Hi i have add into my post type “orders” a select with 4 choices.

When someone is writting through our form, it is creating a new post type with the default select (select value1).

When an admin is adding info into the post type that is a private post he is selecting an another choices for example (select value2, select value3, select value4) then save it.

I want to display into the admin wordpress the numbers that the post has been changed.

For example:

I change the status to select value2 then i save. I return 2 days later and i change the select to value4 and save it. We will see into then admin colum “Numbers Change” : 2

A plus will be to be able to get the timestamp between those changed.

Is it possible i’m kind lost. Thanks you very much for your help.

I think i my found a solution. I have activate post revision for my post type.

But now i only want that revision is saved if this acf field is changed and saved.

Any idea ?

Thanks in advance

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 🙂
