Hello everyone I am PHP Developer and developing website .in that i used Google map with the facility of select state and city. for select state and city i put two drop down.so now my problem is when i select state then i can not get value of city and both time whenever use select state and city i refresh the page and so after refreshing the page the value i got is incorrect and does not match the state with city...

i clarify again

• Step 1:- select state (here page will refresh and then i will get value)
• Step 2:- select city (here also will refresh and then i will get value))

problem :- on the base getting state id and city id i fire the query but result will unknown b'cz city id that does not in selected state actually that city is there
