I try to update an ACF field (taxonomy type) for a post with update_field but it does not work. This updates the wp_postmeta table but not the relationship between the post and taxonomy (wp_term_relationships).
How to solve this problem ?
update_field() function won’t update the post taxonomy. To do that, you need to set the taxonomy by using the
wp_set_post_terms() function. This page should give you more idea about it: https://codex.wordpress.org/Function_Reference/wp_set_post_terms.
I hope this helps 🙂
i use wp_set_object_terms for it s a custom posttype and custom tax, but it doesnt work. May be i cant call this function in the acf/save_post action ?
update_field( ‘field_56618811a093f’, 18, $postID ); = OK
$term_taxonomy_ids = wp_set_object_terms( $postID, 18, ‘my_taxonomy’); = doesnt work
I tried several ways but none worked. With the slug, the id, … yet updat_field lines work
here is my code, see // WP SET TERM OBJECT DOESNT WORK (line 57)
here is a zip
I’ve just tested
wp_set_object_terms() function with the
acf/save_post hook, and it’s working correctly. But please keep in mind that I modified the code so it’s working on my installation.
Could you please make sure that the variables have the correct values? Could you please debug it like this:
echo "\noeuvre\n:"; var_dump( $oeuvre ); echo "\nterm_id\n:"; var_dump( $term_id );
Also, could you please add the variable manually like this:
$term_taxonomy_ids = wp_set_object_terms( 99, 123, 'statut_pret');
Where “99” is the post ID and “123” is the term ID.
in fact , the problem was the $oeuvre variable, for it is an array
i had to write :
$term_taxonomy_ids = wp_set_object_terms( $oeuvre->ID, $term_id, ‘statut_oeuvre’);
$term_taxonomy_ids = wp_set_object_terms( $oeuvre, $term_id, ‘statut_oeuvre’);
Thanks for help
