I expects the output in when ever select country in country drop down automatically shows the selected country related states and state related city's in drop down.
But the actual output show the only country in country's drop down, whenever the select the country in country's drop down , the country related state are not displayed in the state drop down.
the database table's details are: country,state and city.
country table:
1.country_id(pk)
2.Country_name.
state table:
1.state_id (pk).
2.state_name.
3.country_id (fk).
city table:
1.city_id (pk).
2.city_name.
3.state_id (fk).
thous are the database table fields.
I am also try the normally cascading drop down its work, but i am trying to fetch the values from database, it's not working .
It's showing the only the country's values ,the country related states and state related city's not fetching .
In database three tables are the relationship using the primary key and foreign key.
But shows the only country's values in the country drop down.
I don't know what I am doing wrong here so can you help me?
I want to create a cascading drop-down menu and I can't see what I am doing wrong. I've tried everything. I am just out of ideas.
please provide the solution.
Thank you
