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!

Using an array where the values are variable names

Asked by jonnyz0109 in PHP Scripting Language, Web Languages/Standards, WebApplications

Tags: , ,

I am having a hard time wrapping my head around a challenge I've run into.  I am building a form validation function, and I would like it to be dynamic based on a settings file I'm including.  The settings file has an array of required variables, and I would like to iterate through this array and access the data inside the variables that are specified.

Of course, the simple solution is to check field by field, but I want the validation code to be reusable, and also for the list of required fields to be easily modified in the settings file.  If you have other suggestions as to how to go about this, let me know.

Please see code snippet for more info.

Thanks in advance,

global $RequiredFields;
$RequiredFields = array("FirstName","LastName","Email","EmailConfirmation","Comments");
 
if (in_array("", $RequiredFields) == true) { // Check to see if any fields are empty
	$Validation = false; // throws generic error on the top of the page
//	iterate through the fields specified and determine which are blank
//	additionally, print out the data in each variable for debug purposes
