Loop a form variable??

griffith

If I have this form variable:

$name = name1, name2, name3;

How do I then loop it, and get each of them out.. if you understand..???

I think I understand what you're getting at:

  while (list($key,$val) = each($HTTP_POST_VARS)) {

    echo "Key: $key => Value: $val<br>\n";
  }

This should print all the submitted values to the screen. Modify it to use the variables as you intend. If your form method is GET instead of POST, use $HTTP_GET_VARS. HTH.

Well.. don't think that was exactly what I ment.. because there is ONE form variable (<input type="text" name="name">), and in this one.. people might type : name1, name2, name3, and so on... therefor I need to split it up.. but not sure how to do that..

Ahhh..... if you know what the character(s) separating the names will be, you can use the explode function:
<br>
$names = explode(",", $name);
<br>
    while (list($key,$var) = each($names)) {
<br>
    // remove any extra whitespace
      $names[$key] = trim($var);
    }

HTH.
