Help with auto submit form

[studiopix]

I've made a little cart with PHP with a calculator, I create a SUBMIT button (to get my calculator works) - Is there a way to get rid of this button? Make the form automatic refreshing. For example if I load the page my 'quantity' is'nt updated...

this is a javascript thing and it really depends on when you want to send the form. you might want to take a look at the javascript onChange() event.

form action="<?php echo $_SERVER['file://///Frank/serveur/HTTP/Teampneumatik/canada-fr/compresseurs/PHP_SELF']?>" method="post">

              <?php

  extract($_GET);
  extract($_POST);

  // CHANGE! your email address signed up with PayPal
  $paypalemail = "[e-mail]";

that really doesn't help much. you sure you wrote this code? i meen, if you wrote this, surely you would know how to fix your problem.

why not ask the author?

[studiopix]

I just need to know how to make a 'condition', like use 'if'. I want to say if the quantity = (-1) change it to (+1). Or either say that the default value fo quantity is '1'

[thorpe]

if ($quantity < 1) {
  $quantity = 1;
}
