jquery - How to keep track of multiple request data from the same user in PHP sessions? -

-

so question little complicated, let me explain. page code running this:

  1. user enters query in search field , clicks submit.

    1.1 jquery loads new body display progress data.

    1.2 jquery calls process.php via ajax , supplies query argument.

    1.3 jquery starts setinterval periodic update grab progress data, stored inside $_session['prog'], , displays it.

  2. when process.php finishes, jquery stops periodic update, displays final information , calls ajax clear $_session['prog'] variable.

at moment progress data stored inside 1 variable, fine far different users concerned (because of different sessions), if same user make multiple requests @ same time, $_session['prog'] variable cross-overwritten.

so far have thought of 2 possiblities distinguish data each request same user (same session)

  1. have jquery generate random string , send query (and hope avoid colission, although unlikely)

  2. make 2 ajax calls, first 1 requesting new_request_id, second 1 sending query , new_request_id parameters.

  3. have ajax return php before finishes(completes).

i need connect each browser window (each request) each running process, cannot send new request id after request has been submitted, because wont know data pick jquery in browser window. btw, change $_session['prog'] $_session[request_id] -> request_id i'm looking for.

it (request_id) last_insert_id(), because im creating new db entries each valid query, don't know how each different user window.

i need advice here. begun code in php, ajax , jquery, don't know sessions. how should solve problem?

sorry lack of code, paste @ request.

you add unique id each request in addition session id. eg. uniqid() in javascript/jquery?

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.
