Problem mit einem Upload/Datei anzeige script

rexini · 21 Juni 2008

Hallo,
ich habe ein Problem bzw. mehr eine Frage.

Könnte mir jemand dieses Script so erweitern das man nur .PNG Datei hochladen kann?

Ich bin nämlich nicht so besonders gut in PHP.

PHP:

<?
error_reporting(0);
if(!function_exists('imagecreatetruecolor')) $showthumbnails = false;
$leadon = $startdir;
if($leadon=='.') $leadon = '';
if((substr($leadon, -1, 1)!='/') && $leadon!='') $leadon = $leadon . '/';
$startdir = $leadon;

if($_GET['dir']) {
    //check this is okay.
    
    if(substr($_GET['dir'], -1, 1)!='/') {
        $_GET['dir'] = $_GET['dir'] . '/';
    }
    
    $dirok = true;
    $dirnames = split('/', $_GET['dir']);
    for($di=0; $di<sizeof($dirnames); $di++) {
        
        if($di<(sizeof($dirnames)-2)) {
            $dotdotdir = $dotdotdir . $dirnames[$di] . '/';
        }
        
        if($dirnames[$di] == '..') {
            $dirok = false;
        }
    }
    
    if(substr($_GET['dir'], 0, 1)=='/') {
        $dirok = false;
    }
    
    if($dirok) {
         $leadon = $leadon . $_GET['dir'];
    }
}

if($_GET['download'] && $forcedownloads) {
    $file = str_replace('/', '', $_GET['download']);
    $file = str_replace('..', '', $file);

    if(file_exists($leadon . $file)) {
        header("Content-type: application/x-download");
        header("Content-Length: ".filesize($leadon . $file)); 
        header('Content-Disposition: attachment; filename="'.$file.'"');
        readfile($leadon . $file);
        die();
    }
}

if($allowuploads && $_FILES['file']) {
    $upload = true;
    if(!$overwrite) {
        if(file_exists($leadon.$_FILES['file']['name'])) {
            $upload = false;
        }
    }
    
    if($upload) {
        move_uploaded_file($_FILES['file']['tmp_name'], $leadon . $_FILES['file']['name']);
    }
}

$opendir = $leadon;
if(!$leadon) $opendir = '.';

    $opendir = '.';

}

clearstatcache();

    while (false !== ($file = readdir($handle))) { 
        //first see if this file is required in the listing
        if ($file == "." || $file == "..")  continue;
        $discard = false;
        for($hi=0;$hi<sizeof($hide);$hi++) {
