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!

jQuery/PHP
Hello Experts,

I am having trouble with the Facebox jQuery plugin. I am displaying a contact form in a Facebox window, and I am trying to get a postback from the PHP form submission to display in the same Facebox window. I have read that you can use iframes (this sounds like cheating) and that works, but I want to know if anything can be done to catch the postback from the form so that it does not display/refresh the entire page behind the Facebox popup. I have enclosed the Facebox code for your perusal.

Thanks in advance for any and all help.

/*
 * Facebox (for jQuery)
 * version: 1.2 (05/05/2008)
 * @requires jQuery v1.2 or later
 *
 * Examples at http://famspam.com/facebox/
 *
 * Licensed under the MIT:
 *   http://www.opensource.org/licenses/mit-license.php
 *
 * Copyright 2007, 2008 Chris Wanstrath [ chris@ozmm.org ]
 *
 * Usage:
 *  
 *  jQuery(document).ready(function() {
 *    jQuery('a[rel*=facebox]').facebox() 
 *  })
 *
 *  <a href="#terms" rel="facebox">Terms</a>
 *    Loads the #terms div in the box
 *
 *  <a href="terms.html" rel="facebox">Terms</a>
 *    Loads the terms.html page in the box
 *
 *  <a href="terms.png" rel="facebox">Terms</a>
 *    Loads the terms.png image in the box
 *
 *
 *  You can also use it programmatically:
 * 
 *    jQuery.facebox('some html')
 *
 *  The above will open a facebox with "some html" as the content.
 *    
 *    jQuery.facebox(function($) { 
 *      $.get('blah.html', function(data) { $.facebox(data) })
 *    })
 *
 *  The above will show a loading screen before the passed function is called,
 *  allowing for a better ajaxy experience.
 *
 *  The facebox function can also display an ajax page or image:
 *  
 *    jQuery.facebox({ ajax: 'remote.html' })
 *    jQuery.facebox({ image: 'dude.jpg' })
 *
 *  Want to close the facebox?  Trigger the 'close.facebox' document event:
 *
 *    jQuery(document).trigger('close.facebox')
 *
 *  Facebox also has a bunch of other hooks:
 *
 *    loading.facebox
 *    beforeReveal.facebox
 *    reveal.facebox (aliased as 'afterReveal.facebox')
 *    init.facebox
 *
 *  Simply bind a function to any of these hooks:
 *
 *   $(document).bind('reveal.facebox', function() { ...stuff to do after the facebox and contents are revealed... })
 *
