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...

Good Day Fellow Tekkies, I have a web project that I'm trying to complete on the double. I apologize if this is the wrong forum, but I'm using a multitude of languages, and thought this would get the most visibility. My functional requirement is navigation of a directory of files (ie, lists of...

Okay, I've discovered my issue. I was using the p_div parameter in the context of my working code and not your example, yes, but what I failed to do was reload my .js file. The HTML was refreshed with the this keyword (instead of passing this.id), but the .js was still in cache expecting this.id...

This example does not work either. (This was one of the first combinations I tried now that I think about it) Thank you for the explanation of datatypes and parameter passing though. Always good to have a refresher of the basics once in awhile. The link should be helpful. I'm leaving my code as...

Ahh, of course. Thanks for that. Then, is this an altogether unrelated keyword in javascript? It does appear to be valid syntatically (although obviously being used wrong) inside my .js file. David Layzell, A+, Project+ Computer Network Engineering Grad 5 years SysAdmin, 11 years hobbyist Dev...

Thank you for the reply, Phil, I had been using the parameter to load a variable with GetElementByID, and I did think that it was redundant. However, I'm now trying to use this directly in my function, and I'm not getting anywhere. Here's some working (albeit inefficient) code: function...
