Just popping in to provide this information on hashing/unhashing because the link to andrewwho.nl is no longer.
function dec_enc($action, $string) {
$output = false;
$encrypt_method = "AES-256-CBC";
$secret_key = 'This is my secret key';
$secret_iv = 'This is my secret iv';
// hash
$key = hash('sha256', $secret_key);
// iv - encrypt method AES-256-CBC expects 16 bytes - else you will get a warning
$iv = substr(hash('sha256', $secret_iv), 0, 16);
if( $action == 'encrypt' ) {
$output = openssl_encrypt($string, $encrypt_method, $key, 0, $iv);
$output = base64_encode($output);
}
else if( $action == 'decrypt' ){
$output = openssl_decrypt(base64_decode($string), $encrypt_method, $key, 0, $iv);
}
return $output;
}

Thank you for your swift reply!
It’s unfortunate that the taxonomy field is not modular in the way I expected it to be since it would’ve made sense for the fields to function in the way I expected. Eespecially since how the documentation was worded, there wasn’t any reason for me to believe it wouldn’t work.
Thank you! I’ll consider building an acf/save_post action after a think about the effort/reward levels. It might just be something I include in the documentation for the editors and if they wonder why something isn’t showing up, then they’ll email me lol
I’m trying to do exactly this, and I’d love to know what approach you took where you didn’t need this anymore!
