How can I have the 'Preview Changes' working for custom meta boxes? For instance, I just want to test/ preview some text in a custom meta box but I don't want to save/ update because that post/ page is already gone live.
$post_id = $post->ID; $meta = get_post_meta( get_the_ID(), 'meta_tile1_text', TRUE ); var_dump($meta); ?> <p><?php echo $meta;?> </p>
This only works when I click 'Update' button in the backend. But it does not when I click 'Preview Changes'. I have to save the 'preview' text in order to see it.
Is it possible?
