<SELECT> lists on FORM validaerification

[Anon]

I am working on a form page which verifies user input. If the user did not fill out a few fields they are returned to the form to complete it correctly.

The problem comes when trying to make sure I do not lose their information when the page is returned. I have successfully figured this out for the <TEXTAREA> tags etc... however, the problem is what to do with the drop down <SELECT> lists.

I know I can write a long SWITCH statement or IF statement which will display the correct result in the returned page for each <SELECT> option, but this seems very inefficient.

How might one include a drop down <SELECT> list in such a page where the select field will reflect what the user selected the first time around?

Any suggestions would be appreciated. I guess at this point I would like to hear how others have tackled this problem.

Thanks in Advance.

The best way to do a form validation is not to even leave the page at all. You do this by using javascript. Here is the code:

<script language="JavaScript">
<!--
function formCheck(form)
{
if (form.firstname.value == "")
{
alert("Please include your first name.")
return false;
}
if (form.lastname.value == "")
{
alert("Please include your last name.")
return false;
}

 if (form.city.value == "")
 {
   alert("Please include the city you live in.");
  return false;
 }
  if (form.state.value == "")
 {
   alert("Please include the state you live in.");
  return false;
 }
  if (form.email.value == "")
 {
   alert("Please an email address.");
  return false;
 }

}
//-->
</script>

firstname, lastname, etc....are all names in the field. You can add more if statements if needed. Then, for the submit button, use this code:

<input type="submit" value="submit" onSubmit="return formCheck(form)">

If you have a select named "select" then the way i do it is to check in each <option>

<option value=1 <? if($select==1) { echo " selected "; ?>>Option 1</option>

It's a brute force method, yes, but the only way I've seen to do it in PHP. You do something similar with checkboxes and radio buttons...
