How to dynamically set specific field read only

Hi,
i’d like to prevent user from modifying a field value, once the post has been published.

=> is there any action / filter / function to dynamically set this field to read-only in wp-admin, “if post_status == ‘publish’ && current_user_can(“publisher”) ?

Thanks for your help
Baptiste

Hi Baptiste,

Yes, you can use the acf/load_field filter to modify the field object. The code would look something like this:

function my_load_field($field) {

	if(...) {
		$field['readonly'] = 1;
	}
	
	return $field;
}

add_filter("acf/load_field", "my_load_field");

For more info, check out the documentation of the filter. Here is the link: http://www.advancedcustomfields.com/resources/acfload_field/

Hi —

I have found that setting readonly to 1 works for text fields, but not for fields of other types — if there’s a widget, the widget still functions (*and* changed values are saved). In my case I have both a select of users and a radio dialog box.

Currently I am getting around this by converting each field to a text field in the load_field filter, plus setting it to readonly.

But this feels very hacky and fragile — I already ran into a problem where I had switched between saving the label or the value of a choice and it broke.

So I would like to add my vote for official support of the ability to dynamically set a field to readonly, and have that work for widgets as well.
