So I had a great post explaining how to get the value of a radio button if they are dynamically created (such as through a database query) and unforunatly it was lost. Just today I noticed that it was somehow changed to another post about breadcrumbs. I’d like to think I will come back and create another quality post on how to get values of dynamically created, database driven radio buttons.. but until then, here is the short version:

Basically what you are going to want to do it assign a loop counter variable, and add it to the end of each radio button name:

$loopCount = 0;
while($result = mysql_fetch_array($query))
{
   echo "$result[name]";
   $loopCount++;
}

Now when we are error checking values, we can start at 0 and loop until the variable no longer exists.

while($_POST['radioSet' . $i])
{
  //Error check value, post to database, whatever needs to be done
}

Here you can see, regardless of how many “radioSet” inputs we have, our error checker will get them all. In this example I only gave one radioButton for each input name. Of course for each loop, you can have multiple numbers of inputs. Also, you can give each element an ID using a similar naming tactic, which would allow you to control them all with javascript using document.getElementById.
