advanced custom fields plugin last input field in new posts

I have managed it to work i was trying not to work on with hooks like the plugin developers suggest, but the solution was with hook.

Here is the documentation example of the plugin

But i need to edit the content of the post too so i make a loop to find the post you can create a query to get it too it will be ok too. So i get the content like this:

<?php
$current_post = isset($_GET['post'])?intval($_GET['post']):'new';
acf_form_head(); 
?>
<?php get_header(); ?>
<?php
    if($current_post!='new')
       {
?>
<?php 
      $query = new WP_Query( array( 'post_type' => 'post', 'posts_per_page' => '-1', 'page_id'=>$current_post,'author'=>$current_user->ID ) ); ?>
<?php if ( $query->have_posts() ) : while ( $query->have_posts() ) : $query->the_post(); ?>
<?php
        $title = get_the_title();
        $content = get_the_content();
        $post_categories = wp_get_post_categories( get_the_ID() );
        $cats = array();

        foreach($post_categories as $c){
            $cat = get_category( $c );
            $cats[] = $cat->cat_ID;
        }

?>
<?php endwhile; endif; ?>
<?php wp_reset_query(); ?>
<?php }
    else
    {
        $title="";
        $content="";
    }
?>

And then in the function.php i have a filter which get the information when the form is submitted like this:

function my_pre_save_post( $post_id )
{   
    $current_post = isset($_GET['post'])?intval($_GET['post']):'';
    if($_POST['cat'])
    {
        $cats = $_POST['cat'];
        foreach($cats as $catp)
        {
            $catobject = get_category($catp,false); // Get the Category object by the id of current category
            if($catobject->category_parent); // the id of the parent category 
            {
                array_push($_POST['cat'],$catobject->category_parent);
            }
        }
        $_POST['cat']=array_unique($_POST['cat']);
    }
// Create a new post
$post_information = array(
'post_title' =>  wp_strip_all_tags( $_POST['postTitle'] ),
'post_content' => $_POST['postContent'],
'post_type' => 'post',
'post_status' => 'pending',
'post_category'=>$_POST['cat']
);

if($current_post)
{
        $post_information['ID'] = $current_post;
}

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

$_POST['return'] = add_query_arg( array('post' => $post_id), $_POST['return'] );    

// return the new ID
return $post_id;
}

Also i clear some options in the options table with fields starting with “new_” and add this code to separate the new post from the old when call the advanced custom fields visualization.

<?php $args = array(
                'post_id' => $current_post ,
                'field_groups' => array( 19 )
            );

            acf_form( $args );  ?>

This things resolve my problem so i wanted to share with someone which experience the same problems.
