I am working on a web application that allow users to have video conferences. Users are allowed to create video conferences and I want them to be able to also edit the scheduled video conferences but I am having trouble implementing that. Please help.
Edit button in index.php view
$html .= CHtml::ajaxLink('Edit',
Yii::app()->createAbsoluteUrl('videoConference/update/'.$vc->id),
array(
'type'=>'post',
'data' => array('id' =>$vc->id,'type'=>'update'),
),
array( "visible" => $ismoderator, 'role' => "button", "class" => "btn btn-info")
);
Video conference Controller actionUpdate
/**
* Updates a particular model.
* If update is successful, the browser will be redirected to the 'view' page.
* #param integer $id the ID of the model to be updated
*/
public function actionUpdate($id)
{
$model = $this->loadModel($id);
if (isset($_POST['VideoConference'])) {
$model->attributes = $_POST['VideoConference'];
if ($model->save())
$this->redirect(array('view', 'id' => $model->id));
}
$this->render('edit', array(
'model' => $model,
));
}
The first step is to find where is problem(frontend / backend). You need call action without ajax(just from url with param id). Try my version:
/**
* Updates a particular model.
* If update is successful, the browser will be redirected to the 'view' page.
* #param integer $id the ID of the model to be updated
*/
public function actionUpdate($id)
{
$model = $this->loadModel($id);
if ($model == null) {
throw new CHttpException(404, 'Model not exist.');
}
//if (isset($_POST['VideoConference'])) {
//$model->attributes = $_POST['VideoConference'];
$model->attributes = array('your_attr' => 'val', /* etc... */);
// or try to set 1 attribute $model->yourAttr = 'test';
if ($model->validate()) {
$model->update(); //better use update(), not save() for updating.
$this->redirect(array('view', 'id' => $model->id));
} else {
//check errors of validation
var_dump($model->getErrors());
die();
}
//}
$this->render('edit', array(
'model' => $model,
));
}
If on server side all working fine(row was updated) then check request params, console, tokens etc. Problem will be on frontend.
After troubleshooting a little I finally got it to work.
On the view I am calling the actionUpdate method like this:
$html .= CHtml::button('Edit', array('submit' => array('videoConference/update/'.$vc->id), "visible" => $ismoderator, 'role' => "button", "class" => "btn btn-info"));
On the controller just changed
$model->save() to $model->update()
and it works perfectly fine.

I am rendering ajax form
public function actionUser()
{
$model = new UserInfoForm();
$model->user_id = $this->user->id;
$validation = $this->performAjaxValidation($model);
if(null !== $validation){
return $validation;
}
$user = Yii::$app->user->identity;
return $this->renderAjax('user.php',[
'error' => $error,
'user' => $user,
'model' => $model
]);
}
And in user.php, i am having following line to get all user companies and jobs
Show User Companies and Jobs
Now in user details action
public function actiondetails()
{
$model = new UserJobsForm();
$validation = $this->performAjaxValidation($model);
if(null !== $validation){
return $validation;
}
$companies = Companies::getUserCompanies();
$jobs = BlogPost::getUserJobs();
return $this->renderAjax('user_info.php',[
'error' => $error,
'model' => $model,
'companies' => $companies,
'jobs' => $jobs
]);
}
In my user_info.php view page, i am able to see all the details. I am also seeing user.php view page, this is because, i am rendering user_info page on top of user.php. My requirement is not to open in new page. so i am trying to render on top of user.php. I want to close user.php as soon as user_info.php rendered. How can i do this??
If you just want to close another modal, you can call the script below in the user_info view
<script type="text/javascript">
$(function(){
$('#id_of_user_modal').modal('hide');
});
</script>
In ZF2, I have a custom form element factory. It creates a custom MultiCheckbox and fills the checkbox values and labels from a db query.
class MyMultiCheckboxFactory
{
public function __invoke(FormElementManager $formElementManager)
{
$multiCheck = new \Zend\Form\Element\MultiCheckbox();
$serviceManager = $formElementManager->getServiceLocator();
$mapper = $serviceManager->get('Path\To\Mapper\To\Query\DB');
$descriptions = $mapper->findDescriptions($id);
// some processing to prepare $value_options array
$multiCheck->setOptions([
'label' => 'blah-blah',
'value_options' => $value_options
]);
return $multiCheck;
}
}
My problem is as follows. The method findDescriptions($id) depends on the $id which I can get from the route. But when I use MyMultiCheckbox in the form like this:
public function init()
{
$this->add([
'type' => 'Path\To\MyMultiCheckbox',
'name' => 'someName'
]);
}
I don't know how to pass the $id into the MyMultiCheckbox.
Could anyone help pleeeeeeeeeease?
You can fetch the id via the 'route match' instance inside the factory.
$event = $serviceManager->get('Application')->getMvcEvent();
$id = $event->getRouteMatch()->getParam('id', false);
if (empty($id)) {
throw new ServiceNotCreatedException('id not set!');
}
$descriptions = $mapper->findDescriptions($id);
I am working on a job site,And want to show only the jobs posted by a particular user in cgridview.My actuall aim is to authenticate the user so that only jobs posted by him/her will be visible in cgridview.I have done the following stuff,but not working.
