how to list all the files in current directory

ketanco · 01-29-2012, 05:32 PM

i uploaded pictures to a directory and in that directory i will make an index.php file and with this file i want to be able to list all the pictures in this folder clickable so that my friend who lives far from me can click each of them and look at it. how can i do that?

PHP Code:


			
$folderPath = 'whereismyfiles';
$fList = array();
if ($handle = opendir($folderPath)) {
    while (false !== ($file = readdir($handle))) {
        if ($file != "." && substr($file,0,2) != "._" && $file != "..") {
            $fList[] = $file;
        }
    }
    closedir($handle);
}
// this is the files list
sort($fList);
print_r($fList);

thanks, for the 'whereismyfiles' i typed '../mycurrentfoldername' and it listed the file names but how can i make each item in the list a clickable item so that when clicked the picture will open?

PHP Code:


			
// loop through the files and read the functions
$j = count($fList);
for($i = 0; $i < $j; $i++){
     echo '<a href="">'.$fList[$i].'</a><br>';
}

you will need to figure out the href=""

Here's a solution which will just iterate the images for you and make them clickable.

PHP Code:


			
<? function getFileExtension($filename)
{
  $path_info = pathinfo($filename);
  return @$path_info['extension'];
}

 function getFileList($dir)
  {
    // array to hold return value
    $retval = array();

    // add trailing slash if missing
    if(substr($dir, -1) != "/") $dir .= "/";

    // open pointer to directory and read list of files
    $d = @dir($dir) or die("getFileList: Failed opening directory $dir for reading");
    while(false !== ($entry = $d->read())) {
      // skip hidden files
      if($entry[0] == ".") continue;
      if(is_dir("$dir$entry")) {
        $retval[] = array(
          "name" => "$dir$entry/",
          "type" => filetype("$dir$entry"),
          "size" => 0,
          "lastmod" => filemtime("$dir$entry")
        );
      } elseif(is_readable("$dir$entry")) {
        $retval[] = array(
          "name" => "$dir$entry",
          "type" => getFileExtension("$dir$entry"),
          "size" => filesize("$dir$entry"),
          "lastmod" => filemtime("$dir$entry")
        );
      }
    }
    $d->close();

    return $retval;
  }
  $dirlist = getFileList(".");
?>

<html xmlns="http://www.w3.org/1999/xhtml">

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

<blockquote><br />
 // <b>Pictures</b> //<br /><br /><table border="1">

<?PHP
  // output file list as table rows
  foreach($dirlist as $file) {
    if(($file['type'] != 'jpg')||($file['type'] != 'jpeg')||($file['type'] != 'gif')||($file['type'] != 'png')) continue;
    echo "<tr>\n";
    echo "<td><a href=\"{$file['name']}\">",basename($file['name']),"</a></td>\n";
    echo "<td>{$file['size']}</td>\n";
    echo "<td>",date('r', $file['lastmod']),"</td>\n";
    echo "</tr>\n";
  }
?>
</table>
<body>
</body>
</html>

}

you will need to figure out the href=""

ok now it lists the files as clickable links but when i click does not open the pictures. how can i open that picture when i click its link?

The code I posted - copied and pasted into an index file in your pictures folder will do the trick without any fuss.

actually i tried yours too but it only listed the titles of a table and that was it. i copied and pasted your code as it is. what might be wrong?

Woops should have tested that!

Remove the line;

PHP Code:


			
 if(($file['type'] != 'jpg')||($file['type'] != 'jpeg')||($file['type'] != 'gif')||($file['type'] != 'png')) continue;

one more thing... what if i wanted the pictures to display without clicking, as soon as i open the webpage? what part of the code would i change and how? (i know for many pictures it would be a very very slow opening webpage but thats another thing...)

weir-07 · 01-29-2012, 11:09 PM

Make a html document.
Name it index.
Then insert your pictures into that.

You can google how to do that, I'm sure

ketanco · 01-30-2012, 12:45 AM

ok i know how to do that but for that i would have to type all file names one by one... with your method, i dont... what if i want to share 400 photos with my friend... thats whyi asked that

BluePanther · 01-30-2012, 09:14 PM

Coming back to this, just change the a tags to img tags, with the src as $file['name'] OR change the inside of the a tag an img tag, again with $file['name'] as the src.

I can't believe no one has suggested using glob() yet:

PHP Code:


			
$files = glob( './files/*.{jpg,JPG,jpeg,JPEG,gif,GIF,png,PNG}', GLOB_BRACE );

foreach ( $files as $file )
{
    echo '<a href="' . $file . '">', basename( $file ), '</a><br />';
}
