Magento 2 - How Can I Send Success and Error in JSON and from Frontend update product price and enable/'disable?

Question

Ajax runs on page load i want to run it on button click.

I create one Module and make a custom tab which is display some product with name and price and if the product is enable/disable. I want that user update that price from front-end and enable and disable that product from front-end.[![enter image description here][1]][1]

This is my Controller File

<?php
namespace Deal\Val\Controller\Valuation;
use Magento\Framework\View\Result\PageFactory;
use Magento\Framework\App\Action\Context;
use Magento\Catalog\Model\Product\Attribute\Source\Status;
use Magento\Catalog\Model\ResourceModel\Product\Action;
class Index extends \Magento\Framework\App\Action\Action
{
protected $customerSession;
protected $urlInterface;
protected $customer;
private $productAction;
public function __construct(
    Action $productAction,
    \Magento\Customer\Model\Session $customerSession,
    \Magento\Framework\UrlInterface $urlInterface,
    \Dealers\Validation\Model\Customer $customer,
    \Magento\Framework\App\Action\Context $context
) {
    $this->urlInterface = $urlInterface;
    $this->customerSession = $customerSession;
    $this->customer = $customer;
    $this->productAction = $productAction;
    parent::__construct($context);
}
public function execute()
{
    if(!$this->customerSession->isLoggedIn()) {
        $this->messageManager->addErrorMessage("You must be logged in to view product");
        $this->customerSession->setAfterAuthUrl($this->urlInterface->getCurrentUrl());
        $this->customerSession->authenticate();
        return;
    }
    /$data = $this->getRequest()->getPost();
    $this->customer->saveproduct($data);/
    $productIds = [47];
$storeId = 0;

$attributes = [
    //'status' =&gt; Status::STATUS_ENABLED,
    'price' =&gt; 70
];

$this-&gt;productAction-&gt;updateAttributes($productIds, $attributes, $storeId);
$this-&gt;_view-&gt;loadLayout(); 
$this-&gt;_view-&gt;renderLayout(); 

}
}

This is my Model File

<?php
namespace Deal\Val\Model;
use Magento\Catalog\Model\Product\Attribute\Source\Status;
use Magento\Catalog\Model\ResourceModel\Product\Action;
class Customer
{
/**

@var Action

*/
private $productAction;
public function __construct(
    Action $productAction
) {
    $this->productAction = $productAction;
}
public function execute()
{
    /** Array of product ids */
    $productIds = [47];
/** 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' =&gt; Status::STATUS_ENABLED
];

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

}
}

This is my JS file

require(["jquery"],function($) {
$(document).ready(function() {
$( &quot;#price&quot; ).click(function() {
    let customurl = &quot;&lt;?php echo $this-&gt;getUrl().'customer/valuation/index'?&gt;&quot;;
    let dataid = $(this).data('id');
    $.ajax({
        url: customurl,
        type: 'POST',
        dataType: 'json',
        data: {
            dataid: dataid
        },
        complete: function(response) {             
            console.log(response); 
        },
    });
});


});
console.log('aa');
});

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

In your model file, you first need to load the product, then update it's price and save it.

I am updating your model code:

<?php
namespace Deal\Val\Model;
use Magento\Catalog\Model\Product\Attribute\Source\Status;
class Customer
{
    protected $productRepository;
public function __construct(
    \Magento\Catalog\Api\ProductRepositoryInterface $productRepository
) {
    $this-&gt;productRepository = $productRepository;
}

public function execute()
{
    /** Array of product ids */
    $productIds = [47];
    foreach($productIds as $id){
        $product = $this-&gt;productRepository-&gt;getById($id);
        $product-&gt;setPrice(100); //Update anything here
        $product-&gt;save();
    }
}

}

Hope this will help you resolve your issue.

Can you show full error message? – Shoaib Munir Jul 10 '20 at 17:39
Updated the screenshot of error @Shoaib – Prits Jul 10 '20 at 18:03
instead of calling model file, you can move update product code in your controller. I have also created this type of module where user can update their products, I did the same, updated product in controller file – Shoaib Munir Jul 11 '20 at 09:05
On moving that in Controller file still got the same error " Type Error occurred when creating object " @Shoaib – Prits Jul 11 '20 at 10:15
