Adding Field to Checkout

[eddyboy]

Ive been wracking my brain for a few hours now on how to make a radio button group

I found

function zen_draw_radio_field($name, $value = '', $checked = false, $parameters = '') {
    return zen_draw_selection_field($name, 'radio', $value, $checked, $parameters);
  } 

in includes/functions/html_output.php and I can get it to show a button on the page if i declair $name, $value, but i have no idea what $parameters should be.

Obviously I have more than one set of options and values so im at a loss on how to get my options and values output onto the page.

Any help or pointers to some example code is much apreciated

Thanks in advance

Parameters is a catch-all for anything else you need e.g. 'class="myRadioButton"'. You don't have to put anything in there if you don't need anything.

You would use this function once of each option/value combination, grouping the options by giving them the same name, with each value for that option having its own unique value.

You'll probably want to sprinkle lightly with LABEL tags too.

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
    $messageStack->add_session($_GET['main_page'], TEXT_ERROR_VARIABLE_MISSING, 'error');
    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']));
  }

Anybody have any idea how I might add a checkbox that will enable users to split the shipment of their product should they desire to do so? I'd have to be able to see it in the orders area of the admin as well. I'm not particularly PHP savvy, in fact, I know just enough to get myself into trouble to be perfectly honest...all I've been able to get done so far is adding a split_shipment field in the orders database...
