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!

PHP Security - How do protect my chart.

Asked by lwfuk in PHP Scripting Language, Miscellaneous Security, Networking Security Vulnerabilities

Tags: php

I'm looking for ideas.

Server = Linux.

Problem

1. I have a form that posts back to itself

2. The form has a JPGraph chart

3. After post back the src of an image on the form is set to the JPGraph chart with the post parameters echoed like this:
www.host.com/jp-chart.php?var1=12&var2=14

4. The application operates in a members area.

5. How can I protect the chart so that non-members cannot access the chart?

As the application stands anybody could right click and view the path and variables required to make the chart work therefore bypassing the login process.
