<?php
hook_uc_message()
?>There are many instances where Ubercart modules have configurable blocks of text. These usually come with default messages, like e-mail templates for new orders. Because of the way default values are normally set, you're then stuck having to copy and paste a large chunk of text in at least two different places in the module (when you're wanting to use the variable or to display the settings form with the default value). To cut down code clutter, this hook was introduced. It lets you put your messages in one place and use the function uc_get_message() to retrieve the default value at any time (and from any module).
The function is very simple, expecting no arguments and returning a basic associative array with keys being message IDs and their values being the default message. When you call uc_get_message(), use the message ID you set here to refer to the message you want.
Note: When using t(), you must not pass it a concatenated string! So our example has no line breaks in the message even though it is much wider than 80 characters. Using concatenation breaks translation.
An array of messages.
<?php
function uc_cart_uc_message() {
$messages['configurable_message_example'] = t('This block of text represents a configurable message such as a set of instructions or an e-mail template. Using hook_uc_message to handle the default values for these is so easy even your grandma can do it!');
return $messages;
}
