Hey,
My snippet works properly when I want to create the post, I just can’t update the created post. I can’t understand how to update the post with acf_form action in the front end, thanks for your help.

std-update.php

acf_form(array(
     'post_id'		=> '',
     'field_groups'	=> array( 19250 ),
     'post_title'	=> false,
     'updated_message' => __("Post updated", 'acf'),
     'submit_value'	=> 'Send',
     'return' => ''
  ));

function.php

	function register_update_std_profile( $post_id )
	{
	    if( $post_id == 'new_post' ) {
	        // Create a new post
	        $post = array(
	            'post_title' => $_POST['fields']['field_123456'],
	            'post_type'  => 'students_profile',
							'post_status'	=> 'publish'
	        );

	        // insert the post
	        $post_id = wp_insert_post( $post );

	        return $post_id;
	    }
	    else {
	        return $post_id;
	    }
	}
	add_filter('acf/save_post' , 'register_update_std_profile');

In the acf_form() call you need to provide the post ID of the post that needs to be edited.

if (some condition) {
  // the if needs to detect if a post is being edited
  // if it is then set $post_id to the post to be edited
  $post_id = $post=>ID; // something like this
} else {
  // otherwise this is a new post
  $post_id = 'new_post';
}

acf_form(array(
     'post_id'		=> $post_id,
     'field_groups'	=> array( 19250 ),
     'post_title'	=> false,
     'updated_message' => __("Post updated", 'acf'),
     'submit_value'	=> 'Send',
     'return' => ''
  ));

Thank you, John
It’s my crazy to forgot to use the acf_form() in a while loop to update a specific post, also you’re right I forgot to pass the post ID to the action too.
Here is my complete code to update a specific post:

while ( $author_posts->have_posts() ) : $author_posts->the_post();

    acf_form(array(
        'post_id'       => get_the_ID(),
        'field_groups'	=> array( 15 ),
        'post_title'    => false,
        'post_content'  => false,
        'submit_value'  => __('Update meta')
    ));
    endwhile;
