   Hi - I am working on an 'Artwork Info' meta box created with the WPAlchemy MetaBox PHP Class. In my child theme's functions.php I am using the following to loop through and print the field values:

   // Print the meta box data - called in display_artwork_info()
   function print_meta($val){
   	global $artworkinfo_metabox;
   	if($val != '') {
   		$artworkinfo_metabox->the_value($val);
   		echo "br";
   	}
   }
   
   // Display Artwork Info fields in post
   function display_artwork_info() {
   
   	global $artworkinfo_metabox;
   	global $post;
   	global $terms;
   
   	$values = array('title','collabs','dimen','additional');
   	$artworkinfo_metabox->the_meta();
   
   	echo the_content();
   	echo '<div id="artwork-meta">';
   
   	// Loop through the meta values
   	foreach ($values as $val){
   		print_meta($val);
   	}
   
   	echo '</div>';
   } 
   
   add_action('thematic_post', 'display_artwork_info');

   This all works well, except if one or all of the fields are empty, the line breaks still echo. With one field missing, the HTML comes out like this:

   <div id="artwork-meta">
         Title
    br  <!-- no value but break still echoes -->
    br
          Dimensions
    br
          Additional Info
    br   <!-- also shouldn't be there... -->
   </div>

   Any ideas? Thanks in advance.

   P.S. I'm writing br instead of the actual tag because the forum applies it as a tag.

   gosh i love alchemy. it is freaking brilliant.

   i'm not sure why you need the extra print_meta function?

   if you set up a repeating field, like have_fields or have_fields_and_multi you can just loop through it using the wpalchemy object. here's a sample of something from i posted in his comments (that's me Kathy)

   if ($featured_metabox->have_value('slides')) {
   
   while($featured_metabox->have_fields('slides')){
   if($featured_metabox->is_first()){ echo '1st bacon';}
   $featured_metabox->the_value('url');
   if($featured_metabox->is_last()){ echo 'last bacon'; }
   }
   } else { echo "you borked it"; }

   I was using print_meta() to print the break because it wouldn't print in the loop for some reason. I'd like the fields to echo like this - a line break after each printed value, not just first/last:

   Title
   Medium
   Dimensions
   Collaborators
   Additional info

   In your function, 'slides' is the title of WPAlchemy_MetaBox() and 'url' is the name of a field, right? I think there may be a gap in my understanding somewhere. I shortened my loop to this, which prints everything but not the break:
   

   $mb->the_meta();
   $values = array('title','collabs','dimen','additional');
   
   foreach ($values as $val) {
   		while ($mb->the_value($val) != ''){
   			$mb->the_value($val);
   			echo 'break';
   		}
   }

   So, the output is something like

   The TitleThe MediumThe DimensionsThe CollaboratorsAdditional info

   So, I'd made the print_meta() function to compensate for that, but it always printed the break instead of conditionally.

   Thanks a lot for your help!
