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!

Arrays  -bit confused

Asked by abenbow in PHP Scripting Language

ok, Arrays

for some reason arrays have always got the better of me so I normally come up with away around using them. Unfortunatley I am up against a problem and the only solution I can see is to use an array.

So

I need to keep a seperate track of products and categories that a shopper has in their cart.

I need to use a session variable to do it.

and, because I have no idea how many products or categories there will be, I need to use an array.

can I have something like

$_SESSION['cat_check'] = array();  ?

each part of the array has an ID number (i assume), the category id then the product id?

can I check for the existance of a product id (how) if its not there how do I add the category id and product id to the end of the array?

also what I want is a product id once but that may lead to a category id being in more than once - can I check how many times a category id is in there?

If it needs more points then I'm happy to sort that.

Just to clarify, I don't want to/can't use a database table so please don't suggest that as a possible solution :)
