Hello holmanski, Sadly, this project has been aborted; the steps necessary were just too much to complete in time. What I have found, though, is that you actually need to develop the embedded operating system to get this to work. There are no pre-built browsers that I could find for this OS...

Good Day, I've been tasked with getting a web browser running on a Motorola/Symbol MT2090 barcode scanner, but it is proving challenging. Can anyone provide any advice, or literature relevant to this task? I have been following the instructions in the product documentation for the scanner, but...

Hi ingresman, Yes, I did as I said I would; I've rewrote the cart to rely on the database rather than session files, I've removed any immediate reads after a write operation (this sounds somewhat arbitrary, but the next read happens in a completely different script/page), and I've serialized...

Good Day, My problem persists, but I have suggested, and been given approval to re-architect the application. This time around, I will be ultra cautious of race conditions, and in ensuring that asynchronous requests are serialized. Thanks to all for their input. Regards, David Layzell, A+...

Hi jpadie, Thank you for the generous offer, but I would not ask that of you, or deny myself the opportunity to get my hands dirty, and perhaps habitualize some better coding techniques along the way. Also, (especially) after reading some of your posts to other users, I absolutely trust your...

Good question - I'm assuming so, the server has a huge amount of disc space, but I will confirm that there are no quotas or restrictions (as well as enough free space) with the admin when he returns to the office. David Layzell, A+, Project+ Computer Network Engineering Grad 5 years SysAdmin...

Hello, and thanks again for your input, everyone. Am I mistaken, or are the last two posts offering ~close~ to the same suggestion? (Not a problem; it is actually reassuring, if that's the case) Simply put, a mechanism to uniquely identify each request/response, ensuring they are completed in...

Hi ingresman, Yes, I am aware of the star system - vacunita has earned a handful or two from me since I joined tek-tips. :) The annoyance with this issue is it's infrequency. I am unable to duplicate the symptoms consistently to confirm it's resolution. I'm intending to see a period of time...

Thank you vacunita and jpadie. I was thinking the same thing after finding the above chipmunk ninja link on google. I am going to be taking whatever steps I can to "ease the load" on the session handler, and I will report back if this corrects our problem. (Maybe - it is so intermittent, I am...

More info: This script is called on pretty much every change of the store form controls. Here is the shopping cart class, as well, if it helps: <?php class Shopping_Cart { private $cart; function __construct($cart="") {$this->cart = $cart;} function getCart() {return $this->cart;}...

My apologies, too unaccustomed to this forum. Here is the script I attached: <?php include("config.php"); include("cart.class.php"); session_start(); // Make a working copy of the shopping cart from session data // $items = $_SESSION["cart"]; $tix = array('1', '2', '3', '4'); $rooms =...

Good Day, I have written a small, PHP shopping cart application, with the customer's selections being stored in a session variable. Unfortunately, the session data is intermittently lost while proceeding through the checkout flow. I need to resolve this. There are 3 pages, and a couple of...

That's it! It's working perfectly now! Phil, I owe you a beer! Starring every post. Thank you. David Layzell, A+, Project+ Computer Network Engineering Grad 5 years SysAdmin, 11 years hobbyist Dev http://www.davidlayzell.com

Alright, I've been pulled away from this project for awhile, but I've been playing with this again, and I've found an issue (maybe two) that I can't seem to get my head around. Here's the latest code: if(isset($_GET['dir']) && is_dir($_GET['dir'])){$path=$_GET['dir'];} else{$path="./";} if...

Ohhhhh, yes!! Phil, you are my hero; always pointing out the simple things I've missed. I THOUGHT there would be a php function for this, but my research failed, obviously. Let me try this out! This might save me my from my mess of SQL, and javascript form handling bullswaddle. David Layzell...
