I want to change the address of the page requested from the controller.
For example: when prompted site / edit return site/edit/12
where 12 - is a number of model.
Of course I can use the redirect, but can be a way to do it is not use a redirect.
My snippet:
public function actionEdit($id = null){
if(!$id){
$model = Portfolio::model()->createEmpty();
$this->redirect('site/edit'.$model->id);// I think that redirect is bad
Yii::app()->end();
}
// ... etc logic
}
public function actionEdit($id = 0){
if($id == 0){
$this->redirect('/site/edit/12');
exit();
}
}
OR
public function actionEdit($id = 0){
if($id == 0){
$id = 12;
}
}
You should do it with an array :
$this->redirect(array('site/edit','id'=>$model->id));
if you want to hide the 'id' in your url, add a url rule in your config file.

I have a table named uri_table that contain:
id, uri_segment
1, /dir_name/bla-bla-1/
2, /dir_name/bla-bla-2/
3, /dir_name/bla-bla-3/
I want to get the pure link that only contain until controller_name and the controller param are not included. but when I use $_SERVER['URI_SEGMENT'] it will get the controller param too.
so I can't do this code below to search in my model:
function check_uri()
{
$this->db->like('uri_segment',$uri_segment,'after');
$id = $this->db->get('uri_table')->row_array()['id'];
return $id;
}
instead of:
function check_uri($request_uri=$_SERVER['URI_SEGMENT'])
{
//trim controller param that is numeric
for($i = strlen($request_uri)-1;$i > 0;$i--)
{
if(is_numeric($request_uri[$i]) || $request_uri[$i]=='/')
{
continue;
}
else
{
$request_uri = substr($request_uri,0,$i+1);
break;
}
}
$this->db->where('uri_segment',$request_uri);
$id = $this->db->get('uri_table')->row_array()['id'];
return $id;
}
This is my code right now but is also can remove param that is number if the $request_uri = '/dir_name/bla-bla-3/1/some_param/3' it'll return $id null. What can I do to remove the param/get uri without controller param or how to compare the $uri_segment to uri_segment ($this->db->like($uri_segment, '%uri_segment%'))?
Do one thing when you create a controller in that store the controller name like this:
class About extends CI_Controller {
// MVC config
var $PANEL = '';
var $CONTROLLER = 'about';
var $MODEL = 'mdl_about';
var $TITLE = 'page title';
var $LIST_PAGE_NAME = 'aboutus';
function About() {
parent::__construct();
//$this->load->model($this->MODEL, 'model');
}
function index() {
$this->load->view($this->LIST_PAGE_NAME);
}
}
So that above controller, model, page title and view page can be use anywhere is related to that controller.
To display the variable value use like this:
echo $this->CONTROLLER;
Or you can try this:
$this->router->fetch_class(); //for controller
$this->router->fetch_method(); //for method
Is there an easy way like in Cakephp 3 to work with roles
APP Controller
public function isAuthorized($user)
{
// Admin can access every action
if (isset($user['role']) && $user['role'] === 'admin') {
return true;
}
// Default deny
return false;
}
POSTS Contoller
public function isAuthorized($user) {
// All registered users can add posts
if ($this->action === 'edit') {
return true;
}
return parent::isAuthorized($user);
}
I know from http://book.cakephp.org/3.0/en/controllers/components/authentication.html#testing-actions-protected-by-authcomponent that
$this->auth->deny('add');
Is doing it, but how can I add the user/admin ?
I have used ACL authentication in very simple way with isAuthorised() method. I hope it would be help you.
AppController.php
you can make have to define property
/**
* ACCESS CONTROL LIST BASED ON METHODS OF CLASS FOR USER ROLES
*/
var $accessControllList = array();
Define private method
private function _checkAccessControll() {
if ($this->Auth->user('id')) {
if (!isset($this->accessControllList) || empty($this->accessControllList)) {
return true;
}
$action_name = $this->request->params['action'];
$user_role = $this->Auth->user('role');
if (isset($this->accessControllList['allowed']) && !empty($this->accessControllList['allowed']) && in_array($action_name, $this->accessControllList['allowed'])) {
return true;
} else if (isset($this->accessControllList['role_base'][$user_role]) && !empty($this->accessControllList['role_base'][$user_role]) && in_array($action_name, $this->accessControllList['role_base'][$user_role])) {
return true;
}
throw new \Cake\Network\Exception\ForbiddenException(__('You not have access for this page'));
}
return true;
}
in isAuthorized() add below line.
$this->_checkAccessControll();
In any controller, you need to mapping your ACL with roles. For you PostsController.php file something as below
/**
* List of all accessible Action from URL
* #var array
*/
var $accessControllList = array(
'allowed' => array('view','index'), // allowed for any role.
'role_base' => array(
'administrator' => array('delete', 'approve'), //specially allowed for administrator only
'publisher' => array('view','create','index','replyComment'), // specially allowed for publisher only
'reader' => array('postComment','replyComment') // specially allowed for reader
)
);
i always get the default page, my default custom page, but it doesn't go to my 404 page... and main config is directing to site/error. And the below is my site/error. What else am I missing?
public function actionError()
{
$this->layout = '/layouts/main';
$error = Yii::app()->errorHandler->error->code;
if(404==Yii::app()->errorHandler->error->code){
$this->render('404');
}
else
$this->render('error', array('error'=>$error));
}
public function actionError() {
