how do I access another helper (e.g. FormHelper) from with a new helper method I've built?
class AppHelper extends Helper {
public function generateSpecialInput() {
return $this->Form->input('I\'m special')
}
}
In the above example, Form is the helper I want to use from within my AppHelper::generateSpecialInput method. Should I be passing the FormHelper object into the method, or is there a better way to do it?
see http://book.cakephp.org/2.0/en/views/helpers.html#including-other-helpers
class AppHelper extends Helper {
public $helpers = array('Form');
public function generateSpecialInput() {
return $this->Form->input('I\'m special');
}
}

In my LoginController under Auth, I have used the following codes:
namespace App\Http\Controllers\Auth;
use App\Model\Admin;
use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\AuthenticatesUsers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Input;
use Illuminate\Support\Facades\Validator;
use Illuminate\Support\Facades\Redirect;
use Hash;
use Auth;
use DB;
use App\Model\UserAdmin;
class LoginController extends Controller {
use AuthenticatesUsers;
public function __construct() {
$this->middleware('guest')->except('logout');
}
public function doLogin(Request $request) {
$userdata = array(
'email' => Input::get('email'),
'password' => Input::get('password'),
'status' => '1',
);
if (Auth::guard('admin')->attempt($userdata)) {
return Redirect::intended('/administrator/dashboard')->with('successMessage', 'You have successfully logged in.');
}
}
}
And in UserAdmin (model) under app/Model is as follows:
namespace App\Model;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Support\Facades\DB;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Config;
class UserAdmin extends Authenticatable {
protected $table = 'adminusers';
public $timestamps = false;
protected $fillable = ['firstName', 'lastName', 'email', 'company', 'website'];
public function __construct() {
parent::__construct(); // Don't forget this, you'll never know what's being done in the constructor of the parent class you extended
}
}
After submitting the login details, it shows me the error:
Type error: Argument 1 passed to Illuminate\Auth\EloquentUserProvider::validateCredentials() must be an instance of Illuminate\Contracts\Auth\Authenticatable, instance of App\Model\UserAdmin given, called in /var/www/html/XXXXXX/vendor/laravel/framework/src/Illuminate/Auth/SessionGuard.php on line 379
I suppose that you required to add implements \Illuminate\Contracts\Auth\Authenticatable to your UserAdmin model class definition.
class UserAdmin extends Model implements
\Illuminate\Contracts\Auth\Authenticatable
You must use Authenticatable in User model
for example:
use Illuminate\Foundation\Auth\User as Authenticatable;
class User extends Authenticatable
{
//your code
}
You must declared use AuthenticableTrait for Authenticatable interface.
For example :
use Illuminate\Contracts\Auth\Authenticatable;
use Illuminate\Auth\Authenticatable as AuthenticableTrait;
use Illuminate\Database\Eloquent\Model;
class Company extends Model implements Authenticatable
{
use AuthenticableTrait;
Try and run 'composer dump-autoload' to check for "ambiguous User class resolution". It is likely you have two classes Defined as User Class.
use Illuminate\Foundation\Auth\AuthenticatesUsers;
Then in your model class, extends AuthenticatesUsers instead of Model.
You must extends Authenticatable class and implements JWTSubject in User model
For example :
class User extends Authenticatable implements JWTSubject {
Go to your Model and instead of extending Model, extend User
<?php
namespace App;
class Staff extends \Illuminate\Foundation\Auth\User
{
}
because my component, controller and model has the same name:
<?php
namespace Plug\Controller;
use Plug\Controller\AppController;
class SettingController extends AppController
{
public function initialize(){
parent::initialize();
$this->loadModel('Setting');
$this->loadComponent('Plug.Setting');
}
How do I know how to refer to component or model ?
Check the manual, almost everything is there. Please consider checking the documentation, it's there to be read.
