form check: combine php and javascript

[Anon]

ok I want to make a form check to see if a person filled in all the information.
the problem is now that the "submit" button is not a "input type="submit" button, but it is a javascript like this

<script language="javascript">

          function abschicken()  {

            document.forms[0].submit()

          }

          </script>

          <a href="javascript:abschicken()" class="link1"><b>&gt; senden</b>

now I want my php script is that it checks if the user has pushed the button "submit":
like this
if ($submit) { etc. etc. etc.

now how can I all this javascript?

Your options are:

1. Changing your form to use JavaScript for the validation;
2. Submit the form to the server with, using a submit button (not a 'type=button' button) and use PHP to validate the form fields on the server.
3. Use JavaScript to perform the form validation on the client, and then re-validate the form once its submitted, using PHP, on the server-side of the connection. Be careful that you're validation criteria used on the server is absolutely the same as any JavaScript validation used on the client...

JavaScript executes on the client browser, PHP executes on the server. A server-side validation mechanism is, IMHO, preferred, since most browsers will allow users to disable Javascript, but you can't disable the PHP interpreter on the server from your browser.
