I've created a custom form in my backend.

I can access it via /admin/export/export/index.

But when I submit my form, Magento is redirecting me to my admin home page. My form needs only to have 1 button to trigger the export of some data.

See my phtml :

<form method="POST" action="<?php echo $block->getUrl('export/export/index')?>">
 <input type="hidden" name="action" value="export">
 <button type="submit">Exporter les données</button>
</form>

and my controler :

 public function execute()

 if('POST' == $this->getRequest()->getMethod()) //not going inside 
 die("post"); 
 $this->_redirect('/admin/export/export/index');
 

 $this->_view->loadLayout();
 $this->_view->renderLayout();

You are getting this error because all of the post requests need to have a valid form_key value sent.

try adding this inside your form tag.

<?= $block->getLayout()->getBlock('form_key');?>

BUt I'm not sure if that works for admin forms.

If that does not work, try this:

add this in the block that renders the form

private $formKey;

public function __construct(
 ...
 MagentoFrameworkDataFormFormKey $formKey,
 ....
) 
 ....
 $this->formKey = $formKey;


public function getFormKey()

 return $this->formKey->getFormKey();

Now you can add this to your form

<input type="hidden" name="form_key" value="<?= $block->getFormKey();?>" />
