Is there a way to update multiples fields from a given post without the use of update_field inside a loop ?
The only way I’ve managed to update an array of fields is like this :
$post_id = 1234;
foreach ($acf_fields as $key => $value) {
update_field($key, $value, $post_id);
}
But it’s a performance nightmare.
No there isn’t. ACF uses use update_post_meta() or update_metadata(). Every update requires at least 2 db queries and sometimes 3. This means that it can take 4 to 6 queries to update a single ACF field.
WP does not supply any way to update more than a single meta value at a time in a single query.
There is a way, but it would require accessing the database directly and constructing the correct SQL query to do multiple updates or inserts to the correct table in a single query. You would also need to account for both the field value and the acf field reference value as well.
Okay, thanks for the clear answer.
