Trying to fetch data from db
in controllers
$model = new CreateBookings();
$data = CreateBookings::model()->findByPk();
return $this->render('view', [
'data' => $data,
]);
in view :
<?php echo $data->booking_id?>
can somebody tell me what am i doing wrong?
The alternative for Yii1 findByPk in Yii2 is findOne($id)
$model = CreateBookings::findOne($id);
or the equivalent
$model = CreateBookings::find()
->where(['id' => $id])
->one();
for your view you can use
$data = CreateBookings::findOne($id)) ;
and you should have the $id value.
Answering My own question:
I wanted to show database values in my View.
In controller actionView I added-
$data = CreateBookings::findOne($id);
and rendered
'data' => $data,
To show value in view I used
<?php echo Html::encode($data->booking_id);?>

I need to use the function in my view/template page.
My code:
public function getAppNumber($id = null){
$aPPLICATIONINFO = $this->AppEstLto->APPLICATIONINFO->find('all', [
'fields'=>['application_number'],
'conditions'=>['application_id'=>$id],
'limit' => 200
]);
foreach($aPPLICATIONINFO as $aPPLICATIONINFO){
$aPPLICATIONINFOx = $aPPLICATIONINFO;
}
return $aPPLICATIONINFOx;
}
You can use set() to use the function variables in your view as given in cookbook:https://book.cakephp.org/3/en/views.html#setting-view-variables
public function get_app_number($id = null){
$applicationInfo = $this->AppEstLto->APPLICATIONINFO->find('all',
[
'fields'=>['application_number'],
'conditions'=>['application_id'=>$id],
'limit' => 200
]);
//Create an array
$applicationArray = new array();
//Store all results in array
foreach($applicationInfo as $application){
$applicationArray = $application;
}
// Pass the array to view
$this->set(compact('applicationArray'));
}
Now, you can use it in your view:
get_app_number.ctp:
<?php
foreach($applicationArray as $application)
{
echo $application['application_number'];
}
?>
You should be doing something like this in your routes.php file inside your Config folder:
Router::connect('/get-app-number', array('controller' => 'yourController', 'action' => 'get_app_number'));
That way you will be able to connect the url that will be used for your view.
Your action corresponds and sends data to your view.
The action is the function that is inside your controller in which you developed for setting the data and variables.
The example of the slug which would be generated:
http://localhost/get-app-number
I just created a project to try Algolia search solution and it's working good, but I'm not able to return a JSON response.
Here is my code
controller:
/**
* #Route("/api/search/user/{query}", name="search_query")
*/
public function searchAction($query)
{
$entityManager = $this->getDoctrine()->getManagerForClass(User::class);
$users = $this->indexManager->search($query, User::class, $entityManager);
if($users) {
$result = $this->renderView('xxx/search_user.html.twig', [
'users' => $users
]);
return new JsonResponse(['success' => true, 'users' => [$result]]);
}
return new JsonResponse(['success' => false, 'users' => []]);
}
html:
{{ users[0].username }}
This code is working but only returning 1 user not all users, idem if I do a loop inside my twig file it will render all users but not in a good way:

Thanks for the help and sorry for my english.
this is because twig creates the view on the server after the response.
I suggest you to simply create the users array directly inside the controller and remove the part of render view.
for example :
foreach($users as $user) {
$result[]['name'] = $user['name'];
}
and then use $result.
I hope it helps you, Regards
I have two different queries which are saved in two variables.I want to pass the variables to view page from controller.
public function getApprovalList(){
// $users = select query..
