[SOLVED] Function not working with multiple arrays?

[lpxxfaintxx]

So basically, I am using a script that automatically grabs an image and create a thumbnail. It works like a charm on a different enviroment where only 1 image is uploaded, but when I try to upload multiple files, I get several errors.

 

 

foreach ($_FILES["pictures"]["name"] as $key => $value) {

$uploaddir = 'albums/'.$album.'/original/'; //a directory inside
$uploadfile = $uploaddir . basename($_FILES["pictures"]["name"][$key]);

if (move_uploaded_file($_FILES["pictures"]["tmp_name"][$key], $uploadfile)) { echo $value . ' uploaded<br>'; }

include 'cropimage.php';


$crop = new Crop_Image_To_Square;
$crop->source_image = $_FILES['pictures']['tmp_name'][$key];

$ext = end(explode('.', $_FILES['pictures']['name'][$key]));

$crop->save_to_folder = 'albums/'.$album;  
$crop->new_image_name = basename($_FILES["pictures"]["name"][$key]);

$process = $crop->crop('center');

 

 

cropimage.php:

Any ideas? Any other ways of creating thumbnails for multiple images?

 

Thanks

I don't see any instance constructor to initialize your $this->source_image.

 

Edit: got it, you do it "externally" (which is bad, unmodularized, that's why I didn't see it at first sight). I'll look at it.

Did you echo '<pre>'; var_dump($_FILES["pictures"]); echo '</pre>'; at the top of the processing script to see if the files were actually uploaded?

[Andy-H]

$uploaddir = 'albums/'.$album.'/original/'; //a directory inside
$uploadfile = $uploaddir . basename($_FILES["pictures"]["name"][$key]);

if (move_uploaded_file($_FILES["pictures"]["tmp_name"][$key], $uploadfile)) { echo $value . ' uploaded<br>'; }

include 'cropimage.php';


$crop = new Crop_Image_To_Square;
$crop->source_image = $_FILES['pictures']['tmp_name'][$key];

 

Isnt that moving the file to a different location then requesting the file from the location from which it was moved?

 

Also, what permissions are the files set to and does it require extra permissions?

This is where it all starts. It means i cannot find the file you are trying to upload.

do a vardump or print_r on $_FILES["pictures"] to see if it are multiple images you are sending.

print_r($_FILES["pictures"])

 

And what does your upload form look like ?
