[wp-hackers] Testing for existence of WP_Query results

[Ashok Padda]

Hi Ade,

Please try using if($recent->have_posts()) instead of if($recent)

Following code worked for me
------------------------------x------------------------------
$recent = new WP_Query('category_name=special_category');
  if ($recent->have_posts()) :
    while($recent->have_posts()) : $recent->the_post();
      the_content();
    endwhile;
  else :
    echo 'No posts are posted in the category';
  endif;
------------------------------x------------------------------
