listing files in subdirectories.

[pikachu]

I'm fairly new to php and not familiar enough with it to solve this problem on my own.  I'm hoping someone here can help!

 

I have a folder filled with subfolders that contain various pdf files.  It is constantly being updated changed.  I would like my php code to scan the directory and do the following: 1. folder names will become Categories, but are not clickable.  2. pdf files that are contained in each folder are listed along with a link. (underneath the appropriate category)

 

Using google, I found a script that ALMOST does what I want, but it is not exact enough. The folder I would like to scan is a subfolder but the script I found scans the root folder.  How do I tell it to scan ONLY a specific folder and its subfolders?

 

Also, I would not like any php files displayed in the content that is output. I only would like pdf files to be shown.

 

Thanks in advance to anyone who takes the time to read my nonsense. 

 

<?php 
  // grab a full file listing from the current and sub directories and show them as anchored 
//(linked) files. 

  // pull a full file listing - requires the Unix 'find' and 'sort commands.  'find' will retrieve a 
//list of all files from the current directory, 'sort' will sort the listing, and 'explode' will split 
//all files into an array passed into $filelist. 

  $filelist = explode("\n",`find .|sort`); 

  // for each item (file) in the array... 

  for ($count=0;$count<count($filelist);$count++) { 

  // get the filename (including preceding directory, ie: ./software/gth1.0.9.tar.gz) 

  $filename=$filelist[$count]; 

   // if it's not a directory, display linked 

    if (!is_dir($filename)) 
      printf("<a href=\"%s\">%s</a><br>\n",$filename,$filename); 

   // otherwise tell the user it's a "category" 

    else printf("<p>Category: %s<p>\n",$filename); 
  }

how about something like this (not tested):

 

<?php
  $dir = 'path/to/folder/';
  if(!is_dir($dir)) die("Invalid directory");
  $dir = realpath($dir)
  foreach(glob('*',GLOB_ONLYDIR) as $cat){
    $subdir = $dir.'/'.$cat;
    if(!is_dir($subdir)) continue;
    echo "<h2>{$cat}</h2><ul>";
    foreach(glob($subdir.'/*.pdf') as $file)
      echo '<li><a href="'.$subdir.'/'.$file.'">'.$file.'</a></li>';
    echo '</ul>';
  }
?>

Thank you very much for your help! Unfortunately using this code I recieve an error "Parse error: syntax error, unexpected T_FOREACH..."

<?php
  $dir = 'path/to/folder/';
  if(!is_dir($dir)) die("Invalid directory");
  $dir = realpath($dir); //missed a semi-colon
  foreach(glob('*',GLOB_ONLYDIR) as $cat){
    $subdir = $dir.'/'.$cat;
    if(!is_dir($subdir)) continue;
    echo "<h2>{$cat}</h2><ul>";
    foreach(glob($subdir.'/*.pdf') as $file)
      echo '<li><a href="'.$subdir.'/'.$file.'">'.$file.'</a></li>';
    echo '</ul>';
  }
?>

That should work.

      echo '<li><a href="'.$subdir.'/'.$file.'">'.$file.'</a></li>';
    echo '</ul>';
  }
?>

That should work.

it would be totally awesome if it did.  i wish i was smart enough to figure out why it doesnt.  :'(

Any more errors? We need anything like that if we're going to help

[pikachu]

no, no errors.  just no content (blank page).    ???

[conker87]

You have changed the $dir variable to the path to your directory?

[pikachu]

yes, i changed it to the correct path.  I'm not getting any errors at all, in fact i think its even doing something since the page takes a split second to load.  but then... white space.  my heart sinks in despair (melodrama)  :'( :'(

[conker87]

Hmm, check in the source of the output in your browser, is there anything there? If so, post it.

[pikachu]

Theres nothing in the output.  I put the php code in a div tag (to control overflow) and the div is completely empty/blank.

 

I was thinking that maybe the code is stuck looping or something and never finishes...  I was always used to the syntax if(something) then (somethingelse).  or maybe theres some brackets missing?  I feel like beating my face into a wall until it's bloody... Ive been trying to do this (seemingly) simple thing for a few days now.  Maybe it's time to go outside. 

[conker87]

If(something)

      {

              etc

      }

 

Is the syntax, though you dont need to use curly brackets if there's only one line to the if...
