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!

Form to upload image to MySQL Database using PHP (Dreamweaver)

Asked by adammorland in PHP and Databases, Macromedia Dreamweaver, MySQL Server

Tags:

I have a very simple backend to a news section of a website. It is written in PHP in Dreamweaver using a MySQL database. It allows the user to add, amend and remove news items. The current function of the add form is adding a title (news_title), the main text (news_text) and a timestamp and ID (news_ID).

I need to add the ability to upload an image (MediumBLOB?) to the database in the same form. I have the file button in the form, but I'm stuck on the PHP end of things...

I tried adding the 'news_image' to the insert record server behaviour in dreamweaver (submit as: text) but it doesn't work. I'm sure this isn't the right way to do this but i'm new to this.....

I've attached the current PHP code before i've tried to add the image upload function.
