I have something like this in the route:
Route::post('/iteminfo/{item_id}','itemcontroller#get_item_info');
And something like this in the controller
public function get_item_info($request)
{
$item_image = Item_Image->where("item_id",$request)->first();
$item_something = Item_Something->where("item_id",$request)->first();
$item_more = Item_More->where("item_id",$request)->first();
return Response::json($item_image);
}
I want to return the 3 things but with return Response::json() I can only return 1 statement (as far as I know). Is there any way to return all of them?
You can pass an array as the json response. So craft an array based on your data and use it.
return Response::json(array(
'item_image' => $item_image,
'item_something' => $item_something,
'item_more' => $item_more,
));
Since it requires an Array parameter so you can construct an array from the variables
return response()->json(['item_image ' => $item_image, 'item_something' => $item_something, 'item_more' => $item_more ]);
Or
return Response::json(['item_image ' => $item_image, 'item_something' => $item_something, 'item_more' => $item_more ]);

I've some problems to return a paginator object as HAL json collection. I'm using the latest versions of zend-expressive and zend-expressive-hal.
This is the setting from my ConfigProvider:
public function __invoke() : array
{
return [
'dependencies' => $this->getDependencies(),
MetadataMap::class => $this->getHalConfig(),
];
}
public function getHalConfig() : array
{
return [
[
'__class__' => RouteBasedCollectionMetadata::class,
'collection_class' => RoleCollection::class,
'collection_relation' => 'user_roles',
'route' => 'api.user.roles',
],
];
}
And these are my handler methods:
public function get(ServerRequestInterface $request) : ResponseInterface
{
// read some records from the database
$select = new Select();
$select->from(['r' => 'user_roles']);
$select->columns(['id', 'name']);
$paginator = new RoleCollection(new DbSelect($select, $this->dbAdapter));
$paginator->setItemCountPerPage(25);
$paginator->setCurrentPageNumber(1);
return $this->createResponse($request, $paginator);
}
private function createResponse(ServerRequestInterface $request, $instance) : ResponseInterface
{
return $this->responseFactory->createResponse(
$request,
$this->resourceGenerator->fromObject($instance, $request)
);
}
The RoleCollection class is only an inheritance of the Paginator:
class RoleCollection extends Paginator
{
}
The error message which I get is:
Cannot generate Zend\Expressive\Hal\HalResource for object of type ArrayObject; not in metadata map
I think you are missing the metadata for the Role object itself.
For example this is something similar for my posts object:
MetadataMap::class => [
[
'__class__' => RouteBasedCollectionMetadata::class,
'collection_class' => Posts::class,
'collection_relation' => 'posts',
'route' => 'api.posts',
],
[
'__class__' => RouteBasedResourceMetadata::class,
'resource_class' => Post::class,
'route' => 'api.posts.view',
'extractor' => ArraySerializable::class,
],
],
You have only described the collection and the resource class is missing for a single role.
I also see the resource generator tries to parse an ArrayObject. This should be wrapped in a Role object, which you can add to the MetadataMap.
Where it goes wrong in your code is this line:
$paginator = new RoleCollection(new DbSelect($select, $this->dbAdapter));
This adds the result of a query into the paginator, but the paginator does not know how to handle it. If I remember correctly, the DbSelect return a ResultSet. I'm guessing this is where the ArrayObject is coming from. What you probably need is to override that ResultSet and make sure it returns an array of Role objects. You might want to look into the dbselect adapter and the hydrating resultset.
Once you have the Role object in the paginator, you can describe it in the metadata.
[
'__class__' => RouteBasedResourceMetadata::class,
'resource_class' => UserRole::class,
'route' => 'api.roles',
'extractor' => ...,
],
I use doctrine myself with hal so zend-db is out of my scope. If you need more help, I suggest the zf forums.
What I am trying to achieve:
I have a table with a type field which holds integer values. These integer values represent different strings.
I want to be able to search the table using the string values that the integers represent.
E.g type = abc rather than type = 0.
What have I tried:
I have created a query class for the model and tried to make use of the $boolean_map property:
class ReportQuery extends FilterableQuery
{
protected $filterable = [
'type' => 'LIKE',
'removed_the_rest'
];
protected $boolean_map = ["type" => [ 'addacs' => 0, "arudd" => 1,]];
}
Then I have overridden the find method of the model to use the query class:
public static function find()
{
$query = new ReportQuery(get_called_class());
return $query;
}
And in the search model I have:
public function search($params)
{
$query = Report::find();
$dataProvider = new ActiveDataProvider([
'query' => $query
]);
$this->load($params, '');
if (!$this->validate()) {
return $dataProvider;
}
// grid filtering conditions
$query->andFilterWhere([
'type' => $this->type,
]);
$query->andFilterWhere(['like', 'type', $this->type]);
return $dataProvider;
}
When searching by the string values I get an empty result. Searching by the integer values produces the data.
Any help is appreciated. Thanks.
Maybe it's better for you to make filter on that column instead of searching by string. You can do it for string as follows.
