Uploading file ?

Button - 31/07/2005 18:36

PHP ver gevorderde

hallo iedereen,

ben terug begonne met scripten en heb al direct een vraagje.
ik ben namelijk begonnen met files uploaden.
hier zijn alvast the scripts:

het formulier:

php code - Bekijk de code zonder highlighting - Klap code in

<html>
<head>
<title>Administration- upload new files</title>
</head>
<body>
<h1>Upload new new files</h1>
<form enctype="multipart/form-data" action="upload.php" method="post">
<input type="hidden" name="MAX_FILE_SIZE" value="1000">
Upload this file: <input name="userfile" type="file">
<input type="submit" value=" Verzenden ">
</form>
</body>
</html>

<html>
<head>
<title>Administration- upload new files</title>
</head>
<body>
<h1>Upload new new files</h1>
<form enctype="multipart/form-data" action="upload.php" method="post">
<input type="hidden" name="MAX_FILE_SIZE" value="1000">
Upload this file: <input name="userfile" type="file">
<input type="submit" value=" Verzenden ">
</form>
</body>
</html>

de verwerkingspagina met het tonen van een preview van de pagina:

php code - Bekijk de code zonder highlighting - Klap code in

<html>
<head>
<title>Uploading</title>
</head>
<body>
<h1>Uploading file</h1>
<?

if ($userfile=="none")
{
 echo "Problem: no file uploaded";
 exit;
}

if($userfile_size==0)
{
 echo "Problem: uploaded file is zero length";
 exit;
}

if ($userfile_type != "text/plain")
{
 echo "Problem: file is not plain text";
 exit;
}

if (!is_uploaded_file($userfile))
{
 echo "Problem: possible file upload attack";
 exit;
}

$upfile = "C:\web\Chmod".$userfile_name;

if (!copy($userfile,$upfile)){
 echo "Problem: Could not move file into directory";
 exit;
}

echo "File uploaded succesfully<br><br>";
$fp = fopen($upfile, 'r');
$contents = fread ($fp, filesize ($upfile));
fclose ($fp);

$contents = strip_tags($contents);
$fp = fopen($upfile, "w");
fwrite($fp, $contents);

 echo "Preview of uploaded file contents:<br><hr>";
 echo $contents;
 echo "<br><hr>";
 

 
?>
</body>
</html>

<html>
<head>
<title>Uploading</title>
</head>
<body>
<h1>Uploading file</h1>
<?
 
if ($userfile=="none")
{
 echo "Problem: no file uploaded";
 exit;
}
 
if($userfile_size==0)
{
 echo "Problem: uploaded file is zero length";
 exit;
}
 
if ($userfile_type != "text/plain")
{
 echo "Problem: file is not plain text";
 exit;
}
 
if (!is_uploaded_file($userfile))
{
 echo "Problem: possible file upload attack";
 exit;
}
 
$upfile = "C:\web\Chmod".$userfile_name;
 
if (!copy($userfile,$upfile)){
 echo "Problem: Could not move file into directory";
 exit;
}
 
echo "File uploaded succesfully<br><br>";
$fp = fopen($upfile, 'r');
$contents = fread ($fp, filesize ($upfile));
fclose ($fp);
 
$contents = strip_tags($contents);
$fp = fopen($upfile, "w");
fwrite($fp, $contents);
 
 echo "Preview of uploaded file contents:<br><hr>";
 echo $contents;
 echo "<br><hr>";
 
 
 
?>
</body>
</html>

nu ik heb deze scripts van het boek: Sam PHP and MySQL Web Development.
maar als ik een bestand upload (.doc,.html,.php,...)
dan geeft hij: Problem: uploaded file is zero length
(zie script he, het is een zelfgebouwde foutmelding dus )
maar ik weet niet hoe dat komt! Jullie?
ik probeer een bestand naar mijn eigen webserver te uploaden

ps: het kan zijn dat het een stomme fout is want ik ben nogal 'noobie' op dit gebied (chmod, niet?)

op voorhand bedankt

en proficiat met de clickx number 2 !

Moderator		Zie dit topic en (in mijn reactie) de link naar PHP.net. Je dient superglobals ($_POST, $_FILES etc.) te gebruiken.

PHP ver gevorderde		Zou jij of iemand anders dat dan aub willen aanpassen want ik heb verschillende dingen geprobeerd maar lukt niet...

