Undefined variable warnings in 1.2.0

  • The plug-in may generate undefined variable warnings. Here are to examples:

    Notice: Undefined variable: meta_title in /nfs/c08/h03/mnt/118357/domains/test.getawaygrey.com/html/blog/wp-content/plugins/wp-social-seo-booster/includes/wps-seo-booster-ogp.php on line 429
    Notice: Undefined variable: meta_description in /nfs/c08/h03/mnt/118357/domains/test.getawaygrey.com/html/blog/wp-content/plugins/wp-social-seo-booster/includes/wps-seo-booster-ogp.php on line 430

    The relevant lines are:

    if( $meta_title ) echo '<meta itemprop="name" content="' . esc_attr( $meta_title ) . '">' . "\n";
    if( $meta_description ) echo '<meta itemprop="description" content="' . esc_attr( $meta_description ) . '">' . "\n";
    if( $meta_image ) echo '<meta itemprop="image" content="' . esc_url( $meta_image ) . '" />' . "\n";

    These lines test the variable value directly, rather than whether the variable is set. isset($meta_...) or ! empty($meta_...) would prevent the warnings. Other lines also test variables directly but did not generate warnings on my WP installation.
