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!

Get Button Name in Cgi

What I am trying to do is...

I have a html page of url's to pictures each line is something like

date - filesize - upload user- url to image - REMOVE (button)

the remove button name is the same as the file, i.e name="home/html/images/butterfly.jpg"

when I click the remove button it loads my cgi file, upload-cleaner.cgi.

This cgi needs to show the file name from the clicked remove button and then unlink (delete) the file on comfirmation button.

Problem is, I know how to get the value from text boxes but not the name from a button, hence in this case the name is the "value" i need to build the unlink string.

Can I get the name of the button or will I have to have a hidden textbox for every entry in the list.

Hi there,

In what inviroment are you using this feature? Is it possible for you to use javascript?
If that is an option you could retrieve the value of the button, and pass it as a parameter to the
CGI Script....

If you have this in your html:
    <input type="submit" name="home/html/images/butterfly.jpg" value="delete" />

You should be able to find out which file to delete with:
    foreach ($cgi->param) {      #Get all parameters
        next unless m!home/html/images!;    #Skip unless this is the delete button
        next unless $cgi->param($_) eq "delete";    #Skip unless this is the delete button
        unlink($_) or die "Could not remove file: $!\n";    #Delete file, or display error
    }
