How to address undefined offset 0 in wordpress's query.php when using get_post()

Question

In wordpress, I am using :

$posts=get_posts($args)
foreach($posts as $post){
   //do stuff
} 

However, when there is no posts I get

undefined offset: 0 in C:\\xampp\\htdocs\\wrDTC\\wp-includes\\query.php on line 2859

I have tried using if($posts){} but the notice still comes up. How do I prevent this notice other than turning off error messages in php?

Answer 1

use Something like this...

  if(!empty($args) && count($args)>0){
    $posts=get_posts($args)
    foreach($posts as $post){
       //do stuff
    } 
    }

You can't simply use the $posts as name of vars in the loop.

"$posts" is used in the query of wordpress as global and must be an array.

If you choose to name you var $posts, this result into an undefined offset 0 because your $posts do not have offset 0. remember, you just reset it.

Answer 3

try defining the offset in your $args ie ('offset' => 1) and instead of using the usual {} try using hooks and "endforeach;"

My foreach statements in wordpress dev are structured like:

<?php foreach($myPosts as $post) : setup_postdata($post) ?>

      <?php the_title(); ?>
      <?php the_content(); ?>
      // etc
      <?php endforeach; ?>
