ALL form fields empty if validity check fails on 1
25 Mar 2006 03:37:14 Kim M posted:
I have a registration page with required fields - username, password, firstname, lastname, email address.I have a serious of checks to ensure that all fields are completed - so if one field is missing (or the email address is not valid), then it returns a message which is written into the page after the Submit button is clicked (form post). If all fields are completed correctly, then the form is submitted by email and entered into the database - and the page redirects to the login screen.
The thing that is annoying me, however, is if a user enteres all the fields (name, username, email address) but maybe to choose a password - when they hit the Submit the page refreshes with the text "Please enter a password" - and all the form fields are cleared/emptied - and they have to not only enter the password, but also have to enter all the other information again.
Is there a way that I can get the information that they have entered into the form fields to stay on the page?
Cheers,
Kim

this is my way to validates user's input.
