Multiple Radio Button Handling

[adamcoppard]

Hi folks,

New day, new problem. I've been pondering with this problem for ages.
Assume that I have a table, with four columns and x rows, with x being the number of comments you have waiting in a moderation queue. In column 1, you have the comment, column 2 an approve button, column 3 a reject, and column 4 a 'Flag as Spam' button.
Now, that could either be done as a series of checkboxes, or, a more UI friendly way, as a Radio Button handling. But, Radio Buttons are bound together by the name field, which PHP also uses for it's processing!
So, how can I get all three radio buttons mutually exclusive, and let PHP handle the lot? It's been suggest the radio button name be like so: commentid, but, how can PHP handle these, not knowing what they are going to be?

Look at the $_POST array. You don't need to know what's in an array to loop through it.

<form action="moderate.php" method="post">
<input type="radio" name="moderate_1" value="approve"> Approve 
<input type="radio" name="moderate_1" value="reject"> Reject
<input type="radio" name="moderate_1" value="spam"> Mark as Spam
Comment 1

<input type="radio" name="moderate_2" value="approve"> Approve 
<input type="radio" name="moderate_2" value="reject"> Reject
<input type="radio" name="moderate_2" value="spam"> Mark as Spam
Comment 2

...

foreach ($_POST as $key => $value) {
  if (strpos($key, "moderate_") !== false) {
    $id = str_replace("moderate_", "", $key);
    if ($value == "approve") {
      callMyApproveCode($id);
    } else if ($value = "reject") {
      callMyRejectCode($id);
    } ...
  }
}
