The following solution addresses the need to automatically delete image files associated with ads from your media library. To enable the automatic deletion of a media image linked to an ad unit upon deletion, add the following code snippet to the functions.php file.

add_action( 'before_delete_post', 'delete_ad_image', 99, 2 );

function delete_ad_image( $post_id, $post ) {
    if ( $post->post_type !== 'advanced_ads' ) {
        return;
    }

    if ( EMPTY_TRASH_DAYS && $post->post_status !== 'trash' ) {
        return;
    }

    $ad_options = get_post_meta( $post_id, 'advanced_ads_ad_options', true );

    if ( empty( $ad_options ) ) {
        return;
    }

    $ad_options = maybe_unserialize( $ad_options );
    if ( is_array( $ad_options ) && isset( $ad_options['output']['image_id'] ) ) {
        $image_id = $ad_options['output']['image_id'];

        if ( get_post( $image_id ) ) {
            wp_delete_attachment( $image_id, true );
        }
    }
}Code language: PHP (php)

Please exercise caution when implementing this code, as it directly impacts the media library and the ads associated with the deleted images. Notably, if you utilize the same image banner file across multiple ads and delete one, including the image file, the related ads will stop working. Custom modifications like these can potentially affect other functionalities within Advanced Ads.
