I'm trying to set cookies for the first time. I've been following the documentation on W3 schools but it doesn't seem to be working for me.
Here is my code (some naming omitted for this example):
$namenospace = 'thisnameexample';
function someSetup($somename){
$nameofcookie = $somename . '_some_value';
if(!isset($_COOKIE[$nameofcookie])) {
$someValue = rand(1, getrandmax());
$cookielastsfor = time() + (86400 * 30);
setcookie($nameofcookie, $someValue, $cookielastsfor, "/");
}
else {
$someValue = $_COOKIE[$nameofcookie];
};
return $someValue;
};
$setSomeValue = someSetup($namenospace);
As you can see, I'm trying to check if a cookie is set, if it is, grab the value and use it, otherwise, set the cookie, then return the value anyway.
For some reason this setcookie() function isn't working. Does anyone have any insight on this?
Possibly worth noting this is a wordpress site if that's relevant?
Thanks!
Edit: have updated as per scope issues highlighted in comments and still not working as intended.
Edit again: definitely not a duplicate. My team and I discovered the issue and would like this unmarked as duplicate so an answer can be given please!
Make sure you are setting your cookies before output. Where are you calling your function?
As an alternative, you could use JS to set a cookie on client side.

We have a system where you can enter your email address. Now, we want that if you request 3 times in a row (without success) that a special value is reported back.
Everything is working, except how to store the count of tries. We're working with Api-Platform.
This means that a Symfony Session should not do the trick. It will probably restart and create a new session after every request.
So, how can we store a count? Here is an example of what we try to achieve with the usage of Symfony Sessions. Any ideas how to store the count? Sessions weren't possible (Maybe wrong implementation) and a database table seems to be a bit excessive.
if(!$session->has('c_tries')) {
$captchaTries = $session->set('c_tries', 0);
}
$captchaTries = $session->get('c_tries');
$new = $captchaTries + 1;
$session->set('c_tries', $new);
if($captchaTries > 2 ) {
....
It is best to solve this on the client side. You can use cookies.
if (!isset($_COOKIE('trakcer']))) {
setcookie ("TryCount", $captchaTries, time() + 3600); /*expires in 1 hour*/
}
I'm having problems to create cookie in Laravel5. The code is below.
$input = $request->input('first');
if($request->hasCookie('first'))
{
return response()->json('ok');
}
else
{
Cookie::make('first', 'first', 1);
return response()->json('no');
}
I also tried this:
public function createCookie(CookieJar $cookieJar)
{
$cookieJar->make('first', 'first', 1);
}
Nothing works for me, can someone illuminate me?
Thanks in advance. When i try to var_dump and get the cookie value it gives me NULL.
By doing this Cookie::make('first', 'first', 1); , you are creating a cookie it doesn't mean it is already set. you have to send cookie with response.
use below code:
$cookie=Cookie::make('first', 'first', 1);
return response()->json('no')->withCookie($cookie);
Cookies are sent only a request after you created them.
An easier way to check if cookie exist or not is to check http headers in the browser or resources->cookies in Chrome.
Also you didn't provide the dd/var_dump code you used or neither why you need to use a new cookie instead of using Laravel Session::flash
I'm having a problem with Symfony creating a new session on each page load, rather than carrying data across requests. The auto_start in the session section in the config.yml is set to false, and regular php sessions work fine. It's only when running in symfony that I get the problem.
For example, I created the test action:
public function sessionTestAction()
{
$s_Response = '<html><head></head><body><p>Foo</p></body></html>'; //Initialize response and headers
$a_Headers = array();
$i_StatusCode = 200;
$oSession = $this->get('session');
var_dump($oSession->all());
if(!$oSession->has('Test'))
{
$oSession->set('Test', 'Bar');
}
$oSession->save();
return new Response($s_Response, $i_StatusCode, $a_Headers);
}
The expected action is, that on the first page load, the var_dump will yield nothing, and that on any subsequent executions, it will contain Test=>Bar. However, it never gets that data across requests.
In addition, it creates a new session id for each request.
I am using Symfony v2.0.15, and PHP v5.4
Anyone have any ideas?
