jquery - Magento php add to cart with Custom price -


i have following issue: make calculations via jquery in frontend , want add product cart price calculated in frontend.

i wrote custom module ajaxcontroller achieve adding cart part, know struggle setting custom price.

my script looks this:

$_prod = json_decode(mage::app()->getrequest()->getpost('zapfsaeule_product'));      $id = 347; // there 1 bundle product added cart  viar scipt, static id enough.      $params = array(         'product' => $id,         'related_product' => null,         'bundle_option' => array(             6 => 17, // static options testing purpouses             5 => 13), //          'qty' => 1 // static qty testing     );      $cart = mage::getsingleton('checkout/cart');      $product = new mage_catalog_model_product();     $product->load($id);      $cart->addproduct($product, $params);     $cart->save();      mage::getsingleton('checkout/session')->setcartwasupdated(true);      $this->getresponse()->setbody('true'); // setting response true, because ajax request.     $this->getresponse()->setheader('content-type', 'text/plain');

that's code adding product. setting price tried approach mentioned in thread on stackexchange: https://magento.stackexchange.com/questions/4318/dynamically-calculated-prices-save-before-add-to-cart

but didn't work. guess event observed here doesn't occur in case, because wrote custom script.

but there still problem, if observer approach work, how pass calculated price observer?

i hope understand problem , can me solve it.

thanks in advance!

best regards, martin

reading through mage_checkout_model_cart::addproduct(), there doesn't appear way set item's price parameters. instead, you'll need add product, grab resulting item, , set price:

$cart->addproduct($product, $params)     ->save();  // grab corresponding item $item = $cart->getquote()->getitembyproduct($product);  // set custom price $item->setoriginalcustomprice($customprice)     ->save();

haven't had time try out, should right idea. make sure set original_custom_price field (using setoriginalcustomprice()), not 1 of other prices. other prices recalculated during totals process.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
