I have errors in WordPress:

PHP Notice: Undefined offset: 0 in /home/userpro/public_html/wp-content/themes/hoon/inc/tweaks.php on line 602

PHP Notice: Trying to get property of non-object in /home/userpro/public_html/wp-content/themes/hoon/inc/tweaks.php on line 602


 * Display Future Posts
 * Display future post in the events category to all users.
function hoon_show_all_future_posts( $posts ) {

    global $wp_query, $wpdb;

    if ( is_single() && $wp_query->post_count == 0 ) {
        $events_cat = hoon_option( 'events_category' );
        $request = $wpdb->get_results( $wp_query->request );
        /* Line 602 bellow  */  
        if ( post_is_in_descendant_category( $events_cat, $request[0]->ID ) || in_category( $events_cat, $request[0]->ID ) ) {
            $posts = $request;
    return $posts;
add_filter( 'the_posts', 'hoon_show_all_future_posts' );
  • This should be done using pre_get_posts, you shouldn't use the_posts to change a query like this

If $wp_query->post_count == 0 I cant see how $wpdb->get_results( $wp_query->request ) would return any posts. So basically

$request = $wpdb->get_results( $wp_query->request );

contains nothing and $request[0] doesn't exist. Ergo

PHP Notice: Undefined offset: 0

It would be interesting to know, what this could is supposed to achieve.


The first error message is for undefined variable which you used $request[0] and second one is for $request is not a object so you cannot use as object.

I suggest you that use below code and check what you missed:

$request = $wpdb->get_results( $wp_query->request );
print('</pre>'); exit;

Above code shows what $request contains.

Let me know if you face any query regarding this OR require more help.

  • Thank you for attention! Where it is necessary to insert the code? I put to the end of the code and the site stopped working (white screen). An error at the end of the code, this latter function. I see this as a Problem related to the function of creating events (my theme) I do not use it, it is possible to disable this feature completely? Aug 1, 2015 at 4:35
  • Place my four line code before /* Line 602 bellow */ comment statement. Code only represent that what $request pull, based on that we can place new(solution) code. Do not place it any where. Aug 1, 2015 at 5:19
  • No change! Error is continued! Here's how I put code in two versions. The only thing that I noticed this change in this post gravitation.pro/jessie-andrews Aug 1, 2015 at 19:39
  • if ( is_single() && $wp_query->post_count == 0 ) { $events_cat = hoon_option( 'events_category' ); $request = $wpdb->get_results( $wp_query->request ); print('<pre>'); print_r($request); print('</pre>'); exit; Aug 1, 2015 at 19:41
