Hi @tsmulugeta
Wow, I do not remember when I last used this function as I resorted to using the repeater fields extension. However, If my memory serves me right, my goal was to create a new post of a custom type and attach an image to it, and not the page that the front end form was generated on. To save the post, this is the code I “think” i placed in my functions.php file to save the custom post. If it helps, I was using this code for a simple online classifieds website to post ads:

function my_pre_save_post( $post_id )
{    
    // check if this is to be a new post
    if( $post_id != 'new' )
    {
        return $post_id
    }

    // Create a new post
    $ad = array(
        'post_status'    => 'published',
        'post_content'   => $_POST['description'],
        'post_title'     => $_POST['title'],
        'post_type'      => 'ads',
        'post_author'    => get_current_user_id(),
        'comment_status' => 'closed',   // if you prefer
        'ping_status'    => 'closed'    // if you prefer
    );  

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

    // set post (ad) terms
    $category = intval( $data['category'] );
    wp_set_object_terms( $post_id, array( $category ), 'ad-categories' );
    wp_set_object_terms( $post_id, explode( ',', $data['tags'] ), 'ad-tags' );

    // now this is where I retrieved the submitted image id
    // from the form and attached it to the post
    attachment_change_parent( $_POST['ad_image'], $post_id );    

    // return the new ID
    return $post_id;
}

add_filter('acf/pre_save_post' , 'my_pre_save_post', 10, 1 );

// this function changes the parent of the attached image to the post
function attachment_change_parent($aid,$pid) {
	global $wpdb;
	$query = "UPDATE {$wpdb->prefix}posts
		SET post_parent = $pid
		WHERE ID = $aid";
	return ($wpdb->query( $wpdb->prepare($query) )) ? true : false;
}

Basically, from the front end form, as soon as the image is uploaded (via javascript), it’s attached to the page on which the form resides, but what I did was during the “pre_save_post” hook, I get the submitted image id and change the id of the page it’s attached to to the post as soon as the post is created.

I hope this makes some sense and I sure hope it points you into finding a solution. I am here in case you need any more explanation with anything.

Thank you!

Hi Elliot,
First off i’d like to thank you for providing this wonderful plugin. It has done wonders for me so far.

I found a dirty hack of using the ‘pre-save-post’ filter function to get the attachment ID and programmatically change the post parent. The function is:

function attachment_change_parent($aid,$pid) {
	global $wpdb;
	$query = "UPDATE {$wpdb->prefix}posts
		SET post_parent = $pid
		WHERE ID = $aid";
	return ($wpdb->query( $wpdb->prepare($query) )) ? true : false;
} 

It works so far but it is not the best option. I will eagerly await your update on this.

Otherwise thanks again. Keep up the good hard work sir!
