Ugh, I’ve been researching for hours now and just can’t get this to work. I have a custom post type called “Equipment”. I made a page to allow a user to create a new post from the frontend. This page has an acf_form on it. I don’t want to use ‘post_title’ => true, I need to use a custom field to set the post title.
I was able to use acf/save_post to correctly update the title and slug when I update a post from the frontend using an acf_form, but not when I initially create the post. This is the code I used:
On my page template for “example.com/create-equipment”:
<form id="equipment" class="acf-form" action="" method="post">
<?php acf_form( array(
'id' => 'create-equipment',
'post_id' => 'new_post',
'new_post' => array(
'post_status' => 'publish',
'post_type' => 'hb_equipment',
),
'fields' => array(
'equipment-name',
'equipment-type',
'equipment-cost_number',
'equipment-weight',
'equipment-description',
),
'form' => false,
'honeypot' => false,
'return' => '%post_url%',
)); ?>
<div class="acf-form-submit">
<input class="acf-button button button-primary button-large" type="submit" value="Create">
</div>
</form>
In functions.php:
function dwp_save_post( $post_id ) {
$new_title = get_field('equipment-name', $post_id);
$new_slug = $post_id . '-' . $new_title;
$new_post = array(
'ID' => $post_id,
'post_title' => $new_title,
'post_name' => $new_slug,
);
wp_update_post( $new_post );
}
add_action('acf/save_post', 'dwp_save_post', 20);
That correctly sets my urls to “example.com/equipment/123-post-title”, but only when I’m updating an existing post, not when creating a brand new one.
I’ve also tried using acf/pre_save_post but I wasn’t able to get it to do anything at all.
