Form Validation Bug

[hanlonj]

Hi,

I am validating a form on a page using the [code]$_SERVER[PHP_SELF}[/code]superglobal.

I check for empty fields and display an error beside the field that is empty so the user will know what to correct (as per usual on a website).My problem is that when the page loads initially, the form is as you would expect empty. so the errors appear upon first loading of the page.

I realise this is easy to fix but the solution is escaping me at the moment.

Can anyone help?

that means, you are probably running your validation without ever seeing whether or not the form has been submitted. let's say you have your submit button simply named "submit", you'll need to wrap your entire validation and processing within something like this:
[code]
<?php
if (isset($_POST['submit'])) {
  // process your form here.
}
?>
[/code]

Excellent, worked no problem.

Thank  you very much.
