I don’t know how the pods framework works so I can’t tell you how to set the value but I can get you started.
First, don’t store your entire “machine %n
” string. The “machine” part it going to be the same for all entries, correct? Then just save the “%n
“.
Now, when you need to add a new post …
function get_next_reference_number() {
global $wpdb;
$ref = $wpdb->get_var("SELECT MAX(meta_value) FROM {$wpdb->postmeta} WHERE meta_key = 'reference_number'");
return (!empty($ref)) ? $ref + 1 : 1;
}
Hopefully you can work that into your Pods code.
