Listing Folders

rpanning

Ok, I don't even know where to start with this one since I'm new to PHP. Here's what I would like to do if anyone can help. PHP would list all the files in a specified folder (if possible only .htm), not subfolders and what not. Then for each file have this code.

<a href="$dir/$filename" target="_blank">$filename</a><br />

Now the filename between link tags (the displayed filename) would not display .htm, just the first part of the file name. Any help with this would be great.

The reason I need this is for anyone to be able to put files into a folder and show up on the page without having to updated that page.

Thanks,
Ryan

They will have to refresh to make the changes. Thats the way PHP works. It is nearly all server side.

FlashAges - Yes I do know that. I'm trying not having to go into the html code to add a new file to the list.

Ok, here's what I have so far.

<?php 
$dir = ".";
if ($handle = opendir($dir)) {
    while (false !== ($file = readdir($handle))) { 
        if ($file != "." && $file != ".." && preg_match ("/.htm/", $file)) { 
            echo "<a href=\"$dir/$file\" target=\"_blank\">$file</a><br />\n"; 
        } 
    }
    closedir($handle); 
}
?>

I started with a snip from php.net's documentation. Its working ok so far, the only thing is that it will list out .htm and .html files. For some reason /.htm^/ doesn't work, I get nothing listed.

The only other thing is getting the file name extracted. Ex: Foo.htm to be just Foo

I don't know how to do this but I'll keep looking.

Thanks for your help,
Ryan

maybe sth like that:

test.php:

<table>
<?///here you specify your path...//////
$path='myfolder;
if ( is_dir($path)){
$handle =opendir($path);
if (isset($handle)) {
 /* Licznik do wierszy. */
$count=0;

/ This is the correct way to loop over the directory. /
while (false !== ($file = readdir($handle))) { 
?>

<tr>
<td width=""><?$count++; if ($count>2) {echo ($count-2);};?></td>
<td width="20"></td>
<td width="">
<?//////////////////////////////////////////////////////////filesystem//////////////////////////////////////?>
<a href ="<?echo $path."/".$file;?>" target="_blank">
<?if ($count>2){?><font color="#FF0000"> <?echo "$file\n";?></font> <?};?></a>
</td>
<td width="" align="right"><? if ($count>2) {echo round((filesize($path."/".$file)/1024))."KB";};?></td>
<td><? if ($count>2) {echo date("F j Y h:i:s A", filemtime($path."/".$file));};//last modified////?></td>
<td width="20"></td>
<td><?if ($count>2) {echo date("F j Y h:i:s A", fileatime($path."/".$file));};///last accessed/////////?></td>
<?///////////////////////////////////////////////////////endoffilesystem//////////////////////////////////////// ?>
</tr>
<?};

closedir($handle);}; };?>

</table>

in $path you specify your folder unfortunatelly it lists subfolders, I don't know how to solve this problem - you can show only this files which have size bigger than 0 KB - but sometimes there are files which have 0 KB:
if (filesize($path."/".$file)==0){sth;}else{sth;};
hope it helps..merry christmas

if you don,t want to display .htm extension you can replace
this line:

echo "$file\n";

with this one:

if ((strrchr($file, '.'))==".htm"){echo (substr($file,0,strlen($file)-4));} else {echo $file;};

I have made mistake in line $path='myfolder; - lost one sign it should be: $path='myfolder';

function getDirList ($dirName) { 
$d = dir($dirName); 
while($entry = $d->read()) { 
if ($entry != "." && $entry != ".." && $entry != "index.php" && $entry != "cfg.php") { 
if (is_dir($dirName."\\".$entry)) { 
getDirList($dirName."\\".$entry); 
} else { 
print($dirName."\\".$entry);
}
}
$d->close(); 
}
getDirList("c:\\test\\");

Question - what is the handle variable in my script at the top? Does it have a value or do I have to give it one? I don't know what that does, same with the file variable. I'm assuming that it is assigned a value automaticaly.

Right now I'm digging through a bunch of documentation taking the best of each. I'll post it soon.

Thanks,

$handle = opendir($dir)

$handle is given the return value of opendir. opendir() returns a resource identified, i.e. an ID to a resource, the resource being a directory in this case.

$file = readdir($handle)

$file is assigned the name of one of the files (including directories) of the directory resource $handle. Since that is in a while loop, readdir will keep returning the next filename.

Ok, I think I have it. Here is what I've got...

<?php 
$folder = ".";
$extension = "htm";

$extsize = strlen($extension)+1;
if ($handle = opendir($folder)) {
  while (false !== ($file = readdir($handle))) {
    if (ereg("\.$extension$",$file)) {
      $filename = (substr($file,0,strlen($file)-$extsize));
      echo "<a href=\"$folder/$file\" target=\"_blank\">$filename</a><br />\n"; 
    }
  }
}
?>

First you would set the folder to list and extenstion of what files to list. Then the extension string length is counted for taking it off later in the script (explained in my second post). Everything works great! If anyone finds something that should be changed let me know.

Now, I was thinking about how this is going to be used and it will also need to be sorted by modification time. If someone could help me incorperate it into this script that would be great.

Thanks,
Ryan

Got it working. The script below will:
1. List Specific Folders
2. List Specific File Extensions
3. Sort By Modification Time
4. Creates A Link To Each Listed Item
5. Replace all underscores with a space Ex: "_" will be " "

<?php
$folder = ".";
$extension = "htm";

$fileArray = array();
$extsize = strlen($extension)+1;
if ($handle = opendir($folder)) {
  while (false !== ($file = readdir($handle))) {
    if (ereg("\.$extension$",$file)) {
      $filename = (substr($file,0,strlen($file)-$extsize));
      $fileArray["$filename"] = filemtime("$folder/$file");
    }
  }
  closedir($handle); 
  arsort($fileArray);
  foreach ($fileArray as $file1 => $time) {
    $file2 = ereg_replace("_", " ", $file1);
    echo "<a href=\"$folder/$file1.$extension\" target=\"_blank\">$file2</a><br />\n";
  }
}
?>

If someone wants the same thing just listed alphabetically use this script:

<?php
$folder = ".";
$extension = "htm";

$extsize = strlen($extension)+1;
if ($handle = opendir($folder)) {
  while (false !== ($file = readdir($handle))) {
    if (ereg("\.$extension$",$file)) {
      $filename = (substr($file,0,strlen($file)-$extsize));
      $filename = ereg_replace("_", " ", $filename);
      echo "<a href=\"$folder/$file\" target=\"_blank\">$filename</a><br />\n";
    }
  }
  closedir($handle); 
}
?>

Hope this can help someone else too. Also, if anyone finds something that should be changed please let me know.
