Magento Update and Clean Shoping Cart using Ajax -


Two days while trying to do me, but failed. I have a code on the server: 

  & lt ;? Php require_once $ _SERVER ['DOCUMENT_ROOT']. '/app/Mage.php'; Dana :: Application (); Dana :: log ('-----'); Dana :: getSingleton ('Checkout / Session') - & gt; SetCartWasUpdated (true); $ Quote = Dana :: getSingleton ('Checkout / Session') - & gt; GetQuote (); Forex Currency ($ quote- & gt; All Matching Items) ($ quote_item) ($ quote_item- & gt; Set (55); } $ Quote-> Save (); Dana: Logon ($ quote_item); $ Session = Dana :: Milensington ('checkout / session'); Forex Currency ($ session-> getQuote () -> join item ($ item)) {$ productid = $ item- & gt; GetProductId (); $ Productsku = $ item- & gt; getSku (); $ Product name = $ item- & gt; Mix (); $ Product cost = $ item-> getQty (); } Dana :: log ('Product:' $ PRODUCTNAME. 'QUOTITION:'. $ PRODUCER); Dana :: log ('-----'); ? & Gt;   
 I have an AJAX request:  
  & lt; script type = "text / javascript" & gt; Function UpdateCart (Product ID, Quality) {qty = jQuery ('# prodqty'). Val () jQuery.ajax ({type: "POST", data type: "HTML", data: {productId: productId, qty: qty} url: "updateCart.php? ProductId =" + productId + "& amp; qty = "+ Qty, success: function (data) {// warning (" success ");}, error: function (data) {warning (" failure ");}}); } & Lt; / Script & gt;   
 and .phtml file:  
  & lt; Id = 'prodqty' onchange = "updateCart (20)" & gt; & Lt; Options & gt; 1 & lt; / Options & gt; & Lt; Options & gt; 2 & lt; / Options & gt; & Lt; Options & gt; 3 & lt; / Options & gt; & Lt; Options & gt; 4 & lt; / Options & gt; & Lt; Options & gt; 5 & ​​lt; / Options & gt; & Lt; Options & gt; 6 & lt; / Options & gt; & Lt; Options & gt; 7 & lt; / Options & gt; & Lt; / Select & gt; SetQty (55) - This is the desired quantity for testing when I select the option through selection, fix the cart updates and log all that has been done well. But when I suppress the volume of the F5 car (not updated in the situation), to check the situation, I am going to the entire .php code (from server) magenta template (cart.php in our case). I was surprised when I press F5 and the car is QTY55 (as desired for me)  
 Question - What do I remember ??? Please help me   
 
 
 You should add these rows:  
  Dana :: getSingleton ('Checkout / cart') - & gt; Save (); Dana :: getSingleton ('Checkout / Session') - & gt; SetCartWasUpdated (true);   
 Instead of  $ quote- & gt; Save ();  (Not sure about this)

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
