Synergic

btw if i change getBook to getBookX i get invalid method, so i know i can connect to the web service.

anyone? been stuck on it for days....

I have a web service which i want to consume via PHP. Whenever i attempt to communicate with it it comes up with: "Server was unable to process request. --> Object reference not set to an instance of an object." Googled it and got the following: http://php.net/soap_soapclient_soapcall Apparently this code should work to fix the above problem: <?php class Test { public $account; public $password; } $parameters = new Test; $parameters -> account = $username; $parameters -> password = $password; try { $client = new SoapClient ("https://www.somewebsite.com/Serv­ ice.asmx?wsdl", array('classmap' => array('CheckUser' => 'Test'))); $client -> CheckUser ($parameters); echo "Valid Credentials!"; } catch (Exception $e) { echo "Error!<br />"; echo $e -> getMessage (); } ?> I modified it and my version as follows: <? class Book { public $author = "1"; public $title = "2"; public $publisher= "3"; public $loc= "4"; } $bookC = new Book; $sc = new SoapClient("URLTOWEBSERVICE?wsdl",­ array('classmap' => array('bookC ' => "Book"))); try { print_r($sc->getBook($bookC)); } catch (Exception $e) { echo $e->getMessage(); } WSDL as follows: - <s:complexType name="Book"> - <s:sequence> <s:element minOccurs="0" maxOccurs="1" name="author" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="title" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="publisher" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="loc" type="s:string" /> </s:sequence> </s:complexType> Been stuck on it for a while, any ideas? I've also tried using nuSoap with the same result. :|

$months[01] = "Jan"; $months[02] = "Feb"; $months[03] = "Mar"; $i = 02; // also tried "02" echo $months[$i]; The above code has me stumped (echos nothing). Coming from a Java background I've had no such troubles substituting array indices with variables. When i change the $i (in between the brackets) with 02 it appears to work. Any ideas?

thanks alpine, i figured it out from your code.

I have a drop down menu, i also have a value so when the form is loaded i want to select the drop down menu item based on the string. I tried all combinations and i just can't get it to auto select the drop down menu item based on the string (they're EXACTLY the same) any ideas?

heh whoops yes it works now: [code] $a = 10/100; $b = 1000; $b = $a*$b; echo $b; [/code]

i don't know why the following isn't working. I'm trying to calculate 10% of a value? [code] $a = 10/100; $b = 0; $b = $a*$b; echo $b; [/code] it just gives me 0 :|

ok solution was to: [code] $sql = "INSERT INTO userinfo VALUES ('','".$user->getUserName()."')"; [/code] ???

and if i pass a $user object with a username, password i can print it within the function, it works. However if i use it in the insert statement i get undefined variable: $sql = "INSERT INTO birthdays (name, birthday) VALUES ('$user->getUserName()', '$birthday')";

actually i still want to use OO concepts. i still can't figure out why the original code doesn't work. If i remove the variables and insert values instead it works no problems. The funny thing is if i declare the variable locally and use it, it works.

i haven't figured why i'm getting unidentified variable with the following insert statements. i mean using values work fine but as soon as i stick a variable inside the insert clause i get unidentified variable: [code] <?php include_once 'DatabaseClass.php'; class BookStoreClass extends DatabaseClass { var $name = 'hello'; var $birthday = 'hello'; function registerUser($user) { parent::connect(); mysql_query ("INSERT INTO birthdays (name, birthday) VALUES ('$name','$birthday')"); parent::close(); } } ?> [/code] Notice: Undefined variable: name in Notice: Undefined variable: birthday in

As part of making my code more elegant and following an mvc pattern i want to store a query result inside a variable where i can invoke it else where besides the presentation layer. I've tried: [code] $result = mysql_fetch_array($quer); while($result) { } ends up being an endless loop. Do i need to continue to update the variable as i scroll through the rows? [/code]

nerver mind, my bad :) thanks for the help.

[quote author=ToonMariner link=topic=104209.msg415452#msg415452 date=1155565618] Don't! Just have a table of artist and a field for their publisher [/quote] for simplicity i have kept things in one table. i will fix the structure once i've figured this problem.

Ok i've got a CD catalog in a database. I have a cd table in the cd table i have a column for the artist, song and publisher. What i want to do is list each artist under their publisher so something like Sony/BMG   Artist 1   Artist 2 Universal   Artist 1   Artist 2 I'm just having trouble approaching the problem of printing it out. How do i populate each artist under their respective publisher?

ok fixed, the problem was 'cart' was an object i got confused with 'it' being an array. I accessed the array inside [i] cart [/i] which is [i] items [/i] and recieve a 0 :)

[code] <? if (isset($_SESSION['cart'])) { echo 'Array is set.'; } ?> <?echo '<pre>';   print_r( $_SESSION ); echo '</pre>';?> [/code] result: [code] Array is set Array (     [cart] => ShoppingCartClass Object         (             [items] => Array                 (                 )             [totalPrice] =>         ) ) [/code] what gives?  :-\

yeah but if i add something to the array it gives me 1. It's hard to tell if its really empty or not...

why do both these functions: sizeof -- Alias of count() count -- Count elements in an array, or properties in an object give an array size of 1 even though there's nothing inside it? I then add something to it and it gives me 1 still then 2. what is in index 0? i need to do some manipulation and have to check if an array is empty.

I'm creating a simple, non-presistent shopping cart. Currently it allows a product ID and a qty. What i want is without re-writing the code below a simple way of adding a third variable such as a description. Any ideas? Since the array only accepts one associated field inside it i can't seem to figure how to add a third attribute. [code] <?php class ShoppingCart {     var $items;       function add_items($product_id, $qty, $desc)     {       $this->items[$product_id]=$qty;               }     function update_items($product_id, $qty)     {       if(array_key_exists($product_id, $this->items))       {           if($this->items[$product_id]>$qty)           {             $this->items[$product_id]-=($this->items[$product_id]-$qty);           }           if($this->items[product_id]<$qty)           {             $this->items[$product_id]+=abs($this->items[$product_id]-$qty);           }           if($qty==0)           {             unset($this->items[product_id]);           }       }     }       function remove_item($product_id)     {       if(array_key_exists($product_id, $this->items))       {           unset($this->items[$product_id]);       }     }     function show_cart()     {       return $this->items;     } } $cart = new ShoppingCart; $cart->add_items("test", "2", "3"); //$cart->remove_item("Apples"); $cart_items=$cart->show_cart(); foreach($cart_items as $key=>$value) {     echo "$key $value<br>"; } ?>[/code]