Edit:
I made some progress, I think. I made the following changes to the test action:
public function sessionTestAction()
{
//Initialize response and headers
$oRequest = $this->get('request');
$a_Headers = array();
if (isset($oRequest->headers->all()['cookie']))
{
$a_Headers['Set-Cookie'] = $oRequest->headers->all()['cookie'];
}
$i_StatusCode = 200;
$oSession = $oRequest->getSession();
$oSession->start();
$s_Response = print_r($oSession->all(), true);
if(!$oSession->has('Test'))
{
$oSession->set('Test', 'Bar');
}
$oSession->save();
$oResponse = new Response($s_Response, $i_StatusCode, $a_Headers);
return $this->render('Bundle:Default:index.html.twig', array('response' => $s_Response), $oResponse);
}
Where that twig file has just {{response|raw}}. It now holds the session for 2 out of 3 of the requests. However, on the third request, it's cleared.
Turned out the problem was, someone added a line to set a session cookie whenever the app.php was run, not knowing that symfony handled sessions itself, I guess. Problem solved.
I got this problem a couple times, its very annoying. So, let me describe possible solution.
Open dev environment - yourdomain.com/app_dev.php/ Try to refresh page a couple times. If you see session ID changed each time - it means that sessions are broken.
If you are using chrome (if not - you should, its the best for developers ;) ) - you can open developers tools (click F12).
Next, check Network tab, refresh page and locate your main request.
Check headers for your request - if should see "Cookie:PHPSESSID".
If you dont see - something wrong with cookies. In my case it was
framework:
session:
cookie_domain: mydomain.com
A lot of you are probably aware of the new EU privacy law, but for those who are not, it basically means no site operated by a company resident in the EU can set cookies classed as 'non-essential to the operation of the website' on a visitors machine unless given express permission to do so.
So, the question becomes how to best deal with this?
Browsers obviously have the ability to block cookies from a specific website built in to them. My question is, is there a way of doing something similar using JS or PHP?
i.e. intercept any cookies that might be trying to be set (including 3rd party cookies like Analytics, or Facebook), and block them unless the user has given consent.
It's obviously possible to delete all cookies once they have been set, but although this amounts to the same thing as not allowing them to be set in the first place, I'm guessing that it's not good enough in this case because it doesn't adhere to the letter of the law.
Ideas?
I'm pretty interested in this answer too. I've accomplished what I need to accomplish in PHP, but the JavaScript component still eludes me.
Here's how I'm doing it in PHP:
$dirty = false;
foreach(headers_list() as $header) {
if($dirty) continue; // I already know it needs to be cleaned
if(preg_match('/Set-Cookie/',$header)) $dirty = true;
}
if($dirty) {
$phpversion = explode('.',phpversion());
if($phpversion[1] >= 3) {
header_remove('Set-Cookie'); // php 5.3
} else {
header('Set-Cookie:'); // php 5.2
}
}
Then I have some additional code that turns this off when the user accepts cookies.
The problem is that there are third party plugins being used in my site that manipulate cookies via javascript and short of scanning through them to determine which ones access document.cookie - they can still set cookies.
It would be convenient if they all used the same framework, so I might be able to override a setCookie function - but they don't.
It would be nice if I could just delete or disable document.cookie so it becomes inaccessible...
EDIT:
It is possible to prevent javascript access to get or set cookies.
document.__defineGetter__("cookie", function() { return '';} );
document.__defineSetter__("cookie", function() {} );
EDIT 2:
For this to work in IE:
if(!document.__defineGetter__) {
Object.defineProperty(document, 'cookie', {
get: function(){return ''},
set: function(){return true},
});
} else {
document.__defineGetter__("cookie", function() { return '';} );
document.__defineSetter__("cookie", function() {} );
}
I adapted Michaels codes from here to come up with this.
Basically it uses the defineGetter and defineSetter methods to set all the cookies on the page and then remove the user specified ones, this role could of course also be reversed if this is what you are aiming for.
I have tested this with third party cookies such as Google Analytics and it appears to work well (excluding the __utmb cookie means I am no longer picked up in Google Analytics), maybe you could use this and adapt it to your specific needs.
I've included the part about if a cookies name is not __utmb for your reference, although you could easily take these values from an array and loop through these that way.
