File Uploads: Behavior And/action

Hello everyone.

I have tried several extensions for handling file uploads, but I am not satisfied entirely.

I need to be able to handle regular files (Word and Excel files, for example) as well as images for saving and post processing.

So, I decided that I needed to separate the upload itself from the actions I need to perform on different kind of files.

I created an upload behavior, which basically checks for errors uploading and validates some basic options, like file size and type and it works fine.

But I got stuck on the next step, which is to use that file for something.

So, I’ve got my controller:

class SubirController extends Controller


    public function behaviors()


	    return array(







    public function actionDoSomething()


	    /* here I want to do something with the uploaded file */



And this is the behavior:

class UploadFile extends CBehavior {

    // PHP File Upload error message codes:


    protected $error_messages = array(

        1 => 'The uploaded file exceeds the upload_max_filesize directive in php.ini',

        2 => 'The uploaded file exceeds the MAX_FILE_SIZE directive that was specified in the HTML form',

        3 => 'The uploaded file was only partially uploaded',

        4 => 'No file was uploaded',

        6 => 'Missing a temporary folder',

        7 => 'Failed to write file to disk',

        8 => 'A PHP extension stopped the file upload',

        'max_file_size' => 'File is too big',

        'min_file_size' => 'File is too small',

        'accept_file_types' => 'Filetype not allowed',

        'max_number_of_files' => 'Maximum number of files exceeded',

        'max_width' => 'Image exceeds maximum width',

        'min_width' => 'Image requires a minimum width',

        'max_height' => 'Image exceeds maximum height',

        'min_height' => 'Image requires a minimum height',

        'min_height' => 'Image requires a minimum height',

        'missingFileName' => 'Unnamed file',

        'uploaded_file' => 'Error identifying uploaded file'


    public $files;


	public function __construct()





    public function rearrange_array()


    	$uploaded_files = array();

    	$var_name = array_keys($_FILES);

    	$var = $var_name[0];

    	if (sizeof($_FILES[$var]) > 0) {

    		foreach($_FILES[$var]['name'] as $n=>$data) {

    			$uploaded_files[] = array(









		return $uploaded_files;



    protected function get_error_message($error) {

        return array_key_exists($error, $this->error_messages) ?

            $this->error_messages[$error] : $error;



    public function start()


    	$files = array();

	    if (sizeof($_FILES) > 0) {

	    	$uploaded_files = $this->rearrange_array();

	    	foreach($uploaded_files as $file) {

	    		$uploaded_file['error'] = 1;

	    		$file['error_message'] = $this->get_error_message($uploaded_file['error']);

	    		if ($file['error_message'] == '') {

	    			if ($file['name'] != '') {

	    				if ($file['size'] > 0) {

			    			if (is_uploaded_file($file['tmp_name'])) {


			    			} else {

				    			$file['error_message'] = $this->get_error_message('uploaded_file');


			    		} else {

			    			$file['error_message'] = $this->get_error_message('min_file_size');

			    			$file['status'] = false;


	    			} else {

		    			$file['error_message'] = $this->get_error_message('missingFileName');

		    			$file['estatus'] = false;


	    		} else {

		    		$file['estatus'] = false;


	    		$files[] = $file;



	    echo CJSON::encode($files);



When I run the controller, I get the JSON response on my browser, but what I want to do is, once the file is uploaded and checked by the behavior, do something with the file with a function or action, like read an Excel file or manipulate a JPG.

How do I communicate the behavior and the action? Or maybe I am using a wrong approach?


I think you can use owner property of the behavior, in this case is the controller, than you can call ActionDoSomething(). I think you have to convert the owner property to SubirController class or discovery other way to call this action or maybe put this action on CControler class.

Maybe you can put this function in a model and put this behavior in this model and use the owner property to access the model and the function.

I don´t know what i said above is the right approach.
