class.upload.php

upload.jpg This PHP script uploads files and manipulates images very easily. The perfect script to generate thumbnails or create a photo gallery! It can convert, resize and work on uploaded images in many ways, add labels, watermarks and reflections and other image editing features. It uses the GD library. This script is released under the GNU GENERAL PUBLIC LICENSE Version 2.

version 0.23 released!

Version 0.23 has been released, to fix a bug introduced in 0.22. If version 0.19 introduced many more features, such as image contrast, brightness, tint, color overlay, flip, rotation... addition of text within the image, all configurable... watermarks... and the possibility to work on local files, version 0.20 went further: cropping, borders, frames, graphic filters such as greyscale, negative, threshold filter, but also some more comprehensive error messages, and automatic gestion of file creation and permissions. version 0.21 brought some more feature such as smart cropping. version 0.22 adds web 2.0 style of reflections, more cropping and text capabilities, and support for open_basedir. Check out some demo samples.
What is it?

An example will be more useful than any blurb I can write :

$foo = new Upload($_FILES['form_field']);
if ($foo->uploaded) {
// save uploaded image with no changes
$foo->Process('/home/user/files/');
if ($foo->processed) {
echo 'original image copied';
} else {
echo 'error : ' . $foo->error;
}
// save uploaded image with a new name
$foo->file_new_name_body = 'foo';
$foo->Process('/home/user/files/');
if ($foo->processed) {
echo 'image renamed 'foo' copied';
} else {
echo 'error : ' . $foo->error;
}
// save uploaded image with a new name,
// resized to 100px wide
$foo->file_new_name_body = 'image_resized';
$foo->image_resize = true;
$foo->image_convert = gif;
$foo->image_x = 100;
$foo->image_ratio_y = true;
$foo->Process('/home/user/files/');
if ($foo->processed) {
echo 'image renamed 'image resized',
resized x=100 and converted to GIF';
$foo->Clean();
} else {
echo 'error : ' . $foo->error;
}
}

What does it actually do in this example?

This example uses a file uploaded via a form. With this single file, it will :

* copy the file without any modification
* copy the file after having changed its name to 'foo'
* copy the file, resizing it to x=100, y=auto, converting it to GIF

How does it work?

* the class constructor upload handles a uploaded file (it can also handle a local file)
* some optional parameters can be set up to act on the file during the process
* the process is called with as an argument the destination directory on the server. If some parameters have been set up, the class will rename, resize, convert files and images
* when the uploaded file is not needed anymore, we can delete it using clean.

Why use this class?

* with one uploaded file, you can do as many copies, convertions, resizing you want.
* you can resize each image dimension, or both, keeping the image ratio or not.
* you can choose to resize an image only if it is bigger -or smaller- than the wanted sizes
* you can manipulate the image in many ways, play with colors, add borders, labels and watermarks...
* its use is simplistic but powerful
* more than 60 documented configuration settings
* a lot of variables are set up during the process. You can retrieve all these values after a process.
* error messages are understandable, and a variable log allows you to see what the class does.
* it is already widely used on Internet
* it is free