Basically this function will include all cookies except those specified in the part that states if( cookie_name.trim() != '__utmb' ) { all_cookies = all_cookies + cookies[i] + ";"; }
You could add to this using OR or AND filters or pull from an array, database, user input or whatever you like to exclude specific ones (useful for determining between essential and non-essential cookies).
function deleteSpecificCookies() {
var cookies = document.cookie.split(";");
var all_cookies = '';
for (var i = 0; i < cookies.length; i++) {
var cookie_name = cookies[i].split("=")[0];
var cookie_value = cookies[i].split("=")[1];
if( cookie_name.trim() != '__utmb' ) { all_cookies = all_cookies + cookies[i] + ";"; }
}
if(!document.__defineGetter__) {
Object.defineProperty(document, 'cookie', {
get: function(){return all_cookies; },
set: function(){return true},
});
} else {
document.__defineGetter__("cookie", function() { return all_cookies; } );
document.__defineSetter__("cookie", function() { return true; } );
}
}
You can not disable it completely but you can override the default setting with .htaccess
Try
SetEnv session.use_cookies='0';
If it is optional for some users don't use .htaccess
if(!$isAuth)
{
ini_set('session.use_cookies', '0');
}
A little bit old but I think you deserve a answer that works:
Step 1: Don't execute the third party script code.
Step 2: Show the cookie banner.
Step 3: Wait until user accepts, now you can execute the third party script code..
Worked for me.
How about not paying attention to hoaxes?
Aside from the fact that this is old news, the text clearly says that it only applies to cookies that are not essential to the site's function. Meaning session cookies, a shopping basket, or anything that is directly related to making the site work is perfectly fine. Anything else (tracking, stats, etc.) are "not allowed" without permission.
I have a strange problem with my cake (cake_1.2.0.7296-rc2).
My start()-action runs twice, under certain circumstances, even though only one request is made.
The triggers seem to be :
- loading an object like: $this->Questionnaire->read(null, $questionnaire_id);
- accessing $this-data
If I disable the call to loadAvertisement() from the start()-action, this does not happen.
If I disable the two calls inside loadAdvertisement():
$questionnaire = $this->Questionnaire->read(null, $questionnaire_id);
$question = $this->Questionnaire->Question->read(null, $question_id);
... then it doesn't happen either.
Why?
See my code below, the Controller is "questionnaires_controller".
function checkValidQuestionnaire($id)
{
$this->layout = 'questionnaire_frontend_layout';
if (!$id)
{
$id = $this->Session->read('Questionnaire.id');
}
if ($id)
{
$this->data = $this->Questionnaire->read(null, $id);
//echo "from ".$questionnaire['Questionnaire']['validFrom']." ".date("y.m.d");
//echo " - to ".$questionnaire['Questionnaire']['validTo']." ".date("y.m.d");
if ($this->data['Questionnaire']['isPublished'] != 1
//|| $this->data['Questionnaire']['validTo'] < date("y.m.d")
//|| $this->data['Questionnaire']['validTo'] < date("y.m.d")
)
{
$id = 0;
$this->flash(__('Ungültiges Quiz. Weiter zum Archiv...', true), array('action'=>'archive'));
}
}
else
{
$this->flash(__('Invalid Questionnaire', true), array('action'=>'intro'));
}
return $id;
}
function start($id = null) {
$this->log("start");
$id = $this->checkValidQuestionnaire($id);
//$questionnaire = $this->Questionnaire->read(null, $id);
$this->set('questionnaire', $this->data);
// reset flow-controlling session vars
$this->Session->write('Questionnaire',array('id' => $id));
$this->Session->write('Questionnaire'.$id.'currQuestion', null);
$this->Session->write('Questionnaire'.$id.'lastAnsweredQuestion', null);
$this->Session->write('Questionnaire'.$id.'correctAnswersNum', null);
$this->loadAdvertisement($id, 0);
$this->Session->write('Questionnaire'.$id.'previewMode', $this->params['named']['preview_mode']);
if (!$this->Session->read('Questionnaire'.$id.'previewMode'))
{
$questionnaire['Questionnaire']['participiantStartCount']++;
$this->Questionnaire->save($questionnaire);
}
}
function loadAdvertisement($questionnaire_id, $question_id)
{
//$questionnaire = array();
$questionnaire = $this->Questionnaire->read(null, $questionnaire_id);
//$question = array();
$question = $this->Questionnaire->Question->read(null, $question_id);
if (isset($question['Question']['advertisement_id']) && $question['Question']['advertisement_id'] > 0)
{
$this->set('advertisement', $this->Questionnaire->Question->Advertisement->read(null, $question['Question']['advertisement_id']));
}
else if (isset($questionnaire['Questionnaire']['advertisement_id']) && $questionnaire['Questionnaire']['advertisement_id'] > 0)
{
$this->set('advertisement', $this->Questionnaire->Question->Advertisement->read(null, $questionnaire['Questionnaire']['advertisement_id']));
}
}
I really don't understand this... it don't think it's meant to be this way.
