Adding Field to Checkout

[eddyboy]

That time to bug you for help again

Ive tried and got no where with trying to make a feild required

I am also struggling with a seperate javascript fix

So once again, any help or pointers on making a feild required would be very much appreciated.


Im sure a donation will be made, for the help in the forums and for the zencart system when my site is up and running
I have made a fair few mods as well that I'd like to share with others, once the dust has settled.

Ok, from the top!

The way you add new fields has been shown earlier in this thread.

To make them required, edit the header_php.php file you are currently working with - there should only be one. It's the one where you have $_SESSION['xxxx'] = $xxxx

If there is a variable set somewhere in this page called $error, which is either true or false, you need to follow the same protocol.

If not, then you can use this:

  if (!zen_not_null($_POST['my_variable_name'])) {  //perform ALL checks on relevancy here
    $messageStack->add_session($_GET['main_page'], TEXT_ERROR_VARIABLE_MISSING, 'error');
    zen_redirect(zen_href_link($_GET['main_page']));
  }

It's not the prettiest way of doing it, and if the customer has entered an entire page of data, and then comes across this type of error they will hate you, as none of their data will be re-populated, but as I don't know where you are adding the details, or what other modules you have installed, it is the only fail-safe way of doing it I can think of.

  if (!zen_not_null($_POST['my_variable_name'])) {  //perform ALL checks on relevancy here

    zen_redirect(zen_href_link($_GET['main_page']));
  }

Thanks for the speedy reply.

I have been editing the checkout_shipping/header_php.php page as i have put the new form on the index.php?main_page=checkout_shipping page. And I have gone through the code a few times but cant find any examples to copy.


Anyway, I put in the new code so it reads like this

if (zen_not_null($_POST['address'])) {
$_SESSION['address'] = zen_db_prepare_input($_POST['address']);
}
$address = $_SESSION['address'];

if (!zen_not_null($_POST['address'])) {  //perform ALL checks on relevancy here
    $messageStack->add_session($_GET['main_page'], TEXT_ERROR_VARIABLE_MISSING, 'error');
    zen_redirect(zen_href_link($_GET['main_page']));
  } 

but i get a redirect loop error-

Redirect Loop
Redirection limit for this URL exceeded. Unable to load the requested page

.

Im asuming this is because when the page first loads the variables have no value

Again, thanks for your patiance and help.. I am coming to the end of what hasbeen a very long project, and my brain is starting to fail me All and any help is much appreciated

I think i have a work around.

If I change a form feild to include some defult text

<?php echo zen_draw_textarea_field('address', '45', '3','required feild') ?>

and tweak your last bit of code to

if (($_POST['address'] =="required feild")) {  //perform ALL checks on relevancy here
    $messageStack->add_session($_GET['main_page'], TEXT_ERROR_VARIABLE_MISSING, 'error');
    zen_redirect(zen_href_link($_GET['main_page']));
  } 

It means unless they change the text for something they enter it will throw an error.

I think my brain has something left inside it after all

Firstly, move that code so it comes BEFORE the if (zen_not_null($_POST['address'])) { line.

And then change it so it reads:

if (isset($_POST['address']) && !zen_not_null($_POST['address'])) {  //perform ALL checks on relevancy here
    $messageStack->add_session($_GET['main_page'], TEXT_ERROR_VARIABLE_MISSING, 'error');
    zen_redirect(zen_href_link($_GET['main_page']));
  }

I'm at the point of testing my site online now and I have set up paypal website payments pro and express checkout. I have made 2 successfull orders, 1 with a credit card and one through the express checkout. However I have just noticed that the details for the new feilds that I have made have not made it through to the database when using the express checkout, but the info from the new feilds is there for the order that I payed with using a credit card.

Just wondering if anyone has come across this before or can think why it would be an issue ?

Thanks in advance

Ok so when you checkout with expresscart this page is skiped and you are returned to the next page in the process. Trouble is i need those feilds to be filled out.

I guess I need to move the feilds or find out how to change the redirect url after using express checkout

Edit your PayPal Express Checkout module settings and turn off the setting that auto-selects cheapest shipping.
