No $ _POST variable available after submitting a form

Hi

I have a question about the acf_form () function. Problem is: I create a normal page in the backend of my CPT and insert my shortcode here that contains the acf_form (). Now I would like to have the $ _POST variable output after submitting the form. On any other post_type, however, it does not work for my own CPT.
I get an empty array () back here.
What could be the reasons?

<?php

if (isset($_POST)) {
	echo '<pre>';
	print_r($_POST);
	echo '</pre>';
}

acf_form_head();

$options = array(
	'post_id'	         => 'new_post',
	'field_groups'		 => array( 25 ),
);

acf_form( $options );

?>

$_POST is not set when you are displaying an admin page.

When you submit a post the post is processed, nothing is displayed, once the processing is done you are redirected back to the edit page, $_POST is not included.

Hey John,

Thanks for your answer. I have just solved the problem. Apparently acf_form_head () causes that I cannot access the $ _POST variable because it is completely deleted once during the redirect. Thank you for answering anyway. Maybe some didn’t know that?

P.S: In addition, I am not creating an admin page, but a normal field_group with the ID.
