Add custom fields to post programmatically

Question

I want to create some custom fields that will be able to show to a default wordpress post. I don't want to use the ACF plugin. Is there anyway to do it programmatically?

Thanks

Answer 1

You can use the custom fields included in wordpress

Add a new post and do the following steps:

1. Go to the Options page

2. Select "custom fields" and hit the reload button

3. you now have a custom field in your post edit page at the bottom.

now you can use this custom field in your theme inside the post-loop

<?php while ( have_posts() ) : the post(); ?>

    <?php echo get_post_meta($post->ID, 'featured', true); ?>

<?php endwhile; ?>

You have to replace 'featured' with the name of your custom field.

Once you created a custom field, you can use it in your others post as well.

Hope this is helpful.

This article walks you through creating a very basic, lightweight plugin to add your own meta fields. I'm sure it could be adapted to be used as a standalone function rather than a plugin.

https://metabox.io/how-to-create-custom-meta-boxes-custom-fields-in-wordpress/

Essentially you add your fields using add_meta_box() and setting the post type to post or whatever CPT you like. Update the fields using update_post_meta(). Then display wherever you like using get_post_meta().

add_meta_box

update_post_meta

get_post_meta
