Hello,
For a sports licensing system I would like to have a “number” field that auto-increments each new creation of the custom post.
I think I should use something like update_field but it would really help me to get help 🙂
thank you in advance
Maybe a little help ?
Thank you in advance!
There really isn’t a way to do this simply.
There are a couple of choices.
The is to create an acf/save_post filter https://www.advancedcustomfields.com/resources/acf-save_post/. In this filter get the value of the field and save it as an option https://developer.wordpress.org/reference/functions/update_option/. Then create an acf/load_field filter https://www.advancedcustomfields.com/resources/acf-load_field/ and set the default value for the field based on the option.
Second choice. Create an acf/load_field filter. In this filter you do a query to get the posts of the post type. Order DESC by the custom field, limit the posts returned to only get 1 post. Get the value of the field on this one post and set the default value of the field based on this value.
Either has it’s pros and cons
Thank you very much for your leads, I found a solution that seems to work well :
add_option('ebo_dernier_num_club','3005','','no');
function ebo_renseigne_num_affiliation($value, $post_id, $field) {
if (! $value && get_post_type($post_id)=='club_type') {
$last_num = (int) get_option('ebo_dernier_num_club', '3000');
$last_num++;
update_option('ebo_dernier_num_club', $last_num);
$value = $last_num;
}
return $value;
}
add_filter('acf/update_value/name=numero_affiliation', 'ebo_renseigne_num_affiliation', 10, 3);
I also wanted to make the field uneditable with this function:
function msk_acf_disable_field($field) {
$field['disabled'] = true;
return $field;
}
add_filter('acf/load_field/name=numero_affiliation', 'msk_acf_disable_field');
But that does not seem to be compatible.
