I found this code.

But not work for me. Where to insert the code? I try

wp-content/theme/mytheme/functions.php - not work.

wp-includes/post.php - not work.

wp-includes/functions.php - not work.

And I make plugin (but this the first), not work. Plugin download.

My Wordpress version is 4.2.2.

Big Thanks, and sorry I'm rookie!

• 1 which solution you are trying to use (out of the two, given in so question)? I'd suggest not to edit the WordPress core files directly, wp-includes/post.php, wp-includes/functions.php, never edit those files – Kumar Commented May 15, 2015 at 9:23
• I trying insert the code in above php - not work. After I trying make plugin (link above) - not work. Okey, I don't edit core files! (My English maybe not good sorry) – Aron Commented May 15, 2015 at 10:23

Just for clarity: borrowing from this answer, add the following to your theme's functions.php:

function wpse_188427_delete_post_media( $post_id ) {
    $attachments = get_posts(
        array(
            'post_type'      => 'attachment',
            'posts_per_page' => -1,
            'post_status'    => 'any',
            'post_parent'    => $post_id,
        )
    );
    
    foreach ( $attachments as $attachment ) {
        wp_delete_attachment( $attachment->ID );
    }
}

add_action( 'before_delete_post', 'wpse_188427_delete_post_media' );

// Uncomment the following line if you also want to delete media when the post is trashed
// add_action( 'wp_trash_post', 'wpse_188427_delete_post_media' );
