CI 3.1.8 set_cookie（）不起作用？

Question

I know there are so many question about this set_cookie() CI, but I can't found the answer, the cookie doesn't showing in Google Cookies Data menu.

I know how to read it, but it doesn't showing at all in the browser cookies data.

in ControllerFile.php

$this->load->helper('cookie');
$cookie = array(
    'name'      => 'pre',
    'value'     => $token,
    'expire'    => 86400 * 7,
);
$this->input->set_cookie(
    $cookie['name'], $cookie['value'], $cookie['expire']
);

The setting in config.php

$config['cookie_prefix']    = 'e_';
$config['cookie_domain']    = '.localhost';
$config['cookie_path']      = '/project.com/catch/';
$config['cookie_secure']    = FALSE;
$config['cookie_httponly']  = FALSE;

This website Project is under project.com folder, this is what it looks like

htdocs/
---- project.com/
-------- catch/
------------ *CI files*
--------- *files*
--------- *files*
---- anotherproject.com/
---- anotherproject.com/
---- anotherproject.com/

But there are no cookie data for [::1] nor .localhost, why does this happening?

I already tried to googled it but can't found the solution, I already tried with

$config['cookie_prefix']    = '';
$config['cookie_domain']    = '';
$config['cookie_path']      = '';
$config['cookie_secure']    = FALSE;
$config['cookie_httponly']  = FALSE;

But it doesn't work either.

Hope this will help you :

Try Using Array Method (Alternative), an associative array is passed to set_cookie:

Replace it

$cookie = array(
    'name'      => 'pre',
    'value'     => $token,
    'expire'    => 86400 * 7,
);
$this->input->set_cookie(
    $cookie['name'], $cookie['value'], $cookie['expire']
);

With this :

$cookie = array(
    'name'      => 'pre',
    'value'     => $token,
    'expire'    => 86400 * 7,
    /* no need to set domain if localhost */
    'domain' => '.localhost',
    'path'   => '/',
    'prefix' => 'e_',
    'secure' => FALSE
);
$this->input->set_cookie($cookie);

To check your cookies

print_r($this->input->cookie());
