Array Problem

[a13wes]

I am trying to integrate a shopping basket with google checkout. The information when the checkout button is clicked is sent via hhtp POST to my php file.

Currently the information is in the following format:

Array (
[0] => ShoppingCartEntry Object (
[quantity] => 1
[productID] => 00001
[price] => 4.99
[name] => Full English
[description] => Eggs, Beans, Sheesh Kebab Served with Toast )

[1] => ShoppingCartEntry Object (
[quantity] => 2
[productID] => 0002
[price] => 2.5
[name] => Cheese Salad
[description] => Cheese Salad Sandwich ) )

However google checkout requires it to be:

[item-quantity]
[item-id]
[item-price]
[item-name]
[item-description]

Is there an way to change the label?

I thought it would be something similar to this:

foreach ($entries as $entry) {
$entry->description = $item-description;

}

However this returns 0.

Any help would be appreciated as I have been struggling with this for a week!! 😕

You probably want:

$item->item-description = $entry->description;
// or array notation
$item['item-description'] = $entry->description;

Thanks for your reply.

Using that method returns - Fatal error: Unsupported operand types in ...

However I've not long managed to get it to post to gc by means of a form, with the line:

<input name="item_description_<?php echo $i; ?>" value="<?php echo $entry->description; ?>" />

However as there can be more than one item on a form the form somehow needs to be generated as part of the loop?

So not quite there yet, but making progress!

My mistake, '-' is an illegal character in a variable name ($item->item-description). It should be fine as an array index though.

Hi guys. I seem to have come across another problem!

At the minute I use following:

foreach ($entries as $entry) {

}

to loop through the above array to print all the entries.

The problem I now have is that I wish to allow a number of options to be available for each product in the shopping basket. eg, tea, milk, orange juice...

So in order to do this I need to change the loop so that it creates an entry for each item in the shopping basket array(quantity), not just each productID with a value for quantity...

Could I just change the foreach statement to something like:

foreach ($entries as $entry->quantity) {

}

Or would it be easier to re-arrange some code I have earlier on that creates the entries?

foreach ($values as $element) {

		$nodeName = $element["tag"];

        switch ($element['type']) {

		case 'open':

			if ($nodeName == "SHOPPINGLIST") {
				$this->publicationID = $element["attributes"]["PUBLICATIONID"];		
			}

			if ($nodeName == "ENTRY") {

				$entry = new ShoppingCartEntry();
				$entry->quantity = $element["attributes"]["QUANTITY"];

			}

			if ($nodeName == "ITEM") {

				$entry->productID = $element["attributes"]["PRODUCTID"];
				$entry->price = $element["attributes"]["PRICE"];

				array_push($this->entries, $entry);
			}			

			break;


		case 'complete':

			if ($nodeName == "NAME") {
				$entry->name = $element["value"];
			}

			if ($nodeName == "DESCRIPTION") {
				$entry->description = $element["value"];
			}				

			break;

        }