In controller:
public function actionViewJob() {
$user_id = Yii::app()->session['user_id'];
/* For User Authentication */
if (Yii::app()->user->getId() === null)
$this->redirect(array('site/login'));
/* For User Authentication */
/* Have tried the following codes to filter */
$model= ViewJob::model()->findAll(array(
'select'=>'*',"condition"=>"user_id='$user_id'",
));
// $model=ViewJob::model()->findByAttributes(array('user_id'=>Yii::app()->user->id));
// $model = ViewJob::model()->findAll("user_id=$user_id");
$model = new Viewjob('search');
$params = array('model' => $model,
);
$this->render('viewjob', $params);
}
In view
$this->widget('zii.widgets.grid.CGridView', array(
'dataProvider' =>$model->search()
// 'filter' => $model, /* not using this option ,so commented it */
))
In model
// Do I really Need This Function //
public function search() {
$criteria = new CDbCriteria;
$criteria->compare('user_id', $this->user_id, true);
return new CActiveDataProvider('viewjob', array(
'criteria'=>$criteria,
));
},,
What am I doing wrong here.It is still fetching all the available rows in table.
You define $model 3 times:
$model= ViewJob::model()->findAll(array(
'select'=>'*',"condition"=>"user_id='$user_id'",
));
Then
$model = new Viewjob('search');
And
'dataProvider' =>$model->search()
Choose one that you need, better last. And add to controller
$model->user_id = $user_id
It will works.
Create new CDbCriteria object and add condition using it and pass it to model.
In Controller:
public function actionViewJob() {
$criteria = new CDbCriteria ();
$criteria->condition = 'user_id=' . Yii::app()->user->id;
$model = ViewJob::model()->findAll($criteria);
$params = array('model' => $model);
$this->render('viewjob', $params);
}
And in View, simply:
$this->widget('zii.widgets.grid.CGridView', array(
'dataProvider' =>$model
Also for use Authentication, in your controller you don't need to check, if user has the user id, simply add access rules, which will automatically redirect user to the login page to view the job and once they are logged-in, will return them to the same page. So, add this at the top of our controller..
class YourController extends Controller {
public function filters() {
return array(
'accessControl', // perform access control
);
}
/**
* Specifies the access control rules.
* This method is used by the 'accessControl' filter.
* #return array access control rules
*/
public function accessRules() {
return array(
array('allow', // allow all users to perform 'index' and 'view' actions
'actions' => array('index', 'view'),
'users' => array('*'),
),
array('allow', // allow authenticate user actions
'actions' => array('viewjob'),
'users' => array('#'),
),
array('deny', // deny all users
'users' => array('*'),
),
);
}
I am working on a job site.And using Yii.I have gridview which list all the jobs posted by user,but I just want to show the jobs which are posted by a particular user.like if the user is logged in as admin then it should show only jobs posted by admin.I have tried the following things but not working.
In Controller.
//codes
public function actionViewJob() {
$user_id = Yii::app()->session['user_id'];
/* For User Authentication */
if (Yii::app()->user->getId() === null)
$this->redirect(array('site/login'));
/* For User Authentication */
$model = ViewJob::model()->find(array(
'select' => array('*'), "condition" => "user_id= $user_id",
));
$params = array('model' => $model,
);
$this->render('viewjob', $params);
}
function as search() in model ViewJob.
public function search()
{
$criteria=new CDbCriteria;
$criteria->compare('key_skills','Admin',true);
return new CActiveDataProvider('viewjob', array(
// 'criteria'=>$criteria,
'sort'=>array(
'defaultOrder'=>'key_skills ASC',
),
));
}
What am I doing wrong here.?.Its still listing the whole data.
Try like
$model=ViewJob::model()->findByAttributes(array('user_id'=>Yii::app()->user->id));
Try this
$model = ViewJob::model()->findAll("user_id=$user_id");
/*
1. find() can fetch first matched row, where as findAll() fetches all matched rows in the db table
2. "user_id=$user_id" is equals to WHERE user_id=$user_id
*/
Code improvements(Yii way)
Register user sessions as bellow
Yii::app()->user->setState('user_id',$value_variable); //Set the session
Yii::app()->user->getState('user_id'); //Get the session
You can use accessRules() for bellow code
if (Yii::app()->user->getId() === null)
$this->redirect(array('site/login'));
Like
public function accessRules()
{
return array(
array('allow',
'actions' => array('viewJob'),
'users' => array('#'),

my app is a Book manager where I can create Books and Pages.
