Is there a wildcard/catchall filter hook?

Question

I would like to filter all the options values, but the option filters are option specific. Is there a way I could do something like

add_filter('pre_option_*', 'my_check');

?

Answer 1

I've tried the same thing and was able to hook into the pre_option_ filter by using all as filter.

add_filter('all', 'pre_option_',1,3);

function pre_option_($actionHook,$bool=false,$option_name)
{
    if(strpos($actionHook,'pre_option_') === FALSE){
        return $bool;
    }
}

I suppose you could use wp_load_alloptions() and add a filter for each:

foreach ( array_keys( wp_load_alloptions() ) as $option ) {
    add_filter( 'pre_option_' . $option, function ( $pre ) use ( $option ) {
        // blah
        return $pre;
    } );
}
