I'm using dectrium rbac. I created the following rule:
<?php
namespace common\rbac;
use yii\rbac\Rule;
class OwnerRule extends Rule
{
public $name = 'isOwner';
public function execute($user, $items, $params) {
if (!isset($params['object'])) return false;
if (!isset($params['object']->author_id)) return false;
return $params['object']->author_id == $user;
}
}
Then I tried to create the rule in the backend, dectrium rbac provides. Doing this I get the error message "Class OwnerRule does not exist". Obviously
if (!class_exists($this->class))
returns true. What might be the reason?

I try to fetch data from database in codeigniter construct function
but getting undefined method error
controller-
class Welcome extends CI_Controller
function __construct()
{
parent::__construct();
$this->load->model('Login');
$this->Login->getadminnav();
}
}
model-
class Login extends CI_Model
{
public function adminnav()
{
$query="SELECT * from adminnav where status='1'";
$query->row_array();
return true;
}
}
You got to load the model you are using first:
$this->load->model('login_model');
$this->Login->getadminnav();
And remember to rename the model to Login_model
Try these pieces of code.
Controller:
class Welcome extends CI_Controller{
function __construct(){
parent::__construct();
$this->load->model('Login');
$this->Login->adminnav();
}
}
Model:
class Login extends CI_Model{
public function adminnav(){
$this->load->database();
$sql = "SELECT * from adminnav where status='1'";
$result = $this->db->query($sql);
return $result;
}
}
I am seeing in your code that-
In controller you didn't start the second bracket after controller name.
You defined the function name as "adminnav" in model but called it as "getadminnav" in Controller
You didn't load the database in model (If you already loaded it in autoload.php then here is not needed)
Anyway please let me know whether your problem is solved or not.
you are calling getadminnav() but in your model the method name is adminnav.and change model name Login to Login_model.
try this:
class Welcome extends CI_Controller{
function __construct(){
parent::__construct();
$this->load->model('Login_model');
$this->Login->adminnav();
}
}
// model
class Login_model extends CI_Model{
public function adminnav()
{
$query="SELECT * from adminnav where status='1'";
$query->row_array();
return true;
}
}
I have a code for checking a session isset or not in Yii2, I added the code inside a function in a controller, this is the code
if(!isset($session['selectedMonth'])){
return $this->redirect(['select-period/month']);
return false;
}
I have over than 50 functions in 10 controllers, I want every function use that code, how do I can make it without put that code in every function one by one?
You could create base controller for your app, and extend all other controllers from it. Then you could add beforeAction() method in this base controller, so it will be used by all controllers that inherit from base controller:
public function beforeAction($action) {
// initialize $session here
if(!isset($session['selectedMonth'])){
Yii::$app->response->redirect(['select-period/month']);
return false;
}
return parent::beforeAction($action);
}
You can create simple behavior that will handle 'before action' event, for example:
use Yii;
use yii\base\Behavior;
use yii\base\Controller;
class RedirectBehavior extends Behavior
{
public function events()
{
return [
Controller::EVENT_BEFORE_ACTION => 'beforeAction',
];
}
public function beforeAction($event)
{
if (Yii::$app->session->has('selectedMonth')){
return;
}
Yii::$app->getResponse()->redirect(['select-period/month'])->send();
}
}
and attach it to your controllers
public function behaviors()
{
return [
'redirect' => [
'class' => RedirectBehavior::className(),
],
];
}
I'm trying to reference the Requests class in Laravel, I've tried so many fixes with the keyword "use" but each time I keep getting Reflection exception
that says app\path\specified doesn't exist. I'm confused.
Here is my code:`
<?php
namespace App\Http\Controllers;
//namespace App\Http\Request;
//use Illuminate\Http\Requests;
//use app\Http\Requests\ContactFormRequest;
use App\Message;
use App\Mail\SendMessage;
use Session;
//use App\Requests;
class AboutController extends Controller
{
public function create()
{
return view ('about.contact');
}
public function store(App\Requests\SendMessageRequest $request)
{
$message = $request->message;
Mail::to('myemail')
->send(new SendMessage($message, $request->email,$request->name));
THE REQUESTS CLASS
<?php
namespace App\Http\Requests;
use Illuminate\Foundation\Http\FormRequest;
class SendMessageRequest extends FormRequest
{
/**
* Determine if the user is authorized to make this request.
*
* #return bool
*/
public function authorize()
{
return false;
}
/**
* Get the validation rules that apply to the request.
*
* #return array
*/
public function rules()
{
return [
//
'name' => 'required',
'email' => 'required|email',
"message" => 'required',
];
}
}
The commented line(//) are what I've tried
SendMessageRequest is the name of my Request class.
Sorry, I can´t comment your post. However can you also send the SendMessageRequest Class? Is that a subclass of the Request in Laravel?
How to implement a method in a class that can be used by everyone users in php ?
My idea is not to repeat the implementation of readsales in each of the entities
i have 3 users:
admin readSales function,
manager readSales function,
employee, insertSale AND readSales function
Is it possible to implement common methods in a single class? And then call each of the methods to the daughter classes?
abstract class commonMethods {
abstract readSales() {
$pdo = new PDO();
//statements
//readSales
//return $list;
}
}
class Manager extends commonMethods {
function readSales(){
return readSales();
}
}
Yes this is possible, what you need is either a trait or an abstract class.
Here's an example with Abstract class :
<?php
/**
* The abstract class
*/
abstract class CommonMethods
{
public function readSales(){
// Your code
}
public function hello(){
echo "Hello";
}
}
/**
* The Class
*/
class Manager extends CommonMethods
{
// No need to add the "readSales" or "hello" method
// Since we had extended them
public function world(){
echo "World";
}
}
$Manager = new Manager;
$Manager->readSales(); // Works!
$Manager->hello(); // Output: "Hello"
$Manager->world(); // Output: "World"
// The final output: "HelloWorld"

My model: as seen below, very basic
class User extends CI_Model
{
function __construct()
{
parent::__construct();
}
function getAll()
{
$this->db->order_by("lastName", "asc");
$this->db->order_by("firstName", "asc");
$this->db->order_by("userName", "asc");
$query = $this->db->get('user');
// test for result
if($query->num_rows() > 0)
{
return $query->result();
}
return NULL;
}
}
My controller: actually part of my controller, every time loading the users/display function by default route, the error (further down) shows up. Should a model loaded in a controller's contructor be available for all other function in the same controller?
class Users extends CI_Controller
{
function __contruct()
{
parent::__construct();
$this->load->model('user');
}
function display()
{
$data['users'] = $this->user->getAll();
$head['pageTitle'] = 'Users Panel';
$this->load->view('security/redirect');
$this->load->view('template/head', $head);
$this->load->view('user/usersPanel', $data);
$this->load->view('template/foot');
}
}
My error: refering to the line, "$data['users'] = $this->user->getAll()", in above controller
A PHP Error was encountered
Severity: Notice
Message: Undefined property: Users::$user
My environment:
Codeigniter 2.1.0;
Mac Lion;
MAMP 2.0;
Shouldn't this:
class Users extends CI_Controller
{
function __contruct()
{
be like this:
class Users extends CI_Controller
{
function __construct()
{
replace contruct with construct.
Shouldn't this:
$data['users'] = $this->user->getAll();
be this:
$data['users'] = $this->user_model->getAll();
sorry
also the model name:
$this->load->model('user_model');
and class name User_model extends CI_Model
All of my CI projects are set up this way.
