This post shows three ways to display and order posts by meta value num in dl dt dd h4 and p.it retrieve some values of custom fields,coding by feilong on Nov.6,2010.this post url is http://feilong.org/three-ways-display-order-posts-meta-value.

In order to use these wordpress snippets,you should use wp-postviews plugin first.

And of course,these snippets requires the functon get_attchfirst() to display the first pic of the post

//In functions.php: 
//get the first attachment picture of a post in or out of the loop feilong.org 20101105
function get_attchfirst($postid,$size = 'medium') {
$args = array(
	'order'          => 'ASC',
	'post_type'      => 'attachment',
	'post_parent'    => $postid,
	'post_mime_type' => 'image',
	'post_status'    => null,
	'numberposts'    => 1,
);$attachments = get_posts($args);if ($attachments) {
$attchfirst = wp_get_attachment_image($attachments[0]->ID, $size, false, false);
} else {
$attchfirst = '

ONE WAY:directly write template tags in your wordpress theme,this is the basic way for beginers of wordpress themes







ID,'thumbnail'); ?>




$ID, 'price', true); ?> $ID, 'new_price', true); ?>







TWO WAY: query_posts, turn the template tags above into a function in order to reuse it in wordpress themes.


'."\n";
echo '
'.get_attchfirst($post->ID,$size).'
'."\n";
echo '
';
if(function_exists('the_views')) { the_views(); } //need wp-postviews plugin
the_title();
echo '
'."\n";
echo '
'.$curr.get_post_meta($post->ID, 'price', true).' '.$curr.get_post_meta($post->ID, 'new_price', true).'
'."\n";
echo ''."\n";
endwhile; else : echo 'no posts';endif; wp_reset_query();
}

//Sample usage: somewhere in your wordpress theme
dlh4p_list ('large','￥',1,3,'meta_value_num','DESC','views');

?>



THREE WAY:get_posts, turn the template tags into function,just another coding.


'.get_attchfirst($post->ID,$size)."
\n";
echo '
';
if(function_exists('the_views')) { the_views(); }
the_title();
echo '
'.$curr.get_post_meta($post->ID, 'price', true).' '.$curr.get_post_meta($post->ID, 'new_price', true)."
\n";
endforeach;wp_reset_query();
}

//Sample usage: somewhere in your wordpress theme
specialbox ('medium','%',1,3,'meta_value_num','ASC','views');

?>
