Form Validation - Multiple input field validation

[E-AN]

I need to validate two forms containing multiple input fields but want just one error message if any of the fields are left blank, the page is required to submit the users details (registration form). Also if any of these fields are left blank i don't want to be able to go to the next page on clicking the submit button

[Graphix]

You should try the following:

- Add an id for every input and form
- Write a global function that checks the value (for example check_email(inputid) or check_name(inputid) )
- Use the event onsubmit() in each form tag. In that event you should call a fuction: onsubmit="return checkform(this.id)"

- The function checkform(formid) should return atrue if all fields have been entered correctly or false if not