I have my bookController with a "store" on POST, which store a title and a description.
public function store()
{
$rules = array(
'title' => 'required|min:3',
'description' => 'required|min:30'
);
$validator = Validator::make(Input::all(), $rules);
if ($validator->fails()) {
return Response::json(
array(
'metadata' => array(
'error' => true,
'message' => 'The book creation has failed'
)
),
400
);
}
else {
$slug = Str::slug(Request::get('title'));
$existSlug = Book::where('slug',$slug)->get();
if(count($existSlug) > 0) {
return Response::json(
array(
'metadata' => array(
'error' => true,
'message' => 'This title is already taken'
)
),
400
);
}
else {
$book = new Book;
$book->title = Request::get('title');
$book->slug = $slug;
$book->description = Request::get('description');
$book->user_id = Auth::user()->id;
$book->status = false;
$book->save();
$stored = $book->toArray();
$metadata = array(
'metadata' => array(
'error' => false,
)
);
return Response::json(
array_merge($stored,$metadata),
201
);
}
}
}
I also have a pageController with a "store" on POST, which store a page content :
public function store()
{
$rules = array(
'content' => 'required|between:300,350',
'book_id' => 'required|exists:books,id'
);
$validator = Validator::make(Input::all(), $rules);
if($validator->fails()) {
return Response::json(
array(
'metadata' => array(
'error' => true,
'message' => 'The page must be between 300 and 350 characters'
)
),
400
);
}
else {
$book = Book::find(Input::get('book_id'));
$content = Input::get('content');
$parent = Page::where('book_id',$book->id)->where('status',1)->orderBy('id', 'desc')->first();
if($parent){
$parent_id = $parent->id;
$parent_number = $parent->number;
$status = 0; //Define the status of the created page
}
else{
//If it's the first page of the book
$parent_id = 0;
$parent_number = 0;
$status = 1; //if there's no parent page, the new page is the first - auto validated - page of the book.
if($book->user_id != Auth::user()->id) {
return Response::json(
array(
'metadata' => array(
'error' => true,
'message' => 'You have to be the author of a book to write the first page.'
)
),
403
);
}
}
$page = new Page;
$page->content = $content;
$page->book_id = $book->id;
$page->parent_id = $parent_id;
$page->number = $parent_number + 1;
$page->user_id = Auth::user()->id;
$page->status = $status;
$page->save();
$stored = $page->toArray();
$metadata = array(
'metadata' => array(
'error' => false
)
);
return Response::json(
array_merge($stored,$metadata),
201
);
}
}
Whenever someone creates a book, he has to write at least its first page. This result in a form with an input title, description and content.
I send a POST to [...]/books with my input title and description
If Success => I get the book id, and send it with the input content to [...]/pages.
Here are my problems :
Someone can send a post on [...]/books and will store a new book with no page
I want to solve this in the more "restFUL way", meaning no "hackish solution" like sending the content to /books and make a page validation in the bookController
Also, even if I chose the hackish way, my API is still not safe : I can stop the second request (to /pages) to be sent.
How do I handle this co-dependency ?
1st
Your controllers are doing too much, they are not supposed to know anything about your business logic this is something that should be handle by specific classes (models, repositories, domain logic classes).
Create some classes to handle this logic, send the Input to them and make it happen. Call them whatever you need to, using Laravel is great because you can do whatever you want with your code.
2nd
If you have different data constraints to be enforced, you can:
Handle them on the same request
Depends on your interface, if you have everything you need on a single page, you just send the data and handle it on a repository, which has access to all your models.
An example that can be used for both could be:
A book repository using Dependency Injection, which means that Book and Page will be automatically instantiated by Laravel:
class BookRepository {
__construct(Book $book, Page $page)
{
$this->book = $book;
$this->page = $page;
}
public function store($input)
{
if ( ! $this->book->validate($input) || !$this->page->validate($input))
{
return 'error';
}
$book->create(input);
$page->create($input);
}
}
A Base Model with your validation:
class Book extends BaseModel {
public function validate($input)
{
/// validate here and return
}
}
Your models and rules for each:
class Book extends BaseModel {
$book_rules = array(
'title' => 'required|min:3',
'description' => 'required|min:30'
);
}
class Page extends BaseModel {
$page_rules = array(
'content' => 'required|between:300,350',
'book_id' => 'required|exists:books,id'
);
}
And then you create your view having book info and page info, and which will POST to BookController#store:
class BookController extends Controller {
public function __controller(BookRepository $book_repository)
{
$this->book_repository = $book_repository;
}
public function store()
{
if ( ! $this->book_repository->store($input))
{
return Redirect::back()
->withErrors(
$this->book_repository
->validation
->messages()
->all()
);
}
return Redirect::to('success');
}
}
Again we are using Dependency Injection. $book_repository will be instantiated automatically. So your Controller doesn't need to know what a Book or a Page do, it just need to get the request and pass to a repository that will take care of everything.
It's not all there, but it's a start.
Handle them on different requests
This is usual. User send a request, app check and store data. User send a second request, app check it all and send back errors, if needed.
Handle them in background
This is a smarter way to do it. Your app will receive all data, in one or more requests, store them, check them using a queue worker and send e-mails to the user telling him that there are some data to be filled. Books with no pages can be deleted after some time. You don't risk having bad data and your user will know what's missing as soon as you do too.
