Question

I am learning CakePHP 2.0, and created a sample test application, where user can submit a file at the time of registration.

below is the database table

users Table

id Auto_Increment
first_name
last_name
email
doc_file

And also created User.php and UsersController.php

and below are the content code in UsersController.php

UsersController.php

class UsersController extends AppController{

    public $helpers = array('Html', 'Form');


    public function index(){
        $this->set('user1', $this->User->find('all'));
    }


    public function register(){
        if ($this->request->is('post')){
            if ($this->User->save($this->request->data)){
                //move_uploaded_file($this->data['Model']['field']['tmp_name'], WWW_ROOT.DS.'xxx');

                move_uploaded_file($this->data['User']['doc_file']['tmp_name'], WWW_ROOT.DS.'hello.doc');

                $this->Session->setFlash('User is created');
                $this->redirect(array('action'=>'index'));
            } else {
                $this->Session->setFlash('Cannot register a user');
            }
        }
    }
}

And in Views, I have created a two files ie index.ctp and register.ctp with a directory Users in View directory

code content of register.ctp

register.ctp

<?php

    echo $this->Form->create('User', array('type'=>'file'));
    echo $this->Form->input('first_name', array('label'=>'First Name'));
    echo $this->Form->input('last_name', array('label'=>'Last Name'));
    echo $this->Form->input('email');
    echo $this->Form->input('doc_file', array('type'=>'file'));
    echo $this->Form->end('Register');
?>  

And when run this page, and fill up all information, it gives an error

Error: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'Array' in 'field list'

And below is the query I got, where it is inserting an array into doc_file

SQL Query: INSERT INTO `database_db`.`users` (`first_name`, `last_name`, `email`, `doc_file`) VALUES ('master', 'shifu', '[e-mail]', Array)

What i am trying :

While user is registering, the file name should be random and it should be move to

localhost/mysite/app/webroot/files/user_data/ or
localhost/mysite/app/webroot/files/user_data/user_id_directory/

its good, if it creates the userid directory and storing the file in its parent user directory

Answer 1

The problem is that CakePHP is seeing the doc_file field and trying to insert it into the database.

After Cake has processed the form submission, doc_file contains an array of values.

You can fix it by doing the following:

In your view:

echo $this->Form->input('new_doc_file', array('type'=>'file'));

In your controller:

if ($this->request->is('post')){
    $this->data['User']['doc_file'] = WWW_ROOT.DS.'hello.doc';
    if ($this->User->save($this->request->data)){
        move_uploaded_file($this->data['User']['new_doc_file']['tmp_name'], $this->data['User']['doc_file']);

        $this->Session->setFlash('User is created');
        $this->redirect(array('action'=>'index'));
    } else {
        $this->Session->setFlash('Cannot register a user');
    }
}

(ie. upload the file with a temporary field name, manually add the doc_file field to the post array before you try to save).
