load text in a page

[ShaolinF]

Hi Guys,

 

What I want is when a user doesnt fill in a field on a form and presses next, I want that page to say 'Error, you have not filled in this field', rather than having to load another page with the comment. How can I do this ?

Thanks. I managed to find a way but cant get it to work. Here is the thread if you want to give a hand: http://www.phpfreaks.com/forums/index.php/topic,163447.msg716558.html#new

try this instead:

 

<form action="continue.php" method="post" name="signup" onSubmit="return myformcheck()">
<p align="center">
Username: <input type="text" name="name" size="20"><br>
Password: <input type="text" name="contact" size="20"><br>
E-mail : <input type="text" name="email" size="20"><br>

<input type='submit' value='Go'>	

<script language="Javascript">
  function postregister()
  {		  
	  if ((document.signup.name.value == '') || (document.signup.contact.value == '') || (document.signup.email.value == ''))
	  {
		alert('You have to enter a valid name, contact number and email.');
	  }
	  else
	  {
		document.signup.submit();
	  }
  }
</script></form>

 

post back to let me know if it works.
