function sort_checkbox( $field ) {
	
	$field = sort($field["choices"]);
	
    return $field;
    
}

add_filter('acf/load_field/key=field_5d4164d40898f', 'sort_checkbox');

But it doesn’t work?

Hi Tringwebdesign,

I think it’s not working because you try to save the $field[“choices”] in $field, try this :

function sort_checkbox( $field ) {
	$field["choices"] = sort($field["choices"]);
	return $field;   
}
add_filter('acf/load_field/key=field_5d4164d40898f', 'sort_checkbox');

I assume the sort method you use is correct, it’s may not.

Not working but one step closer, thank you.

Maybe the sort method doesn’t work … You can’t check here how to use the sort method.

I assume you have text choices so you may have to add a sort flag (See in the link).

I think you should use ksort – it sorts the array by key.
Also you can’t save it to the $field[‘choices’], because this function does it by pointers. Just do it like this:

function sort_checkbox( $field ) {
	ksort($field["choices"]);
	return $field;   
}

add_filter('acf/load_field/key=field_5d4164d40898f', 'sort_checkbox');
