[wp-hackers] get_post_meta in widgets

[Mike Schinkel]

Hi Ash,

I haven't tested this before emailing but I'm pretty sure what you want is:

$rightAdsection = new WP_Query('post_type=page&posts_per_page=1&meta_value=_adsPositionRight&orderby=rand');
foreach($rightAdsection as $ad) {
  $adRight = get_post_meta($ad->ID, '_adright', true);
  if ($adRight)
    echo "it works";
  else
    echo "it doesn't work";
}

HTH.

P.S. If you can use WP3.0 you could create a custom post type "Ad" and then do this instead:

$rightAdsection = new WP_Query('post_type=ad&posts_per_page=1&meta_value=_adsPositionRight&orderby=rand');
foreach($rightAdsection as $ad) {
  $adRight = get_post_meta($ad->ID, '_adright', true);
  if ($adRight)
    echo "it works";
  else
    echo "it doesn't work";
}
