[SOLVED] Reading directory--multiple sub directory and displaying

~n[EO]n~ · December 20, 2007

Hi ,

I am trying to read directory, multiple sub directory and display the result., but it is not working anyone got a better idea

The main directory is templates, it lists that well

inside templates there are other sub directory (all contains 2-3 directory under them) and inside the last directory there is index.html page. I want to list (only name) that page and give a link to that.

I tried this but it gives error

Warning: readdir(): 2 is not a valid Directory resource in C:\wamp\www\open_template\open_cms.php on line 8

Warning: closedir(): 2 is not a valid Directory resource in C:\wamp\www\open_template\open_cms.php on line 23

<?php
$mydir = "templates";

if ($handle = opendir($mydir)) 
{
    
    while (false !== ($file = readdir($handle))) 
{
        echo "$file <BR>";
	#second step....
	if ($handle2 = opendir($file))
	{
	while (false !== ($file2 = readdir($handle2)))
	{
	echo "   $file <BR>";
	}
	closedir($handle);
	}
	#end of second step...
}

    closedir($handle);
}
?>

Any help

You need to use recursion.

<?php

  function myread($dir) {
    foreaach(scandir($dir) as $file) {
      if (!$file == '.' || !$file == '..') {
        if (is_dir($file)) {
          myread($file);
        } else {
          echo $file;
        }
      }
    }
  }

  myread('templates');

?>

(not tested)

Thanks Thorpe

but it does not display anything , what may be wrong...

littledragon · December 20, 2007

debug by echoing file at is_dir - you need the full path, so recursion gets tricky here. The next directory path would be "$dir/$file".

still does not show... anything else

These were written as tutorials for my site and were never cleaned off, so...

Here's a long winded class way of doing it:

class dirbasic
{
function dirbasic($dir=null)
{
	$this->data = null;

	if($dir != null)
	{
		$this->data = $this->make_dir_struct();
		$this->data = $this->dir_fill($this->data, $dir);
	}
}

function set($dir)
{
	if($dir != null)
	{
		$this->data = $this->make_dir_struct();
		$this->data = $this->dir_fill($this->data, $dir);
	}
}

function dir_fill($data, $dir, $parent='')
{
	$data['name'] = $dir;
	$base = $parent.$dir;
	if(strcmp($base[strlen($base)-1], '/')!=0)
	{
		$base .= '/';
	}

	$dirs=opendir($base);
	while (($e=readdir($dirs))!==false)
	{
		if( (strcmp($e, '.') == 0) || (strcmp($e, "..") == 0) )
		{
			continue;
		}
		elseif(is_dir($base.$e))
		{
			$le = $this->make_dir_struct();
			$le = $this->dir_fill($le, $e, $base);
			$data['dirs'][] = $le;
		}
		else
		{
			$a = stat($base.$e);
			$data['files'][] = array($e, $a[7], $a[9]);	//	name, size, modtime
		}
	}
	sort($data['dirs']);
	sort($data['files']);
	return $data;
}

function make_dir_struct()
{
	return array('name' => '', 'dirs' => array(), 'files' => array());
}

function print_dirs()
{
	if($this->data != null)
	{
		$this->print_dir($this->data);
	}
}

function print_dir($data, $spacer='')
{
	$spacer .= '   ';
	print $spacer."<b>".$data['name']."</b><br>";

	foreach($data['dirs'] as $e)
	{
		$this->print_dir($e, $spacer);
	}

	foreach($data['files'] as $e)
	{
		$size = $e[1];
		print $spacer."   ".$e[0]."   ".$size."   ".date("d/m/Y H:i:s", $e[2])."<br>";
	}
}
}


$dir = "../";

$d = new dirbasic();
$d->set($dir);
$d->print_dirs();

This generates links as well:

<html>
<head>
<style type="text/css">
a:link { color:#414151; font-size: 11px; text-decoration: none; }
a:active { color:#414151; font-size: 11px; text-decoration: none; }
a:visited { color:#414151; font-size: 11px; text-decoration: none; }
a:hover { color:#5555dd; font-size: 11px; text-decoration: none; cursor: pointer;}
</style>
</head>
<body>
<?php
function getdir($base)
{
$f = array();
$d = array();
$dirs=opendir($base);
while (($dir=readdir($dirs))!==false)
{
	if( (strcmp($dir, '.') == 0) || (strcmp($dir, "..") == 0) )
	{
		continue;
	}
	elseif(is_file($base.$dir))
	{
		$f[] = $base.$dir;
	}
	else
	{
		$d[] = $base.$dir;
	}
}
sort($d);
sort($f);
return array_merge($d, $f);
}

function traverseDirTree($base,$fileFunc,$dirFunc=null,$afterDirFunc=null)
{
$dirs = getdir($base);

foreach($dirs as $path)
{
	if (is_file($path))
	{
		if ($fileFunc!==null)
		{
			$fileFunc($path);
		}
	}
	else
	{
		if ($dirFunc!==null)
		{
			$dirFunc($path);
		}

		if (($subdirectory!='.') && ($subdirectory!='..'))
		{
			traverseDirTree($path.'/',$fileFunc,$dirFunc,$afterDirFunc);
		}

		if ($afterDirFunc!==null)
		{
			$afterDirFunc($path);
		}
	}
}
}

function dodir($path)
{
$level=substr_count($path,'/');
for ($i=1;$i<$level;$i++)
{
	echo '   ';
}
echo "<b>".basename($path)."</b><br>";
}

function dofile($path)
{
$level=substr_count($path,'/');
for ($i=1;$i<$level;$i++)
{
	echo '   ';
}
echo "<a href='".$path."' target='dl'>".basename($path)."</a><br>";
}

traverseDirTree('../','dofile','dodir');
?>
</body>
</html>

Have fun...

Ok thanks rarebit, i used the second one but it is showing file structure of C:/

where to change the path

rarebit · December 21, 2007

traverseDirTree('../','dofile','dodir');

Change the first argument... and your OS!

~n[EO]n~ · December 21, 2007

When i keep default (as you gave) it shows

Config.Msi

Documents and Settings

Administrator folders etc...

when i keep

traverseDirTree('/','dofile','dodir');

it shows the same

and keeping blank gives error

traverseDirTree(' ','dofile','dodir');

Warning: readdir(): supplied argument is not a valid Directory resource in C:\wamp\www\open_template\open_cms.php on line 17

BTW, i want to show directory inside the folders not from outside

My folder is this

open_template

-- templates

-- thunder

-- index.html

-- the wild

-- same as above

i want to list the directory inside templates and my OS is Win XP

Thanks

The default wouldshow from the parent directory '../' (that's what that means).

When you pass an empty string you could put this in (see first example),

if(strcmp($base[strlen($base)-1], '/')!=0)
{
$base .= '/';
}

That'll prevent it ever being empty, in case some does pass an empty string.

I've just had a look at my local copy of this and it does put the inner directories in the right places, all sorted (dirs first, with sub files, dirs etc) and lot! So i'm unclear as to your problem. My dirs show as you've shown that you want...

By all means it should work as one would expect?

P.S. The first example returns (holds) a data set which you can print out as you want (basic print inc)

~n[EO]n~ · December 21, 2007

Ok , i got the first one working. Thanks a lot...

One more thing i need to ask, now i got the directory listed as i want like below, i don't want to show that images folder and files inside it , in which part i need to add the code, i am not familiar with class and functions...

thunder
