I am ignoring AJAX and JS for now

steaknchips — Sun, 29 Aug 2010 20:27:45 GMT

I have a problem and am unable solve it:

5 products, 4 prices based on size for ea product.

if my url looks like this www.domain.com/products/3

the product id is '3' but there are 4 prices associated with this one product.

by clicking on the image sm, me, la and xl the price changes 'oncreen', however

I cannot get the cart functions to reflect this change re size/price in the 'on screen cart text display area' or in the checkout screen; it keeps pulling the same price

here are the the functions: this is the third 4th day of messing with this....

ADD TO CART FUNCTION

PHP Code:


		
			
function add_to_cart($id)
  {
    if (isset($_SESSION['cart'][$id]))
    {
      $_SESSION['cart'][$id]++;
            return true;
    }
        else
        {
            $_SESSION['cart'][$id] = 1;
      return true;
        }
        
        return false;    
  }

TOTAL PRICE FUNCTION

PHP Code:


		
			
  function total_price($cart)
  {
        
     $price = 0;
         
         $connection = db_connect();
         if(is_array($cart))
       {
             foreach($cart as $id => $qty)
             {
                 $query = mressf("SELECT price FROM photos_products WHERE photos_products.id = '%s'", $id);
                 $result = mysql_query($query);
                 if($result)
                 {
                     $item_price = mysql_result($result, 0, 'price');
                     $price += $item_price * $qty+ $prc;
                 }
             }
         }
          return $price;
  }

PHP Code:


		
			
  function total_items($cart)
  {
     $num_items = 0;
         
         if(is_array($cart))
       {
             foreach($cart as $id => $qty)
             {
                 $num_items += $qty;
             }
         }
         
         return $num_items;
  }

PHP Code:


		
			
function update_cart()
    {
      foreach($_SESSION['cart'] as $id => $qty)
        {
            if($_POST[$id] == '0')
            {
                unset($_SESSION['cart'][$id]);
            }
            else
            {
                $_SESSION['cart'][$id] = $_POST[$id];
            }
        }
    }

any advice would be appreciated

thank you, thank you, thank you.....thank you

the DB looks like this

price - 12.99
price_medium = 22.99
price_large = 27.99
price_xl = 39.99

PHP not returning the correct value

Kev0121 — Sat, 28 Aug 2010 18:09:29 GMT

Right basically what im trying to do is echo out the current value of the players health when its been attacked by the mob, so it should echo out 25 but its echo'ing out 50

PHP Code:


		
			


class Monsters

{

    public $name;

    public $type;

    public $id;

    public $HP;

    public $MP;

    public $dmg;

    public $defence;

    public $playerHealth = 50;



    public function attack($name, $dmg)

    {

        echo "$name attacks you with a damage of $dmg 
";

        $this->playerHealth - $dmg;

        echo "Your players new health is - $this->playerHealth";

        return $this->playerHealth;

    }

}



$mob = new Monsters();

$mob->attack("Balrag", 25);



?>

Mysqli Sum Question

votter — Fri, 27 Aug 2010 11:19:20 GMT

PHP Code:


		
			
$Test = ("SELECT Test, SUM(IF(Test = 'Til', 1,0)) AS `T`, SUM(IF(Test = 'Sil', 1,0)) AS `S` FROM `Show` GROUP BY `Test`");  



$get = mysqli_query($mysqli, $Test)or die("Error: ".mysqli_error($mysqli));  



$gg = mysqli_fetch_array($get);  



echo $gg['T'];  

echo $gg['S'];

When I try something like this, I can get the correct result for the first sum, but after that, it reverts to 0. I was wondering how I could get this to work for both. Thanks again.

Color Stream - iPhone App

Littlej — Thu, 26 Aug 2010 11:39:35 GMT

Just read on Smashing Magazine that the iPhone App "Color Stream" was being released for free: http://www.smashingmagazine.com/2010...web-designers/

I downloaded it and basically it's like kuler for the iPhone. It has a very nice interface and obviously makes all your palettes very easily accessible. One cool feature it's got over kuler though is that you can take a photo or use an existing photo and it will generate a palette from that - I tried it out by taking a photo of my couch (it's a dark mocha sort of colour with lighter cream cushions) and the palette it made was really good.

Check it out if you have an iPhone :)

routing system errors

kshuck2 — Wed, 25 Aug 2010 21:08:39 GMT

It seems like every other new thread I make is a problem to do with a routing system, but I think its great and have used them on all my recent projects...

I am getting a really weird situation where you click on a link, and it will take you to the right page but will display the error "this page has been moved or does not exist" like it does when there isnt a route found. the kicker is that it only happens every now and then and on its hard to reproduce if I try. It seems to be only on a couple pages. But I never ran into it when the site was on my local machine.

It is very annoying especially for the website owner. Does anyone have any ideas what it could be or what I should try to narrow down the cause??

any response is appreciated, thanks

Virtual drive from network share

JAY6390 — Wed, 25 Aug 2010 15:26:28 GMT

Hey boys n girls
I've got myself a nice shiny new network drive. All works great, but unfortunately I can't access it with windows 7 backup because win 7 doesn't allow network backups on home premium. I was thinking it might be possible to fake a drive on my computer like you can with an ISO and say virtual clone drive, but I've not managed to find anything

I'm sure someone will ask if I have mapped it as a network drive, and the answer is yes, but that doesn't work either :(

Any help with this would be appreciated

Jay

I got an Email!!

this came in from my ISP today...

Hi Mr,

Big news! We're switching your existing Naked Home 5 service to our new and improved Naked Home-2 plan at no extra cost.

You might have heard we're kicking off an exciting new suite of broadband plans. Improvements to your plan will more than double your existing quota, giving you a massive 260GB of extra room to move online.

Here's a closer look at the changes:

old quota

70GB peak
70GB off-peak

new quota
200GB peak
200GB off-peak

But that's not all - we've also increased shaping speeds on your new Naked Home plan to a big 256kbps. Nice!

My view on Art

de.monkeyz — Mon, 23 Aug 2010 13:57:35 GMT

I made a semi-interesting blog post a moment ago on my view on art in regards to programming. Hopefully some of you can give it a read - http://www.deathmonkeyz.com/post/usi...to-create-art/ (if it's down, it's because I chose a bad time to upgrade WP version)

Just wanted to see what other people's opinions on this stuff is
