php - Symfony2 : How to force download multiple images in one zip file with Ajax -

-

this ajax request :

function downloadzip() {          var searchids = $("#image_id:checked").map(function(){             return $(this).val();         }).get();           $.ajax(             {                 type:'post',                 url: $('#admin_product_zip').text(),                 data: {searchids:searchids},                         success: function(response) {                 }             }         );         return false;         }

and controller method, i'm getting product ids , fetch these id's database, getting proper images paths :

public function zipmultipledownload($data){      foreach($data $product_ind) {         $product = $this->repo->find(3);         $images=$product->getcolorimagespaths();         $itemimages=$product->getitemimagespaths();         $archive_file_name =$product->getname().$product->getid().'.zip';         //print_r($itemimages);         //return new response('test');     }      $this->zipfilesanddownload($images,$archive_file_name,$itemimages);     //return json_encode($itemimages);  } // function dowloading images in zip format public function zipfilesanddownload($file_names,$archive_file_name,$itemimages) {     $zip = new ziparchive();      if ($zip->open($archive_file_name, \ziparchive::create | \ziparchive::overwrite) === true)     {         foreach ($file_names $files) {         // $zip->addfile("uploads/ltf/products/display/web/5232f56d0291a.png","uploads/ltf/products/display/web/5232f56d0291a.png");             $zip->addfile($files['web'], $files['web']);             $zip->addfile($files['iphone'], $files['iphone']);         }           foreach ($itemimages $itemfiles) {             $zip->addfile($itemfiles['web'],$itemfiles['web']);             $zip->addfile($itemfiles['iphone4s'], $itemfiles['iphone4s']);             $zip->addfile($itemfiles['iphone5'], $itemfiles['iphone5']);        }        $zip->close();      }      else {          return "can not open";      }       $response =new response();      //then send headers foce download zip file      $response->headers->set('content-type','application/zip');      $response->headers->set('content-disposition', 'attachment; filename="' . basename($archive_file_name) . '"');              $response->headers->set('pragma', "no-cache");      $response->headers->set('expires', "0");      $response->headers->set('content-transfer-encoding', "binary");      $response->sendheaders();      $response->setcontent(readfile($archive_file_name));      return $response; }

problem : that's getting binary data, special character not images.
images paths propers.

did u add use 

use ziparchive;

in controller , try 1 

$response = new response();  // set headers  $response->headers->set('cache-control', 'private'); $response->headers->set('content-type', mime_content_type($filename)); $response->headers->set('content-disposition', 'attachment; filename="' . basename($filename) . '"'); $response->headers->set('content-length', filesize($filename));  // send headers before outputting $response->sendheaders();  $response->setcontent(file_get_contents($filename));

if still strict matter try remove sendheaders

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
