The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Drop Down Box Selection Populates Another Drop Down Box

Asked by joedunn in PHP and Databases, JavaScript, Web Development

Tags: html, javascript, php, ajax

The effect I want to create is really simple, however, doing it is not, at least for me.

I have a form on a page.  When a selection in combo box 1 is made it populates combo box number 2 then 3 then 4.

Like this...

Box 1 - Country
Box 2 - State
Box 3 - City
Box 4 - Zip Code


So for this example let assume I make the following choices:

Box 1:  United States (All countries would be displayed in Box 1)
Box 2:  Idaho (All 50 US States would have been available
Box 3:  Boise (A list of cities that I wanted for Idaho would be here)
Box 4:  83705 (a List of available zip codes for Boise, ID, USA)

I know I have to supply the lists for each box, that is easy, I have the data.  

#1.  How can I do this?
#2.  Is it possible to do this via a connection to a DB where each table in the DB contains information for a different field?  That would be the best but I'll take whatever I can get help with.

Thanks
