Subdirectories with links

[dmirsch]

In the MySQL help forum someone asked how to list out all the files in a directory. Another person gave the following code:

<?php

$handle = opendir('PUT NAME OF YOUR DIR HERE');
while (false !== ($file = readdir($handle)))
{
    if ($file != "." && $file != "..")
{
        echo $file,'<br />';
    }
}
closedir($handle);
?>

 

I found this to be very helpful! However, is there a way to modify it so that if there are subdirectories, it will list those as hyperlinks so the code would run off of the subdirectory if you were to click that link?

 

When I asked that question in the MySQL forum, I was told that it had nothing to do with PHP which I know. So that's why I am posting it here. Can anyone help?

$path = '/path/to/your/folder/';

$handle = opendir($path);

while (false !== ($file = readdir($handle)))

{

    if ($file != "." && $file != "..")

    {

        if( is_dir($path.$file) )

        echo '<a href="/'.$file.'">'.$file.'</a>';

        else

        echo $file;

        echo '<br>';

    }

}

closedir($handle);

So I used xyph's code and it is not reading anything as a directory. Here's how I modified the code:

<?php

$path = '../../images';
$handle = opendir($path);
while (false !== ($file = readdir($handle)))
{
    if ($file != "." && $file != "..")
    {
        if( is_dir($path.$file) )
           echo '<a href="'.$path.$file.'">'.$file.'</a> is a directory';
        else
           echo $file.' is not a directory';
        echo '<br>';
    }
}
closedir($handle);
?>

 

The sample page is here: http://acpacenterstage.com/centerstage/centertix-managers/reading-files-in-folder.php

As you can see, nothing is reading as a directory even though all but the last two are directories.

 

Any ideas?

Try echo'ing $path.$file

 

$path needs a trailing slash, like my example.

[dmirsch]

Close, I had to add a forward slash to make it really go to the directory.

 echo '<a href="'.$path.$file.'/">'.$file.'</a> is a directory';

 

However, I would like the code to rerun with that new directory once the hyperlink is clicked, because now it tells me,

Access Forbidden

Access denied. Please click on the back button to return to the former page.

since there is no real file name listed in the hyperlink.

 

So somehow if I'd like the coding to keep cycling through until it see no more subdirectories. Is that possible?

[jcbones]

From my library.

 

Make sure you don't close the directory with a slash.

 

ex.

full/path/to/directory/ <-wrong
full/path/to/directory <-right

 

<?php
function dirContents($dir) {
if (is_dir($dir)) {	
	if ($dh = opendir($dir)) {			
		while (($file = readdir($dh)) !== false) {
			if(in_array($file,array('.','..'))) { continue; }
			if(is_dir($dir.'/'.$file)) {					
				$contents[$dir.'/'.$file] = dirContents($dir.'/'.$file);
			} else {
				$contents[] = $dir . '/' . $file;
			}
		}			
		closedir($dh);
	}
}
return $contents;
}

function processArray($array) {
if(is_array($array)) {
	echo '<ol>';
	foreach($array as $key => $value) {
		if(is_int($key)) {
			echo '<li><a href="'.$value.'">'.str_replace('/','',strstr(strrchr($value,'/'),'.',true)).'</a></li>';
		}
		else {
			echo '<li><span style="font-weight:bold">' . $key . '</span>';
			processArray($value);
			echo '</li>';
		}
	}
	echo '</ol>';
}
}

processArray(dirContents('PATH TO DIRECTORY'));
?>

[dmirsch]

This is almost there. It gives me the following error though:

Warning: Wrong parameter count for strstr() in /data/23/2/100/53/2263053/user/2487001/htdocs/centerstage/centertix-managers/reading-files-in-folder.php on line 42

Here's the code that goes on line 42:

echo '<li><a href="'.$value.'">'.str_replace('/','',strstr(strrchr($value,'/'),'.',true)).'</a></li>';

[jcbones]

Yes, the optional parameter to strstr() is available only on PHP 5.3.0 and later versions.  Hold on a sec, and I will get a work around to that.

[jcbones]

Replace that line with these two lines.

$name = strrchr($value,'/');
echo '<li><a href="'.$value.'">'.substr($name,1).'</a></li>';

[dmirsch]

Thanks jcbones! This works. Last thing though, there are a bunch of .LCK files on the server that I do not want to show up in the list. If there an easy way to edit the coding to make those a no-show?

 

Here's the code once again:

<?php
function dirContents($dir) {
if (is_dir($dir)) {	
	if ($dh = opendir($dir)) {			
		while (($file = readdir($dh)) !== false) {
			if(in_array($file,array('.','..'))) { continue; }
			if(is_dir($dir.'/'.$file)) {					
				$contents[$dir.'/'.$file] = dirContents($dir.'/'.$file);
			} else {
				$contents[] = $dir . '/' . $file;
			}
		}			
		closedir($dh);
	}
}
return $contents;
}

function processArray($array) {
if(is_array($array)) {
	echo '<ol>';
	foreach($array as $key => $value) {
		if(is_int($key)) {
			$name = strrchr($value,'/');
			echo '<li><a href="'.$value.'">'.substr($name,1).'</a></li>';
		}
		else {
			echo '<li><span style="font-weight:bold">' . $key . '</span>';
			processArray($value);
			echo '</li>';
		}
	}
	echo '</ol>';
}
}

processArray(dirContents('../../images'));
?>

[jcbones]

Change:

if(in_array($file,array('.','..'))) { continue; }

 

To:

if(in_array($file,array('.','..')) || strrchr($file,'.') == '.LCK') { continue; }

 

This is un-tested, so let me know how it goes.

[dmirsch]

Yeah! This worked. Thanks so much!

Hi everyone,
I've stumbled across this script a while ago (and it's working fine, thanks btw)
However, I noticed that the order of the files listed seems to be random. How can I change the script to make it list the files alphabetically?
