CakePHP File API

Question

I'm currently developing a form to upload a file to the server I'm working on. I can successfully upload a file to one of my app's folder without issue. What I want to do next is to read the file that was uploaded and add its info to a data base. To do this I'm using CakePHP's file API, but I can't get the constructor to work. Here is my code

<?php
App::uses('Component', 'Controller');
App::uses( 'String', 'Utility');
App::uses( 'File', 'Utility');

class UploadComponent extends Component{
    public $max_files = 1;
    public $filePath;


    public function upload($data = null){

        if( !empty( $data ) ){
            if(count ($data) > $this->max_files){
                throw new NotFoundException("Error procesando el pedido, el número máximo de archivos aceptados es {$this->max_files}", 1);
            }
            foreach($data AS $file){
                $filename = $file['name'];
                $file_tmp_name = $file['tmp_name'];
                $dir = WWW_ROOT.'files'.DS.'uploads';
                $allowed = array('txt');
                if( !in_array( substr( strrchr( $filename, '.'), 1), $allowed)){
                    throw new NotFoundException("Error procesando el pedido", 1);
                }elseif(is_uploaded_file( $file_tmp_name)){
                    move_uploaded_file($file_tmp_name, $dir.DS.String::uuid().$filename);
                    $filePath = $dir.DS.String::uuid().$filename;
                    echo gettype($filePath);
                    $import = new File($filePath); //this line throws an error

                }
            }
        }
    }
}

I'm confused as the API says that it receives a path in form of a string, which $filePath is, but it is saying that it's receiving an array. Any idea on how to make it work? These are the errors the framework shows:

dirname() expects parameter 1 to be string, array given [CORE\Cake\Utility\File.php, line 87]

is_dir() expects parameter 1 to be a valid path, array given [CORE\Cake\Utility\File.php, line 88]

basename() expects parameter 1 to be string, array given [CORE\Cake\Utility\File.php, line 89]

Thanks in advance.

I see this errors in your code. Correct this and see if it solves the problem.

 move_uploaded_file($file_tmp_name, $dir.DS.String::uuid().$filename);
 $filePath = $dir.DS.String::uuid().$filename;

each time you call String::uuid() it gives you random uuid. You wont have filePath where you moved file.

It should be

 $filePath = $dir.DS.String::uuid().$filename;
 move_uploaded_file($file_tmp_name, $filePath);

Also you can use debug() function to see what value a variable has.

debug($filePath);
