Re: Comparable 2.xx to 3.xx functionality

I think to read a bit more of how php works, it will help you understand much better how to work with CakePHP. I don't know a good tutorial for learning PHP, though.
You can also google about the new features in the language since PHP 5.3, specially the changes in 5.4 since you look confused about the use of square brackets.

Thanks, but neither seem to work...

You suggested, $allTitles = $articles->find()->extract('title');

I tried $users->find()->extract('temp_key') but gives an error of 

Call to a member function find() on a non-object

You suggested $this->User->validates(array('fieldList' => array('email', 'password')))

I tried $this->User->validates(array('fieldList' => array('email'))) but gives an error of

Unknown method "validates"

I wouldn't have thought that the second solution would have worked anyway as 3.xx seems to have done away with the use of the word array in favour of square brackets. why I don't know?

In fact, I've just found an entry on validating in controllers in 'http://book.cakephp.org/3.0/en/orm/table-objects.html' why this isn't in 'http://book.cakephp.org/3.0/en/core-libraries/validation.html', I again don't know. This seems to be a common theme with the new docs, with a lot of useful information scattered across the docs in many different places and not always where you'd expect to find it!

There are several ways to achieve what you want and they are all in the docs. Quoting a few lines from the V3 Book

$allTitles = $articles->find()->extract('title'); //you can add a ->where() to this 

$this->User->validates(array('fieldList' => array('email', 'password')))

Yes your controller looks just about right and it is very easy to understand what to expect as I read further.

Hi,

I am trying to write an app in 3.xx using functionality that I have previously used in 2.xx but despite scouring the docs, I cannot find the answers. Apologies if they are in there, but there seems to be  5x the amount of documentation especially around the new ORM.

In 2.xx I could easily find the value of a single field e.g. $this->User->field('temp_key') Is there a 3.xx equivalent ?

In 2.xx I could validate a field in a model e.g. $this->User->validates(array('fieldList' => array('email'))) Is there a 3.xx equivalent ?

Lastly a general question. The top of my Users controller currently looks like this, and I've not yet finished it...

namespace App\Controller;

use App\Controller\AppController;

use Cake\Network\Exception\ForbiddenException;

use Cake\Event\Event;

use Cake\ORM\TableRegistry;

use Cake\Utility\Security;

use Cake\ORM\Entity;

class UsersController extends AppController {

Does this look right, compared to the simplicity of 2.xx this now looks very unwieldy and complicated?

Thanks for any replies.

Dave
