ACF & PHP-API (WordPress)
Versie door Jeroen Strompf (overleg | bijdragen) op 1 aug 2022 om 10:18 (→Not directly at database level)
How can you automatically manage ACF fields? In particular, fill in, delete and edit?
Not directly at database level
To start with some bad news: While ACF fields are stored in tables wp_options or wp_postmeta, you cannot write directly to these tables to create ACF fields. Then the 'context' is missing, eg a repeater. So you have to do it via an API call.
Two kinds of fields
There seems to be a distinction between two kinds of ACF fields and how to approach them:
- Fields that are associated with specific posts
- Fiels that are not asssociated with specific posts.
Simple example: The home page of a site has ID=7. It has a custom field hero text. How to fetch its value:
<?php
require_once("/var/www/example.com/wp-load.php");
the_field("hero_text",7);
Output:
Eat more chips!
- Function
the_field()displays the value of a field directly - Alternatively, function
get_field() returns the value rather than directly displaying it.
