Custom Fields Don't Insert After Publishing

This is how it looks when I try to add a new post:

Screenshot

This is the code I use in functions.php:

add_post_meta($post_id, 'Post Thumbnail', $post_thumb, true) or update_post_meta($post_id, 'Post Thumbnail', $post_thumb);

add_post_meta($post_id, 'Project URL', $url, true) or update_post_meta($post_id, 'Project URL', $url);

add_post_meta($post_id, 'Project Thumbnail', $thumb, true) or update_post_meta($post_id, 'Project Thumbnail', $thumb);

I complete the fields, hit update then publish and when the page is refreshed, the fields disappear. I have to go down to the dropdown select them and add them again to make it work. Any ideas?

Also, is there any other way to insert post meta keys to the custom field dropdown when I install the theme without showing the custom fields when adding a new post? This would be a better solution considering that users don't need to use all 3 fields in one post.

You should use this structure, more effect...
```
$valiable = 'demo';

/**

*** Variable also can be a array or object

**/



$key = 'somekey';

/**

*** If key will have underscore (_) before, it will he hidden from edittion via custom meta fields

** _hideme as sample

** done use space for post meta_key

**/





if (!update_post_meta($post_id, $key, $valiable)){

	add_post_meta($post_id, $key, $valiable);

}	
```
you also can fix you metakeys to

post_thumbnail
project_thumbnail
project_url

  Nope, the problem is still there. I used a fresh WP install.
  
  This is how it looks before I click 'publish'. And this is after the page is refreshed.

  hm... the data alsready in your db. (that's why you see the meta fields in select)
  
  have you disable revisions in wp-config.php?
```
define('WP_POST_REVISIONS', false);
```

  The data that I enter in the custom fields in the before screenshot aren't being inserted into the database.
  
  I have to go back after I hit publish to select each on again for it to work.

I think it is costly to avoid good plugins, because you will basically be re-inventing the wheel and wasting time to achieve the same thing. Magic fields is another good custom fields plugin.

You should really consider using one as reference if you plan on writing your own.
