Custom fields allow adding extra content areas and customizing page layouts. A document summarizes using custom fields to design film catalogue pages with distinct sections like title, description, credits. It explains creating a page template, planning custom field "buckets", entering field data, and coding fields into the template. Plugins like Advanced Custom Fields simplify field creation and entry. The document encourages experimenting with custom fields and combining skills with custom post types.

16. What exactly ARE custom fields?
“Key/Value Pairs”
Think of custom fields as:
– he ability to create your own post template tags.
t
(Make some room, the_content!)
– mpty buckets in which you can store any piece of
e
information that you might want to retrieve later.

HOORAY!
Our final film page
layout works.
Now, how can we
make it better and
more flexible?

25. Extra Tip!
B
how to
Customize
Add conditional code to hide or
display a whole content section
Before:
h4 class = creditsAwards/h4
?php echo get_post_meta($post-ID, 'film-awards', true); ?
div class = doubleline/div

26. Extra Tip!
B

?php

h4 class = creditsAwards/h4
div class = doubleline/div
?php echo get_post_meta($post-ID, 'film-awards', true); ?
?php } else { ?
?php } ?

27. Extra tip!
B
Add ‘else’ to publish default info
if no new value exists
how to
Customize
h4 class = creditsAwards/h4
div class = doubleline/div
?php
if ( get_post_meta($post-ID, 'film-awards', true) ) { ?
?php echo get_post_meta($post-ID, 'film-awards', true); ?
?php } else { ?
pNo awards yet. Please petition a href =
http://www.oscars.org/the Oscar committee/a./p
?php } ?

28. But what about posts?
The layout concepts are the same when adapting posts, but post
templates are not created the same way as page templates. The
difference is that the syntax for ‘single-{typename}.php is reserved
for Custom Post Types.
Options:
— dapt existing templates by adding custom code to
a
single.php, index.php, archive.php, and category.php
— dd conditional code to current template files, so certain
a
custom fields display for certain categories
— se one of the many post template plugins to
u
recognize and apply your post templates:
