Problema con immagini

**Littefrido** · 21-03-2012, 10:46

Buongiorno, intanto vi dico subito che sono nuovo sia del forum che di PHP .
Il mio problema è questo.
Sgto provando a ridimensionare un'immagine con quesro script.

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>



<head>

<title>Image Uploading!</title>

</head>
<body>

<?php

// Check for the POST
if( !isset( $_POST['p'] ) ){ $_POST['p']=0; }

if( $_POST['p'] == 1 ){
include( 'includes/uploadimage.php' );
}else{
include( 'includes/uploadform.php' );
}

?>

</body>

</html>

Che richiama altri 2 file nella cartella includes.
L'upload sembra lo fa ma quando arriva al 100% mi daq questo errore.

Warning: imagejpeg(): Unable to open 'uploads/thumb_8735316fb2d0716063b483964a9b4e27.jpg' for writing: No such file or directory in /web/htdocs/www.vendoecerco.it/home/includes/uploadimage.php on line 104 Warning: move_uploaded_file(uploads/8735316fb2d0716063b483964a9b4e27.jpg): failed to open stream: No such file or directory in /web/htdocs/www.vendoecerco.it/home/includes/uploadimage.php on line 131 Warning: move_uploaded_file(): Unable to move '/tmp/php4m4WsV' to 'uploads/8735316fb2d0716063b483964a9b4e27.jpg' in /web/htdocs/www.vendoecerco.it/home/includes/uploadimage.php on line 131 You've just uploaded a new picture. This is the given data!

Name: 8735316fb2d0716063b483964a9b4e27.jpg

Height: 1224

Ciao, come da warning

No such file or directory in /web/htdocs/www.vendoecerco.it/home/includes/uploadimage.php on line 104

il problema è della pagina uploadimage.php. Posta il codice così da capire dov'è l'errore.

il modo in cui esegui l'upload e il resize delle img è molto approssimativo e poco "controllato".

Studiati questo script/tutorial:
http://net.tutsplus.com/tutorials/ph...easy-with-php/
oppure:
http://www.verot.net/php_class_upload.htm

giusto per citarne alcuni...

-----------------
Da uno sguardo superficiale dello script sono quasi certo che l'errore dipenda da un errata indicazione del path in cui salvare il file specificato in questi righi:

Codice PHP:


$path= 'uploads/' . $upload . $ext;

$thumb_path= 'uploads/thumb_' . $upload . $ext;