// $request = select query..
return view('travelerHome',['users'=>$users,'request'=>$request]);
}
solution:
controller
return view('travelerHome',['users'=>$users,'requestList'=>$request]);
view
#foreach ($requestList as $req)
{{$req->traveler_name }}
#endforeach
return view('travelerHome')->with(array('users'=>$users,'request'=>$request));
You can use return view('travelerHome', compact('users', 'request')); too
Do like this
return view('travelerHome')->with('users'=>$users)->with('request'=>$request);
Code with you have written that is correct, you need to remove the comment only, I am also using the same method for pass the variable to View. Here is the example.
return view('admin.product.product.edit', ['product' => $product,
'attribute_set' => $productAttributes,
'category' => $cates,
'images' => $images,
'status' => $status,
'countries' => $countries,
'crane_manufacture' => $crane_manufacture,
'product_category' => $productCategory]);
}
And it's also working
So, in your code you need to
public function getApprovalList(){
$users = 'select query..';
$request = 'select query..';
return view('travelerHome',['users'=>$users,'request'=>$request]);
}
I'm using a custom datasource to consume webservice.
Create, Read and Update work well but Delete doesn't works.
Here is my code calling the delete method in my controller.
public function delete($id){
$this->autoRender = false;
debug($this->Article->delete($id));
}
And here the code in my datasource
public function delete(Model $Model, $id = null) {
echo "Display a message if this method is called";
$json = $this->Http->post(CakeSession::read('Site.url') . '/webservice/delete/', array(
'id' => $id,
'apiKey' => $this->config['apiKey'],
'model' => $Model->name
));
$res = json_decode($json, true);
if (is_null($res)) {
$error = json_last_error();
throw new CakeException($error);
}
return true;
}
But when I want to delete an item, the debug(); display false.
I have no other displays.
I don't understand why my delete method isn't called correctly.
Is there something wrong in my code ?
Thanks
Let's check: you're only passing a parameter to your method:
$this->Article->delete($id)
According to the method that you created, the first parameter, which is required, is the Model. The second is $id:
public function delete(Model $Model, $id = null)
During the method you want to use both parameters. Here:
'id' => $id
And here:
'model' => $Model->name
Based on this, you need to review how this method will be called. BTW, if you want override delete() method, according the book, you need something like this: delete(int $id = null, boolean $cascade = true).
How can I pass the model in array format.
I want to pass models in this format from controller to view:-
Users[user_contact]=Contact
Users[user_contact][contat_city]=City
Users[user_contact][contact_state]=state
This is what I am doing
public function actionCreate() {
$user = new Users;
$presContact = new Contacts;
$presCity = new Cities;
$presState = new States;
$contactArr = array();
// Uncomment the following line if AJAX validation is needed
// $this->performAjaxValidation($model);
if (isset($_POST['Users'])) {
$transaction = CActiveRecord::getDBConnection()->beginTransaction();
$contactArr = CommonFunctions::saveContact($_POST['Users']['user_pres_contact'],'user_pres_contact',$errorArr);
$presContact = $contactArr['contact'];
$presCity = $contactArr['city'];
$presState = $contactArr['state'];
$user->attributes = $_POST['Users'];
$user->user_pres_contact_id = $presContact->contact_id;
if($user->save()){
$transaction->commit();
$this->redirect(array('view', 'id' => $user->user_id));
} else {
$transaction->rollback();
}
}
$this->render('createUser', array(
'Users' => $user,
'Users[\'user_pres_contact\']'=>$presContact,
'Users[\'user_pres_contact\'][\'contact_city\']'=>$presCity,
'Users[\'user_pres_contact\'][\'contact_state\']'=>$presState,
));
}
I am able to access only $users but
I m not able to access $Users['user_pres_contact'] in the view
That's because you are assigning them as strings...
The correct way of doing things would be (btw, what you are asking for can't done literally, it is impossible to assign 2 values to one key):
$user = array(
'user_press_contact' => array(
'contact' => $presContact,
'city' => $presCity,
'state' => $presState,
),
);
$this->render('createUser', array(
'Users' => $user,
));
It will give you $Users['user_press_contact']['contact'] for the name in the view, etc.
You can use
$user->getAttributes() //it returns an array of data.
Hope that's usefull
It is possible to solve this using model relations? You can define a relation from the User model to the City model (e.g. naming it relation_to_city), then you can just assign the user model in the controller
$this->render('view', 'user'=>$user);
and access the city (from the view)
$user->relation_to_city
