Hey great script! This will save so much time. Now I just have to go back and get all my old scripts to use it. I did run into one problem and I wanted to see if you may have a solution.... If you have input fields like the following: <input type="text" name="phone1[1]" id="phone1[1]">- <input type="text" name="phone2[1]" id="phone2[1]">- <input type="text" name="phone3[1]" id="phone3[1]"> It will not fill in the values. I guess it doesnt recognize how to fill in an array of values with <? echo $_POST['phone1'][1] ?>, etc.... Any ideas how I could modify the script or if its possible??

  I was wondering when somebody would notice that it doesn't handle PHP's built-in support for arrays of form fields.
  
  On a scale of 1-10, that will be about a '6' to fix; it will involve changes to the fillInInputTag() and fillInTextArea() (and maybe fillInSelect) functions, where they fetch the "name" attribute (gotta be smarter about name="foo[]", and keep track of which array index is being parsed, and find the corresponding value in $request).

  Well, I don't use it everywhere. I only use it for text fields. So I made the following addition to fillInInputTag()(Note: i'm not very experienced with the best solutions to these problems, nor do I use regular expressions often):
  
  $num_of_matches = preg_match("/([\w]+)(\W([\d]+)\W)/", $name, $name_match);
  
  $name_arr = $name_match[1];
  $name_index =$name_match[3];
  
  if($num_of_matches == 0) {
  if (!array_key_exists($name, $this->request))
  return $tag;
  return fillInFormHelper::replaceAttributeVal($tag, 'value', $this->request[$name]);
  } else {
  if (!array_key_exists($name_arr, $this->request))
  return $tag;
  
  return fillInFormHelper::replaceAttributeVal($tag, 'value', $this->request[$name_arr][$name_index]);
  }
  
  In my input names, I add a index number instead of just using name[]. I think this gives me better control, plus I can use the above method to fill in the text fields. Now, I just need to figure out how to do the same thing for the validateForm function....
  
  Your scripts have made me life creating version 2 of our website 100X easier. Expansion will be much easier as new fields are added to the forms and database backend! Thanks and feel free to comment on what I did above...
