Hi @debosseta
If you want to use post revision, I suggest you get in touch with WordPress community instead for better support.
Another method would be using a number field that will hold the total count. Then you can update the total count by using the acf/save_post hook like this:
function my_acf_save_post( $post_id ) {
if( get_post_type($post_id) == 'orders' ){
// Set the required field name and keys
$select_field_name = 'select_field_name';
$select_field_key = 'field_1234567890abc';
$number_field_name = 'number_field_name';
$number_field_key = 'field_abcdefghij123';
// Get the old data from database and the new data (posted data)
$old_select_value = get_field($select_field_name, $post_id);
$new_select_value = $_POST[$select_field_key];
// If the value changed
if( $old_select_value != $new_select_value ){
// Get the total count from the database
$old_count = get_field($number_field_name, $post_id);
// Change the posted data to make sure it's correct
// This will be saved automatically later
$_POST[$number_field_key] = $old_count + 1;
}
}
}
// run before ACF saves the $_POST['acf'] data
add_action('acf/save_post', 'my_acf_save_post', 1);
You can also disable the field by using CSS so the value can’t be edited from the backend.
If you want to have timestamps, I suggest you use the repeater field instead.
I hope this helps 🙂
