Hi, I wrote a module, which utilises field_create_field and field_create_instance. I have my $instance array like below: $instance = array( 'field_name' => 'field_tckn', 'entity_type' => 'user', 'bundle' => 'user', 'label' => t('TCKN'), 'description' => t('Enter your TCKN.'), 'settings' => array( 'user_register_form' => TRUE, ), 'display' => array( 'default' => array( 'label' => 'above', 'type' => 'text_textfield', 'settings' => array( 'size' => 11, ), ), 'full' => array( 'label' => 'above', 'type' => 'text_textfield', 'settings' => array( 'size' => array( '#default_value' => 11, ), ), ), ), 'widget' => array( 'settings' => array( 'size' => 11, 'description' => t('Enter your TCKN.'), ), ), ); The field is attaches to user bundle just fine, but what I would like to is re-use the field in any content type. I can do that too, but I would like to override 'Size of textfield' when I add the field. What am I missing in the above code? Regards, -- mto
