Reset in form

I have a form that posts to itself. Data validation occurs when the user clicks the Submit button. If validation succeeds then an email is generated and sent, otherwise the form is redisplayed. I repopulate the form fields so the user doesn't need to re-enter the same data, like so: <input type="text" name="FromAddr" size="25" <?php print "value=\"$FromAddr\"><font color=\"#FF0000\"> $FromAddrErr"; ?> </font></font></p> Everything works fine, except for Reset. If the user enters data into the fields and clicks on Reset before clicking on Submit, then all fields are cleared. However, once Submit has been pressed the Reset button doesn't clear the data in fields that was entered before the last submit. This is because the variable(s) now contain the data, and the Reset button can't clear the variable. However, I'm having trouble detecting in PHP that the Reset button has been pressed. I need to detect this so that I can reset all the variables to empty. Is this possible and if so how? How does the "Reset" operation work? Does the browser simply return all the fields to the values that were set when the form loaded? If this is the case then I won't be able to use the "Reset" button. I can't use Javascript either. For example, I can use Javascript to change the value of the text field (to "") but then it's immediately changed back by the form refresh. I can prevent the form refresh by using return false; However, if the user refreshes the page then the original value is restored because I still haven't actually reset the variable value.
