Default text in Order Comments Text Field?

[Steven300]

How can I get the order comments text box at checkout to have some text in it by default (but still be editable)?

[DrByte]

Why? If your customer doesn't change the default text, that default text will show up on your orders ... the same for everyone ... is that what you want?


To set it ...
/includes/modules/pages/checkout_shipping/header_php.php

Find this:

  if (isset($_SESSION['comments'])) {
    $comments = $_SESSION['comments'];
  }

add this on a new line below it:

  if (!isset($comments) && defined('TEXT_DEFAULT_ORDER_COMMENTS')) $comments = TEXT_DEFAULT_ORDER_COMMENTS;

and then edit your checkout_shipping.php language file and add a new define for TEXT_DEFAULT_ORDER_COMMENTS, containing whatever default text you want to show.

Thanks for your reply DrByte. The reason I want this is because I'm planning to offer an optional free product with every order. This product will be a PDF. I'm going to set this product up as document-general so it can't be added to cart and state on its product page that if you would like this, then to request it in the order comments field at checkout. So I thought I would put some default text in there and they can always remove it if they don't want the PDF. Then after their order is done, I'll email them the PDF if they requested it. Hope that makes sense.
Basically I just want to offer customers a free downloadable product with their orders but I want them to have to go through checkout in order to get it. I'm hoping it will prove to be an incentive to buy something. If you can think of a better method to do this, PLEASE let me know. Thanks.

Go ahead and see how well it works.

Thanks doc, the code works great (providing a couple of braces are added):

if (!isset($comments) && defined('TEXT_DEFAULT_ORDER_COMMENTS')) {
$comments = TEXT_DEFAULT_ORDER_COMMENTS;
}

Ok, somehow I managed to break the checkout cart when I tried this. Now when I select "Go to Checkout" from the shopping cart I end up with a blank page.

Anyone got any ideas? www.lensrent.ca

I duplicated the files before I made the code changes -- tried the code and it didn't work so I deleted altered files and renamed the duplicates back to the originals.

Just to be clear, I made the following code changes:

includes/modules/pages/checkout_shipping/header_php.php

Removed (actually I commented it out with //):

  if (isset($_SESSION['comments'])) {
    $comments = $_SESSION['comments'];
  }

Added:

if (!isset($comments) && defined('TEXT_DEFAULT_ORDER_COMMENTS')) {
$comments = TEXT_DEFAULT_ORDER_COMMENTS;
}

and

includes/languages/english/MY_TEMPLATE/checkout_shipping.php

Added:

define('TEXT_DEFAULT_ORDER_COMMENTS', 'Please enter your requested rental dates here');

Seemed simple enough.
