I created my own admin route.
This is it's controller:

Route controller

<?php


class Mediabase extends MagentoSalesControllerAdminhtmlOrder
 
 public function execute()
 

 $objectManager = MagentoFrameworkAppObjectManager::getInstance();
 $urlInterface = $objectManager->get(MagentoBackendModelUrlInterface::class);
 $mediabaseUrl = $urlInterface->getUrl("uo_mediabase/order/mediabase");

 print_r($this->getRequest()->getPost());
 $currentUrl = $urlInterface->getCurrentUrl();
 

?> 

This is the form which is calling the route

<div class="admin__page-section order-view-billing-shipping">
 <div class="admin__page-section-title">
 <span class="title">Mediabase</span>
 </div>

 <div class="admin__page-section-item-title">
 <span class="title">Bestellnummer</span>
 </div>

 <div class="admin__page-section-item-content">
 Mediabase-Bestellnummer: <?php echo $block->getMediabaseNumber(); ?>
 </div>
 <br/> 
 <form id="mediabase_edit_form" action="<?= $this->getFormUrl() ?>" method="post">
 <input type="text" name="bestellnr"><br/>
 <input class="action-default" type="submit" value="Speichern">
 </form>
</div>

So when the route is called I want to get the

bestellnr

value.

However my form doesn't seem to send POST data.

Do you know how I can achieve that?

Thanks!

First check your controller is being called on form submit or not if it's being called then follow below method

If you want to get post data from controller,
$post = $this->getRequest()->getPostValue();

Here your full code,

Also You have to declare storemanager object inside __construct() function of your php file instead of use dirctly objectmanager.

I have updated your code as below,

class Index extends MagentoFrameworkAppActionAction


 /**
 * @var MagentoFrameworkAppCacheTypeListInterface
 */
 protected $_cacheTypeList;

 /**
 * @var MagentoFrameworkAppCacheStateInterface
 */
 protected $_cacheState;

 /**
 * @var MagentoFrameworkAppCacheFrontendPool
 */
 protected $_cacheFrontendPool;

 /**
 * @var MagentoFrameworkViewResultPageFactory
 */
 protected $resultPageFactory;

 /**
 * @param ActionContext $context
 * @param MagentoFrameworkAppCacheTypeListInterface $cacheTypeList
 * @param MagentoFrameworkAppCacheStateInterface $cacheState
 * @param MagentoFrameworkAppCacheFrontendPool $cacheFrontendPool
 * @param MagentoFrameworkViewResultPageFactory $resultPageFactory
 */
 public function __construct(
 MagentoFrameworkAppActionContext $context,
 MagentoFrameworkAppCacheTypeListInterface $cacheTypeList,
 MagentoFrameworkAppCacheStateInterface $cacheState,
 MagentoFrameworkAppCacheFrontendPool $cacheFrontendPool,
 MagentoFrameworkViewResultPageFactory $resultPageFactory,
 MagentoStoreModelStoreManagerInterface $storeManager
 )
 
 parent::__construct($context);
 $this->_cacheTypeList = $cacheTypeList;
 $this->_cacheState = $cacheState;
 $this->_cacheFrontendPool = $cacheFrontendPool;
 $this->resultPageFactory = $resultPageFactory;
 $this->storeManager = $storeManager;
 

 /**
 * Flush cache storage
 *
 */
 public function execute()
 
 $currentStore = $this->storeManager->getStore();
 $baseUrl = $currentStore->getBaseUrl();

 $post = $this->getRequest()->getPostValue();

 echo "<pre>";
 print_r($post);
 exit;

 

Also, you can check here:

http://clever-code.com/how-to-save-form-data-to-the-custom-table-in-magento-2/

You can use the following code to get post or get values from form to controller action:

Below code will return all the parameters either post or get:

$params = $this->getRequest()->getParams();

If you want only one variable value then you can use the following code:

$variable_name = $this->getRequest()->getParam('variable_name');

In your case you can use the following code to get bestellnr value:

$bestellnr = $this->getRequest()->getParam('bestellnr');
