Ok so I have a donate page on a site I built.

Right now I just left the price blank so they can enter an amount in.

Is there a way to have a drop down with various amounts AND the empty text box as an other option?

You can. Just do a check after submit - if textbox empty use the amount from dropdown else use the amount from textbox. Also have to do check textbox allows numbers only. You have to do js client side check but also server side check in case js is turned off in customers browser

ok I can do the JS part, but how do I do the server side part?

Noob at PHP but perhaps something like this?

$var = intval($_POST['formName']);

[ARW VISIONS]

yeah, Im a design guy, so writing PHP to check that might be over my head. I'll check it out.

Stupid forum submitted my post before I wanted.

What I posted before was simply making sure it was posted as an integar.
For checking which was submitted you could do maybe something like this:

$var = intval($_POST['formName']);
$var2 = intval($_POST['dropdownName']);

if($var > 0 && $var2 > 0) {
Both have stuff in them.  You decide which to use
}

if($var > 0) {
Value was found and is greater than 0  in the form.  Do php stuff
};

if($var2 > 0) {
Value was found and is greater than 0 in the dropdown.  Do php stuff
};

Again, I'm a noob at php and may be insecure or used too much logic/faulty logic.

Yes you need to do that in the php file responsible for processing the form. Something like
var1 -dropdown
var2 - text field

P.S. same happened to me - forum submitted before I finished

PHP Code:

if (!empty($var2)) {
 # use text field value
 if (!is_numeric($var2))
  $error = true;
  # if field value is not a number throw an error, process it and redirect back to the form for re-submision
 else
  # if field value is a number
  $var2 = intval($var2);
 # do more php stuff
} else {
 # if text field is empty use dropdown value
 $var1 = intval($var1);
 # do more php stuff
}
