Imagemagick Thumbnails

Hallo,

Ich versuche gerade etwas zu Coden. Es geht um einen Remote-Image Upload und der Thumbnail funktion von imagemagick.

So soll es laufen:
-> Kopiere Bild von URL (funktioniert)
-> Eintragen in DB (funktioniert ist aber ausgeklammert)
-> Thumbnails erstellen

Ich habe auch ein normales Upload-Script ebenfalls mit der Thumb funktion und das Funktioniert !

Hier der Code:

index.php
Code: 
<?php
include('connect_database.php');
    $url = $_POST["url"];
    echo "<div id='abuse_content'>";
    if($url)
    {
    $file = fopen($url,"rb");
    if($file)
    {
    $directory = "./file/"; // Directory to upload files to.
    $valid_exts = array("jpg","jpeg","gif","png"); // default image only extensions
    $ext = end(explode(".",strtolower(basename($url))));
    
    if(in_array($ext,$valid_exts)){
    $rand = rand(10000,99999);
    $filename = $rand . basename($url);
    $newfile = fopen($directory . $filename, "wb"); // creating new file on local server


    if($newfile)
    {
    while(!feof($file))
    {
    // Write the url file to the directory.
    fwrite($newfile,fread($file,1024 * 8),1024 * 8); // write the file to the new directory at a rate of 8kb/sec. until we reach the end.
    }
    
    include('uploader_url_thumb.php');
    
    $newfilename = "file/$filename";
    $key = mt_rand(99999,999999);
    $img = getimagesize($newfilename);
    $width = $img[0];
    $height = $img[1];
    $extension = "no";
    $date = date('Y-d-m');
    $size = "10";


    // schreibe in die datenbank mysql_real_escape_string ist empfehlenswert um seine daten gegen sql injections abzusichern 
    $sql_befehl = mysql_query("INSERT INTO file (fileid, filename, filesize, extension, date, width, height, secretkey) VALUES ('', '".mysql_real_escape_string($filename)."', '".mysql_real_escape_string($size)."', '".mysql_real_escape_string($extension)."', '".mysql_real_escape_string($date)."', '".mysql_real_escape_string($width)."', '".mysql_real_escape_string($height)."', '".mysql_real_escape_string($key)."')");
    $lastid = mysql_insert_id();


    echo"<div id='getdetails'>";
    
    //Output small thumb
    echo "

    "; 
    
     echo "

    } else { echo 'Could not establish new file ('.$downloads.$rand.basename($url).') on local server. Be sure to CHMOD your directory to 777.'; }

config.php
Code: 
$config = array(
  'upload_path' => 'file/', // This is a directory to save our images
  'thumbnail_path' => 'file/thumbs/', // This is a directory to save our thumbnails
  'max_width' => 150, // Width of our thumbnail
  'max_height' => 150, // Height of our thumbnail
  'imagemagick_path' => '/usr/bin/' // The path to 'convert' or 'convert.exe'
 );

Leider bekomme ich das bild nicht ausgegeben...
im src steht nur <img src="Resource id #7"> ...
Was ist denn falsch ?

Danke

Die URL ist übrigens HTML5 Layout

EDIT: Nun habe ich zwar eine Ressource aber ich bekomme diese Fehlermeldung.

convert: missing an image filename `file/thumbs/' @ error/convert.c/ConvertImageCommand/2940. Less sucess! Could not make a thumbnail, but we did upload your file!

Da kann man eigentlich nur drüber fliegen.
Keiner weiss mehr, welches File(Script) du nun verwendest und welches nicht. Original interessiert nicht, nur dass Script, dass du wirklich verwendest.
Schön wäre, wenn du auch die entsprechenden Codebuttons verwenden würdest.

Soweit ich das sehe, fehlt der Dateipfad. Du arbeitest in deinem Uploadscript mit $filename
PHP: 
$newfilename = "file/$filename";
das Thumbscript aber mit $filepath
PHP: 
@getimagesize($filepath))
ein
PHP: 
print_r($filepath);
in deinem Thumbscript würde wahrscheinlich zeigen, dass es keine Datei gibt die man zu einem Thumb machen könnte.

In deinem Thumbscript könntest du den Pfad anpassen und aus:
PHP: 
$filepath = $config['upload_path'] . basename($_FILES['uploadedfile']['name']);
das machen:
PHP: 
$filepath = $newfilename;

Achte darauf, dass $newfilename den gesamten Pfad hat.

PS
die beiden Zeilen müssen natürlich getaiuscht werden, aus:
PHP: 
include('uploader_url_thumb.php');          
$newfilename = "file/$filename";
wird
PHP: 
$newfilename = "file/$filename";
include('uploader_url_thumb.php');
Noch besser, du rufst dein Thumb-Script nach dem setzen in der Datenbank auf.

Es ist mir immer unbegreiflich, wie es Leute fertigbringen, so viel Code zu produzieren und dann wie der Ochs vorm Berge vor Fehlermeldungen zu stehen.

Das ist irgendwie so, als würde man einen Pfannkuchen machen und dann am Ende nicht wissen, wie man ihn aus der Pfanne auf den Teller bekommt.

Ist nicht böse gemeint, ich verstehe es wirklich nicht.
