 * Hi!
 * For my custom theme I’m trying to populate a dropdown menu in my meta box with
   my custom taxonomies.
 * I’m using this code to get the custom taxonomies:
    ` $types = get_terms('portfolio-
   category'); $types_array[0] = 'Select all';
 * if ($types) {
    foreach($types as $type) { $types_array[$type->term_id] = $type-
   >name; } }
 * But then I’m getting this error in my WP-admin:
    `Trying to get property of non-
   object`
 * Really, I don’t have any idea what I’m doing wrong??
 * Thanks in advance!

 * What if you try
 *     ```
       if ($types) {
        foreach($types as $type) {
         if ( $type ) {
          $types_array[$type->term_id] = $type->name;
         }
        }
       }
       ```

 * If you have PHP 4/5, try this
 *     ```
       if ($types) {
        foreach($types as $type) {
         if ( is_object( $type ) ) {
          $types_array[$type->term_id] = $type->name;
         }
        }
       }
       ```
