PHP Warnings

Hi there,

i get PHP warnings in Query Monitor regarding your Plugin:

Undefined index: shownav wp-content/plugins/wp-post-comment-rating/inc/function.php:176
Undefined index: wpcr_social wp-content/plugins/wp-post-comment-rating/inc/function.php:177

Its regarding to the content filter in that file, while i have both options not active, the seem to be undefined with your method of getting options.

global $wpdb, $post;
$results = $wpdb->get_results( "SELECT option_value FROM ".$wpdb->prefix."options WHERE option_name = 'wpcr_settings'");
$getval = unserialize($results[0]->option_value);
$navval = $getval['shownav'];
$wpcr_socialshare = $getval['wpcr_social'];

you should check for existance of the array values befor accessing it:

global $wpdb, $post;
$results = $wpdb->get_results( "SELECT option_value FROM ".$wpdb->prefix."options WHERE option_name = 'wpcr_settings'");
$getval = unserialize($results[0]->option_value);
$navval = isset($getval['shownav']) ? $getval['shownav'] : false;
$wpcr_socialshare = isset($getval['wpcr_social']) ? $getval['wpcr_social'] : false;

as alternative you can get options the “normal” way so you could remove the global $wpdb:

$wpcr_options = get_option('wpcr_settings');
$navval = isset($wpcr_options['shownav']) ? $wpcr_options['shownav'] : false;
$wpcr_socialshare = isset($wpcr_options['wpcr_social']) ? $wpcr_options['wpcr_social'] : false;
