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!

Pass form values in coldfusion

Asked by panosms in ColdFusion Studio, ColdFusion Application Server

Hello experts.
I need help to decide wich method i should use to pass form values from two search pages (two search forms) to one result page and one detailpage.
To build this i have used Url variables.
On the result page i have two link to the searchpage1 Or 2 depending on a Url variable and using
<cfswitch and cfcase.
The first link is :New search
And the second  to Edit the search fields using the url variables:
I also handle the number of records with a form.
And the function sort by that works with url variables too.

I have also  alink to the detail page.
On the detail page are these two links for new search and edit search and a third one that goes to the result page(not back)

The question is how can i pass the search values from page to another page.
f.e if i choose 20 for number of records than i loose the search values in URl.If i add #CGI.Query_String# to URL i get more than once the value for the records.
And than from the result page to the detail and than back how can i pass the values back.
Do i have to use Form variables instead of Url.Do i have to use cookies or session?
Please help.
Here are part of the codes .
