i am using code igniter in the website i'm working on and i need php combined with any language to do:
for example i have a dropdown list named states that takes its values from a data base, and i have another dropdown list named cities that has its values from a database also.
when i click on a state the city dropdown list should show the cities in that state only.
i read that i need ajax...which i dont know hot to use
any hints or scripts?
