php - CodeIgniter session set-cookie duplicated -- how to solve -


update:

I wonder if anyone can review my answer and Can you see if any hole in it

A well documented issue is when using codingers and sessions:

A set in the Summary coding - Cookies each time set_userdata Is called.

I got a partial solution:

The only problem with this solution is that the code needs to be inserted everywhere to clean all the headers An easy way? I have modified the code a bit to remove php errors, but is there any way I can use hooks or something? 

  & lt; Php class extends MY_Controller CI_Controller {public function __construct () {origin: __construct (); } // View (Modified) http://ha17.com/1745-bigip-f5-header-max-size-collides-with-codeigniters-bizarre-session-class/ Protected Function _removeDuplicateCookieHeaders () {// Clean All cookies are set ... $ headers = headers_list (); $ cookies_to_output = array (); $ Header_session_cookie = ''; $ Session_cookie_name = $ this- & gt; Config- & gt; Item ('sess_cookie_name'); Forex currency ($ header as $ header) {list ($ header_type, $ data) = explosion (':', $ header, 2); $ Header_type = trim ($ header_type); $ Data = trim ($ data); If (stroller ($ header_type) == 'set-cookie') {header_remove ('set-cookie'); $ Cookie_value = current (Explode (';', $ data)); List ($ key, $ val) = explosion ('=', $ cookie_value); $ Key = trim ($ key); If ($ key == $ session_cookie_name) {// overwrite (yes, do so!) $ Header_session_cookie = $ data; to continue; } Else {//} is not a cookie related to the session, add it as usual, a CSRF or some other cookie which we might get from $ cookies_to_output $] ARAR ('header_type' = & gt; $ header_type, 'data' = & gt; $ Data) are set; }}} If (empty ($ header_session_cookie)) {$ cookies_to_output [] = array ('header_type' = & gt; 'set-cookie', 'data' = & gt; $ header_session_cookie); } Foreign currency ($ cookies_to_output $ cookie) {header ("{$ cookie ['header_type']}: {$ cookie ['data']}", false); }}}}  
 
 Edit: If you're using $ $ then just use this code- & gt; Load-> (See). If you are using the correct echo in a controller, then it can remove the output before removing the header.  
 Editing requires PHP 5.3 or newer.  
 I have found a way that I feel that I help others with this issue. I have not tested it completely yet, but it seems to work.  
 Application / hook / session_cookie_fixer.php  
  & lt ;? Php class sessioncookiefixer {// View (modified from) http://ha17.com/1745-bigip-f5-header-max-size-collides-with-codeigniters-bizarre-session-class/ Removing function toolbar session () { $ CI = & amp; Get_instance (); // All cookies are set which are clear ... $ headers = headers_list (); $ Cookies_to_output = array (); $ Header_session_cookie = ''; $ Session_cookie_name = $ CI- & gt; Config- & gt; Item ('sess_cookie_name'); Forex Currency ($ header as $ header) {list ($ header_type, $ data) = explosion (':', $ header, 2); $ Header_type = trim ($ header_type); $ Data = trim ($ data); If (stroller ($ header_type) == 'set-cookie') {header_remove ('set-cookie'); $ Cookie_value = current (Explode (';', $ data)); List ($ key, $ val) = explosion ('=', $ cookie_value); $ Key = trim ($ key); If ($ key == $ session_cookie_name) {// overwrite (yes, do so!) $ Header_session_cookie = $ data; to continue; } else {// not a cookie related to the session, add it as usual, a CSRF or some other cookie which we might get from $ cookies_to_output $] ARAR ('header_type' = & gt; $ header_type, 'data' = & gt; $ Data) are set; }}} If (! $ Header_session_cookie) = $ cookies_to_output [] = array ('header_type' = & gt; 'set-cookie', 'data' = & gt; $ header_session_cookie); } Foreign currency ($ cookies_to_output $ cookie) {header ("{$ cookie ['header_type']}: {$ cookie ['data']}", incorrect); }}}? & Gt; Array ('class' = & gt; 'sessioncookiefixer')   
 application / config / hooks.php  
  $ hook ['post_controller'] [] = array ('class' => , 'Function' = & gt; 'deleted duplicate session cookie header', 'filename' = & gt; 'session_cookie_fixer.php', 'filepath' = & gt; hook ',' parameters' = & gt; array ));

Java - Error: no suitable method found for add(int, java.lang.String) -

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. To clarify - this will not be a method error because it is a linked list.

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...