HTML interesse

Het zou zoiets moeten zijn (ik ben noob):

php code - Bekijk de code zonder highlighting - Klap code in

<html>
<head>
<title>Uploading</title>
</head>
<body>
<h1>Uploading file</h1>
<?



if (empty($_FILES['userfile']['name']))
{
 echo "Problem: no file uploaded";
 exit;
}

if($_FILES['userfile']['size']==0)
{
 echo "Problem: uploaded file is zero length";
 exit;
}

if ($FILES['userfile']['type'] != "text/plain")
{
 echo "Problem: file is not plain text";
 exit;
}

if (!is_uploaded_file($FILES['userfile']))
{
 echo "Problem: possible file upload attack";
 exit;
}

$upfile = "C:\web\Chmod".$_FILES['userfile']['name'];

if (!copy($_FILES['userfile'],$upfile)){
 echo "Problem: Could not move file into directory";
 exit;
}

echo "File uploaded succesfully<br><br>";
$fp = fopen($upfile.'/'.$_FILES['userfile'], 'r');
$contents = fread ($fp, filesize ($upfile.'/'.$_FILES['userfile']));
fclose ($fp);

$contents = strip_tags($contents);
$fp = fopen($upfile, "w");
fwrite($fp, $contents);

 echo "Preview of uploaded file contents:<br><hr>";
 echo $contents;
 echo "<br><hr>";
 

 
?>
</body>
</html>

<html>
<head>
<title>Uploading</title>
</head>
<body>
<h1>Uploading file</h1>
<?
 
 
 
if (empty($_FILES['userfile']['name']))
{
 echo "Problem: no file uploaded";
 exit;
}
 
if($_FILES['userfile']['size']==0)
{
 echo "Problem: uploaded file is zero length";
 exit;
}
 
if ($FILES['userfile']['type'] != "text/plain")
{
 echo "Problem: file is not plain text";
 exit;
}
 
if (!is_uploaded_file($FILES['userfile']))
{
 echo "Problem: possible file upload attack";
 exit;
}
 
$upfile = "C:\web\Chmod".$_FILES['userfile']['name'];
 
if (!copy($_FILES['userfile'],$upfile)){
 echo "Problem: Could not move file into directory";
 exit;
}
 
echo "File uploaded succesfully<br><br>";
$fp = fopen($upfile.'/'.$_FILES['userfile'], 'r');
$contents = fread ($fp, filesize ($upfile.'/'.$_FILES['userfile']));
fclose ($fp);
 
$contents = strip_tags($contents);
$fp = fopen($upfile, "w");
fwrite($fp, $contents);
 
 echo "Preview of uploaded file contents:<br><hr>";
 echo $contents;
 echo "<br><hr>";
 
 
 
?>
</body>
</html>

En ik weet niet precies heo het laatste stuk gaat, maar dit ehlpt je een eindjuh op weg.

</html>

maar die werkt ook niet...

kan miss iemand de code is bij zichzelf ook proberen dat het miss aan mijn server liegt ofzo?
of kan je niet uploaden naar je eigen server?:!:

Thomas - 02/08/2005 11:26
Moderator		Als je PHP.net had gelezen had je kunnen weten dat je move_uploaded_file() dient te gebruiken, niet copy()...

ik heb nu deze code

maar krijg deze fouten:

Warning: move_uploaded_file(C:\web\ChmodC:\WINDOWS\TEMP\php3.tmp): failed to open stream: Invalid argument in c:\web\chmod\upload.php on line 38

Warning: move_uploaded_file(): Unable to move 'C:\WINDOWS\TEMP\php3.tmp' to 'C:\web\ChmodC:\WINDOWS\TEMP\php3.tmp' in c:\web\chmod\upload.php on line 38
Problem: Could not move file into directory

-> die dingen die in het vet staan zijn volgens mij dus te veel aan... maar hoe krijg ik die uit die variable?

edit: miss kunnen jullie iets doen aan de code van dat ventje...

nu ik heb de oplossing voor de vorige fout maar nu krijg ik weer deze fout: Warning: move_uploaded_file(C:\web\Chmod\): failed to open stream: Permission denied in c:\web\chmod\upload.php on line 38

Warning: move_uploaded_file(): Unable to move 'C:\WINDOWS\TEMP\php16.tmp' to 'C:\web\Chmod\' in c:\web\chmod\upload.php on line 38
Problem: Could not move file into directory

volgens mij moet ik de map rechten geven ofzo, niet? indien ja, hoe? indien nee, wat is dan het probleem...?
