Need an associative array but with the same keys for NuSoap

Question 1

This is not how I would have expected it to work, but the below works:

$orderItemRequest = array();
$orderItemRequest['OrderItemRequest'] = array();
foreach ($item_cart as $product) {
    array_push(
        $orderItemRequest['OrderItemRequest'], array(
                'line_id' => $product['line_id'],
                'product_id' => $product['product_id'],
                'product_variant_id' => $product['product_variant_id'],
                'product_desc' => $product['product_desc'],
                'variant_desc' => $product['variant_desc'],
                'quantity' => $product['quantity'],
                'item_total' => $product['item_total']
        )
    );
}

The repeating object is not specified more than once (OrderItemRequest), but instead it is assigned multiple arrays. That caused the object itself to repeat in the xml.

            <orderItems>
                <OrderItemRequest>
                    <line_id>0</line_id>
                    <product_id>A533</product_id>
                    <product_variant_id>A533</product_variant_id>
                    <product_desc>Description</product_desc>
                    <quantity>1</quantity>
                    <variant_desc>Description</variant_desc>
                    <item_total>9.98</item_total>
                </OrderItemRequest>
                <OrderItemRequest>
                    <line_id>1</line_id>
                    <product_id>239</product_id>
                    <product_variant_id>239</product_variant_id>
                    <product_desc>Description</product_desc>
                    <quantity>1</quantity>
                    <variant_desc>Description</variant_desc>
                    <item_total>14.95</item_total>
                </OrderItemR

Question 2

I found this answer from internet and it helps me a lot:

Imagine the request is going to look like this:

XML Diagram 1:

<CountBasketItems>
    <Basket>
        <fruits>
            <fruit>
                <name>Apple</name>
                <color>red</color>
            </fruit>
            <fruit>
                <name>Bananna</name>
                <color>yellow</color>
            </fruit>
            <fruit>
                <name>Apple</name>
                <color>green</color>
            </fruit>
        </fruits>
        <vegetables>
            <vegetable>
                <name>Orion</name>
                <color>yellow</color>
            </vegetable>
            <vegetable>
                <name>Carot</name>
                <color>orange</color>
            </vegetable>
            <vegetable>
                <name>Orion</name>
                <color>red</color>
            </vegetable>
        </vegetables>
    </Basket>
</CountBasketItems>

The real question is: how do I setup my parameter array to accommodate this. The answer:

$fruits = array();
$fruits[] = array(‘name’ => ‘Apple’, ‘color’ => ‘red’);
$fruits[] = array(‘name’ => ‘Bananna’, ‘color’ => ‘yellow’);
$fruits[] = array(‘name’ => ‘Apple’, ‘color’ => ‘green’);

$vegetables = array();
$vegetables[] = array(‘name’ => ‘Orion’, ‘color’ => ‘yellow’);
$vegetables[] = array(‘name’ => ‘Carrot’, ‘color’ => ‘orange’);
$vegetables[] = array(‘name’ => ‘Orion’, ‘color’ => ‘red’);

$basket = array ( ‘fruits’ => $fruits, ‘vegetables’ => $vegetables );

Here is what $basket looks like when I run print_r($basket):

Array
(
[fruits] => Array
(
[0] => Array
(
[name] => Apple
[color] => red
)
[1] => Array
(
[name] => Bananna
[color] => yellow
)
[2] => Array
(
[name] => Apple
[color] => green
)
)
[vegetables] => Array
(
[0] => Array
(
[name] => Orion
[color] => yellow
)
[1] => Array
(
[name] => Carrot
[color] => orange
)
[2] => Array
(
[name] => Orion
[color] => red
)
)
)

