First, click on ‘Screen Options’ at the top of the screen when editing a portfolio post and be sure ‘Custom Fields’ is checked.
If there is no ‘Custom Fields’ option to check, then you need to add the ‘supports’ option for ‘custom-fields’ when you register the post type.
where do I add the supports option?
I didn’t register the post type (don’t even know what it means), this post type was a part of the theme I’m using …
If you are using a free theme, post a link to your site here and someone may be able to look at its code to help. If you are using a paid theme, we cannot examine its code or options, so you should contact the theme supplier.
Here’s the web http://www.zemaraim.com/phantasm
here’s the theme: http://cudazi.com/mono-wordpress-free/
(very WELL documented how to setup, if I might add)
So where do you usually add the support option for custom fields?
Some meta’s are stored in my meta-boxes.php…
In wp-contents/themes/mono/libraries/custom-post-types.php, change line 43 from this:
'supports' => array('title','editor','thumbnail','excerpt','comments')
to this:
'supports' => array('title','editor','thumbnail','excerpt','comments','custom-fields')
You should try to create a Child theme to make your changes. If you do not, all of your changes will be lost if you update your theme.
