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!

getting variables to CSS and JS files that are link from HTML that is generated by Front Controller

Asked by AlexanderR in PHP Scripting Language

Tags: ,

Hello.
I am on an adventure of making my own Front Controller that i can use on my projects.
What i have now is mostly functional.  Most of the ideas were taken from http://w3style.co.uk/a-lightweight-and-flexible-front-controller-for-php-5 .  Then i added my own loader class for dynamically loading classes other classes through singleton, configuration class to make configs loadable and available application wide etc.
But i've hit a wall AGAIN when i have to pass variables to CSS or JS.  Normally a controller would set up the variables and they would be passed on to the view.  However, CSS file is technically not a part of the view generator because it is not linked through controller, like a view, but through HTML which is already generated: hence when html calls for a link to css or js its maks a totally different call to the PHP application.

So how can a CSS or JS file that is linked in HTML receive variables from the controller.

Attached are some portitions that i think are relevant.  CSS and JS files are linked in the view.header_template.phpStart Free Trial

// a section from the module that does the actual business logic
class index extends ActionController {
	public function guest() {
		$this->user = "guest";
		$query = "SELECT * FROM system_group";

// section from a view that points to troubled css
<html>
<head>
	<title>title</title>
		<link rel="stylesheet" type="text/css" href="<?php echo $css_dir; ?>css_file.php" />
 
//css file has header("Content-type: text/css");  in it. This way it supposedly accepts variables and fills in the css file.
