[Resolved] creating thumbnals

dud3r

Ok, here goes. I have a script that resizes huge images (I got that part) however, I want to use the same code to resize the same uploaded image into thumbnails as well. However, that code doesn't resize the image and copy it into the regular pics folder, AND THEN copy it into the pics folder with a "thumbnail-" prefix. It does one or the other. How can I make it do both?

Here's the code

$dir = $pic_upload_dir; //defined in another file
$max = 100000; 
$allowed=array("jpg"); 
$files_name = (str_rand(7, '123456789').".jpg"); //defined in another file. creatues a random filename

if (($width > $pic_w) || ($height > $pic_h)) {
//---resize start---//
$filename = $_FILES['file_field_main']['tmp_name']; 
$width = 379; 
$height = 281; 
header('Content-type: image/jpeg');  

list($width_orig, $height_orig) = getimagesize($filename);      

if ($width && ($width_orig < $height_orig)) { 
$width = ($height / $height_orig) * $width_orig; 
} else { 
$height = ($width / $width_orig) * $height_orig; 
}    

$image_p = imagecreatetruecolor($width, $height); 
$image = imagecreatefromjpeg($filename); 
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height, $width_orig, $height_orig); 
imagejpeg($image_p, $_FILES['file_field_main']['tmp_name']);
//---resize end---/
}

header("Location: index.php");
move_uploaded_file($_FILES['file_field_main']['tmp_name'], $dir."/".$files_name);

Now I also want it to create another file, the thumbnail file which should be 75x56px ($dir."/thumbnail-".$files_name).

Any help would be appreciated. Thanks.

Anyone?

It's pretty clear that you need to make 2 passes through this functionality:

Already you are working directly on the uploaded file. You create a new image sized to your maximums, and then change the uploaded file content to the created image. Then you move and rename the uploaded file.

You would make a second pass through similar code:
Open the big image
create a thumbnail image
save the thumbnail image as a new file.

Or maybe I'm missing something?

How do I save it as a new file? copy() ?

try looking in the manual [man]imagejpeg [/man]
imagejpeg () creates the JPEG file in filename from the image image. The image argument is the return from the imagecreate() function.

I wrote the following code. However, it works on the test server, but NOT on the server I run the site.

$dir = "/home/virtual/beta/var/www/html/pictures";

move_uploaded_file($_FILES['file_field_main']['tmp_name'], $dir."/".$files_name); //move actual file
//thumbnail attempt
$filename = $_FILES['file_field_main']['tmp_name']; 
$width = 75; 
$height = 56; 
header('Content-type: image/jpeg');  

list($width_orig, $height_orig) = getimagesize($filename);      

if ($width && ($width_orig < $height_orig)) { 
$width = ($height / $height_orig) * $width_orig; 
} else { 
$height = ($width / $width_orig) * $height_orig; 
}    

$image_p = imagecreatetruecolor($width, $height); 
$image = imagecreatefromjpeg($filename); 
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height, $width_orig, $height_orig); 
imagejpeg($image_p, $_FILES['file_field_main']['tmp_name']);
///
move_uploaded_file($_FILES['file_field_main']['tmp_name'], $dir."/"."thumb-".$files_name); //move thumbnail
header("Location: index.php");

Any ideas why? It works on the test server, but not on the real server. Thumbnails are not created on the real server.
The test server runs a more recent version of php tho, I don't know if that has anything to do with it.

nemonoman

2 likely areas to start:
Maybe you're trying to create the thumbnail AFTER you moved the uploaded picture -- so when the script looks for the original, it's gone.

However, if it works in test mode and not in production, this seems unlikely.

Maybe the directory where the thumbnail file is being created is not permissioned for writing. You can try to chmod it to 777. PHP may not have permission to chmod to 777, you may have to do this by other methods (shell, FTP interface, etc.)

dud3r

How do I prevent it from moving the file?

On the test and the target server the directories are CHMOD 777. The same code works on the test server but not on the target server. I've uploaded it to both servers at the same time. I don't know what's wrong. :/

Edit: Nevermind I got it.