$filter = [
'example1' => 1,
'example2' => 2,
'example3' => 3,
];
$query->andFilterWhere(['like', 'type', $this->filter[$this->type]);
or in this place
// grid filtering conditions
$query->andFilterWhere([
'type' => $this->filter[$this->type],
])
also you can make filter dropdown on column, and for dropdown of that filter you can pass this array and just do
$query->andFilterWhere([
'type' => $this->type,
])
Why do you create mapping mechanism in query object? Okay, you show integer type as a string in frontend of your application, but the query shouldn't have details of representation. You should map string type to integer type in your search model. For example:
class ReportSearchModel extends ReportModel
{
public function mapType($value)
{
$items = [
'addacs' => 0,
'arudd' => 1
];
return array_key_exists($value, $items) ? $items[$value] : null;
}
public function search($params)
{
//another code
$query->andFilterWhere([
'type' => $this->mapType($this->type),
])
//another code
}
}
The alternative way is using an enum instead of mapping.
I'm having an issue rendering a Twig view and a JSON response, I need to call the twig view and pass it a new Json response with a variable as parameter. The output error is the following "Notice: Object of class Symfony\Component\HttpFoundation\Response could not be converted to int
"
Here is the code
$resultado = array('mes1_local' => $mes1_local, 'mes2_local' => $mes2_local, 'mes3_local' => $mes3_local, 'mes1_online' => $mes1_online, 'mes2_online' => $mes2_online, 'mes3_online' => $mes3_online, 'contador_pedido_local' => $contador_pedido_local, 'contador_pedido_online' => $contador_pedido_online, 'contador_total' => $contador_total, 'contador_usuarios' => $contador_usuarios);
return new JsonResponse($resultado, $this->render('others/adminlte.html.twig'));
Like #goto's answer, but it won't works, cause you need to use renderView instead of render:
return new JsonResponse([
'things' => $thingsArray,
'anotherVariable' => $simpleVariable,
'html' => $this->renderView('others/adminlte.html.twig', []/* template parameters goes here */),
]);
The Json Response signature is
__construct(mixed $data = null, int $status = 200, array $headers = array(), bool $json = false)
You are trying to give the twig to the status parameter.
You can avoid this silly error by using a good IDE
To give additional data to your response you could structure your array data returned
return new JsonResponse([
'someData' => $resultado,
'html' => $this->render('others/adminlte.html.twig')
);
In Yii2 framework is it possible to add a new attribute dynamically to an existing object, which is retrieved from Database?
Example
//Retrieve from $result
$result = Result::findone(1);
//Add dynamic attribute to the object say 'result'
$result->attributes = array('attempt' => 1);
If it is not possible, please suggest an alternate best method to implement it.
Finally I would be converting the result to a json object. In my application, at the behaviour code block, I have used like this:
'formats' => [
'application/json' => Response::FORMAT_JSON,
],
You can add define a public variable inside your model, that will store dynamic attributes as associative array. It'll look something like this:
class Result extends \yii\db\ActiveRecord implements Arrayable
{
public $dynamic;
// Implementation of Arrayable fields() method, for JSON
public function fields()
{
return [
'id' => 'id',
'created_at' => 'created_at',
// other attributes...
'dynamic' => 'dynamic',
];
}
...
..in your action pass some dynamic values to your model, and return everything as JSON:
public function actionJson()
{
\Yii::$app->response->format = \yii\web\Response::FORMAT_JSON;
$model = Result::findOne(1);
$model->dynamic = [
'field1' => 'value1',
'field2' => 2,
'field3' => 3.33,
];
return $model;
}
In result you will get JSON like this:
{"id":1,"created_at":1499497557,"dynamic":{"field1":"value1","field2":2,"field3":3.33}}
I need to get the count of a JSON array returned by symfony 2.7 controller action.
This is my controller
<?php
namespace Eagle\ShopBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Template;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpFoundation\Request;
class CartController extends Controller {
/**
* #Route("/cart/add")
* #Template()
*/
public function addAction(Request $request) {
$items = Array(
166 => Array(
'quantity' => 2,
'price' => 7
),
165 => Array(
'quantity' => 1,
'price' => 7
)
);
//convert to json using "JMSSerializerBundle"
$serializer = $this->container->get('serializer');
$jsonproducts = $serializer->serialize($items, 'json');
return new Response($jsonproducts);
}
}
And this is my ajax call,
$.post("http://localhost:8000/cart/add", function (data) {
alert(data.length);
});
I need to get the count of items from array(2), but I get 63 inside alert box.
As I see, you got string in response. You need smth like:
$.post("http://localhost:8000/cart/add", function (data) {
var json = $.parseJSON(data); //parsing response string into JSON Object
var length = Object.keys(json).length; //A little bit crappy way to get JSON Object length, but it works
alert(length);
});
Or, of course you could use the way provided by #Put12co22mer2 - it is even better.
If you return a response , the 63 is the number of chars in the string (actually the response is a html string) ... You've to return a JsonResponse
You don't need the #Template()
Something like :
<?php
namespace Eagle\ShopBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Template;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\JsonResponse; // <---- LOOK HERE
class CartController extends Controller {
/**
* #Route("/cart/add")
*/
public function addAction(Request $request) {
$items = Array(
166 => Array(
'quantity' => 2,
'price' => 7
),
165 => Array(
'quantity' => 1,
'price' => 7
)
);
return new JsonResponse($jsonproducts); // <---- LOOK HERE
}
}
