Urgent help needed with uploading and downloading files from directory!

[jonathan89]

Hi to all, I have a problem with my coding. Whenever I run my php script on a webpage, it turns up a blank page. Its supposed to retrieve the files from the upload folder and display it on the webpage. Can anyone help me check to see what's wrong?

 

 

<?php

 

$folder = $_SERVER['DOCUMENT_ROOT']."upload"; // the folder which you want to open

 

function select_files($dir) {

    global $PHP_SELF;

    $teller = 0;

   

    if ($handle = opendir($dir)) {

        $mydir = "<p>These are the files in the directory:</p>\n";

        $mydir .= "<form name=\"form1\" method=\"post\" action=\"".$PHP_SELF."\">\n";

        $mydir .= "  <select name=\"file_in_folder\">\n";

        $mydir .= "    <option value=\"\" selected>... \n";

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

            $files[] = $file;

        }

        sort($files);

        foreach ($files as $val) {

            if ($val != "." && $val != "..") {

                $mydir .= "    <option value=\"".$val."\">";

                $mydir .= (strlen($val) > 30) ? substr($val, 0, 30)."...\n" : $val."\n";

                $teller++;   

            }

        }

        $mydir .= "  </select>";

        $mydir .= "<input type=\"submit\" name=\"download\" value=\"Download\">";

        $mydir .= "</form>\n";

        closedir($handle);

    }

    if ($teller == 0) {

        echo "No files!";

    } else {

        echo $mydir;

    }

}

if (isset($download)) {

    $fullPath = $folder.$_POST['file_in_folder'];

    if ($fd = fopen ($fullPath, "r")) {

        $fsize = filesize($fullPath);

        $path_parts = pathinfo($fullPath);

        $ext = strtolower($path_parts["extension"]);

        switch ($ext) {

            case "png":

            header("Content-type: image/png");

            header("Content-Disposition: attachment; filename=\"".$path_parts["basename"]."\"");

            break;

            case "zip":

            header("Content-type: application/zip");

            header("Content-Disposition: filename=\"".$path_parts["basename"]."\"");

            break;

            default;

            header("Content-type: application/octet-stream");

            header("Content-Disposition: filename=\"".$path_parts["basename"]."\"");

        }

        header("Content-length: $fsize");

        header("Cache-control: private");

        while(!feof($fd)) {

            $buffer = fread($fd, 2048);

            echo $buffer;

        }

    }

    fclose ($fd);

    exit;

}       

?>

What I meant is that it would retrieve the images url from the directory and display them in hyperlinks. When the user clicks on them, they would be able to download the images.