Any help would be greatly appreciated! :)

Check your layout for non-existent links, for example a misconfigured link to favicon.ico will cause the controller action to be triggered for a second time. Make sure favicon.ico points towards the webroot rather than the local directory, or else requests will be generated for /controller/action/favicon.ico rather than /favicon.ico - and thus trigger your action.
This can also happen with images, stylesheets and javascript includes.
To counter check the $id is an int, then check to ensure $id exists as a primary key in the database before progressing on to any functionality.
For me it was a JS issue.
Take care of wrap function with jQuery that re-execute JS in wrapped content!
You might want to try and find out where it comes from using the debug_print_backtrace() function. (http://nl.php.net/manual/en/function.debug-print-backtrace.php
Had the same problem, with a certain action randomly running 2-3 times. I tracked down two causes:
Firefox add-on Yslow was set to load automatically from it's Preferences, causing pages to reload when using F5 (not when loading the page from the browser's address bar and pressing Enter).
I had a faulty css style declaration within the options of a $html->link(); in some cases it would end up as background-image: url('');, which caused a rerun also. Setting the style for the link to background-image: none; when no image was available fixed things for me.
Hope this helps. I know this is quite an old post, but as it comes up pretty high in Google when searching for this problem, I thought it might help others by still posting.
Good luck

I had a problem like this last week.
Two possible reasons
Faulty routes (DO check your routes configuration)
Faulty AppController. I add loads of stuff into AppController, especially to beforeFilter() and beforeRender() so you might want to check those out also.
One more thing, are where are you setting the Questioneer.id in your Session? Perhaps that's the problem?
Yes, it occurs when there is a broken link in the web page. Each browser deals with it variously (Firefox calls it 2x). I tested it, there is no difference in CakePHP v1.3 and v2.2.1. To find out who the culprit is, add this line to the code, and then open the second generated file in you www folder:
file_put_contents("log-" . date("Hms") . ".txt", $this->params['pass'] ); // CakePHP v1.3
file_put_contents("log-" . date("Hms") . ".txt", $this->request['pass'] ); //CakePHP v2.2.1
PS: First I blame jQuery for it. But in the end it was forgotten image for AJAX loading in 3rd part script.
I had the same problem in chrome, I disabled my 'HTML Validator' add on. Which was loading the page twice
I was having a similar issue, the problem seemed to be isolated to case-insensitivity on the endpoint.
ie:
http://server/Questionnaires/loadAvertisement -vs-
http://server/questionnaires/loadavertisement
When calling the proper-cased endpoint, the method ran once -whereas the lower-cased ran twice. The problem was occurring sporadically -happening on one controller, but not on another (essentially the same logic, no additional components etc.). I couldn't confirm, but believe the fault to be of the browser -not the CakePHP itself.
My workaround was assuring that every endpoint link was proper-cased. To go even further, I added common case-variants to the Route's configuration:
app/config/routes.php
<?php
// other routes..
$instructions = ['controller'=>'Questionnaires','action'=>'loadAvertisement'];
Router::connect('/questionnaires/loadavertisement', $instructions);
Router::connect('/QUESTIONNARIES/LOADADVERTISEMENT', $instructions);
// ..etc
If you miss <something>, for example a View, Cake will trigger a missing <something> error and it will try to render its Error View. Therefore, AppController will be called twice. If you resolve the missing issue, AppController is called once.