Aliasing Components
One common setting to use is the className option, which allows you to alias components. This feature is useful when you want to replace $this->Auth or another common Component reference with a custom implementation:
// src/Controller/PostsController.php
class PostsController extends AppController
{
public function initialize()
{
$this->loadComponent('Auth', [
'className' => 'MyAuth'
]);
}
}
// src/Controller/Component/MyAuthComponent.php
use Cake\Controller\Component\AuthComponent;
class MyAuthComponent extends AuthComponent
{
// Add your code to override the core AuthComponent
}
In CakePHP each method of a Controller has its own View and the view template file is the name of the method.
class DataController extends AppController
{
public function one()
{
// will render one.ctp
}
public function two()
{
// will render two.ctp
}
}
Accourding to the API documentation there is a $view property of the Controller that specifies the view to render. So I should have the ability to specify a default view file, say all.ctp, for all methods of a controller
class DataController extends AppController
{
public $view = 'all';
public function one()
{
// should render all.ctp
}
public function two()
{
// should render all.ctp
}
}
However this does not work and CakePHP ignores the $view property and continues to look for the template file of the same name as the method.
Is there a way to have a default view without having to insert $this->render('all'); in each of the Controller's methods?
The value is going to be overridden in Controller::setRequest() which is being called in the controllers class constructor.
You could use your controllers beforeFilter() callback instead to set the value:
public function beforeFilter()
{
parent::beforeFilter();
$this->view = 'all';
}
I have a site develop in cakephp 2.x
I want into my controller call a function of another controller like this:
class ProductsController extends AppController {
public $name = 'Products';
public $scaffold;
public $uses = array('Product','Unit');
public function testFunction(){
$this->loadModel('Unit');
$this->Unit->test();
}
}
The function test into UintController.php is this:
public function test(){
echo("test");
}
My model name are Product and Unit.
When I call the function test give me this error:
Error: SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'prova' at line 1
In the function now is empty but give me this error.
I have tried with:
public $uses = array('Unit');
and to cancel the line with $uses.
How can I solve it?
To call a function from another controller you can use the requestAction:
Definition
"This function calls a controller’s action from any location and returns data from the action. The $url passed is a CakePHP-relative URL (/controllername/actionname/params). To pass extra data to the receiving controller action add to the $options array".
Usage
This is what your code would looks like:
class ProductsController extends AppController
{
public $name = 'Products';
public $scaffold;
public $uses = array('Product','Unit');
public function testFunction() {
// Calls the action from another controller
echo $this->requestAction('/unit/test');
}
}
And then in the UnitController:
class UnitController extends AppController
{
public function test()
{
return 'Hello, I came from another controller.';
}
}
Warning
As said in the CakePHP Cookbook:
"If used without caching requestAction can lead to poor performance. It is rarely appropriate to use in a controller or model".
Best solution for you
But, the best solution for you, would be to create a function inside a model and then call from your controller, like this:
class ProductsController extends AppController {
public $name = 'Products';
public $scaffold;
public $uses = array('Product','Unit');
public function testFunction() {
echo $this->Unit->test();
}
}
And in the Unit model:
class Unit extends AppModel
{
public function test(){
return 'Hello, I came from a model!';
}
}
I need to know in a helper in a CakePHP application if the device is mobile, I would love to use $this->RequestHandler->isMobile(), but the request handler component is not available in helpers. Any ideas?
Thanks!
You can import the class and use it anywhere in the framework like so:
App::import('Component', 'RequestHandler'); // import class
$requestHandler = new RequestHandlerComponent(); // instantiate class
$isMobile = $requestHandler->isMobile(); // call method
var_dump($isMobile); // output: bool(true) or bool(false)
(Tested from helper and gives correct results for Firefox and iPhone)
Also, any options you set in the Controller::helpers property will be passed to the helper:
class AppController extends Controller {
public $components = array(/*...*/, 'RequestHandler');
public $helpers = array(/*...*/, 'MyHelper');
public function beforeFilter() {
$this->helpers['MyHelper']['mobile'] = $this->RequestHandler->isMobile();
}
}
You can catch the options array in your helper's constructor:
class MyHelper extends AppHelper {
protected $_defaultOptions = array('mobile' => false);
public function __construct($options) {
$this->options = array_merge($this->_defaultOptions, $options);
}
}
The accepted answer suggests using a component inside a helper which should be avoided as components are for use solely in controllers and will result in errors as mentioned by Anupal.
The simple solution is to use the CakeRequest class that RequestHandlerComponent uses. So in your helper you can do:-
App::uses('CakeRequest', 'Utility');
$isMobile = (new CakeRequest())->is('mobile');
