How can we set store value in UI form Magento 2

Question

I have a UI form in admin with store switcher. I need store_id in post data.

enter image description here

As all can see store_id in url when I change store from store switcher but once I submit it I am not getting any store value in post data. So I think I need to set store value in a hidden field. I don't know I am on right track or not. Please help guys if anyone faced this issue before.

Answer 1

I just need to set store id in DataProvider file like below.

<?php
namespace Vendor\Module\Model\Providers;
use Vendor\Module\Model\ResourceModel\Company\CollectionFactory;
class DataProvider extends \Magento\Ui\DataProvider\AbstractDataProvider
{
 /**
 * @var array
 */
 protected $loadedData;
 /**
 * @param string $name
 * @param string $primaryFieldName
 * @param string $requestFieldName
 * @param CollectionFactory $taskCollectionFactory
 * @param array $meta
 * @param array $data
 */
 public function __construct(
 $name,
 $primaryFieldName,
 $requestFieldName,
 CollectionFactory $companyCollectionFactory,
 \Magento\Framework\App\Request\Http $request, 
 \Magento\Store\Api\StoreRepositoryInterface $storeRepository, 
 array $meta = [],
 array $data = []
 ) {
 $this->collection = $companyCollectionFactory->create();
 $this->request = $request;
 parent::__construct($name, $primaryFieldName, $requestFieldName, $meta, $data);
 }
 /**
 * Get data
 *
 * @return array
 */
 public function getData()
 {
 if (isset($this->loadedData)) {
 return $this->loadedData;
 }
 $items = $this->collection->getItems();
 foreach ($items as $item) { 
 $item->setStoreId($this->request->getParam('store'));
 $this->loadedData[$item->getEntityId()] = $item->getData();
 } 
 return $this->loadedData;
 }
}

ui_form.xml

<field name="store_id" sortOrder="65" formElement="hidden">
 <argument name="data" xsi:type="array">
 <item name="config" xsi:type="array">
 <item name="source" xsi:type="string">company</item>
 </item>
 </argument>
 <settings>
 <dataType>hidden</dataType>
 <dataScope>store_id</dataScope>
 </settings>
</field>

• Rutvee Sojitra: what if i am using for new and edit action from same . so how can i set store id for new action?
• Ramkishan Suthar: @RutveeSojitra Actually on add form there will be no option of store switcher so it will save as store_id 0 while add. I got inspired from product add/edit form.
• Rutvee Sojitra: Thanks ramkishan . Actually i am migrating magento1 to magento2 and in my magento1 there is functionality to save store id when we add so am finding same for magento2. But no luck
• Juliano Vargas: @Ramkishan Suthar What If the form is empty that means is New how to populate the field? as $this->loadedData returns Array()
• Ramkishan Suthar: @JulianoVargas while adding a new entry store_id will be saved as 0. I checked in default product add/edit form.

Kindly use getting all get, post, and url values in the controller action:

 /** @var \Magento\Backend\App\Action $this*/
 /** @var array $params*/
 $params = $this->getRequest()->getParams();

You can also get each value by:

 /** @var string $store*/
 $store = $this->getRequest()->getParam('store');
