Question

Note: This issue is already solved, finally I found that it\'s not cookies problem, the problem is on unserialize() function. The serialized cookie which

Answer 1

While applying solutions we get forgot the basic of Cookies.

Cookies are like headers. Like the headers, it should be sent before any output generates. then only it sets successfully. I have struggled a lot for this problem but when i went through the basics this problem got solved quickly.

this syntax will be enough to solve this problem...

setcookie(
'settings',
serialize($defaultSettings),
time()+3600*24*30,
'/'          // this is the path
);

Answer 2

Probably your server time is not correct therefore Cookeis are not working on server.

Try this:

setcookie("settings", serialize($defaultSettings), 0);

Setting expiration to zero will fix your issue in this case. or update your server time.

Answer 3

Try exit() after the Location-header.

A Location-header does not prevent a PHP-script from executing further instructions, maybe there is something executed after the header that causes the misbehaviour.

Answer 4

Look at both path and domain parameters for the setcookie function. Reference: setcookie @ PHP docs http://php.net/manual/en/function.setcookie.php

Try this to set your cookie:

if ($on_localhost) { // change this
    $domain = '.localhost';
} else {
    $domain = '.webhoster.com'; // change this
}
setcookie(
    'settings',
    serialize($defaultSettings),
    time()+3600*24*30,
    '/',          // this is the path
    $domain       // this is the domain
);

Good luck!

Answer 5

Only initialize the ob_start() method before setcookie(). most of the developer ob_start() method include in config file.

Answer 6

Try this:

setcookie("settings", serialize($defaultSettings), time()+3600*24*30, '/'); // added path

Also, could it be that serialize($defaultSettings) result is too large?
