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!

Null or Not Null in MYSQL?

Asked by dsellers99 in MySQL Server, PHP Scripting Language, Macromedia Dreamweaver

I have a php site I built in dreamweaver. I've been struggling with this newbie question - I have a form that submits into a MYSQL database. Most of the text fields on the form are required (I have validation rules on them). But some of the form text fields don't need to be required, so there is no validation in them. But when the form is submitted, I get the error message:

Error:
SQL error: Column 'my_field' cannot be null.

I went into the insert record wizard and set a default value for the fields that are optional (that aren't required), but I still get the error message. Should I go into the database and chnage the value from NOT NULL to NULL? Should I take the default value out or leave it in? Thanks for any suggestions. Start Free Trial
