Unable to see Featured Image

Unfortunately, our current version doesn’t store images as featured images. But, this is already on our TODO lists. So, we will have this very soon.

As a quick solution, we have prepared a patch for you. Kindly try adding the following code to the bottom of your theme’s functions.php file.

function aiovg_custom_init() {
    add_post_type_support( 'aiovg_videos', 'thumbnail' );
}
add_action( 'init', 'aiovg_custom_init', 11 );

// Works on OLD posts
function aiovg_set_featured_images() {
    if ( false == get_option( 'aiovg_featured_images_inserted' ) ) {
        add_option( 'aiovg_featured_images_inserted', 1 );

        $items = get_posts( array( 'post_type' => 'aiovg_videos', 'post_status' => 'any', 'numberposts' => -1, 'fields' => 'ids' ) );
           
        if ( count( $items ) ) {
            foreach ( $items as $item ) {
                $image_id = get_post_meta( $item->ID, 'image_id', true );
                if ( (int) $image_id > 0 ) {
                    set_post_thumbnail( $item->ID, $image_id );
                }              
            }
        }
    }
}
add_action( 'init', 'aiovg_set_featured_images' );

// Works on NEW posts
function aiovg_custom_save_featured_image( $post_id, $post ) {  
    if ( ! isset( $_POST['post_type'] ) ) {
        return $post_id;
    }

    // Check this is the "aiovg_videos" custom post type
    if ( 'aiovg_videos' != $post->post_type ) {
        return $post_id;
    }
   
    // If this is an autosave, our form has not been submitted, so we don't want to do anything
    if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ) {
        return $post_id;
    }

    // Check if "aiovg_video_sources_nonce" nonce is set
    if ( isset( $_POST['aiovg_video_sources_nonce'] ) ) {      
        // Verify that the nonce is valid
        if ( wp_verify_nonce( $_POST['aiovg_video_sources_nonce'], 'aiovg_save_video_sources' ) ) {
            $image_id = get_post_meta( $post_id, 'image_id', true );
            if ( (int) $image_id > 0 ) {
                set_post_thumbnail( $post_id, $image_id );
            }
        }
    }

    return $post_id;
}
add_action( 'save_post', 'aiovg_custom_save_featured_image', 99, 2 );

Hope this solved your issue!

Thanks for the reply. I added the code to the bottom of my themes functions.pho file and when I go to a video it now shows the option to ‘set featured image’. I can then choose an image which shows in the editor but as soon as I save it disappears. Any ideas on this?

Ignore that last message, looks to be working perfectly! thank you ??
