The reason I ask is because I am developing some code which needs to problematically save some custom field values created by custom press. It works fine using e.g.
update_post_meta($post->ID, '_ct_text_4df33e5650246', true)
But I can see that by having to use '_ct_text_4df33e5650246' to reference the field means that if I was to re-create the custom field on my live Wordpress install, the ID will be different, so my code will not be portable.
Is it possible to use the name of the custom field instead?
e.g. update_post_meta($post->ID, 'website', true)
