php - CodeIgniter Shopping Cart Strange Behaviour -

-

i have strange behaviour of codeigniter's shopping cart class. have set ci_session table in database , have changed sess_use_database true.

what happening when add items shopping cart fine: see total items counter going , everything. when go shopping cart page first time see items there, should be. have provided delete item button , empty cart button. strange things happen here: when click remove item, page refreshes (due redirect think) item still there! if manually refresh page of cart, see same item had removed disappear. it's like, when use redirect, cache of page, not actual page fresh information on it.

anyway, here links:

try add items page: http://www.pantanishoes.it/niko/index.php/store/linea/urban clicking on big dark button on bottom of every item description.

then try go carrello on menu on top , try delete of items or svuota(which simple destroy()) , see happens! appreciated! in advice!

here code of cart.

function add() {      $item = $this->store_model->get_item($this->input->post('id'));      $data = array(         'id' => $this->input->post('id'),         'name' => $item->modello,         'qty' => $this->input->post('qty'),         'price' => $item->prezzo,         'options' => array(             'taglia' => $this->input->post('taglia'),             'linea' => $item->linea,             'modello' => $item->modello,             'foto' => $item->foto1             )     );      $this->cart->insert($data);      $linea = str_replace(' ', '-', $item->linea);      redirect('/store/linea/' . $linea . '/', 'location'); }  function remove() {     $rowid = $this->uri->segment(3);     $data = array(         'rowid' => $rowid,         'qty' => 0     );      $this->cart->update($data);     redirect('cart'); }  function destroy() {     $this->cart->destroy();     redirect('cart'); }

on localhost working great! when loaded website server, started have issues. really strange! there config thing i'm missing?

chrome says: request url:http://www.pantanishoes.it/niko/index.php/cart/remove/fb1b4a9869de6f24aa620e2307192d93 request method:get status code:302 moved temporarily (from cache)

ok guys. fixed little bug of friend of mine has used ci while. of guessed, cache problem. thing need force php headers so:

header( 'expires: sat, 26 jul 1997 05:00:00 gmt' );  header( 'last-modified: ' . gmdate( 'd, d m y h:i:s' ) . ' gmt' );  header( 'cache-control: no-store, no-cache, must-revalidate' );  header( 'cache-control: post-check=0, pre-check=0', false );  header( 'pragma: no-cache' );

you can private function in controller it's not accessible outside , call in relative add, delete, destroy methods. private function must this:

private function _set_headers() {     header( 'expires: sat, 26 jul 1997 05:00:00 gmt' );      header( 'last-modified: ' . gmdate( 'd, d m y h:i(worry)' ) . ' gmt' );      header( 'cache-control: no-store, no-cache, must-revalidate' );      header( 'cache-control: post-check=0, pre-check=0', false );      header( 'pragma: no-cache' ); }

and call inside other functions so:

$this->_set_headers();

remember work in scope of class. can't call function in other controllers , can't accessed outside scope, cause it's not public.

thanks all!!

c++ - Function signature as a function template parameter -

-
i'd use function signature template argument. works great classes, when try same trick function templates, msvc throws error: error c2768: 'func' : illegal use of explicit template arguments here's code: template <typename signature> void func(); template <typename r, typename a1> void func<r(a1)>(); what should make work? you cannot partially specialize function template, not supported language. can create partially specialized class template static member function, , possibly trampoline function instantiate class template , invoke static function. something this: namespace detail { template<typename signature> struct helper; template<typename r, typename a1> struct helper<r(a1)> { static void call() { // stuff r , a1... } }; } template<typename signature> void func() { detail::helper<signature>::call(); }

algorithm - What are some ways to combine a number of (potentially incompatible) sorted sub-sets of a total set into a (partial) ordering of the total set? -

-
i have sorting problem i'm pretty sure doesn't have canonical "answer" - has number of different approaches, each pros/cons. i'm interested in hearing different approaches. suppose bunch of people {p_i | i=1,...,m} ranking favorite ice cream flavors. in total there n different flavors, single person p_i ranks n_i << n flavors or familiar with. i'm interested in combining these sub-rankings plausible overall ranking of n flavors. for concrete situation: m , n both 1000 (by coincidence), , each n_i 20 . can assume there's enough overlap in flavors people rank such no flavor "isolated". again, i'm interested in hearing different ways approach this, if there isn't single clear answer. thanks! one way approach problem construct directed cyclic graph representing of constraints on ordering of elements. nodes in graph represent different elements compared , have edge first node second node if had ranked first e...

there's function on page want call after loads. not own page, can't insert html it. can please provide specific examples how chrome extension or greasemonkey?
