    I have the following code which test categories and display if they have posts with some metadata set or not.

    <?php
$category_counter = count(get_the_category());
$counter = 0;
   foreach((get_the_category()) as $cat)
   {
      $counter++;
      $category_variable = $cat->cat_ID;
      $query_paying_companies = 'cat=' . $category_variable. '&meta_key=field-company-type&meta_value=j';
      query_posts($query_paying_companies); ?>
      <?php if ( have_posts() ) :?>
            <p><?php echo $category_variable;?> - This category is good!</p>
      <?php else: ?>
            <p><?php echo $category_variable;?> - This category is NOT good!</p>
      <?php endif; ?>
<?php wp_reset_query();
  }
?>

    Code works well. What I want – and I do not succeed to complete – is to create and array of “GOOD categories” – only the categories with posts which have this metadata set and then random choose one.

    <?php
$good_categories = array(); //NEW CODE
$category_counter = count(get_the_category());
$counter = 0;
   foreach((get_the_category()) as $cat)
   {
      $counter++;
      $category_variable = $cat->cat_ID;
      $query_paying_companies = 'cat=' . $category_variable. '&meta_key=field-company-type&meta_value=j';
      query_posts($query_paying_companies); ?>
      <?php if ( have_posts() ) :?>
            <p><?php echo $category_variable;?> - This category is good!</p>
<?php $good_categories[] = $category_variable; //NEW CODE ?>
      <?php else: ?>
            <p><?php echo $category_variable;?> - This category is NOT good!</p>
      <?php endif; ?>
<?php wp_reset_query();
  }
?>

    to check your results, you could add this after the code:
    <?php var_dump($good_categories); ?>
