Changed cookie domain, but old cookie is still used

By User



EDITED, look at the end





I got a Symfony 1.2 project, that was running on two domains (different app used on each domain) : www.mywebsite.com and abonnement.mywebsite.com





I had two different cookie name/domain in each app.





We decided to use the same cookie for both apps. So, i edited the config for both apps and set the cookie_domain to .mywebsite.com, and setted the cookie_name to mywebsite_cookie in boths apps.





The problem is that when I visit abonnement.mywebsite.com, the old cookie is used. Manually deleting this cookie in my browser fixes the problem, but there are thousands of users on this website and I'm wondering if there's a solution to manually delete this cookie.





I tried :







if (isset($_COOKIE['abonnement_cookie'])) {

    ini_set('session.cookie_domain', 'abonnement.mywebsite.com);

    setcookie('abonnement_cookie', '', time() - 3600, '/');

    $this->redirect('@internet_etape_1');

}







But no success.





Is there a way to do it?





I'm using Firefox 9.0.1





Thanks!





Edit:





I found the problem, cookie was created with "host" and not "domain".





To use the current host, you need to specify '' as domain :







setcookie('abonnement_cookie', 0, time() - 3600, '/', '');







Hope this helps!

    You need to match the domain and path that which was used to create the cookie when destroying the cookie. This is because as you have discovered, it is possible to have a cookie with the same name and different scopes for the same domain. When destroying the cookie, you must match the scope that was used to create it, so the client knows which one to destroy.

    Try:

    setcookie('abonnement_cookie', '', time() - 3600, '/', 'abonnement.mywebsite.com');

Why is this Javascript much *slower* than its jQuery equivalent?

By User
I have a HTML list of about 500 items and a "filter" box above it. I started by using jQuery to filter the list when I typed a letter (timing code added later): $('#filter').keyup( function() { var jqStart = (new Date).getTime(); var search = $(this).val().toLowerCase(); var $list = $('ul.ablist > li'); $list.each( function() { if ( $(this).text().toLowerCase().indexOf(search) === -1 ) $(this).hide(); else $(this).show(); } ); console.log('Time: ' + ((new Date).getTime() - jqStart)); } ); However, there was a couple of seconds delay after typing each letter (particularly the first letter). So I thought it may be slightly quicker if I used plain Javascript (I read recently that jQuery's each function is particularly slow). Here's my JS equivalent: document.getElementById('filter').addEventListener( 'keyup', function () { var jsStart = (new Date).getTime()...

Is it possible to have IF statement in an Echo statement in PHP

By User
Thanks in advance. I did look at the other questions/answers that were similar and didn't find exactly what I was looking for. I'm trying to do this, am I on the right path? echo " <div id='tabs-".$match."'> <textarea id='".$match."' name='".$match."'>". if ($COLUMN_NAME === $match) { echo $FIELD_WITH_COLUMN_NAME; } else { } ."</textarea> <script type='text/javascript'> CKEDITOR.replace( '".$match."' ); </script> </div>"; I am getting the following error message in the browser: Parse error: syntax error, unexpected T_IF Please let me know if this is the right way to go about nesting an IF statement inside an echo. Thank you.
