   is there any way to have custom post meta+html not output if the box is blank?

   I'm bit of a php newbie and have been reading up on it, but i have tried 'undefined' as well as 'null'. Also tried: if (isset($embed)), but probably did it wrong? None seem to work.

   if ($embed != null) {
   	echo '<div id="slide"><iframe title="YouTube video player" width="424" height="348" src="http://www.youtube.com/embed/';
   	echo get_post_meta($post->ID, "embed", true);
           echo '" frameborder="0" allowfullscreen></iframe></div>';
   }

   here is portion of functions.php that has the embed code for custom post meta:
   

   add_action('init', 'package_register');
   
   function package_register() {
   	$args = array(
       	'label' => __('packages'),
       	'singular_label' => __('package'),
       	'public' => true,
       	'show_ui' => true,
       	'capability_type' => 'post',
       	'hierarchical' => false,
       	'rewrite' => true,
       	'supports' => array('title', 'editor', 'thumbnail')
       );
   
   	register_post_type( 'package' , $args );
   }
   	add_action("admin_init", "admin_init");
   	add_action('save_post', 'save_embed');
   
   	function admin_init(){
   		add_meta_box("prodInfo-meta", "package Options", "meta_options", "package", "side", "low");
   	}
   
   	function meta_options(){
   		global $post;
   		$custom = get_post_custom($post->ID);
   		$embed = $custom["embed"][0];
   		echo '<img src="http://www.address.com/wp-content/themes/slideshow/images/vimeo.png"><br /><label>embed:</label><input type="text" name="embed" value="'. $embed .'" />';
   	}
   
   function save_embed(){
   	if(isset($_POST["date"]))
   	update_post_meta($post->ID, “horario”, $_POST["date"]);
   	global $post;
   	update_post_meta($post->ID, "embed", $_POST["embed"]);
   }
   // custom table columns
   register_taxonomy("catalog", array("package"), array("hierarchical" => true, "label" => "Catalogs", "singular_label" => "Catalog", "rewrite" => true));

   also anyone know if custom post meta can store html? seem to have some issues with it storing html, but alpha-numeric numbers seem to work fine.

   If what you are trying to do is only display the iframe when there is a value in the custom field you can try it like this:

   $embed = get_post_meta($post->ID, "embed", true);
   if ($embed) {
   	echo '<div id="slide"><iframe title="YouTube video player" width="424" height="348" src="http://www.youtube.com/embed/';
   	echo $embed;
           echo '" frameborder="0" allowfullscreen></iframe></div>';
   }

   That code assumes you have not already created a variable named $embed before this routine. If you have this code will overwrite its value.
