This document discusses custom fields and custom post types in WordPress. It provides an example scenario where a food blogger creates a recipes custom post type to display recipes. However, when switching themes later, the recipes disappear since the new theme does not support that custom post type. The document also discusses how to create custom fields to add additional metadata like start/end dates. It covers using plugins like Custom Post Types UI and custom fields plugins to facilitate creating custom content in WordPress.

2. { Overview }
• Custom Fields vs Custom Post Types
• Ways to Customize WordPress
• What is CSS?
• Need more menus?
• Questions

3. { Custom Post Types }
• WordPress stores all page and post data as a
post type.
• There are actually 5 core post types
• Post – Blog Entry
• Page – Static content
• Attachment – Document, Image, Video, etc.
• Revision – Version of a Post or Page
• Menu – Navigation/Menu Item

4. Example Scenario
• Let’s say you have a food blog and you
want to use a custom post type to display
your recipes.
• So you use the awesome code we just
looked at, customized it to represent your
menu offerings. Created categories for
breakfast, lunch, dinner, appetizers,
desserts.

5. Example Scenario
• You have populated your menu with all of
your fantastic recipes.
• Life is good!

6. Example Scenario
• Now let’s say 3 months or 6 months, or maybe
even a whole year goes by, and everything is still
good.
• Then you find the ultimate theme, it’s great, it
looks just like you want your website to look.
• So you install it, then you activate it.
• Then later that day or the next someone emails
and asks where are your recipes, so you tell them
to click on recipes, and they ask WHERE? I’m on
your site and there are no recipes.

7. Example Scenario
• So you go to your site and check. Hmmm no menu….
• Then in 3…2…1.. You panic!

8. { Custom Post Types }
• WordPress allows you to create your own
custom post type.
• Allows you to format content in a particular
way.
• Recipes
• Products (non-ecommerce)
• Frequently Asked Questions
• Etc.

9. { Custom Post Types }
function create_post_type() {
register_post_type( 'acme_product',
array(
'labels' => array(
'name' => __( 'Products' ),
'singular_name' => __( 'Product' )
),
'public' => true,
'has_archive' => true,
)
);
}
add_action( 'init', 'create_post_type' );
Sample code from https://codex.wordpress.org/Post_Types

10. { Custom Post Types }
• Plugins
– Custom Post Types UI
• https://generatewp.com/

11. { Custom Fields }
• The codex defines a custom field as meta-
data, that contains a key/value pair.
• ????

12. { Custom Fields }
• I’ll admit, it’s pretty technical and confusing
• If you keep reading the codex page though, you’ll
see what a key/value pair is.
• Key – the name of the meta-data
• Value – the meta-data
• Example:
– Key: Currently Reading
– Value: Calvin and Hobbes

13. { Custom Fields }
• What can you do with custom fields?
• Announcement features on your website
• First create a custom post type to handle the
announcement content
– Title
– Description
– Photo
• How about an announcement start date?

14. { Custom Fields }
• Create a custom field
– Start Date – built in scheduling of Post
– Display End Date
– Importance
• Using some PHP logic we can display the
content we can make the post
automatically display based upon the
server’s date as well as when to stop.

15. { Custom Fields }
• Using similar PHP logic, we can even
change the CSS class or ID of the
containing element to make the
announcement appear different.

16. { Customize WP }
• WordPress Customizer
• Header Image
• Site Title / Tagline
• Colors
• Additional CSS
• Jetpack Plugin
• Additional CSS option

17. { Customize WP }
• Page Builders
• Gutenberg
• Beaver Builder
• Bold Grid
• Divi
• Custom Field Plugins

18. { Menus – More Menus }
• Adding new menus
• WP Dashboard
• Theme modification
• WP Dashboard
• Appearance -> Menu
• New Menu
• Add Menu Items

19. { Menus – More Menus }
• Theme Function File
– Create Menu Definition
• Creates Menu Position
• Relevant Theme File
– Header.php
– Footer.php
– Sidebar.php, sidebar-_____.php
– Page.php
– Etc…

20. { Menus – More Menus }

'menu' => 'Top Navigation',
'sub_menu' => true
) );
