How to pass success or error in JSON format using Module -> Model

it would be really helpful.

namespace Namespcae\Modulename\Controller\Index;

use Magento\Framework\View\Result\PageFactory;
use Magento\Framework\App\Action\Context;

class Test extends \Magento\Framework\App\Action\Action
protected $_configReader;
protected $_pageFactory;
protected $customer;

public function __construct(
    \Magento\Framework\App\Action\Context $context,
    \Magento\Framework\App\DeploymentConfig\Reader $configReader,
    \Namespcae\Modulename\Model\Customer $customer,
    \Magento\Framework\View\Result\PageFactory $pageFactory)
    $this->_pageFactory = $pageFactory;
    $this->_configReader = $configReader;

public function execute()
   $productIds = [5];

    /** Contains the id of the store in which you would like to enable/disable the product */
    $storeId = 0;

     * You can put any number of product attributes here. However, in the scope of this code we are going to
     * only enable/disable the product.
    $attributes = [
        'status' => Status::STATUS_ENABLED

    $this->productAction->updateAttributes($productIds, $attributes, $storeId);

How can i send response success or error in JSON format.

  • @RahulBarot is right, this question is similar, you can find your answer there, but I didn't get JSON part of your question, why do you want json response from model, we always want response from controller, but I don't understand why from Model? Jul 13, 2020 at 6:12

For json response from your controller just use array and user echo or return in json format. Example code:

public function execute()
    $response = ["success"=>"", "error"=>""];
    $config = $this->_configReader->load();
    $response["base_url"] = $this->getBaseUrl();
    $response["custom_data_1"] = "My data";
    $response["custom_array_1"] = [123,456,789];
    //Condition to check if error
    $response["error"] = "Error occured";
    //Success check
    $response["success"] = "Successfully done";
    return json_encode($response);

if return json_encode($response); not work for you then you can try echo json_encode($response);

In your controller you can also use $this->messageManager->addSuccessMessage("Success message here") or $this->messageManager->addErrorMessage("Error message here")

For base url part, you can use this code in any of the js

], function($,url){
    varBaseUrl = url.build('');
    //Your other code here
  • Give me error " Type Error occurred when creating object " @Shoaib

    You don't have to pass id, you need to assign html in div with class, something like this jQuery(".mainProduct .name").html(result.product.name) for this you need to set data of product in your controller response Jul 14, 2020 at 5:01
