Class: AmazonQuery

An AmazonQuery object can be used for lite searches, using liteQuery(), heavy searches, using heavyQuery(), or queries to a Remote Shopping Cart, using one of the functions for this purpose (newCart(), addToCart(), modifyCart, removeFromCart(), clearCart() and getCart()).

This function is used to add items to an existing Remote Shopping Cart. To create a new shopping cart take a look at newCart().

If you do not provide the $cartID and $HMAC parameters, or if these are equal to a blank string, this function behaves exactly like newCart().

Example:

 $items = array();
 $items[] = array("B00005JMEW", 1);
 $items[] = array("1932273271", 2);
 
 $cart = $aq->addToCart($items, "us", $_SESSION['cartID'], $_SESSION['HMAC']);

Parameters:

This function is used to retrieve an existing Remote Shopping Cart. Note that every other action (new, add, modify, remove and clear) will also return the contents from the cart, therefore you only need to use this function if you want to retrieve a cart without mofifying it.

Example:

 $cart = $aq->getCart($_COOKIE['cartID'], $_COOKIE['HMAC'], "de");

Tags:

Parameters:

Example:

 $books = $aq->getCategory("books", "uk");
 
 for($i = 1; $book = $books->getDetails($i); $i++){
   echo $book->getProductName() . "<br>";
 
   echo $book->getAuthors(2) . "<br>";
 }

Parameters:

Products obtained from a heavy request are stored in objects of type HeavyDetails, and can contain all the attributes defined in this kind of objects, athough this is not necessarily the case.

Although this function can return ProductInfo or BlendedSearch objects based on the kind of search you are doing, these objects will only contain HeavyDetails objects, and in no case LiteDetails objects.

Parameters:

Products obtained from a lite request are stored in objects of type LiteDetails, and can contain all the attributes defined in this kind of objects, athough this is not necessarily the case.

Although this function can return ProductInfo or BlendedSearch objects based on the kind of search you are doing, these objects will only contain LiteDetails objects, and in no case HeavyDetails objects.

Parameters:

This function is used to modify the quantities of items you have already added to a Remote Shopping Cart. To create a add new items to a cart take a look at addToCart().

You must provide an array of items to be modified. This array must contain Item IDs of products already in the shopping cart, associated with their new quantities.

Example:

 $noOfModItems = $_POST['noOfItems'];
 $items = array();
 
 for($i = 0; $i < $noOfModItems; $i++)
   $items[] = array($_POST['itemID'.$i], $_POST['qty'.$i]);
 
 $cart = $aq->modifyCart($items, "us", $_POST['cartID'], $_POST['HMAC']);

Tags:

Parameters:

This function is used to add items to an new Remote Shopping Cart. To add items to an existing shopping cart take a look at addToCart().

You must recover the new cart's ID and HMAC by using methods getCartID() and getHMAC(), in order to modify it using functions addToCart(), modifyCart, removeFromCart(), clearCart() and getCart().

Example:

 $items = array();
 $items[] = array("B00005JMEW", 1);
 $items[] = array("1932273271", 2);
 
 $cart = $aq->newCart($items, "jp");

Parameters:

This is the "low-level" method used to query AWS. Methods such as getCategory(), getBrowseNode(), liteQuery(), or heavyQuery(), all call this method. As a matter of fact, you should rather use one of the aforementioned methods unless you feel quite confortable with amazOOP.

Tags:

Parameters:

Like query(), this is a "low-level" function, therefore most users will prefer to use the Remote Shopping Cart with newCart(), addToCart(), modifyCart, removeFromCart(), clearCart() and getCart().

Tags:

Parameters:

You must provide an array of items to be removed. This array must contain Item IDs of the products you wish to remove from the shopping cart.

Example:

 $items = array();
 
 for($i = 0; $i < $_POST['noOfItems']; $i++)
   $items[] = $_POST['itemID'.$i];
 
 $cart = $aq->removeFromCart($items, "us", $_POST['cartID'], $_POST['HMAC']);
