If it can be done in PHP, it can probably be done in Wappler

that's why i like wappler even with the shortcoming on some features. if its not there just add it since its PHP and not some weird language

my only complain that you are mixing PHP and JS and you know users can change any client side vars you assign.
it will be bulletproof if it was all on the server.
this is way i requested this feature
