Filter for WordPress option

[sebastian.pisula]

I can add filter to option. Good idea to ACF Page options.

add_filter( 'option', 'acf_options_page' );

function acf_options_page( $value, $option, $default ) {
	if ( $default == false ) {
		return get_field( $option, 'option' );
	}

	return $value;
}


get_option( 'field_from_acf' );

Hi @sebastian.pisula, thanks for the ticket.

There are three filters already in get_option():

• pre_option_* to filter the value before it is retrieved and return early.
• default_option_* to filter the default value.
• option_* to filter the resulting value.

They should work for your use case too. Could you elaborate on why you think a new filter is needed?

I can see a use for a general catch-all options filter for handling $default value, when an option isn't set otherwise, for more complicated usage. But I wasn't aware ACF stored options in a *different* place or named differently.

Anyways, it sounds like ACF itself has enough information about the option fields registered to make use of default_option_* filters itself in this case as core stands now. A filter like this should probably be named default_option too, and it would allow for one default callback being able to be set instead of setting 25-30+ callbacks, one for each default_option_*.

This applies to Pods too, as we allow traversal for relationship fields. We allow options to be created too, which store the relationship item ID, but having the ability to use interesting use cases like $color_id = get_option( 'featured_friend.favorite_color.ID' ); could be made possible within about 6-10 lines of code in Pods if this filter were available.

So overall, I'm in favor of a default option catch-all filter, I'm not in favor of the name option, and I'm confused why ACF would store an option value differently from an option name.

At least in default_option, it wouldn't be run on every option call, so that's a mark towards inclusion of this particular option hook.

I am almost positive that what is being proposed is already possible?

As per comments above. The existing filters mean this is already possible.
