Variable call- character limit per line

[theisurgeon]

My shipping software .php file pulls notes in from Magento.  Problem is, after a certain number of "note" characters, the invoice does not print properly on my thermal printer (not sure the character limit, so I will need to use trial-by-error.  I am assuming there should be an easy string limiter code to cut the excess characters and possibly append an ellipsis?  Please help!

 

 

 

 

writeStartTag("Notes");

 

// check for order-level gift messages

if ($order->getGiftMessageId())

{

$message = Mage::helper('giftmessage/message')->getGiftMessage($order->getGiftMessageId());

$messageString = "Gift message for ". $message['recipient']. ": ". $message['message'];

 

if (trim($message['recipient']) != '') {

writeFullElement("Note", $messageString, array("public" => "true"));

}

}

 

$orderComments = $order->getAllStatusHistory();

 

foreach ($orderComments as $comment) {

$body = $comment->getData('comment');

if ($body != '' && strpos($body, 'Order imported from') === false) {

writeFullElement("Note", "*** Buyer message: $body", array("public" => "true"));

}

}

 

writeCloseTag("Notes");

strlen

substr

 

$max_length = 50;
$ellipsis = '...';
if ( strlen($mystring) > ($max_length + strlen($ellipsis)) ) {
  $mystring = substr($mystring, 0, $max_length) . $ellipsis;
