For giving you idea in this topic i need the circuit diagram of the voltage divider circuit you used. coding logic is correct. Use diodes and voltage divider to ac voltage to dc voltage. Because Pic microcontroller can only read the dc voltage logics.
you can refer to this page for transformerless ac to dc convertion.
Note: Ac live Voltage will be found all over the circuit so be safe while doing these type of projects.