Here is a complete example, server and client:

server.php:

configureWSDL('maxfruitwsdl', 'urn:maxfruitwsdl');
// Put the WSDL schema types in the namespace with the tns prefix
$server->wsdl->schemaTargetNamespace = 'urn:maxfruitwsdl';
// Register the data structures used by the service
$server->wsdl->addComplexType(
'Fruit',
'complexType',
'struct',
'all',
'',
array(
'name' => array('name' => 'name', 'type' => 'xsd:string'),
'color' => array('name' => 'color', 'type' => 'xsd:string'),
)
);
$server->wsdl->addComplexType(
'Fruits',
'complexType',
'array',
'',
'SOAP-ENC:Array',
array(),
array(
array('ref' => 'SOAP-ENC:arrayType', 'wsdl:arrayType' => 'tns:Fruit[]')
),
'tns:Fruit'
);
$server->wsdl->addComplexType(
'Vegetable',
'complexType',
'struct',
'all',
'',
array(
'name' => array('name' => 'name', 'type' => 'xsd:string'),
'color' => array('name' => 'color', 'type' => 'xsd:string'),
)
);
$server->wsdl->addComplexType(
'Vegetables',
'complexType',
'array',
'',
'SOAP-ENC:Array',
array(),
array(
array('ref' => 'SOAP-ENC:arrayType', 'wsdl:arrayType' => 'tns:Vegetable[]')
),
'tns:Vegetable'
);

$server->wsdl->addComplexType(
'Basket',
'complexType',
'struct',
'all',
'',
array(
'fruits' => array('name' => 'fruits', 'type' => 'tns:Fruits'),
'vegetables' => array('name' => 'vegetables', 'type' => 'tns:Vegetables'),
)
);

// Register the method to expose
$server->register('CountBasketItems', // method name
array('Basket' => 'tns:Basket'), // input parameters
array('return' => 'xsd:int'), // output parameters
'urn:maxfruitwsdl', // namespace
'urn:maxfruitwsdl#CountBasketItems', // soapaction
'rpc', // style
'encoded', // use
'Return the number of items in the basket' // documentation
);

function CountBasketItems( $basket )
{
return count($basket['fruits']) + count($basket['vegetables']);
}

// This returns the result
$server->service($HTTP_RAW_POST_DATA);
?>

client.php

$fruits[] = array('name' => 'Bananna', 'color' => 'yellow');
$fruits[] = array('name' => 'Apple', 'color' => 'green');

$vegetables = array();
$vegetables[] = array('name' => 'Orion', 'color' => 'yellow');
$vegetables[] = array('name' => 'Carrot', 'color' => 'orange');
$vegetables[] = array('name' => 'Orion', 'color' => 'red');

$basket = array ( 'fruits' => $fruits, 'vegetables' => $vegetables );

print "My Basket:";
echo str_replace(' ', '  ', nl2br(htmlspecialchars(print_r($basket, true))));

// Create the client instance
$client = new soapclient('http://www.modphp.org/nusoap/server.php?wsdl', true);
// Check for an error
$err = $client->getError();
if ($err) {
// Display the error
echo 'Constructor error' . $err . '';
// At this point, you know the call that follows will fail
}

// Create the proxy
$proxy = $client->getProxy();

// Call the SOAP method
$result = $proxy->CountBasketItems($basket);

// Check for a fault
if ($proxy->fault) {
echo 'Faul';
print_r($result);
echo '';
} else {
// Check for errors
$err = $proxy->getError();
if ($err) {
// Display the error
echo '
Error' . $err . '';
} else {
// Display the result
echo 'Result of CountBasketItems';
print_r($result);
echo '';
}
}
// Display the request and response
echo 'Request';
echo str_replace(' ', ' ', nl2br(htmlspecialchars($proxy->request, ENT_QUOTES)));
echo 'Response';
echo str_replace(' ', ' ', nl2br(htmlspecialchars($proxy->response, ENT_QUOTES)));
// Display the debug messages

Question 3

It's seems like you don't have an header base element to your xml:

$orderItemRequest = "";

$orderItemRequest .= "<orderItems>"; //main element comes here

foreach($requestArray as $array) {
    foreach ($array as $key => $val) {
        $orderItemRequest .= $comma."<$key>";

        foreach ($val as $key2 => $val2) {
            $orderItemRequest .= "<$key2>$val2</$key2>";
        }

        $orderItemRequest .= "</$key>";
    }
}

$orderItemRequest .= "</orderItems>"; // closing main element comes here
