Listing files in a directory 10 at a time

**jazztie** · Sep 18, 2001 09:54

I have the following script for printing the first 10 files in a directory:

PHP Code:


<?

$handle = opendir('.'); 



print    "<table>

    <tr bgcolor='#CCCCCC'>

      <td>Filename: </td>

      <td>File-size: </td>

    </tr>";



$max = '10';

$min = 0;

        

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

    if ($i >= $min && $i <= $max){

    if ($file != "." && $file != ".." && ereg(".php",$file)) { 

        $file_size = ceil(filesize ($file) / 1024);

            print "<tr>

                <td><a href='$file'>$file</a </td> 

                <td align='right'>$file_size k </td>

                </tr>"; 

    }

    $i++;

    }

    else {

        die();

    } 

}

closedir($handle); 

?>

Which works like a charm. However, what I want is to allow the user to scroll from one page to another when there are more than 10 files in a directory.

So: How do I change the code so that 10 files are shown at a time, printing a [next] button when there are more, showing the next 10 files?

Any help is appreciated

Here is one I wrote a while back that does what you want.

PHP Code:


<html>

<head>

    <title>Untitled</title>

</head>



<body>

<table>

    <tr bgcolor='#CCCCCC'>

      <td>Filename: </td>

      <td>File-size: </td>

    </tr>

<?

$d = dir(".");

$max = 10;

$offset = ($offset) ? $offset : 0;



while($f = $d->read()) {

    if(($f != '.') && ($f != '..') && !is_dir($f)) {

        $files[] = array("name" => $f,

                         "size" => filesize($f)

                         );

        }

    }

$d->close();



if(count($files)) {

    $top = (($offset+$max) > count($files)) ? count($files) : $offset + $max;

    for($i=$offset;$i<$top;$i++) {

        ?>

        <tr>

            <td><?=$files[$i]['name']?></td>

            <td><?=$files[$i]['size']*.001?> kb</td>

        </tr>

        <?

        }

    }

else {

    print "<tr><td colspan=2>No files in this direcotry</td></tr>";

    }



if($offset > 0) {

    ?>

        <tr>

            <td colspan=2 align=right><a href="<?=$PHP_SELF?>?offset=<?=($offset - $max)?>">[prev]</a></td>

        </tr>

    <?

    }

if((count($files) > $max) && (($offset + $max) < count($files))) {

    ?>

        <tr>

            <td colspan=2 align=right><a href="<?=$PHP_SELF?>?offset=<?=($offset + $max)?>">[next]</a></td>

        </tr>

    <?

    }    

    



?>

</table>

</body>

</html>

Thanks Freddy!!

It works like a charm. Just perfect.

I have one more, related question:

$d reads out the current directory. Now if I change it to: dir("./images/"); I get the files from the images-folder.
But somehow, it won't display the size of the images.

Is it possible to use the same file (I called it directoryread.php) for different folders, without having to copy the file into the different folders?

Thanx!

Yes you'll just need to set a var for the folde ryou want to to read then use that var in the filesize() function.

Make these changes

PHP Code:


$d = dir(".");

change to

PHP Code:


$dirToRead = 'beavis/';

$d = dir($dirToRead);

AND

PHP Code:


                     "size" => filesize($f)

change to

PHP Code:


                     "size" => filesize($dirToRead.$f)
