To recieve good information requires good input. What do you mean by "didn't" work? Did you get an error? Are the arrays empty? Ginger left off the closing bracket for the while loop, but that should have been obvious.

EDIT: Not blank, said that wrong >_< I mean the folders weren't listed.

[GingerRobot]

Try:

 

<?php
$files = array();
$dirs = array();
$dir=opendir($f_user);
while(($file = readdir($dir)) !== false)  
{  
if($file !== '.' && $file !== '..')  
{
 	if(!is_dir($f_user.'\\'.$file)){ 
		$files[] = $file;  
	}else{
		$dirs[] = $file;
	}
} 
} 
closedir($dir);
natcasesort($files);
natcasesort($dirs);
foreach($dirs as $v){
array_unshift($files,$v);
}

echo "<ul>\n";
for($i=0; $i<count($files); $i++)  
{
if($files[$i] != "index.php")
echo '<li><a href="'. $f_user .'/'. $files[$i] .'">'. $files[$i] .'</a> - <a href=\delete.php?del='. $files[$i] .'>Delete</a></li>';
}
echo "</ul>\n";
?> 

 

I changed what is passed to the is_dir() function to make it absolute, and added everything in the $dirs array to the beginning of your $files array to make things nice and easy

[LemonInflux]

Yeah, that worked fine. But is there a way I can change the colour?

[LemonInflux]

Sorry, didn't specify. Is there a way to make links to folders a different colour?

[GingerRobot]

Sure. Instead of adding everything in the $dirs array to the beginning of the $files array, it'll probably be easier to cycle through the two separately. You can then echo out differant css classes for directories and for files.

[LemonInflux]

so the same kind of thing as echo '<li><a href="'. $f_user .'/'. $files[$i] .'">'. $files[$i] .'</a> - <a href=\delete.php?del='. $files[$i] .'>Delete</a></li>';, but with directories instead?

[GingerRobot]

Yep.
