Hi there,

is it possible to create an “placeholder” field in which can be values written?

For example:
I want to create some “ranking” fields..
1. Design
2. Speed

now i can use these fields to create an average ranking like:

$field_1 = get_field('design');
$field_2 = get_field('speed');
$total = ($field_1 + $field_2) / 2;

But i want to use a ACF in the backend for the $total variable.

I hope it is conceivable what I mean.

THX 🙂

Yes, something like this can be done.

You have 2 choices. The first is the easiest. Us an acf/load_value filter on your place holder field. Get the values from the other 2 fields, if they exists, an do the calculation and return the result.

The second would be to create custom JavaScript to populate the field without doing a page load. You’d need to do some more research on this. You can start here: http://www.advancedcustomfields.com/resources/adding-custom-javascript-fields/
