Metabox现时值不允许更新

更正在自定义帖子类型上保存metabox数据时遇到问题。我想我通过在这篇帖子上应用建议来解决这个问题：Metabox nonce PHP notice

这确实消除了警告，但使我无法更新元数据库。以下是相关代码：

function save_goal_info_meta( $post_id ) {
    global $goal_info_meta_fields;

    // verify nonce
    if ( ! isset( $_POST[\'product_noncename\'] ) || ! wp_verify_nonce( $_POST[\'goal_info_meta_box_nonce\'], basename( __file__ ) ) ) {
        return $post_id;
    }

    // check autosave
    if ( defined( \'DOING_AUTOSAVE\' ) && DOING_AUTOSAVE ) {
        return $post_id;
    }

    // check permissions
    if ( \'page\' == $_POST[\'post_type\'] ) {
        if ( ! current_user_can( \'edit_page\', $post_id ) )
            return $post_id;
    } elseif ( ! current_user_can( \'edit_post\', $post_id ) ) {
        return $post_id;
    }

    // loop through fields and save the data
    foreach ( $goal_info_meta_fields as $field ) {
        if ( $field[\'type\'] == \'tax_select\' )
            continue;

        $old = get_post_meta( $post_id, $field[\'id\'], true );
        $new = $_POST[$field[\'id\']];

        if ( isset( $new ) && ! empty( $new ) && ( $new != $old ) ) {
            update_post_meta( $post_id, $field[\'id\'], $new );
        } elseif ( \'\' == $new && $old ) {
            delete_post_meta( $post_id, $field[\'id\'], $old );
        }
    }
}

add_action( \'save_post\', \'save_goal_info_meta\' );

我或多或少理解为什么它没有更新，但如果没有“未定义的索引”，我似乎无法修复它。

$goal_info_meta_fields = array(

   array(
    \'label\' => \'Home Goals by:\',
    \'desc\' => \'Add and select home scorers\',
    \'id\' => $prefix.\'home-scorers\',
    \'type\' => \'home_player_list\'
   ),
   array(
    \'label\' => \'Away Goals by:\',
    \'desc\' => \'Add and select away scorers\',
    \'id\' => $prefix.\'away-scorers\',
    \'type\' => \'away_player_list\'
   )
);

以下是输出：
