move_uploaded_file doesn't work, no error

问题:

I am running running a script which moves an uploaded file with move_uploaded_file(). I have done this thousands of times but for some reason it's not working. I have confimred the following:

1. <form> using method="post" and correct enctype
2. correct file referenced from form
3. directory has permissions 777
4. all the memory_limit, max_execution_time, etc are set to super high settings to avoid timeouts

Basically, the script below returns with just Your image is too big.. I have also enabled ALL errors to display and still don't get an error. Any ideas?

$time = time();
$target_path = "/absolute/path/to/temp/directory/temp/";

$target_path = $target_path.$time.'.jpg'; 

if(move_uploaded_file($_FILES['image']['tmp_name'], $target_path)) {            

} else{
        $error .= '<li>Your image is too big.</li>';
}

Using 1and1 hosting with the php.ini hack :P

UPDATE 1

I would like to add that response from the script occurs exactly after 60 seconds.

UPDATE 2

We might be getting somewhere with this. Just print_r($_FILES) and this is the result of the array:

Array ( 
    [image] => Array ( 
        [name] => P2120267.JPG 
        [type] => 
        [tmp_name] => 
        [error] => 1 
        [size] => 0 
    ) 
) 

So that leads me to believe that the file isn't be uploaded correctly to the server or something? I have checked and the post form is <form action="" method="post" enctype="multipart/form-data">. So, from what I can tell, the file isn't being uploaded to the server's temp area?

UPDATE 3

Noticed the [error] => 1 in the above array. This is apparently down to the filesize being larger than the upload_max_filesize. However, when i set this as 128M, I get a white screen of death after 60 seconds. The file I'm uploading is 2.5MB

Here is my php.ini file:

register_globals=off
memory_limit = 128M 
max_execution_time=3600 
post_max_size = 128M
upload_max_filesize= 128M 

UPDATE 4

With details above, it appears that I am getting a WSOD, but the image is being upoaded. So, how to stop the WSOD? I can't find any errors related anywhere.

UPDATE 5 - FOUND IT!

Shame on me for not giving you guys all the code. It looks like its to do with this line:

resizeImage($feedBurnerStatsSource, PHOTOMSGDIR.'temp/'.$time.'-tmp.jpg',$width,$height);

In the following code:

function resizeImage($source, $destination = NULL,$wdt, $height = NULL){
    if(empty($height)){
            // Height is nit set so we are keeping the same aspect ratio.
            list($width, $height) = getimagesize($source);
            if($width > $height){
                    $w = $wdt;
                    $h = ($height / $width) * $w;
                    $w = $w;
            }else{
                    $w = $wdt;
                    $h = $w;
                    $w = ($width / $height) * $w;
            }
    }else{
            // Both width and Height are set.
            // this will reshape to the new sizes.
            $w = $wdt;
            $h = $height;
    }
    $source_image = @file_get_contents($source) or die('Could not open'.$source);
    $source_image = @imagecreatefromstring($source_image) or die($source.' is not a valid image');
    $sw = imagesx($source_image);
    $sh = imagesy($source_image);
    $ar = $sw/$sh;
    $tar = $w/$h;
    if($ar >= $tar){
            $x1 = round(($sw - ($sw * ($tar/$ar)))/2);
            $x2 = round($sw * ($tar/$ar));
            $y1 = 0;
            $y2 = $sh;
    }else{
            $x1 = 0;
            $y1 = 0;
            $x2 = $sw;
            $y2 = round($sw/$tar);
    }
    $slate = @imagecreatetruecolor($w, $h) or die('Invalid thumbnail dimmensions');
    imagecopyresampled($slate, $source_image, 0, 0, $x1, $y1, $w, $h, $x2, $y2);
    // If $destination is not set this will output the raw image to the browser and not save the file
    if(!$destination) header('Content-type: image/jpeg');
    @imagejpeg($slate, $destination, 75) or die('Directory permission problem');
    ImageDestroy($slate);
    ImageDestroy($source_image);
    if(!$destination) exit;
    return true;
}

So, WSOD means that its some sort of die without a message. Any ideas?

回答1:

Just to verify is the post_max_filesize set to a high level? Because according to php.net:

If the size of post data is greater than post_max_size, the $_POST and $_FILES superglobals are empty. This can be tracked in various ways, e.g. by passing the $_GET variable to the script processing the data, i.e. <form action="edit.php?processed=1">, and then checking if $_GET['processed'] is set.

Something to consider.

for more info see this link and scroll down to the post_max_filesize section

UPDATE

In my experience if you're getting a WSOD it's usually do to error_reporting and display_errors being turned off OR the memory_limit being reached. In the script at the top I usually set the memory_limit to 1024M to verify that isn't the problem and the turn on error_reporting and display_errors... so put this before the file upload:

error_reporting(E_ALL); // or E_STRICT
ini_set("display_errors",1);
ini_set("memory_limit","1024M");

That normally gets rid of the WSOD and gives you and error to work with.

UPDATE

Have you tried taking off the @ error suppression in front of all your functions to see they are producing a specific error? Also what are you execution and input timeouts? and Can you verify what headers are being sent? (make sure it is Content-Type=text/html;)

回答2:

Try changing the target path to a non temp directory.

After some of the updates here is the resolution:

set_time_limit(0);
ini_set('upload_max_filesize', '500M');
ini_set('post_max_size', '500M');
ini_set('max_input_time', 4000); // Play with the values
ini_set('max_execution_time', 4000); // Play with the values

...add this to the beginning of your file that processes the upload.

回答3:

[error] => 1 means The uploaded file exceeds the upload_max_filesize directive in php.ini.
http://www.php.net/manual/en/features.file-upload.errors.php

So, you have to change your settings.

as for the php.ini file you posted here, it just doesn't affect your PHP. you have to move it somewhere to more proper location

I had the same problem last week, it was just because my server space disk was full! I hope it will help someone...

回答5:

I had same problem, but I wanted to overwrite a file, so I have to delete old file and than it works.
