As may be abundantly clear I am no longer maintaining this component. It will not be updated for CakePHP 3. It was a learning tool that some few people found useful, but moving forward I'd rather put my time into supporting one of the other S3 libraries on Packagist. Not only framework agnostic but reducing the number of S3 library clones by one.

I'll leave the repo up for posterity and anyone that is still relying on it.

The CakeS3 plugin for CakePHP allows easy integration with an Amazon S3 instance to be dropped into your app.

Utilising tpyo's amazon-s3-php-class, which in his words is..

This class is a standalone Amazon S3 REST implementation for PHP 5.2.x (using CURL), that supports large file uploads and doesn’t require PEAR.

This means it can be dropped in and run on a variety of hosting platforms.

Do one of the following to use this plugin in your CakePHP 2.0 app

git clone https://fullybaked@github.com/fullybaked/CakeS3.git app/Plugin/CakeS3

or

git submodule add https://fullybaked@github.com/fullybaked/CakeS3.git app/Plugin/CakeS3

or

Just download the package and unzip it into your app/Plugin directory

Then remember to add the following to your Config/bootstrap.php

//Add the CakeS3 plugin
CakePlugin::load('CakeS3');

Add the following to your controller $components instance variable

// in controller components var
$components = array(
	'CakeS3.CakeS3' => array(
		's3Key' => 'YOUR_AMAZON_S3_KEY',
		's3Secret' => 'YOUR_AMAZON_S3_SECRET_KEY',
		'bucket' => 'BUCKET_NAME',
		'endpoint' => 's3.amazonaws.com' // [optional] Only required if your endpoint is not s3.amazonaws.com
	)
);

Or add the settings before invoking the Plugin in Config/bootstrap.php

//Add the CakeS3 plugin
Configure::write('CakeS3', array(
		's3Key' => 'YOUR_AMAZON_S3_KEY',
		's3Secret' => 'YOUR_AMAZON_S3_SECRET_KEY',
		'bucket' => 'BUCKET_NAME',
		'endpoint' => 's3.amazonaws.com' // [optional] Only required if your endpoint is not s3.amazonaws.com
		)
);
CakePlugin::load('CakeS3');

And in your controller, only include the Component name

$components = array(
	'CakeS3.CakeS3'
);

####List the contents of a bucket

$contents = $this->CakeS3->listBucketContents();

####List the contents of a path relative to the bucket i.e. a folder

$contents = $this->CakeS3->listFolderContents('path/relative/to/bucket/');

####Upload a file to S3

$response = $this->CakeS3->putObject('/path/to/local/file', 'path/relative/to/bucket/', [$permission]);

The response value is an array with the following values

array(
	'name' => [name of saved file],
	'url' => [path to the resource on S3],
	'size' => [size of the resource on S3]
)

Allowed $permission Values:

The allowed values for permissions are wrapped by the component and are accessed via a wrapper method

$this->CakeS3->permission('private');
$this->CakeS3->permission('public_read');
$this->CakeS3->permission('public_read_write');
$this->CakeS3->permission('authenticated_read');

Example:

$response = $this->CakeS3->putObject('/path/to/local/file', 'path/relative/to/bucket/', $this->CakeS3->permission('authenticated_read'));

####Accessing Files With authenticated_read Permission

$auth_path = $this->CakeS3->authenticateUrl($full_s3_path, [$lifetime]);

If a file is stored on S3 with authenticated_read permissions, it is only accessible via a secure token. This method generates a new URL to reach the resource with the correct token, and a time to live. The default is 30 seconds as generally the URL will be recreated on refresh, but not accessible if copied out of the app

####Delete a file from S3

$response = $this->CakeS3->deleteObject('path/relative/to/bucket/');

####Retrieve an object from S3 location

$object = $this->CakeS3->getObject('path/relative/to/bucket/', [$path_to_store_local_copy = false]);

####Retrieve information about an object on S3

$info = $this->CakeS3->getObjectInfo('path/relative/to/bucket/');

####Change the bucket name on the fly using method chaining

$response = $this->CakeS3->bucket('new_bucket')->{any_of_the_above_methods};

• List contents of given bucket
• List folder contents within a bucket
• Push files to a location on S3
• Retrieve an object from S3
• Retrieve information about an object from S3
• Delete files from S3
• Generate authenticated URL's for protected resources
