Using acf_form() to create and update custom post types with custom taxonomies. I use four acf_fields to select the taxonomies, and then use acf/save_post to update them. It works when I update the posts but doesn’t work with new posts.
I thought that maybe I was triggering before ACF saves the field values, but even with priority 999 get_field returns false.
acf_form code for new posts:
$gids = array();
$groups = get_posts('post_type=acf&posts_per_page=-1');
if ($groups){
foreach ($groups as $group){
$post_custom = get_post_custom($group->ID);
$rules = unserialize($post_custom['rule'][0]);
if ($rules['param'] == 'post_type' && $rules['value'] == 'bem-cultural'){
$gids[] = $group->ID;
}
}
}
acf_form(array(
'post_id' => 'new',
'field_groups' => $gids,
'submit_value' => 'Enviar'
));
functions.php
//savetaxonomies
function brg_save_taxonomies( $post_id ) {
//get_fields
$cats = array();
$cids = array();
$cats[] = get_field('categoria'); //returns false with new posts. works on updates
$cats[] = get_field('subcategoria'); //returns false with new posts. works on updates
$cids[] = get_field('cidade'); //returns false with new posts. works on updates
$cids[] = get_field('região'); //returns false with new posts. works on updates
$cat_ids = array_map( 'intval', $cats );
$cat_ids = array_unique( $cat_ids );
$term_taxonomy_ids = wp_set_object_terms( $post_id, $cat_ids, 'categoria-bem-cultural' );
$cid_ids = array_map( 'intval', $cids );
$cid_ids = array_unique( $cid_ids );
$term_taxonomy_ids = wp_set_object_terms( $post_id, $cid_ids, 'cidade' );
}
// priority 20 to run after ACF saves data
add_action('acf/save_post', 'brg_save_taxonomies', 20);
//new posts
function brg_pre_save_post( $post_id ) {
// check if this is to be a new post
if( $post_id != 'new' )
{
return $post_id;
}
//gets custom title
$title = '';
foreach ($_POST['fields'] as $key => $value){
$fobj = get_field_object($key);
if ($fobj['label'] == 'Nome do Bem'){
$title = $value;
}
}
// Create a new post
$post = array(
'post_status' => 'publish',
'post_title' => $title,
'post_type' => 'bem-cultural',
);
// insert the post
$post_id = wp_insert_post( $post );
// update $_POST['return']
$_POST['return'] = home_url() . '?p=' . $post_id;
// return the new ID
return $post_id;
}
add_filter('acf/pre_save_post' , 'brg_pre_save_post' );
If I save the taxonomies inside pre_save_post it works, but the acf/save_post wipe them out. As a workaround, I’m checking if the post is old or new before updating in acf/save_post, but I would like to avoid using this patch.
