        $photo = new WP_Http();
        $photo = $photo->request( $article->largeURL );
        $attachment = wp_upload_bits( $photo_name . '.jpg', null, $photo['body'], date("Y-m", strtotime( $photo['headers']['last-modified'] ) ) );

        $filetype = wp_check_filetype( basename( $attachment['file'] ), null );

        $postinfo = array(
            'post_mime_type'    => $filetype['type'],
            'post_title'        => $article->heading . ' ',
            'post_content'  => '',
            'post_status'   => 'inherit',
        );
        $filename = $attachment['file'];
        $attach_id = wp_insert_attachment( $postinfo, $filename, $newId );
        if( !function_exists( 'wp_generate_attachment_data' ) )
            require_once(ABSPATH . "wp-admin" . '/includes/image.php');
        $attach_data = wp_generate_attachment_metadata( $attach_id, $filename );
        wp_update_attachment_metadata( $attach_id,  $attach_data );
        set_post_thumbnail($newId,$attach_id)

It uploads the image to the media but doesn’t set as the featured image, however i think the problem is in the image upload, the attachment screen in the ‘media’ looks as follow

Which seems to suggest some information hasnt come through correctly as theres no thumbnail, name or type.

All help much appreciated!
Thanks

  1. I would comment, but I’m not allowed yet.

    1) Are you doing this from the back-end or front-end? You may need a nonce key.
    2) On set_post_thumbnail, does $newId = $post->ID? That may be why it’s not attaching as the featured image.
    3) Your filename is not preserving the extension/$photo_name is not defined in the code. You may be better off with wp_handle_upload.
