How to Add Custom Fields to a Custom Post Type?

Question

Ok, so I have registered a few custom post types and a few taxonomies. Now, for the life of me, I cannot figure out the code I need to add a Custom Field to my Custom Post Type.

I need a drop down and a single line text area. But I also need to have separate fields for post types. So, say post type one has 3 fields and post type 2 has 4 fields but the fields are different.

Any tips would help I have looked at the codex and found something but cannot make sense of what I need to add to my functions.php file

Answer 1

This is probably more complicated than you think, I would look into using a plugin, specifically these two:

• WPAlchemy http://www.farinspace.com/wpalchemy-metabox/
• Custom Field http://wordpress.org/extend/plugins/custom-field-template/

If you want to write your own , here are some decent tutorials:

Answer 2

I highly recommend you these (free) three plugins: "More Types", "More Taxonomies" and "More Fields" plugins, each one for creating custom post types, custom taxonomies and custom fields, respectively. Just clicking, draging and dropping, no code needed.

Answer 3

add

'supports' => array( 'title', 'editor', 'excerpt', 'thumbnail', 'custom-fields', 'revisions' ),

to your args array while registering the custom post type.