$this->layout = '/layouts/main';
$error=Yii::app()->errorHandler->error;
if($error['code'] == 404)
$this->render('404');
else
$this->render('error', array('error'=>$error));
}
Yii::app()->errorHandler->error returns an array with details.. check documentation here..
http://www.yiiframework.com/doc/api/1.1/CErrorHandler#error-detail
i want to change default action of a controller depends on which user is logged in.
Ex. There are two users in my site : publisher and author and i want to set publisher action as default action when a publisher is logged in, and same for author.
what should i do? when can I check my roles and set their relevant actions?
Another way to do this would be setting the defaultAction property in your controller's init() method. Somewhat like this:
<?php
class MyAwesomeController extends Controller{ // or extends CController depending on your code
public function init(){
parent::init(); // no need for this call if you don't have anything in your parent init()
if(array_key_exists('RolePublisher', Yii::app()->authManager->getRoles(Yii::app()->user->id)))
$this->defaultAction='publisher'; // name of your action
else if (array_key_exists('RoleAuthor', Yii::app()->authManager->getRoles(Yii::app()->user->id)))
$this->defaultAction='author'; // name of your action
}
// ... rest of your code
}
?>
Check out CAuthManager's getRoles(), to see that the returned array will have format of 'role'=>CAuthItem object, which is why i'm checking with array_key_exists().
Incase you don't know, the action name will be only the name without the action part, for example if you have public function actionPublisher(){...} then action name should be: publisher.
Another, simpler, thing you can do is keep the default action the same, but that default action simply calls an additional action function depending on what kind of user is logged in. So for example you have the indexAction function conditionally calling this->userAction or this->publisherAction depending on the check for who is logged in.
I think you can save "first user page" in user table. And when a user is authenticated, you can load this page from database. Where you can do this? I think best place is UserIdentity class. After that, you could get this value in SiteController::actionLogin();
You can get or set "first page" value:
if (null === $user->first_page) {
$firstPage = 'site/index';
} else {
$firstPage = $user->first_page;
}
This is a complete class:
class UserIdentity extends CUserIdentity
{
private $_id;
public function authenticate()
{
$user = User::model()->findByAttributes(array('username' => $this->username));
if ($user === null) {
$this->errorCode = self::ERROR_USERNAME_INVALID;
} else if ($user->password !== $user->encrypt($this->password)) {
$this->errorCode = self::ERROR_PASSWORD_INVALID;
} else {
$this->_id = $user->id;
if (null === $user->first_page) {
$firstPage = 'site/index';
} else {
$firstPage = $user->first_page;
}
$this->errorCode = self::ERROR_NONE;
}
return !$this->errorCode;
}
public function getId()
{
return $this->_id;
}
}
/**
* Displays the login page
*/
public function actionLogin()
{
$model = new LoginForm;
// if it is ajax validation request
if (isset($_POST['ajax']) && $_POST['ajax'] === 'login-form') {
echo CActiveForm::validate($model);
Yii::app()->end();
}
// collect user input data
if (isset($_POST['LoginForm'])) {
$model->attributes = $_POST['LoginForm'];
// validate user input and redirect to the previous page if valid
if ($model->validate() && $model->login())
$this->redirect(Yii::app()->user->first_page);
}
// display the login form
$this->render('login', array('model' => $model));
}
Also, you can just write right code only in this file. In SiteController file.
I just started studying programming about 6 months ago and I have really been diving deep into Objective-C. Unfortunately, I don't know any programmers IRL to bounce general questions off of.
What languages are being used when people write programs that will search a website for information and then send it back? For example, if I wanted to write a program that would search weather.com for the daily temperature of the last 30 days in a given location and then send it back as say...an NSArray or NSDictionary, how would i do that? Can I do that in Objective C or is that super-advanced scripting language stuff? If I CAN do it in Objective-C, can someone link to a tutorial or place that may get me started learning that type of stuff? (I don't really know the term for this type of programming so my google searches have been unfruitful.)
I most commonly use PHP and MySQL with CURL

You can do some fun things like Search Engine Results Page queries, etc.

So, you want to know how to write server-side code? Well, in theory you can write that in whatever you want. I also assure you it isn't "super-advanced".
You might find it easiest to get started with PHP. W3schools.com has a fine tutorial.
What you are describing is a crawler (e.g. Google).
Any language that has the ability to send HTTP requests and receive responses can do this (which is most languages).
If you don't care to code this thing from scratch, try downloading an open source crawler framework that will allow for custom plugins to parse the resulting HTML.
For your example, you would tell the crawler what site you want it to crawl (i.e. your weather site), add URI constraints if necessary, and create a custom plugin to parse the weather data out of the HTML it responds with. You can then save that data however you see fit.
