1) Go to main menu and click on tools.
2) Select Options from the menu.
3) One pop-up will opne, now in this pop-up see at the top icons and select Privacy icon.
4) in the History fieldset you will see the drop-down with remember history.
5) Select use custom settings for history.
6) now click on the show cookies button.
7) again new pop-up will open and its give folder tree structure, in that structure find the domain name for which you search cookies.
8) all cookies are store in that, so you can check that cookie is set or not.
document.cookie = ‘cookiename=’ + cookievalue+ ‘,expires=’ + expirydate.toGMTString();
Here cookiename is the name of cookie and the cookievalue is the value which you need to store in the cookie, expires is the expiry data of the cookie.
Now, if you need to set cross-subdomain cookie then use the below code
document.cookie = name+”=”+value+”expires=”+date.toGMTString()+”; path=/;domain=.example.com”;
Here i mention 2 more things which is not available in the first one, this is path and domain. path is the folder path where you need to store the cookie and the domain is the domain name for which you need to set the cookie, please look carefully that i set .example.com value in the domain, here first dot(.) is required if you want to set it for cross- subdomain, if you do not set it then it will not work for cross-subdomain.
if you are creating sub-domain for modules and want to use the same session across all subdomains then you need to setup the configuration.
if you want to set session to access on main domain and sub-domain, that means session access to all sub-domain, i mean sessions across subdomains.
There is three way to set the configuration for this.
1) open php.ini file and search session.cookie_domain, set the main domain there without www, for example your main domain is www.example.com then you need to set session.cookie_domain = .example.com.
2) set using .htaccess file. set php_value session.cookie_domain .example.com in your .htaccess file.
3) using php_ini function you can set. ini_set(‘session.cookie_domain’,’.example.com’ ).
I think there is not any easy way then above three, enjoy the multiple domains……
when you are working with the php, you need to careful in the cookies and sessions, i show you with example that how to set cookie in php.
PHP provide the setcookie() function to set the cookie.
setcookie(cookie name,cookie value,cookie expire date,cookie path,cookie domain,secure)
1) cookie name: This is Required and you can set any name of the cookie.
2) cookie value: This is Required and you can set value of the cookie
3) cookie expire date: This is Optional and you can set when the cookie expires. you can set the time for cookie. if you need to set cookie for 30 days then you set time()+3600*24*30. your cookie will expire when the session end if you do not set this parameter.
4) cookie path: This is Optional Parameter. when you set this parameter its define server path of the cookie, If you need the cookie for entire domain then you set it to “/”. If set to “/example/”, the cookie will only be available within the example directory and all sub-directories of example folder. current directory is the default value for the cookie, if you not set.
5) cookie domain: This is Optional Parameter. Specifies the domain name of the cookie. if you need to set it for main domain and all sub-domain then you can set this as .example.com. if you set www.example.com then its available in the www.example.com only.
6) secure: This is Optional Parameter. This is define for the cookie that should transmitted over a secure HTTPS connection only. if you set it TRUE that define that the cookie will only be set if a secure connection exists. Default value for this parameter is FALSE.
setcookie(‘cookie_user_id’,$_SESSION[“user_id”],time() + (86400 * 365),’/’,’.example.com’);
