Generating a drop down list from a url (webservice)

tsh9 · August 15, 2010

Hello!

I don't have a lot of experience wih PHP. I'm trying to make a page with two drop down list. The first one is a list of countries generated from an array. When the user selects a country a second drop down list is generated (dynamically) with a list cities from that country using an url: http://www.webservicex.net/globalweather.asmx/GetCitiesByCountry?CountryName=NP (where NP is the country name) and then get the weather info for the city from the selected country using: http://www.webservicex.net/globalweather.asmx/GetWeather?CityName=NV&CountryName=NP (Where NV is for the City name and NP the country name).

I have a few problems

1. I would like to have the selected country/city stay the same even after submitting the request.

2. Have the weather information display after submitting the request.

I have also included the files in a zip file.

Any help would be greatly appreciated !

Thank you.
